INTRODUCTION

The SI-1 Sensor Interface Module converts the analog output of proximity sensors (SE 2814A and

2815A) to digital outputs so that an ACU (SE 422 Access Control Unit) can identify people who

present the proper credentials. You should read this manual before you begin installing the

equipment.

Caution

The SE 422 ACU may have either of two Sensor Interface Modules, an SI-1 and an SI. These are

not interchangeable. If you attempt to replace an SI-1 with an SI without making the necessary

corrections, you will destroy the SI-1 PCB. Refer to Figure 1-1 for wiring information.

Scope

This manual describes the hardware installation, wiring, database setup, and maintenance

procedures necessary for operation of the SI-1 Sensor Interface and SE 2814A and SE 2815A

Proximity Sensors with the SE 422 ACU (Figure 1-2). This manual also assumes that the SE 422

is installed. Note that the manuals included with the SE 422 cover overall system operation and

the installation of the VIP2 (Verified Identification of Personnel) keypads and magnetic stripe

readers.

SECTION 2: MOUNTING

2-1

INTRODUCTION

Use the following section to mount the SI-1 Sensor Interface Module and its components.

MOUNTING THE ENCLOSURE

Remove the enclosure (metal box) from its shipping container and plan its installation. Do not

install the SI-1 at this point. Plan that the location for the enclosure be in a secure but accessible

place. It should be protected from the weather (refer to Appendix A for more details). It should

be as close as practical to the SE 28XX sensor in order to keep the coax cable as short as

possible—no more than 250 ft (76 m) maximum.

Normally, the hinge on the enclosure door is on the left and wires enter the enclosure through the

knockouts in the top or on either side (Figure 2-1). If conduit is already in place so that wires must

enter from the bottom, you should turn the enclosure over so the hinge is on the right. Avoid using

what would normally be the bottom knockout (the knockout closest to the ground screw hole in the

enclosure); clearance is minimal between it and connectors on the PCB.

Figure 2-1. Enclosure for the SI-1

2-2

Section 2: Mounting Components SI-1

Remove the knockout (s) from the enclosure for the coax cable to the SE 28XX sensor, for device

network data and power cable (s) to the SE 422 and to any other device that will be connected to

the SI-1.

Screw or bolt the enclosure in place and connect the conduit to it. If there is no conduit connected

to the enclosure or the conduit system will not provide an adequate earth ground connection, run

a bare or green ground wire to the enclosure from the building or from the computer system�s

grounding electrode. Note that the enclosure must be securely earth grounded. Use strain relief

cable clamps in knockouts if conduit is not used.

Install the No. 6 grounding screw (included in the bag of hardware) through the hole provided in

the enclosure. Tighten one of the supplied nuts on the inside of the screw so that the captive

washer bites through the paint on the enclosure.

Install the tamper switch on the enclosure according to the instructions in the bag with the switch.

MOUNTING THE SI-1

Caution

Components on a PCB (Printed Circuit Board) may be destroyed by inadvertent discharge of static

electricity. To reduce the potential of electrostatic discharge, each PCB is shipped in a protective

bag. Leave the PCB in the protective bag until you are ready to install it. Before removing a PCB

from its bag, touch a grounded object to discharge any static electricity that may have accumulated

on you or your clothing. If possible, ground yourself with a wrist-strap clip lead while installing the

PCB. To minimize static electricity, keep away from vinyl or other plastic and move as little as

possible while on carpets. Handle the PCB by it edges only. Do not touch exposed circuity or

connector pins, and do not rest the board on a metal surface.

1. Remove the PCB from its bag.

2. Connect the free end of the grounding jumper that is attached to the mounting plate on the

sensor interface module to the grounding screw. Also connect the bare or green-grounding

wire (if any) to the grounding screw and screw on, but do not tighten the other supplied nut.

3. Line up the holes in the SI-1 mounting plate with the standoffs in the enclosure and snap the

SI-1 in place in the enclosure.

5. Insert the crimped leads from the tamper switch into positions 5 and 6 of the 6-pin Phoenix

connector and tighten, ensuring that the leads are secure. Refer to Figure 2-2 for information

about using Phoenix connectors.

6. Plug the Phoenix connector into connector J1 on the SI-1 PCB.

2-3

Section 2: Mounting ComponentsSI-1

Figure 2-2. Typical Phoenix Connector

MOUNTING THE SE 28XX SENSORS

Use the following information to mount the SE 28XX sensors.

1. Remove the SE 28XX sensor form the packaging and inspect it for any defects.

2. Install the sensor as close as possible to the door handle on the entry where people can easily

use it, about the same height as the door handle (Figure 2-3).

3. Install the sensor on, in, or behind any nonconductive material. Note that in low-risk

installations, surface mounting is permissible. However, for greater security, install the

sensor in or behind a wall (Figure 2-4).

n If a sensor is installed behind something, the distance between its face and the outside

surface should be less than about an inch (2.5 cm). Sensors work best when command keys

are presented within 3 in (7.6 cm) of them.

n A sensor cannot read command keys through conductive materials like metal siding,

insulation foil, expanded metal lath, safety wire mesh within glass or even some types of

metallic coatings on glass. Any conductive material (foil, metal mesh stucco lath, concrete

reinforcing steel, power wiring, metal door jambs and casing, metal siding, structural beams)

closer than about 4 in (10.2 cm) to a sensor edge will reduce the read range.

2-4


Figure 2-3. Example of a Sensor Installation

Figure 2-4. Sensor Mounted in Side a Wall

2-5


n If conductive material is along one edge only, operation will usually be satisfactory if the

sensor edge is at least 1 in (2.5 cm) from it. If conductive material is on all sides, maintain

at least 3 in (7.6 cm) all around. If the wall surface is conductive, you can either cut a hole

in it at least 14 x 14 in (35.5 cm x 35.5 cm) and center the sensor on a nonconductive area,

or mount the sensor at least 1.5 in (3.8 cm) in front of it with a standoff such as the SE 2700

(Figure 2.5).

Figure 2-5. Sensor Mounted on a Standoff

n If the sensor will be hidden, mark the location of its center with a decal so keyholders will know

where to present their command keys. Also, provide a removable access panel on the secure

side of the wall for installation and service.

n If neither side of the wall is secure, you may be able to install the unit in a slot in the wall and

provide access to it through a removable section of the door jam (Figure 2-6).

n The SE 28XX sensors can tolerate temperatures between -46oC (-50oF) and 82oC (180oF)

and are weather resistant. Sensors absorb solar radiation because of their dark color, and

in strong, direct sunlight, they can overheat and cause a temporary malfunction or permanent

damage. Shade them from the hottest afternoon sun.

n If the installation will be subject to the weather where moisture could collect on the cable and

run down to the connector, plan to orient the sensor so the connector will be on the side or

bottom, rather than the top. Also, plan to route the cable so you can provide a drip loop in

the cable that is lower than the connection point.

2-6


Figure 2-6. Sensor Mounted in Door Jam Slot

n If you mount an SE 2814A sensor on the surface of a wall, you will need to drill a hole to

accommodate the connection of the coax cable. Do not use the SE 2815A Sensors in high

risk surface mount installations. The cable would be exposed.

n The SE 28XX sensor is an antenna. Sources of electrical noise, such as nearby power lines,

RF test equipment, any kind of RF communications antenna, and data cables, particularly

those running around the door jamb, can cause false key reads.

4. Attach the sensor by using one of the following methods:

A. On Glass or other smooth surfaces, tape the sensor in place with double-side tape. Any

nonconductive adhesive will also work. If the coaxial cable connection to the sensor will

be inaccessible after installation, do not permanently fix the sensor in place (with tape

or adhesive) until after making the connection.

2-7


B. On rough surfaces or where additional security is necessary, use bolts. Carefully drill

through the four corners at the locations marked on the sensor with a drill no larger than

#8 (0.199�). Then, using the template supplied with the sensor, drill the surface behind

it (four holes in a square, a sensor into misplaced holes will break the sensor housing).

If possible, drill through the wall and use standard #10 (3/16�) roundhead or panhead

bolts and nuts. Do not attempt to countersink flathead bolts in the plastic sensor

housing. Stake the nuts, or use jamb nuts so no one will be able to remove the bolts

from the outside. Drill for masonry anchors in thick masonry. In exposed and high risk

areas, you may want ot use special screws providng more security against potential

tampering.

2-8


SECTION 3: WIRING

3-1

INTRODUCTION

Connections and wiring procedures for the SI-1 are as follows:

Routing Coaxial Cables

Route the coax cable, SE 9284 (SE 9284-DB for wet or all-weather environments), between the

SI-1 and the SE 28XX sensor before installing connectors on the ends. Keep the run as short as

possible; 6 to 10 feet (2 to 3 m) will be enough in may cases; 250 ft (76 m) is the limit.

Keep the cable away from conductors carrying power line voltages, high current, audio signals for

paging speakers, or RF in the 1 to 30 MHz range. Shielded power, data, monitor, lock, and relay

wiring from the SE 422 or the SI-1 in the same conduit will not normally cause problems. Avoid

cable splices, bends sharper than 2� (5 cm) diameter, and anything which pinches or distorts the

cable.

Do not use metal cable clamps or ties. If you must splice the coax (one splice per cable maximum),

use F81C type cable connectors only. Cover the splice connectors with heat-shrink tubing or

electricians�s tape.

Inserting Coax Cable Connectors (Figure 3-1)

1. Slip the large metallic-colored outer clamp ring over the cable.

2. Strip off about 3/4� (1.9 cm) of the outer insulation jacket. (Do not damage braid under it.)

3. Fold the braid back over the outer insulation jacket.

4. Strip off about 5/8� (1.58 cm) of the inner insulation (do not nick the center conductor).

5. Push the connector under the braid as far as possible and trim off the folded-back braid.

6. Slide the outer ring up and crimp it in place using a hex crimp tool. Note that the middle jaw

(0.324�) is best for this purpose.

7. Clip the inner conductor off so it extends about 1/16� (1.588 mm) beyond the end of the

connector.

8. Connect the SI-1 end of the coax to the angle connectors.

9. Screw angle connector to J6 on the SI-1 PCB.

10. Connect the other end of the coax to connector on the sensor.

11. Tighten with a 7/16 open-end wrench (use silicon grease to lubricate and seal joint).

Data and Power Network Wiring

If the SE 422 is not installed, install it now; refer to its installation and operation manual, P/N

66107567001. The following steps refer to connections at the SI-1 Sensor Interface module.

Pull the device data and power cable from the SE 422 to the SI-1. Westinghouse Security

Electronics recommends four-conductor, 18 gauge shielded cable (Figure 3-2) such as Alpha

5164 or Manhattan M5394 for general purpose data and power wiring, and 1000 ft (305 m) as the

maximum network length from end to end.

n If your system consists of an SE 422 and a single SI-1, the SE 422 will be located on one end

of the network and the SI-1 will be on the other end.

n If your system includes another SI-1, or one or more VIP2 keypads or magnetic strip readers,

they will be daisy chained on the same network.

n If the system consists of one SI-1 and one or more other devices (VIP2 and/or MSR), pull a

cable from the SE 422 to the SI-1 and connect the other devices on a separate cable from

the SE 422.

n If the system includes two SI-1s, run separate cables from the SE 422 to each SI-1.

n If the system includes two SI-1s and one other device, run one cable from the SE 422 to each

SI-1. You can then continue on from one SI-1 to the other device, or run through the other

device on the way to the SI-1. In general, keep wiring as short as possible to the SI-1.

n If the system includes two SI-1s and two other devices, place one of the other devices on each

cable run from the SE 422.

n Any cable, either to the SE 422 or to another device, must be long enough in the SI-1

enclosure to loop near the grounding screw on the way to connectors J2 and/or J3.

Connectors J2 and J3 on the SI-1 PCB, and P7 and P8 on the SE 422 PCB are equivalent

and interchangeable. You can use either connector for one cable or both connectors for two

cables.

Connecting Cable Shield to the Enclosure

Note

If you do not have enough cable to pass the ground screw on the way to J2 or J3, you can drill a

hole in the enclosure and install a second ground screw near the knockout where the cable enters.

Remove the SI-1 PCB first to avoid possible damage to it and to prevent metal chips from falling

on it.

Section 3: Wiring

3-4

SI-1

Figure 3-2. Connecting Shield to the Enclosure

1. Strip the cable outer insulating jacket (not shield braid) back to the ground screw.

2. Slip the orange outer shield-kon sleeve over the cable and push it back onto the cable jacket.

3. Push the shield braid back to form a fat ring about half an inch from the end of the insulating

jacket.

4. Trim the ring carefully and remove excess braid (braid should extend a half inch).

5. Loosen the braid (if necessary) and slip the green inner shield-kon sleeve under it.

6. Lay the stripped (and tinned) end of one of the ground pigtails on the exposed braid.

7. Position the orange sleeve over the braid and pigtail end, and crimp the sleeve in place.

8. Trim the braid for a neat installation. The inner sleeve protects the wires from being crushed,

so the sleeve assembly should remain loose, attached to the braid only, not the wires inside

cable. The final assembly should be as shown in Figure 3-3. Note that you can install the

pigtail coming out of the back of the sleeve if it will make reaching the ground screw easier.

9. In an emergency (if the shield-kon sleeves are not available), strip the cable outer jacket.

10. Loosen the braid (by shoving it back) enough to spread a hole in it.

11. Bend the cable in order to pull a loop of the conductors through.

12. Cut the braid to the right length (no more than 2� (6.35 cm) to reach a ground stud or screw.

13. Crimp a ring lug on the end of the braid.

3-5


Figure 3-3. Shield-kon Sleeve Installation

14. Remove the foil covering and the loose strings from the conductors. Do not cut the shield-

drain lead.

15. Place the ring lug (on the pigtail or the end of the braid) over the ground screw on the SI-1

enclosure along with the grounding jumper and the bare or green enclosure grounding wire

(if any).

16. Tighten the nut on the screw.

17. If the cable is not in conduit, tighten the strain relief cable clamp just enough to hold the cable

in place; do not overtighten.

Section 3: Wiring

3-6

SI-1

Installing the Conductors in J2 and/or J3

Caution

To avoid RF radiation and to meet FCC requirements, all wiring from the SE 422 must be shielded

or in metal conduit. If you are adding SI-1/SE 28XX proximity capacity to an existing SE 422 system

that does not use shielded cable, you must replace all non-shielded wiring with shielded cable. Use

the procedure outlined above on all cables in the SE 422 enclosure. Use the grounding stud in the

SE 422 enclosure instead of the grounding screw described for the SI-1. Similar shield connection

techniques must also be used in VIP2 Keypads. At magnetic strip readers, connect both the shield

and the shield drain to the brown lead.

Connect the shield drain lead to earth ground (pin 5, J2 or J3 on the SI-1 PCB).

Westinghouse recommends the following procedure. (This avoids tinning wire ends with solder

in the field, which would otherwise be required for UL certification, and provides a much more

secure and reliable installation.)

1. Strip the wire ends at least 3/8� (9 mm); use the length of the bare metal on the crimp sleeves,

as a guide. A stripping tool such as the Weidmuller Stripax (cat. #90050.0) or Mini Stripax

(cat. #90012.8) is recommended for stripping insulation accurately without cutting wire

strands.

2. Twist the exposed strands tightly and crimp a sleeve (such as Weidmuller H 0.5 through H

4.0 series insulated crimp sleeves on the ends of the wires with a tool such as Weidmuller

PZ4 (cat. #90125.0). Be sure the sleeves are crimped on bare conductor metal, not the

insulation. Use yellow sleeves on single 18-gauge wires and blue sleeves when two 18 gauge

wires will go in a single position (Figure 3-4).

3. Put the crimp sleeve in place in the connector (Table 3-1).

4. Tighten the binding screw, wiggle and gently pull on the wires, and tighten the screw again.

5. On the SI-1 PCB, set the slide switch SW1 to the EC-NET position.

6. Set hex switch SW2 to represent the SI-1 serial number (0 to 15 corresponding to 0 to F on

the switch. Each SI-1 must have a different setting when connected to an SE 422.

7. Connect the other end of the device network cables similarly at the SE 422 (Table 3-1).

8. Terminate both ends of the data network with a 120 ohm resistor. If the SE 422 or and SI-

1, VIP2 Keypad, or a Magnetic Stripe Reader has only one device network cable running to

it, connect a 120-ohm resistor between DATA A(+) and DATA B(-). Use the empty network

connector on an SI-1 or VIP2. Do not connect the resistor where two device network cables

connect.

Power Inserter Wiring

The SE 422 system with the proximity option is FCC certified only when powered by an SE Power

Inserter (PI). Westinghouse Security Electronics recommends that you use a PI power supply.

Install and connect the PI to the SE 422 as follows (Table 3-2):

1. Arrange for a dedicated AC circuit with a reliable connection at the receptacle to the building

(or computer system) grounding electrode.

2. Install the PI in a secure area protected from weather and temperature extremes. Be sure

that air can circulate around it freely and that the PI power cord is long enough to reach the

receptacle—never use extension cords.

3. Pull shielded cable between the PI and the SE 422.

n You will need two conductors for PWR+ and PWR-. You will need two more if the PI will be

providing lock power and another two if the PI power fail monitor will be connected to the SE

422. The power fail monitor, like the tamper switches, requires setup with a terminal. It is

useful only if standby batteries are connected.

4. Connect shields at the SE 422 as described above. Connect shields at the PI to one of the

cover screws on either side of the output connectors. The drain wire may be connected to

the cover screw or cut off.

4-1

INTRODUCTION

At start-up, a new SE 422 reads the serial numbers of devices connected to plugs P7 and P8 on

the SE 422 PCB. The serial numbers are stored permanently in a data base, even if power fails.

Any changes made in those original devices, adding or removing a device, or replacing one device

with another of the same or different type, and the SE 422 database must be reset. This setup

procedure can be performed from the SE 422 front panel or from a terminal keyboard connected

to the system.

Database Setup from the Front Panel

To setup the SE 422 database from the front panel proceed as follows:

1. To read the serial numbers, first set the configuration DIP switches of SW2 on the SE 422

PCB so the SE 422 can recognize the new devices that you intend to connect. Note that

depressing the lower end of the rocker (closest to the heat sink and memory backup battery)

sets the switch to off. Switches 1, 2, and 3 select the devices for Entry 1. Switches 4, 5, and

6 select the devices for entry 2 (Table 4-1).

Note

Always leave DIP switch 7 off and switch 8 on. Switches 7 and 8 connect the memory backup

battery in order to protect the system database in case of a power failure.

2. When the switches are set to match the devices (s) that you intend to connect, log on at the

SE 422 front panel and enter the 9901 command. This instructs the SE 422 to read the

switches. (Refer to the SE 422s operations manual for log in instructions.)

3. Shut off power and unplug connectors P7 and P8 on the SE 422 PCB. Apply power and wait

60 seconds for the SE 422 to record everything as off line.

4. Remove the serial numbers of the old devices from the SE 422 memory.

a. To remove the VIP2 Keypad serial numbers, log on at the front panel and enter

commands 811 and 812.

b. To remove the MSR serial number, enter commands 821 and 822.

c. To remove SI-1 serial numbers, enter 831 and 832 at Entry 1 and Entry 2, respectively.

5. Shut off power.

6. Disconnect the old devices from the network.

a. If you are adding two new devices, connect the device at Entry 1 first.

b. Plug in P7 and P8 and apply power. The SE 422 will take several minutes to read the

serial number. The LED on SI-1 board and the S-NET RX STATUS LED on the SE 422

board will start flashing normally when communications are established. If you have a

device at Entry 2, shut off power, connect the device there, and apply power.

Database Setup from the Terminal

To setup the SE 422 database using a terminal, proceed as follows:

1. Log on, and use the ENTRY command for Entry 1.

2. Assign VIP2 Keypad at Entry 1 to address 13, assign an SI/SE 28XX at Entry 1 to address

15, and assign an MSR at Entry 1 to address 17.

3. Repeat the process for Entry 2, that is, assign a VIP2 at Entry 2 to address 14, assign an SI/

SE 28XX at Entry 2 to address 16, and assign an MSR at Entry 2 to address 18.

4. Shut off power.

5. Disconnect P7 and P8, and change the devices. Leave P7 and P8 unplugged for the next

step.

6. Apply power to the SE 422, log in, and use the SERIAL command to set the serial number

of any device you are replacing to 0 (type 0 and press Enter), or if you know the serial number

(s) of the devices (s) you have connected, enter them.

4-3

7. Shut off power, plug in P7 and P8, and apply power. If you have entered the serial numbers

correctly, the SE 422 should communicate with the devices immediately. If the SE 422 has

to read the serial numbers, the process will take several minutes.

8. If you are letting the SE 422 read the serial numbers of the same type of device at each entry,

and want to make sure that the device at Entry 1 is assigned to the address reserved for Entry

1, connect it first. Then shut off power, connect the device at Entry 2, and apply power.

Note

Refer to the SE 422 manuals for additional information about the database setup procedure.

ENTERING THE SE 1050 COMMAND KEYS

Adding to or removing command keys from the SE 422 database is similar to adding or removing

magnetic stripe cards as described in the SE 422 ACU manuals. Note that each command key

has its eight-digit number imprinted on the key.

You can load command keys using the following methods:

A. You can load the keys individually at the front panel by entering command 32 followed by

entering the eight-digit key number for privileged keys or command 33 for nonprivileged keys.

B. You can also add nonpriviledged keyholders by entering command 841 (Entry 1) or 842

(Entry 2) and presenting the keys individually to the SE 28XX Sensors.

C. You can add keys by entering the Group Command (GR), followed by presenting the keys

to a sensor.

B. You can add keys by entering the key command. Then enter the key codes of the key at the

terminal keyboard.

Removing command keys requires that you enter the command 42 followed by entering the

eight-digit key number for privileged keys and command 43 followed by the eight-digit key

number for nonprivileged keys at the front panel.

Once you have finished entering key codes, check to see that they work. When you present a

command key at an entry that has an SE 28XX Sensor only, the SE 422 should grant access and

unlock the entry for about 10 seconds, or until you open it. The lock will then relock. If you open

the entry, it will be locked when it closes. Make sure the entry switch wiring is correct. The SE

422 will not let sensors read keys when it senses the entry is open.

If an SE 28XX sensor and an MSR are at an entry point, someone wishing to enter can use either

their magnetic strip card or their command key. In either instance, the light on the MSR will indicate

access granted by changing from red to green for 10 seconds or will indicate access denied by

going out for 10 seconds.


4-4

SI-1

If an SE 28XX Sensor is used with a VIP2 Keypad, operation is similar to that of an MSR with a

VIP2 Keypad. The top and middle lights on the keypad will normally be on, indicating that you will

need to present your command key and enter your PIN number, one after the other.

Note

The order in presenting your command key and PIN number doesn�t matter, but the SE 422 does

impose a time limits. You have 10 seconds to enter you PIN after you present your command key.

If you take too long or enter a PIN that the SE 422 does not recognize, you will have to wait about

10 seconds before you can try again.

When the SE 422 recognizes your PIN, the middle light will go out. When the SE 422 recognizes

your key, the top light will go out. Then the bottom light comes on, indicating that the SE 422

granted access and that the entry is unlocked.

INSTALLATION CHECKLIST

o Open the box containing the SE 422 proximity reader hardware.

o Identify all components and verify that no components are damaged.

o Install the SI-1.

o Install the SE 28XX.

o Pull coaxial angle cable between the SI-1 and SE 28XX.

o Terminate and connect the cable.

o Pull the device network data and power cable between the SI-1 and the SE 422, and any other

devices that may be on the network.

o Connect shields at both ends of the cable (s). Connect the wires (see Figure 1-1).

o If the system power supply is not an SE Power Inserter (PI), replace it with a PI.

o Perform the SE 422 setup procedure.

o Group Load one or more SE 1050 Command Keys into the SE 422 and verify that the SE

28XX reads them at each door.

DIAGNOSTIC CHECKS

If the SE 422 does not function properly, check for the following problems:

o The command key is the wrong type (that is, SE 1030 or SE 1040).

o The SE 422 does not recognize the key code (key not in memory).

o The building is armed and the key is not privileged (wrong access code).

4-5

Section 4: SE 422 SetupSI-1

o Incorrect SW2 setting for the devices connected, or incorrect serial numbers for those

devices recorded in the SE 422 database. Be sure to follow the setup procedures carefully,

and check the LED on the SI-1 for indication of being powered up and online. The indicator

on each MSR should normally be red. The middle, or middle and top LED on VIP2 keypads

should be on.

o Inadequate voltage at the SI-1: Pins 1 and 4 of connectors J2 or J3 on the SI-1 should have

at least 17 Vdc between them at all times. You may need to monitor the voltage over time

to catch short term fluctuations. The sensor and the SI-1 have LEDs that will be dim or out

if the supply voltage is low. The possible causes of low supply voltage include the following:

o Low AC line voltage.

o Operation from partially discharged standby batteries.

o Defective PI or other power supply.

o Bad connections.

o Wires too small for the current and distance between the SE 422 (or PI) and the SI-1.

o System grounding: SI-1s and SE 422s must be reliably earth grounded for safety, and for

transient and lighting protection.

o Reliable communications on an EIA-485 network also requires that signal ground voltage at

an SI-1 and at the SE 422 be fairly close. Problems can arise if the SI-1 and SE 422 are earth

grounded to different grounding electrodes in different and distant buildings.

o Conduit joints loosen, separated or corroded, or power wiring defects energize parts of the

conduit system.

o The DC common wire between and SI-1 and SE 422 is so long or small that return current

in it produces too much voltage drop from end to end.

o A simple test for signal-ground offset in an operating system is to measure the AC and DC

voltage between pin 3 (PWR-) of P7 or P8 and pin 6 (GND) of P7 or P8. Using a VOM, This

voltage offset must never be more than 2 volts.

o Noise: Data wiring is vulnerable to crosstalk between adjacent wires and pickup of electrical

noise. Either can cause unreliable operation. Even wiring that meets ordinary standards for

good practice can pick up spurious signals from obscure sources. Generally, the symptoms

will point to a particular part of the system. If only on SE 28XX sensor consistently

malfunctions, check that the sensor or the coax cable to its sensor interface module. If two

sensors connected to the SE 422 fail, check the SE 422 or the wiring between it and the SI-

1.

o Intermittent or random communication problems, however, may be much more difficult to

track down. First check to see that the wiring meets the guidelines outlined in this manual,

then isolate the problem. If you suspect it may be crosstalk between the wires in a particular


4-6

SI-1

conduit run, connect a temporary by pass for the suspected circuit outside the conduit. If you

suspect a wire is picking up fields generated by nearby equipment, try rerouting or shielding

it. Be sure all shields and conduit are grounded properly.

Note

If you suspect outside signals are being picked up by the sensor itself and interfering with valid key

reads, contact with WSE Customer Service for additional guidance.

LED Diagnostic Checks

The SE 28XX Sensor has one LED in the middle of the PCB. When the sensor is used with the

SI-1, the sensors LED should not be blinking, but it should be on steady. If the LED is out, voltage

at the sensor is probably inadequate for operation. Check the power input to the SI-1 sensor

interface.

The SI-1 has one (normally blinking) LED in the middle of the PCB. If it is out, voltage to the PCB

is probably inadequate. However, the SI-1 LED indicates much more than power to the board.

Table 4-2 lists some of the meanings of the blinking SI-1 LED. Because of interrupts coming from

the SE 422, the LED blinks are not always entirely regular; watch through several cycles before

drawing any conclusions.

Table 4-2. SI-1 LED Troubleshooting

LED State Indication

One blink followed by

two blinks.

The SI-1 is communicating normally with both sensors and

the SE 422. No key is being presented or read.

Two Blinks. The SE 422 is functioning, but the SI-1 has a problem

reading its sensor.

One blink followed by

two blinks followed by

three blinks.

The SI-1 is communicating with the SE 422 and is sensing

the presence of a key and is attempting to read that key.

On steady. The SI-1 microprocessor is functioning, but the SI-1 is not

communicating with the SE 422. Either the SI-1 is not

connected, it is not responding, or the wiring is faulty.

Failure to configure the SE 422 to recognize an SI-1/SE28XX is another possiblility. The SI-1 will not try to

communicate with its sensor unless the SE 422 recognizes

it. (See Table 4-l for setting the configuration dip switches,

SW2.)
