Cabinet Dimens ions and Weight

Each DCX 250 cabinet (if it has a cabinet) is approximately 8.1 × 8.1 × 3.5 in. and weighs 8.5 lbs.

Power Requirem ents

CautionIf the DCX 250 is in its own cabinet, it should receive power from its own independent, unswitched circuit.

The DCX 250 operates on 24 VAC +/–20% 50 or 60 Hz (for smoke con-trol applications, 24 VAC +10/–15%, 60 Hz). The DCX 250 consumes up to 18 VA of power.

Cable Limitations

The maximum cable length for Infinet is 4,000 ft at 19,200 baud (up to 32 Infinet controllers). You can extend Infinet beyond 4,000 ft or put more than 32 Infinet controllers on less than 4,000 ft by using the In-fiLink 200 amplification module.

Cables that form Infinet are 24-gauge, single-twisted-pair, tinned, shielded copper wire. Use the following cables1 or their equivalents:

NoteYou must use shielded cables for Infinet to ensure compliance with the Class A FCC limits and to communicate reliably.

• Brand Rex # H 9002 (single-pair)

• Anixter # 9J2401021 (single-pair plenum cable)

The cable should have a nominal impedance of 100 Ohms and anominal velocity of propagation of 78%.

1. You can also use any cables you may already have in place for ACNET or LBUS.

www.PDF-Zoo.com



Capacitance of Infinet cable should be nominal, below 12.5 pF/ft be-tween conductors and below 22 pF/ft between the conductor connected to ground and the next conductor.

Lightnin g Protec tion

WarningWhen running cables between buildings you must install lightning arresters for Infinet to prevent electromagnetic disturbances.

Use lightning arresters at each point where Infinet cable enters or exits a building. Use the following arrester:

Two pair gas tube arrester, Andover Controls # 01-2100-299.

Bui lding G round Requireme nts

WarningBe sure that all Infinity hardware products from Andover Controls Corporation are grounded to true earth ground. This kind of ground protects the equipment from voltage transients and other power surges in the area. We cannot guarantee that the controller system will operate as documented unless you properly ground all controllers.

WarningBe sure to have your grounds inspected before you begin the installation process to be sure your municipality follows the National Electrical Code. Many municipalities do not and may have substandard electrical grounds.

An example of a substandard ground is a galvanized steel cold water pipe. As the pipe corrodes, it does not act as a true ground. The corro-sion acts as an insulator, raising the potential of the pipe with respect to the ground.

www.PDF-Zoo.com



When lightning strikes in the area of the installation, it drastically changes the potential of the earth. Since properly grounded Andover Controls units respond to changes in potential more rapidly than poorly grounded electrical systems, a poorly grounded building tries to reach ground through the Andover Controls system. The surge of current can destroy electronic components on the controller board.

Surges of much lower potential than lightning also impact the reliability of Andover Controls equipment.

Inspec ting the Ground

You can check your ground as follows:

1. Check your ground by first inspecting the building power distribution panel for earth ground termination. If the ground termination is any of the following, it is not adequate and must be corrected:

• Does not exist.

• Is connected to a corroded or galvanized pipe.

• Is connected using a small gauge wire (less than 14 AWG).

2. Be sure your Andover Controls cabinet is connected to the ground with a copper conductor that terminates at the distribution panel.

Environm ental Requi rements

The DCX 250 operates in rooms with temperatures ranging from 40 to 104°F and with humidity of between 30 and 85%, noncondensing.

The controller is designed to withstand the dust normally present in an equipment room, without any additional enclosures or filtering.

The cabinet that Andover Controls Corporation encloses the DCX 250 in is an Underwriter Laboratories listed enclosure.

www.PDF-Zoo.com



Laying Out the Site Setup

You may want to draw a map of where you plan to put each controller and store it in a notebook.

Find the tag attached to each controller that gives the number of the con-troller. Before you remove any tags, be sure the tag has all of the following information on it:

• Model number.

• Serial number.

• Location of the DCX 250 controller.

• Communications port the Infinet connects to on the Infinity CX 9000. (The DCX 250 installed inside the Infinity CX 9000 cabinet is automatically on COMM2.)

Figure 1 shows what the tag looks like.

Then collect the tags. You will need to know where your controllers are located when you later assign a name to each controller and each input and output.

Connecting the AC Powe r Cableto the Po wer Supply

If you ordered the DCX 250 in its own cabinet (to be placed on the In-finet outside the Infinity CX 9000), the DCX 250 has its own power supply. So you need to connect the AC power cable.

WarningBe sure the AC power cable is not connected to an electrical power source while you are wiring the controller, or you could receive an electrical shock that is life-threatening.

NoteIf the installation requires the secondary of the 24 V transformer to be grounded, always connect the "neutral" to ground and only ground it at the transformer.

To connect the AC power cable, proceed as follows:

1. Lift off the front display panel on the DCX 250.

Figure 4 shows the inside of the DCX 250 controller.

Notice the board now directly in front of you is the power supply. Look to the upper left corner for the AC power connection. You must wire the AC power to the three screws on the upper left side of the power supply.

2. Thread the AC power cable through the cutout in the top of the DCX 250 cabinet.

CautionBe sure to connect all three wires, HOT, NEUTRAL, and GROUND. Otherwise, the controller could malfunction.

www.PDF-Zoo.com



3. The three screws are labeled GND NEUT HOT. The three wires at the end of your AC cable are black, white, and green.

4. Place the green wire under the metal plate behind the left screw, labeled GND.

Poweri ng Up/Adjusting the ControllerBoth the DCX 250 inside the Infinity CX 9000 and the DCX 250 in its own cabinet have a battery you need to connect.

Connecting the Battery

Lift off the front display panel on the DCX 250. Inside, on the back of

the display screen, find the AA battery on the upper left of the board.

Figure 8 shows the location of the battery. Remove the plastic tab below the clip on the battery to activate the battery.

The battery is a 850 mA-hr 3.6 V primary lithium battery that maintains RAM when AC power goes out.

Powerin g Up

The DCX 250 inside the Infinity CX 9000 runs off the power supply of the Infinity CX and begins operating when you connect AC power to the Infinity CX 9000.

For the DCX 250 in its own cabinet, you must check to be sure the fol-lowing are correct:

1. Be sure the AC power is wired properly. Check to be sure all three wires have been connected.

2. Be sure the controller has a true earth ground.

3. Be sure you have used the proper cables and correct lengths.

4. Be sure the battery is connected.

If you have completed all appropriate sections in this manual and in-stalled all Infinet controllers, you are now ready to power up the controller.
