Some Metasys system hardware may be used in both power-limited and non-power-limited circuits. These circuits must be segregated during system design to comply with the appropriate codes. The wiring system must be designed in groups, with each Field Terminal Board (TBF) bay being chosen to house all power-limited or non-power-limited field wiring. See the Wiring Segregation section in this document for details on wiring segregation requirements for Metasys system extended architecture products.

In order to meet the requirements of Underwriters Laboratories, Inc.® (UL) under UL 864 UUKL Smoke Control, some of the Metasys system field wiring must be protected by installing transzorbs or Metal Oxide Varistors (MOVs). This protection is only required if the field wiring to the monitored and controlled equipment leaves the room where the controller is installed. A more detailed description of the requirements including tables showing which point types require protection may be found in the Metasys Field Interface Point Types section in this document.

Isolate the Smoke Control System on a dedicated backbone. If you are using an existing backbone, consult the customer’s Information Technology (IT) department to physically isolate the backbone.

ReferencesWhen designing your smoke control system, you must read and become familiar with the following documents, codes, and standards:

• NFPA 92A Recommended Practice for Smoke Control Systems

• American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) publication entitled Design of Smoke Control Systems for Buildings

• NFPA 70 National Electrical Code

Smoke Control RequirementsThis section contains the Metasys system configuration requirements for a UL 864 UUKL Listed smoke control system. These must be followed in order to comply with the UL Listing. Assume any reference to UL Listing to mean UL 864 UUKL Listing, unless otherwise stated.

The Johnson Controls Smoke Control Listing described in this document is valid only with Metasys system extended architecture components Listed for smoke control.

Agency RequirementsThe National Fire Protection Association (NFPA) and UL have published documents, which include provisions for the control of smoke. These documents are:

• NFPA 92A Recommended Practice for Smoke Control Systems

• NFPA 90A Air Conditioning Systems

• UL 864 Control Units for Fire Protective Signaling Systems

• UL 555S Standard for Leakage Rated Dampers for Use in Smoke Control Systems

• NFPA 72 National Fire Alarm Code

• NFPA 70 National Electrical Code

• NFPA 101 Life Safety Code

• In Canada, refer to the following documents:

• ULC/ORD-C539 Fire Alarm Devices, Single and Multiple Station, Mechanically Operated

• ULC/ORD-C2043 Fire Test for Smoke and Visible Heat Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces

Current versions of NFPA documents can be purchased by calling the National Fire Protection Association at 1-800-344-3555. Current versions of UL documents can be purchased by calling UL at 1-888-853-3503.

As with other types of systems designed and installed to protect life and property, the responsibility for approving equipment, installations, and procedures lies with the local Authority Having Jurisdiction (AHJ). The phrase Authority Having Jurisdiction refers to the agency or individual responsible for approving equipment, an installation, or a procedure and giving permission to occupy a building.


In most municipalities, that responsibility lies with the fire chief, fire marshal, electrical inspector, or others having statutory authority. Become familiar with the building codes of your community as their requirements may differ from those of the NFPA.

Other entities, such as an insurance carrier or hospital accreditation organization, may have influence and/or right of approval of the configuration of the smoke control system.

Smoke Control System Requirements per UL 864 UUKLThe following requirements must be followed in configuring and assembling a Metasys Network in order to comply with the UL 864 UUKL Smoke Control Listing:

• All field wiring must be done in compliance with the Metasys System Extended Architecture Smoke Control Wiring Technical Bulletin (LIT-1201753).

• The Ethernet card used for connecting the NU-NCM350-8 to the N1 Local Area Network (LAN) must be the NU-ETH101-0 (available directly from Johnson Controls).

• A UL 864 UUKL Listed Firefighters’ Smoke Control Station (FSCS) must be used to provide manual control of smoke control systems. The UL Listed annunciator panel, made by Automation Displays, Inc., is the UL Listed FSCS for the Johnson Controls Smoke Control System..

• Each Binary Output (BO) object, used for pressurization and exhaust control outputs, must be configured with positive feedback which monitors the associated controlled equipment status. Typically, smoke control dampers provide a pair of feedback binary inputs for the two damper end switches. For fans used for smoke control, provide positive indication of airflow with either a flow switch or static pressure sensor to determine the On/Off status of the fan.

• Positive indication on the FSCS of the operation of all smoke control equipment must be provided, such as both the open and the closed damper end switches for each smoke damper, airflow measurement, or static pressure measurement for each smoke control fan.

• When any smoke control equipment does not respond to automatic or manual commands, this trouble condition must be visibly and audibly indicated on the FSCS.

• The FSCS controls the Sonalert logic for all smoke control systems; no extra application is necessary.

• The Weekly Testing of Dedicated Stairwell Pressurization Fans - Metasys System Extended Architecture Application Note (LIT-1201739) application must be used on all dedicated smoke control systems.


• The status of all smoke control systems must be displayed simultaneously on the FSCS. Once a system has been accessed, you must display on the FSCS all control points (fans, dampers, and so forth) in that system simultaneously.

• Duct smoke detectors are often located in the return duct of a Heating, Ventilating, and Air Conditioning (HVAC) fan and connected to stop the fan when smoke is detected, which is in compliance with NFPA 90A. However, if the fan is used for smoke control, and the smoke control strategy is such that the return duct is configured to exhaust smoke from the building during the smoke control system operation, then the duct detector should be prevented from stopping the fan, once the smoke control system has been activated.

• Automatic activation of any smoke control sequence of operation must have priority over any automatic environmental control strategy and over any non-smoke control manual commands. When an automatic smoke control sequence is initiated, the system design must bypass the following operational overrides:

- High and Low Temperature Protection Devices (i.e., A-11 and A-25 Series Temperature Protection Devices)

- Return and Exhaust Air Duct Smoke Detectors

• Manual activation or deactivation of any predefined smoke control strategy from the manual override station must have priority over any automatic smoke or environmental sequence of operation. The FSCS serves as the manual override station.

• To protect against signal transients, use an American Power Conversion (APC®) ProtectNet® model PNET1 Ethernet/token ring port surge protector on each end of the copper lines with RJ45 connectors. Contact American Power Conversion at 1-800-800-4272. A transient surge suppressor is not needed if the line stays in the same room as the two devices it connects and is less than 20 feet (6 meters) long.

• Use a Tripp Lite® ISOBAR®8ULTRA power line surge protector or a Tripp Lite IBAR®12ULTRA power line surge protector on all 110-120 VAC power sources. Use one of these two surge protectors on all devices in the smoke control system that use AC power (including AC to DC adapters). Contact Tripp Lite at www.tripplite.com.

• After an alarm is received and acted upon automatically by the smoke control system, additional alarms must not cause the smoke control system to take automatic secondary actions. However, the system will execute any manual commands from the FSCS.

• All communication links between buildings must be fiber-optic cable or copper cable buried in a conduit that is separate from power wiring.


• Response time for individual smoke control components to achieve their desired operational state should not exceed the following time periods: 60 seconds for fan operation at the desired state plus 10 seconds to annunciate; 75 seconds for completion of damper travel plus 10 seconds to annunciate. In the case of fan start after damper close, these times are additive. If the damper must be closed before the fan starts, the total response time could be up to 135 seconds for operation, 75 seconds for damper to close plus 60 seconds for fan to start. Time to annunciate would be added to this time. (Control system response is the time from automatic detection of a smoke condition to the issuance of an appropriate command to the equipment.)

• In smoke control applications, you must reserve Priority 2 commands for BOs used for smoke control functions, such as fan and damper control. All other non-smoke control logic should use lower command priorities.

• To design a smoke control system that sends commands across the N1 LAN, you must use the NAE/NIE to interface all input and output smoke control points.

DX-9100 Controller Application RequirementsThe following requirements apply when using hardwired DX-9100 controller applications:

• A DX base with transient protection devices (Metal Oxide Varistors (MOVs) must be used. The Johnson Controls product code number for the DX base with MOVs is DX9100-8990F.

• All alarm input Digital Inputs (DIs) must be monitored and report critical alarms at the FSCS when they close (turn On), such as a fire alarm control panel smoke detector alarm point.

• You must monitor the fuse on the DI circuit of each DX-9100 controller when the DI is used for smoke control. To do this, connect a jumper wire across one spare DI, so that it will always indicate an On condition. If the fuse fails, this point will go off, indicating a fuse failure. Map this point to the FSCS directly connected to the NAE as a critical alarm with a normal state of Closed (On).

• Any time that you use Analog Outputs (AOs) in your configuration for smoke control, you must monitor the fuse on the AO. To do this, set one AO for voltage and define an Analog Input (AI) for voltage. Connect Analog Constants (ACs) set for 50.0 to the AO that is ranged for 0–100. This gives the AO a 50 percent signal or a 5 volt output. This output is hardwired to the AI defined for voltage with a range of 0–100 and a low limit of 20. If the AO fuse blows, the voltage will go to 0 and the AI will go into low alarm. This alarm must be monitored as a critical alarm.

• Any DX-9100 controller used in a smoke application must have a Metasys system poll priority of 1 or 2.


• All fans controlled by the DX-9100 controller must have an airflow status switch. Any mismatch of command and HVAC equipment controller status of the fans must report a critical alarm at the FSCS.

FSCS RequirementsRequirements of an FSCS include the following. The FSCS must:

• have full monitoring and manual control capability over all smoke control systems and equipment

• have the capability to override (partially or in full) any operation in progress, including programmed actions, non-smoke control manual overrides, and non-smoke control bypasses

• have highest priority over all smoke control systems and equipment

• have a building diagram clearly indicating the type and location of all smoke control equipment

• have indication of the actual status (not the command status) of systems and equipment used for smoke control. This includes both the full open status and the full closed status of each smoke control damper, the status of each fan used for smoke control.

• activate an audible signal if the operation proof sensor (binary feedback point) failed to provide positive feedback that its command was executed within the allowed response time

• have its alarm horn turned on by all hardware supervision alarms, such as binary feedback alarms on fans and dampers, as well as the system troublepoints

• be the only FSCS on a Metasys network used for smoke control applications, unless multiple FSCSs are approved by the AHJ

Note: Use the UL listed annunciator panel as your FSCS. The panel is available from:

Automation Displays, Inc. (ADI)3533 N. White AvenueEau Claire, WI 54703(715) 834-9595

A custom annunciator-type FSCS can be connected to any UL 864 UUKL Listed NAE55 in the network.


Smoke Control Restrictions per UL 864 UUKL Smoke control system restrictions per UL 864 UUKL follow. Do not use:

• the fire alarm system manual pull stations to initiate automatic smoke control sequences. Only automatic alarm initiating devices such as smoke, heat, or flame detectors should be used.

• a duct-type smoke detector to initiate a smoke control strategy except as detailed in the Smoke Control Strategies section of Metasys System Extended Architecture Smoke Control System Technical Bulletin (LIT-1201684).

• the web browser user interface to provide smoke control. The UL listing does not include the Web browser user interface for smoke control and as an FSCS.

• any Ethernet communication equipment that is not UL listed. All NAE networks are Ethernet-based. Refer to the Metasys System Extended Architecture Smoke Control System Technical Bulletin (LIT-1201684) for more information.

• NIE to perform smoke control sequence operation

• any equipment that is not UL Listed

DX-9100 Controller ApplicationsThe following are smoke control system restrictions per UL 864 UUKL for the DX-9100 controller applications:

• The buttons on the face of the DX-9100 controller cannot be used to override smoke control points.

• Any DX-9100 controller used for smoke control must be locked in an enclosure (for example, EN-EWC25-0) to prevent unauthorized access.

N1 Network ConnectionsFor information beyond what is in this section, refer to:

• Metasys System Extended Architecture Smoke Control System Technical Bulletin (LIT-1201684)

• the manufacturer’s information packaged with the devices

Follow these additional guidelines when installing the equipment in this chapter:

• Use an American Power Conversion (APC) ProtectNet model PNET1 Ethernet/token ring port surge protector for LAN equipment on all RJ45 lines to protect against signal transients. Contact American Power Conversion at 1-800-800-4272.


• Use a Tripp Lite ISOBAR8ULTRA power line surge protector or a Tripp Lite ISOBARBAR12ULTRA power line surge protector on all 110-120 VAC power sources. Use one of these two surge protectors on all devices in the smoke control system that use AC power. Contact Tripp Lite at www.tripplite.com.

Type 3, Modules Rated as Both Power-Limited and Non-power-Limited (Application Specific)

For Type 3 modules (power-limited/non-power-limited), it is up to the system designer to ensure that modules are segregated, based on application.

In base frame applications, wiring must be grouped by bays. Each bay in a base frame must be dedicated as either power-limited or non-power-limited. Base frames are shipped with a label on each bay stating Power-Limited Field Terminal.

When configuring a base frame and using a bay for non-power-limited field connections, you must use a permanent black marking pen to cover the wording on the label. The only bays that should display this label must be totally dedicated to power-limited field wiring. Bays that do not display this label must be totally dedicated to non-power-limited field wiring. In no case should power-limited field wiring be mixed with non-power-limited field wiring.

The XTM/XPx-xxx product line has labels displaying whether it is power-limited or non-power-limited. For the XPx modules shown in Figure 4, if the field wiring is non-power-limited, the power-limited label must be covered with a black permanent marking pen as explained above. For a specific module, only one type of wiring may be used per side on the module.Table 4: Power-Limited and Non-Power-Limited ModulesModule TypeXPE-4xx-5XPL-4xx-5XPM-4xx-5

Input (also with Relay): Connect these contacts to a UL Listed Class II or Class III source of supply to be considered a power-limited module. If not connected as described above, follow the guidelines defined in the Wiring Segregation section.


RepeaterInstall the repeater inside a UL Listed enclosure (see Enclosures). The repeater provides isolation on the N2 end of a smoke control system. Input and output wiring is supervised and power-limited. The repeater has non-power-limited wiring for the input power source. Refer to the Metasys System Extended Architecture Smoke Control System Technical Bulletin (LIT-1201684) and the N2 Communications Bus Technical Bulletin (LIT-636018).

Use wire with the following specifications when wiring power to the repeater:

• 600 Volts, 20 Amperes AC Insulated 3-conductor cable

• 12 to 18 AWG (without terminal lugs); 14 to 18 AWG (with terminal lugs)

• Less than 32 feet (10 meters) length

EnclosuresMount NAE55, NIE, NCM350 controllers, DX-9100 controllers, switches, routers and all other equipment in the smoke control network in a UL Listed enclosure. See the installation information packaged with each product.

Power EntryBring input power (120 VAC) into the enclosure in the corner nearest its termination location. For example, the EN-EWC10-45 Series enclosure has a conduit entry area molded into the cover.

Bring power into only these locations based on where the power box is located.

Wiring SegregationThe Air Handling Unit (AHU), Variable Air Volume (VAV) Controller, Unitary (UNT) Controller, and the Variable Air Volume Modular Assembly (VMA), contain only power-limited field connections; therefore, they are not discussed here.

Segregate power-limited/non-power-limited wiring. N1 and N2 communication lines are considered power-limited. Route these communication lines only with other power-limited wiring.

Handle the XTM/XPx product line in a similar way (Figure 11). There are no wire trays; maintain segregation of cables using wire ties. For more wiring information on the XTM/XPx product line, see XTM-105 Extension Module, XPx-xxx Expansion Modules Technical Bulletin (LIT-6364200).

Input/Output (IO) Wiring Transient Protection Requirements

UL 864 UUKL Smoke Control Listing requires that any field I/O wire, from monitored or to controlled equipment, respectively, that leaves the room in which the controller is mounted, must be able to withstand signal line transient of 2400 volts and energy levels not less than 0.03 joule or greater than 1.2 joules. To meet this requirement, some of the Metasys system field wiring must be protected by either transzorbs or MOVs. If the hardware you are using is not mentioned in the following sections, no transient protection is required.

When installing the transient protectors (MOVs, transzorbs), care must be taken when installing a protector in close proximity to other protectors. Before installing the protective device in the terminal block, twist it together with the field lead and insert it into the terminal block as one wire. Twist the wire tightly around the transient protection device a minimum of two turns before inserting it into the terminal block.

AP-VMAKeep all field wiring, with the exception of the N2, in the same room as the controllers.

DX-9100 ProductsWhen using the DX-9100 product line for Listed Smoke Control, there are only two I/O restrictions.

1. Use the DX-9100-xxxxF base. (This base has the transient protection already installed.)

2. When using the XP-9102, if the field wiring leaves the room in which the XP-9102 is installed, install the protection shown in Table 6. (The MOV must be a Johnson Controls Code No. SMOKE-MOVKIT.)

For further information on the DX-9100 product line, refer to the DX-9100 Applications sections in the Metasys System Extended Architecture Smoke Control System Technical Bulletin (LIT-1201684).

NAE55No transient protection is required on any of the I/O terminals of the NAE55. Use only the UL 864 UUKL Listed NAE for smoke control.

NIENo transient protection is required on any of the I/O terminals of the NIE. Use only the UL 864 UUKL Listed NIE inside a smoke control system.

NCM350-8No transient protection is required on any of the I/O terminals of the NCM350-8. Use only the -8 version of the NU-NCM350 for smoke control.

NU-RPT101-0Install tranzorbs on the NU-RPT101-0 on both terminal blocks TB1 and TB2. The tranzorbs must be from tranzorb kit SMOKE-TRNKIT-1, which must be ordered separately.

Install the tranzorbs to terminal blocks TB1 and TB2 using the following procedure:

1. Strip the N2 bus wiring to 0.5 inches.

2. Twist the N2 bus wiring together with the wires from the tranzorbs (SMOKE-TRNKIT-1).

3. Attach the twisted wires to the terminals. Attach the single wire side of the SMOKE-TRNKIT-1 to the COM terminal and the multiple wire side to the D and D- terminals.

AHU, UNT, VAV ProductsInstall MOVs to the AHU, UNT, and VAV products in Table 7. Only terminals in use, and I/O wiring leaving a room where a controller is installed, need transient protection. The MOV must be a Johnson Controls Code No. SMOKE-MOVKIT-0 for terminal block versions. The MOV must be a Johnson Controls Code No. AS-MOVKIT-0 for faston versions.Table 7: Transient Protection for AHU, UNT, and VAV Products I/O Function Module Protection NeededAnalog Inputs (AIs) AHU, VAV, UNT: Install an MOV from each AI to AIcom.Binary Inputs (BIs) AHU, VAV, Mod UNT: Install an MOV from each BI to BIcom.
