A UL 864 UUKL Smoke Control Compliance Survey form is followed by tables listing the requirements for UL 864 UUKL Listing compliance. The purpose of the enclosed UL 864 UUKL Smoke Control Compliance Survey is to provide a record of those elements of NFPA (National Fire Protection Association) 92A and UUKL, which are being provided by Johnson Controls and not being provided by Johnson Controls. UUKL is an identifier created by UL to identify those products Listed under UL 864 as Smoke Control Equipment. It should be recognized that the UUKL Listing is based on a supplement to UL 864, rather than part of the formal standard. That supplement is based on NFPA 92A, which is a Recommended Practice rather than a Code or Standard. Products covered by this Listing are intended to be installed in conjunction with Heating, Ventilating, and Air Conditioning (HVAC) equipment to form a system for controlling the flow of smoke in a building during a fire condition in accordance with NFPA Recommended Practice 92A. A Recommended Practice, as defined by NFPA, uses the word “should” to indicate recommendations, as opposed to a Standard or Code, which uses the word “shall” to indicate requirements. Since the UUKL Listing is based on a Recommended Practice, which is less stringent and less binding than an NFPA Standard, a considerable amount of latitude is granted to the designer of the smoke control system. For example, the designer may choose to implement some of the elements identified in the Smoke Control Compliance Survey, such as positive damper position annunciation from two end switches, while choosing not to provide other elements, such as the FSCS (Fire Fighter’s Smoke Control Station) annunciator. This is acceptable as long as there is agreement with the local Authority Having Jurisdiction (AHJ) regarding the configuration. As a result of the latitude granted the designer and because of the variation among job specifications, it is important that we document the system elements that are being provided, along with those that are not being provided. The Smoke Control Compliance Survey can be used to provide that documentation. Smoke Control—Smoke Control UL 864 UUKL Compliance Checklist 3 In the case where a project specification dictates compliance with the UUKL Listing, but contains elements of the system design which conflict with the Listing or are omitted, the completed UL 864 UUKL Smoke Control Compliance Survey can be given to the designer and/or AHJ to obtain recognition and agreement on the extent of Listing compliance. This should occur prior to bid and/or proposal. Once agreement is reached with the AHJ, designer, and customer, the signed or initialed Smoke Control Compliance Checklist must become a permanent part of the project file. Literature 4 If you are bidding, engineering, installing, or commissioning a Metasys System requiring UUKL Smoke Control Listing compliance, follow the guidelines and procedures outlined in the latest issue of the Metasys technical bulletins. Refer to the Smoke Control Technical Bulletin (LIT-636330) and the Smoke Control section in the Metasys Network Technical Manual (FAN 636) for complete information. In addition, read and become familiar with the applicable building codes and standards documents listed in the Smoke Control Technical Bulletin (LIT-636330).

Mark Yes/No for compliance and initial each item that was verified. Table 1: General UUKL Requirements Requirement Communication links between buildings are fiber optic cable or copper cable buried in a conduit separate from power wiring. Each binary output object used for pressurization and exhaust control outputs is configured with its own feedback binary input. The feedback binary input monitors the associated controlled equipment status (both open and closed, on and off, etc.). For smoke control dampers, there is a pair of feedback binary inputs for two damper end switches. For fans there is positive indication of air flow and/or on/off status of fan. Manual operations occurring from a non-UUKL Listed OWS (Operator Workstation) isolated from the Listed segment of Metasys do not have priority over automatic smoke control sequences by normal system operators or those initiated manually from the manual override station. The Weekly Testing of Dedicated Stairwell Pressurization Fans application is used on all dedicated smoke control systems. BOs have Priority 2 commands and all other non-smoke control logic use lower command priorities. Automatic activation of any smoke control sequence of operation has priority over any non-smoke control manual commands and any automatic environmental control strategy, when an auto smoke control sequence is initiated. High and low temperature protection devices and return and exhaust air-duct smoke detectors are bypassed. Response time for individual smoke control fan to commanded state is no more than 60 seconds. Response time for individual smoke control dampers to commanded state is no more than 75 seconds. Fire alarm system manual pull stations do not initiate automatic smoke control sequences. Smoke detectors are used to initiate a smoke control strategy only as detailed in the Smoke Control Technical Bulletin (LIT-636330). All Application Specific Controls (ASCs) that monitor or control smoke control equipment are UUKL Listed. The Operator Terminal on a Metasys Network is not used for smoke control. Any NCM100s are upgraded to NCM200/201s with transient protection where required. The system is configured to record all smoke control system alarm and trouble messages on the PRN-3/-4 printer. Electrical disconnects, overloads, duct static pressure limits, and supply air duct smoke detectors are not overridden by manual or automatic smoke control strategies. Network Terminal on Metasys Network are used on smoke control systems, but are not used for smoke control functions. A UUKL Listed active hub separates the N1 into UUKL and non-UUKL segments. No smoke control or related monitoring is associated with the non-UUKL segment. 6 Smoke Control—Smoke Control UL 864 UUKL Compliance Checklist Y/N NA Person Verifying Fire Fighter’s Smoke Control Station (FSCS) UUKL Requirements Table 2 lists general requirements for UL 864 UUKL Listing compliance for FSCSs where required. Mark Yes/No for compliance and initial each item that was verified. Table 2: FSCS UUKL Requirements Requirement Y/N NA Person Verifying FSCS is UUKL Listed and provides manual control of smoke control system, a UUKL Listed annuciator panel is used as FSCS, or a Fire OWS is used as FSCS (see Fire OWS as FSCS UUKL Requirements section ) with AHJ approval. Custom annuciator FSCS is connected to a UUKL Listed NCM300/350-2. FSCS provides positive indication of the operation of all smoke control equipment (both open and closed, on and off, etc.). FSCS provides trouble indication when any smoke control equipment does not respond to automatic or manual commands. The Local Sonalert Logic application is used on FSCS. FSCS indicates alarm conditions from any air duct smoke detector. FSCS simultaneously displays the status of all smoke control systems dampers, fans, etc. FSCS has full monitoring. FSCS has manual control over all smoke control systems. FSCS can override (partially or in full) any operation in progress, including programmed actions, non-smoke control manual overrides, and non-smoke control bypasses. FSCS has highest priority over all smoke control systems. A building diagram or equivalent at FSCS clearly indicating the type and location of all smoke control equipment is refunded. FSCS indicates 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, and the air flow status of every fan. FSCS activates an audible signal if the operation proof sensor (binary feedback point) failed to provide positive feedback that its command was executed. Only one FSCS on Metasys is used for smoke control applications unless approved by the AHJ. The FSCS manual activation or deactivation of any smoke control device has priority over any automatic smoke or environmental sequence of operation. Any return air duct smoke detectors in duct work of each HVAC fan system used for smoke control exhaust or purge only reports an alarm condition to the FSCS or fire alarm annunciator located at the FSCS and does not stop the fan. The FSCS is not a standard (non- UUKL Listed) OWS. All hardware supervision alarms, such as binary feedback alarms on fans and dampers, as well as system alarm points turn on FSCS alarm horn. Annunciation on the FSCS of change of state of smoke control equipment is no more than 90 seconds after reaching commanded state. Smoke Control—Smoke Control UL 864 UUKL Compliance Checklist 7 Fire OWS as FSCS UUKL Requirements Table 3 lists general requirements for UL 864 UUKL Listing compliance for Fire OWSs used as the FSCS. Mark Yes/No for compliance and initial each item that was verified. Refer to Fire Operator Workstation (Fire OWS) Technical Bulletin (LIT-636014) for more details. Table 3: Fire OWS as FSCS UUKL Requirements Requirement If the Fire OWS has been approved by the AHJ as the FSCS, and is used for Metasys operation only, then there is access to Program Manager for maintenance purposes to operators with high level password access to prevent the normal operator from exiting Metasys operation. The Fire OWS cannot prevent an operator from exiting Metasys; so it is the supervisor’s responsibility to ensure this does not occur. If the Fire OWS is used as the FSCS, (approved by the local AHJ), it has graphic presentation of the status of all smoke control systems (dampers, fans, etc.) displayed simultaneously on the FSCS. A watchdog timer (WD-TIMER-FIRE) is located at and connected to the Fire OWS. The ARCNET® card connecting the Fire OWS and the NU-NCM300/350-2/-8 to the N1 LAN is NU-ARC101-0. A PRN-3/-4 printer is connected to the Fire OWS. If the Fire OWS is not being used, a PRN-3/-4 printer is connected directly to at least one UUKL Listed NU-NCM300/350-2/-8 that is running the smoke control algorithm and the NCM is configured as “NC Direct.” 8 Smoke Control—Smoke Control UL 864 UUKL Compliance Checklist Y/N NA Person Verifying DX-9100/9120 Applications UUKL Requirements Table 4 lists general requirements for UL 864 UUKL Listing compliance for DX-9100/9120 applications. Mark Yes/No for compliance and initial each item that was verified. Table 4: DX-9100/9120 Applications UUKL Requirements Requirement Y/N NA Person Verifying The model DX9100-8990F base with premounted MOVs transient protection is used. If the DIs are used for smoke control, the fuse on the Digital Input (DI) circuit of that DX-9100/9120 is monitored by a jumper wire across a DI, mapped to the Fire OWS (or to the required PRN-3/-4 printer directly connected to the NC) as a critical alarm with a normal state of Closed (On). If Analog Outputs (AOs) are used for smoke control, the fuse on the AO circuit of that DX-9100/9120 is monitored by doing the following. They are fused and the fuse is monitored. To do this, set one AO for voltage and define an Analog Input (AI) for voltage. Connect a CO 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 back 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. Each DX-9100/9120 used for smoke control has a Metasys poll priority of 1or 2. All fans controlled by the DX-9100/9120 have an air flow status switch. Any mismatch of command and status of the fans reports a critical alarm at FSCS. An IFC-1010/2020 is connected directly to Metasys via the N2 Bus or the Metasys Intelligent Fire Network (MIFN) to initiate automatic smoke control actions. Dry contacts of a fire alarm control panel are connected directly to a DX-9100/9120 to initiate automatic smoke control actions. If the fire alarm control panel alarms are not displayed on an annunciator at the FSCS, all alarm input DIs are monitored and report critical alarms at the Fire OWS when they close (turn On), such as a fire alarm control panel smoke detector alarm point. The buttons on the face of the DX-9100/9120 are not used to override smoke control points. Any DX-9100/9120 for smoke control is locked in a Listed enclosure, such as the EN-EWC25-0 to prevent unauthorized access. All alarm input DIs are monitored and report critical alarms and Fire OWS when they close (turn On). Any signal circuits connected to the XP9102 do not leave the room in which the XP9102 is mounted unless transient protection is applied as detailed in the Metasys Smoke Control Wiring Technical Bulletin (LIT-6366331). If signal circuits leaves the room, transient protection is applied as detailed in the Metasys Smoke Control Wiring Technical Bulletin (LIT-636331). Smoke Control—Smoke Control UL 864 UUKL Compliance Checklist 9 Smoke Control Wiring UUKL Requirements Table 5 lists general requirements for UL 864 UUKL Listing compliance for Smoke Control Wiring. Mark Yes/No for compliance and initial each item that was verified. Table 5: Smoke Control Wiring UUKL Requirements Requirement If signal circuits leaves the room, transient protection is applied as detailed in the Metasys Smoke Control Wiring Technical Bulletin (LIT-636331). When using the DX-9120 connected to an NU-NET201-0 installed in an NCM300/350-2/-8, an MOV is installed across the NU-NET201-0 terminations. An MOV is also installed at each drop on the Echelon cable at the point it is connected to each DX-9120. The MOV is an AVX (Part No. VA100018A400) or equivalent. Capacitance is less than 350 pf. When using DX-9100/9120 product line for smoke control, the DX-9100-8990F base must be used. If the XP-9102 is used and the signal circuit leaves the room the XP-9102 is installed in, the protection is shown in Metasys Smoke Control Wiring Technical Bulletin (LIT636331). The MOV is a GE (General Electric) (Part No. V33-ZA-5) or equivalent rated at 33 VDC, 100A single pulse. The transzorbs in Metasys Smoke Control Wiring Technical Bulletin (LIT-636331) are installed on the base frame products. Only terminals in use and signal circuits leaving a room where a controller is installed have transient protection. The transzorb is a General Instruments (Part No. 1.5KE36CA), or equivalent rated at 1,500 watts and 36V. MOVs are installed on the AHU, UNT, and VAV products as shown in Metasys Smoke Control Wiring Technical Bulletin (LIT-636331). Only terminals in use, and I/O wiring leaving a room where a controller is installed, or wire more than 20 feet in length have transient protection. The MOV is a General Instruments or equivalent (Part No. V47-2A-7) rated at 47 VDC, 50A single pulse. 10 Smoke Control—Smoke Control UL 864 UUKL Compliance Checklist Y/N NA Person Verifying Notes Smoke Control—Smoke Control UL 864 UUKL Compliance Checklist 11 Notes Controls Group 507 E.
