Components of the Metasys system running Release 8.1 software are Underwriter Laboratories (UL) 864UUKL/ORD-C100-13 UUKLC 10th Edition Smoke Control Listed. In applications requiring smoke control, this offering provides the protection of a UL 864UUKL listed smoke control system that has a lower installed cost and leverages the operational efficiencies of using a single system to provide HVAC and Fire Alarm smoke control. Earlier versions of the Metasys system also support UL 864UUKL 8th and 9th Editions. Many controllers and equipment that was qualified for these earlier editions have been brought forward for use in the 10th Edition. Also, if different editions of UL 864 must coexist in the same building, an Ethernet switch must be installed to isolate each UL 864 Edition.
The Metasys Smoke Control System consists of a set of hardware and software components specifically UL 864 10thEdition UUKL/ORD-C100-13 UUKLC smoke control listed. The listing applies to an indoor, dry environment only, where each Air Handling Unit (AHU) is located in an indoor, air-conditioned mechanical space. This listing also applies to an application where a Rooftop Unit (RTU) is located outside but the smoke control panel servicing the RTU is mounted in an indoor, conditioned mechanical space, with conduit wire runs to the RTU. However, this listing does not support applications where smoke control equipment is mounted in the RTU itself, or where equipment is exposed to a damp or wet environment. Lastly, the 10th Edition listing is intended for building systems in United States and Canada.
The smoke control applications are performed with an NAE and Johnson Controls MS/TP and N2 bus field controllers. The Metasys product code numbers with a dash U suffix indicate that they are for the Metasys Release 8.1 UL 864 UUKL/ORD-C100-13 UUKLC smoke control. Also, specific SCT and CCT software releases are spelled out in the listing. For details, refer to the Metasys System UL 864 10th Edition UUKL/ORD-C100-13 UUKLC Smoke Control System Technical Bulletin (LIT-12012487).
The smoke control offering provides a configurable yet straightforward application for receiving fire alarm signals, and it has the ability to control fans and dampers in a prescribed manner based on prioritized smoke control schemes. Smoke Control systems can also be activated automatically from a firefighter's smoke control station (FSCS). The FSCS enables a firefighter to execute real-time control from the FSCS panel. Automation Displays, Incorporated (ADI) has a UL/ULc Listed Firefighter's Smoke Control Station (FSCS) that integrates with the Metasys UL 864 10th Edition UUKL/ORD-C100-13UUKLC Smoke Control Listed Metasys Release 8.1 system. The UL/cUL 864 standard requires that one FSCS be included as part of the listed smoke control system.
