The following topics explain the function of your M2500 Smoke Guard
system.
What makes up the Model 2500 Smoke Guard system
Housing: The M2500 consists of a smoke-rated or fire+smoke-rated fabric
curtain assembly mounted within a steel housing. The housing contains a
tubular motor (systems over 20 feet in width have 2 motors), drive
components, system electrical sensors, and curtain.
A junction box within the housing receives wiring from the main controller
and distributes it to the motor/brake assembly as well as switches.
Guide system: The curtain is captured vertically on both sides by curtain
loops secured by guide rods. The guide rods thread through guides anchored
at each side of the system. Guides can be mounted on a wall face, recessed
into pockets or mounted within an opening jamb. The curtain deploys within
a continuous vertical slot in each guide.
Curtain: The curtain assembly is equipped with a bottom bar to seal the
curtain at the bottom and optional sensing edge to detect obstructions to the
deploying screen.
Controller: The main controller houses terminal blocks to receive main
power, a 24Vdc power supply, controller PCA, batteries and terminal blocks
to interface with curtain and building connections. It also contains a user
interface PCA, which has three indicator LEDs, and a test deploy switch. The
system is powered by an input source supplying 100-240VAC 50/60Hz. A
24VDC power supply provides power for the entire curtain system. Two 12V
sealed lead-acid batteries provide power should the primary power be lost.
Door activation switches: Optional door activation switches, installed on
the right as occupants approach the curtain from either side, allow occupants
to temporarily raise a deployed curtain approximately 7 feet in order to pass
through.
Keyed test-deploy switch. An optional keyed wall switch simulates an
alarm condition and is provided to facilitate testing. (NOTE: There is also a
test-deploy switch on the main controller near the user-interface LEDs.)
NOTE: The smoke detector or other initiating device is part of the building
smoke and fire alarm system and NOT a component of the Smoke Guard
system. However, it is an essential component, vital to the proper operation
of the system and all other connected equipment. The smoke detecting
system must therefore be inspected, tested, and properly maintained in
accordance with the equipment manufacturer’s guidelines as well as the
requirements of the authorities having jurisdiction. Emergency power to the
smoke detector should be maintained in accordance with NFPA 70.
