Product Covered:
Smoke Guard Model M4000 curtain assembly.
Product Description:
The Smoke Guard M4000 systems consist of fire and smoke resistance rated filament glass fabric (SGTex-30 or SGTex-32) that is folded into a sheet metal housing. Contained in a sheet metal housing, the curtain assembly is comprised of drive means and associated electronics. The curtain edges are captured in optional vertical side guides (depending on the shape of the system). During system deployment, the bottom edge of the curtain is attached to a weighted bottom pan. Aluminum finish covers may be attached to the weighted bottom pan using pressure-sensitive adhesive with or without the use of rivets.
If the system encounters an alarm, the releasing device activates deploying the curtain. In the event of main power failure, an integrated battery system maintains the system in ready position. Should main and backup power systems fail, the curtain will deploy in a controlled manner under the influence of gravity (Gravity Fail Safe). If required, wall switches are provided on each side of the curtain, allowing occupants to momentarily raise the curtain to egress. After the alarm condition clears, the curtain automatically rewinds into the housing.
