Product Covered:
Smoke Guard Model M3000 horizontal curtain assembly.
Product Description:
The Smoke Guard M3000 horizontal systems consist of smoke resistance rated filament glass fabric (SGTex-30 or SGTex-32) wound onto a tube containing an internal drive system. Contained in a sheet metal housing, the curtain assembly is comprised of support rollers and associated electronics. The curtain edges are captured in side guides during system deployment and the leading edge of the curtain is attached to a leading edge bar. 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. Should the main power systems fail, the curtain will deploy in a controlled manner using a battery backup system. After the alarm condition clears, the curtain automatically rewinds into the housing.
