Products Covered:
Smoke Guard Model 2100 (M2100) Smoke and Smoke & Fire curtain assemblies.
Product Description:
The Smoke Guard M2100 systems consist of a filament glass fabric (identified as SGTex-10a, SGTex-10b, SGTex-10c, SGTex-30 or SGTex-32), which is 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 vertical side guides during system deployment and the bottom edge of the curtain is attached to a weighted bottom 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 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.
The Smoke Guard M2100 system, utilizing any of the fabrics listed above, is recognized for use in smoke and draft control systems, as described in the tables below.
The Smoke Guard M2100 system, utilizing the SGTex-30 or SGTex-32 fabric, is additionally recognized for use in fire-resistance rated construction (as tested in accordance with UL10B, UL10C, UL10D and NFPA 252), as described in the tables below.
