Product Covered:
Smoke Guard Model 2500E fire and smoke curtain assembly
Product Description:
The Smoke Guard M2500E system consists of a filament glass fabric curtain (constructed of SGTex-30 fabric) wound onto a tube containing an internal drive system. The curtain incorporates one or more overlapping egress passages constructed of SGTex-32 fabric (see below for further details). Contained in a sheet metal housing, the curtain assembly is comprised of support rollers and associated electronics. Sewn loops along 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 M2500E system is recognized for use as a fire and smoke control system in fire-resistance rated construction, as described in the tables below.
To maintain compliance with the listed fire ratings and an air leakage ≤3.0 cfm/ft2 at up to 0.10 in. of w.c. at ambient and elevated temperatures, the minimum curtain area that may contain two overlapping egress passages is 250 ft2. The minimum curtain area that may contain three overlapping egress passages is 350 ft2. A minimum of 4 lineal feet of curtain must remain between egress doors. Overlapping egress passages in curtains that are less than or equal to 102 inches in height shall be a maximum of 80 inches in height.
The Smoke Guard M2500E system must be installed in accordance with the manufacturer’s instructions.
