M2500 Fire + Smoke Curtain

All three are vertically deploying Smoke Guard curtains built on the same platform. The M2500 is the standard fire + smoke rated curtain, with 2-hour fire endurance (UL 10D) and smoke and draft control ratings (UL 1784, NFPA 105). The M2500E adds manual egress: a split curtain per ICC AC77 and wall-mounted switches that retract the deployed curtain for passage before it automatically redeploys. The M2500 Draft is the draft curtain configuration, used for smoke and draft control where a fire endurance rating is not required.

The M2500 is a 2-hour (120 minute) fire endurance rated assembly complying with UL 10D and listed by Intertek Laboratories. It is also rated to UL 1784 for air leakage and meets the requirements for smoke and draft control assemblies defined in NFPA 105. System controls are listed in accordance with UL 864 for releasing devices.

The M2500 protects openings up to 60′ wide by 12′ tall, 50′ wide by 16′ tall, or 40′ wide by 20′ tall. Contact Smoke Guard for additional sizing options.

The system deploys on a signal from the local smoke detection system or a smoke control panel. It is a gravity fail-safe design, and each unit includes a battery back-up that can power the unit for up to 18 hours if primary power is lost, taking over automatically.

Yes, with the M2500E egress model. Its split curtain provides manual egress access per ICC AC77, and door activation switches mounted on opposing sides of the opening retract the curtain to allow passage. The curtain automatically redeploys after a brief pause while the alarm remains active.

Every system includes a mandatory testing key switch for the required periodic deployment tests, and Smoke Guard systems are installed and serviced by factory recognized personnel. Visit our Service & Repairs page to schedule service or learn more.
