MDFS4 Rolling Steel Fire Shutter:

The MDFS4 fire rated rolling shutter incorporating a unique tubular motor resulting in a compact design.

Available in galvanised or polyester powder coated finish to a standard RAL or BS colour.

Tested in accordance with BS476 part 22 by Bodycote Warringtonfire under report reference WF148919 the shutter satisfies integrity criteria for up to 240 minutes fire resistance. Suitable for connection to and in accordance with smoke, heat, exhaust and ventilation detection systems (Shevs).

The fire shutter package includes key or rocker switch operation, alarm interface panel, audio visual system and battery backup.

The shutter can be operated normally as a security shutter via a key switch or rocker switch.

On receipt of a fire signal, heat or smoke detector signal, the battery back-up drives the shutter to the closed position. Optionally the shutter can be driven closed on detection of mains failure.

Imminent door closure is indicated via an audio visual signal. After a time delay adjustable between 0 and 60 seconds, the door will close automatically under power. Once the alarm signal ceases or mains power is re-established the door automatically resets and can be opened normally. The door may also be set to part close to act as a smoke curtain for up to 5 minutes before closing fully.
