Insulated Roller shutter
Product Details
Available in galvanised or polyester powder coated finish to a standard RAL or BS colour.
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, acting as a smoke curtain for up to 5 minutes before closing fully.
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.
The shutter can be operated normally as a security shutter via a key switch or rocker switch.
