FORTRESS DBF501 FIRE CURTAIN

Fortress DBF501 Fire Curtain is designed to protect escape routes from the effects of fire, thus enabling building occupants to reach final exits. The fire curtain will protect the building contents by limiting the spread of fire and smoke while still allowing the passage of people or goods from one compartment to another.

Operation
BS EN 12453 DBF501 Drive System™ 240 Volt single-phase in-barrel operator and 24 Volt activation system linked into the building fire alarm system. On receiving a signal from the fire alarm, the control panel will activate the drive-roller mechanism to lower the curtain under controlled descent to a pre-determined height.
In the event of power failure from a mains supply, we recommend that a Fortress FCPB™ Power Supply backup system is used.
NB: Control panel must be fitted to a 6amp/non-switched, fused, maintained essential supply.
