General Specification
Curtain

(If smaller openings are adjacent to larger openings the laths on the smaller openings would normally be 76mm to ensure all match).

A profiled galvanised sheet hood is included as standard. A fascia can be included at extra cost on fit within applications.
Dependent on the fire rating of the shutter and the size of the opening, the shutter could require a hood support bracket.

Available Modes of Activation
Fusible Link release
On activation of the fusible link from a local heat source of 68°C this will send a signal to the relay which will signal the shutter to power down from the maintained supply or alternatively from the optional battery back up unit.
Fire Alarm link
By use of a fire alarm relay the shutter will close under power. The unit will require a maintained supply or alternatively we can supply with a Battery Back Up unit.
