Building regulations require that openings in fire resisting walls or partitions must have a door with an equivalent fire rating to that of the wall or partition.
Heat radiated from a nearby fire causes the fusible link to melt and this activates the shutter.
or, using fire relay connected to the fire alarm system, when the FS alarm is sounded, the shutter activates.
or, a delayed Audio/Visual Warning system in connection with the Fire Shutter is connected to the alarm system, and operates usually with a time delay very similarly to a fire relay. During this delay an additional alarm is sounded, warning those in close proximity to the door that is about to close, thus allowing them to exit the affected area.
