Fire Shutters are a increasingly popular security product. Westwood Security Shutters Ltd offer fire protection at up to four hours greater than would be the case for a standard door or shutter. They can be used to portion off and protect a particular part of a building, the whole building, or even provide protection between floors (horizontal fire shutters).
There are three main methods of automatic operation. A fusible link involves the use of solder as connection in the circuit: heat radiated from a nearby fire causes the solder to melt and this activates the door.
A Fire Relay means that the shutter or door is connected to the fire alarm system: when he alarm is sounded, the shutter or door activates.
Finally, an delayed Audio/Visual Warning used in connection with the Shutter this is connected to the alarm system and operates usually with a time delay very similarly to one using a fire relay. During this delay an additional alarm is sounded, warning those in close proximity that the door is about to close, thus allowing them to exit the affected area.
