There is a considerable amount of legislation that needs to be taken into account when installing Fire Shutters.
For this reason we do not publish standard prices but would ask instead please that you contact us direct to discuss your requirements in greater detail. We will then be able to provide a free, no obligation quotation based upon our expertise and knowledge of current legal requirements.
There are two main methods of automatic operation, alongside the standard keyswitch.
A fusible link involves the use of solder as connection in the power circuit. Heat radiated from the nearby fire causes the solder to melt. This in turn activates the shutter thus closing the unit a controlled manner.
A fire relay means that the shutter is connected directly to the fire alarm system: When the alarm is activated the shutter will close. This type of operation is principally the most commonly used means of release. A volt free signal is required from the fire alarm.
A Battery Back Up unit will be required in most cases. The shutter requires a maintained supply. If under fire conditions there is a power failure, the shutter must have a means of ensuring closure. The unit provided will give the shutter power for at least one operation, under fire conditions.
As an option an Audio/Visual Warning unit can be used in connection with the Fire Shutter. This unit is connected to the alarm system, and operates, usually with a time delay. During this delay an alarm is sounded, warning those in close proximity to the shutter that it is about to close. This will allow personnel to exit the affected area.
