For internal, commercial applications.

Fire rated roller shutters with 30 minutes up to four hours' fire resistance and tested to BS EN 1634-1.

Features and benefits:

• Least cost option is that the door be activated by a sacrificial fusible link. This will activate the door independently when the heat around the link reaches approximately 72°C. It will not be triggered by smoke and will require replacement before the door can operate normally again. Must be supported by risk assessment to ensure compliance to BSEN 12453.
• Alternatively a fire roller shutter will be part of an overall fire (and smoke) control system. The fire roller shutter motor comes complete with a 24V d.c. energized to hold actuator. When the actuator is de-energized it will release the drive brake and the door will close by controlled descent in a safe and controlled manner (fail-safe).
• As an option the door will be supplied with a fire control panel which allows a volt-free signal to used to allow closure. The fire control panel also has the ability to hold open the shutter during power failure for up to 60 minutes via internal batteries and comes with audio/visual warnings.
• During installation and commissioning the actuator must be energized to prevent the motor turning and the door closing. The fire shutter is reset by re-energizing the actuator and giving an open command.
• A combined fusible-link and actuator option is also available including upgraded sophistication to suit client needs.
