FUSIBLE LINK RELEASE MECHANISM:
A soldered link designed to melt at 680C separates and releases the clutch on the electrically operated shutters, putting the shutter into fire mode making it close. On activation of the release mechanism, the shutter’s rate of descent is controlled through the gears being constantly engaged. The rate of descent is approximately 100mm per second. The clutch can be reset and the door can then be raised and lowered in the normal fashion. The motor unit has a facility to simulate a fire test via a pull and reset cord.
AUTOMATIC RESET SOLENOID RELEASE MECHANISM (FIRE ALARM SYSTEM):
The auto reset solenoid release designed to be connected to the fire alarm system. Upon receipt of a 24 volt 0.5amp signal the clutch will disengage allowing the door to close under controlled descent. When the door is returned to open position after removal of the fore signal the solenoid will re-set itself automatically. This is commonly used and ideal for frequent testing.
