Operation
Sliding fire doors are designed to close and divide large openings, both in a permanently open position and for intensive use. They can be operated manually, semi-automatically, or automatically. Closing is ensured by a counterweight acting on the door leaf (*). When the alarm signal triggers an impulse to the electromagnet (24 VDC) or the thermal fuse reaches a temperature of 68ºC, the door releases and is pulled by the counterweight, leaving it completely closed. With the action of the fire, the intumescent seal installed in the smoke barrier labyrinth expands around the entire perimeter of the door, sealing it.
Exceptionally, in semi-automatic and automatic operation, closing is guaranteed by an inverter
