Customized supply of inorganic cloth fireproof rolling shutter doo

  The controller is an important electric control facility for the fireproof rolling shutter door to complete the functions of fire prevention and smoke prevention, so it has become a necessary installation equipment 1
The rolling shutter control needs to connect the smoke detector and the temperature detector, and receive its fire alarm signal; When the smoke detector acts, the controller will control the curtain door to drop to 1
8m
After the temperature detector acts, the controller will control the rolling curtain to lower limit again and send out audible and visual alarm signal 2
The manual button of the controller needs to control the descent, rise, stop and operation of the fire shutter, and can automatically stop when it reaches the upper or lower limit position, and can send out action sound and light indication signals at the same time 3
When the controller needs to receive the half landing and full landing signals of the fire linkage equipment connected with it, it controls the fire rolling shutter door to complete the specified action and send out audible and visual indication signals at the same time 4
The controller can send fire alarm signals, fault signals and signals of upper limit, middle limit and lower limit positions to the fire alarm office 5
In the process of automatic lowering of the rolling shutter, the stop key of the manual button box can be used to realize the function of preferentially inserting the emergency stop and continuing to descend after delay
If the fireproof rolling shutter is below the middle limit during emergency stop, the control box shall also have the function of automatic control rising to the middle position and delaying, and then automatically descending to the lower position 6
In case of main power failure of the controller, short circuit and open circuit of the connecting line between power failure and quick release device or standby power failure, positive or reverse winding of roller shutter, short circuit and open circuit of the connecting line between smoke temperature detector and the controller, the controller shall be able to automatically send audible and visual fault signals and send signals to the fire linkage equipment in time 7
The control right of smoke detector, temperature detector, button box and fire linkage equipment of the fire shutter shall follow the sequence from high to low
When the fire alarm signal exists, manually pressing the down key of the button box on site will fail Smoke retaining vertical wall http://www
