DC24V electromagnetic door suction controller fire door suction controller (BJRANDE)

Main functions:
This controller and the electromagnetic door catch (electromagnetic release) form a normally open fire door control device. It is suitable for fire centers that only provide linkage signals (no control power supply) or if there is no fire center with its own independent fire detector. form an independent system.
Scope of application:
Major shopping malls, supermarkets and other places where fire electromagnetic door suction is installed.
Working principle:
Normally, the fire door controller outputs D to the electromagnetic door to make the fire door close and maintain a normally open state. In the event of a fire, the controller receives the fire alarm linkage signal (signal linkage type) or the independent smoke and temperature sensor signal (independent type). After the left and right doors are powered off respectively (delay seconds), the fire door is released and closed sequentially. At the same time, the buzzer in the controller continues. The sound simultaneously feeds back the release signal and outputs an alarm signal (external alarm) and a pulse signal with a width of about one second. After the fire alarm linkage signal (signal linkage type) or the independent smoke temperature sensor signal (independent type) disappears, the buzzer will sound continuously and the controller will enter the normal monitoring state after a delay of seconds.
