Instructions for use of electromagnetic door catch 1. Product usage
The electromagnetic door catch is a standard supporting product for normally open fire doors. It is used to keep the door in a normally open state and achieve the purpose of central control linkage in non-fire situations. The door is in a normally open state to facilitate the passage of personnel. When a fire situation occurs, the fire controller cuts off the door suction power, closes the door quickly and generates a feedback signal to prevent the spread of smoke, fire and toxic gases.
