Magnetic contact for fire resistant doorsets is a device used to monitor the opening and closing status of fire doors and feedback its status information to the fire door monitor. Its main function is to detect the opening and closing status of fire doors, and to provide the detected fire door status information to the fire door monitor host or its extension, in order to fully grasp the working status of the fire door and ensure its normal function. Welcome to purchase FBELE door magnetic switch.
The commonly used door magnetic switch consists of two parts: the component installed on the door leaf is a permanent magnet, with a permanent magnet inside to generate a constant magnetic field. The main body of the door magnetic switch is installed on the door frame, which has a normally open reed tube and lead wire inside. When the permanent magnet and reed tube are close (less than 5mm), the door magnetic sensor reed tube closes to indicate that the fire door is closed. When the permanent magnet leaves the reed tube for a certain distance, The reed is in a normally open state, indicating that the fire door is open.
For normally closed fire doors, the magnetic switch of the fire door is very important. When the electric door closer closes the door, a fire door magnetic switch is required to detect whether the door is fully closed and respond to the fire engine. Occasionally, normally closed fire doors are considered open. If there is no magnetic switch to detect the status of the normally closed fire door, when the normally closed fire door is considered to be in a normally open state, such as in the event of a fire, the normally closed fire door cannot block the fire or smoke, and the escape passage naturally does not have the function of escaping.
