Fire door magnetic release Fire door electromagnetic release release switch

As an essential product in the automatic closing system of normally open fire doors, electromagnetic releases have been widely used in public fire protection places. Its main function is to keep the fire door open at ordinary times. When a fire occurs, it receives the fire linkage signal and automatically releases the fire door, so that the fire door can be closed under the force of the door closer, thereby effectively blocking smoke and flames and releasing the fire door. The signal output is fed back to the fire control center. (1) Features and functions:
. Normally no electricity is used and there is no power consumption
. Immediately return to the unused state and low power consumption after release
. The feedback signals include both passive feedback signals and active feedback signals, which are convenient for users to choose and use
. It is equipped with a manual release to facilitate installation and debugging or to release and close the fire door when there is no power
. Equipped with electric reset. After the electric release, confirm that the fire alarm is cleared before manual reset and buckle again. The operation is safe and reliable
. Exquisite appearance, compact structure and easy installation.
