Usually open the door, you will find the door was absorb, in there, this is a door suction device, which is used to absorb the door, so as not to because of the wind, collision, the door has been swaying, sound, affect the normal life. To this, today to introduce electromagnetic door stopper? When the choose and buy, install, and need to pay attention to what?

A basic introduction of electromagnetic door stopper

The so-called electromagnetic suction door, is a device by the door of the current control. So, this electromagnetic door stopper is how to work? Power is simply to electricity to absorb the door, open the door, so this kind of device often and fire door controller together. At ordinary times, presenting the state power, the electromagnetic absorbing live fire door, door, fire door also keep open, once fire, after receiving the fire signal, will automatically cut off the power supply of electromagnetic door suction, achieve the effect of the remote control, fire door shut down automatically, it is to have the fire door fire prevention effect. The status of the device, of course, considering the one thousand accident, remote control failure, so also setting field manual, close the fire door directly. Such two kinds of Settings, improve the security of electromagnetic door suction, can make fire door more effectively play a role.

2 the classification of the electromagnetic door stopper and installation

Electromagnetic suction door also have the classification, general according to the scene after the fire door to open the door and the distance of the wall is divided into three kinds, one kind is a wall, metope is suitable for installation wall type electromagnetic door after door open. One kind is to type, door open after no suitable for metope installed type electromagnetic door stopper. Another kind is the chain, the door opened with metope suits to install chain but far away from the wall electromagnetic absorption. Which depends on the specific site conditions to select the electromagnetic absorption. At the same time, the installation, pay attention to subject the magnet mounted on the wall, the suction plate installed on the door, and the base must be careful not to put wrong!

3 how to choose and electromagnetic suction door

It's also important to choose appropriate electromagnetic door suction, the first thing to choose suction suitable, suction is too young to good absorb the door, but also not line, suction is too big if there is an emergency can't break, can't turn off the fire door! Electromagnetic door to suck in addition to better automaticity, manual performance is better also, so that in case of an emergency automaticity if failure, can also be manually controlled. When choosing the best choice to hold the electromagnetic body, suction plate and then choose can activity, it can satisfy various installation requirements. There is demand of users can also choose the sort of can feedback signal fire electromagnetic suction door, when there is a fire, rapid feedback to the fire protection system, urgent rescue!
