防盗卷帘门报警器有三种,一种是卷帘门磁,分为两部分,一部分安装在地面,一部分安装卷帘门上,它是通过两部分之间磁力的变化而产生报警,关闭门就吸合在一起,打开门就关闭。
There are three kinds of anti-theft curtain door alarm devices. One is the curtain door magnetism, which is divided into two parts. One part is installed on the ground and the other part is installed on the curtain door. It generates alarm through the change of magnetic force between the two parts. Closing the door sucks together and closing the door.
第二种是被动红外,被动红外是通过热释电传感器来感知红外热源物体的存在而产生报警输出。

The second one is passive infrared, which produces alarm output by sensing the existence of infrared heat source objects through pyroelectric sensors.

第三种就是红外光栅,红外光栅分为主、从之分,分别安装在门两侧,主机发射红外光,从机接收。一旦有人在中间位置,导致从机无法接收主机发出的红外光,光栅就报警。
The third one is infrared grating, which is divided into master and slave. The infrared grating is installed on both sides of the door. The host transmits infrared light and receives it from the slave. Once someone is in the middle position, the slave can not receive the infrared light from the host, the grating will alarm.
