The DWC-55 Roller Shutter Door Sensor is used for rolling gates. 

When the Metal Magnet and the Metal Reed Switch are 

separated more than 2cm, it will transmit wireless alert signal to 

the connected control panel immediately. The lifespan of the 

battery depends on the frequency of opening and closing the 

door/gate, the normal battery’s service life is about 12 to 15 

months.
