The DWC-D4F 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.
