The wireless contact sensor is an accessory of the smart alarm system. It is easy to install and fits on most doors and windows. When transmitter and magnet are apart, the sensor triggers the alarm. The transmitter can be attached to either side of the magnet. With low battery warning function, users will be informed to replace the battery by App when needed. With newly developed "Ready to Arm" feature, the user will be notified if door or windows are open when arming the system.
