When the monitored window or door is opened, the receiver alerts you by flashing and either beeping or sounding the alarm. FEATURES: Notifies you when your door or window is open. Operating range up to 800 feet. Supervised: automatically monitors the sensor and its battery condition. Magnetic type contact sensor. NOTE: Requires the Skylink Household Alert Long Range Receiver HA-434RL (sold separately).
