Monitor multiple doors/windows using a single receiver by connecting additional Skylink Long Range Household Alert Door/Window Sensors. Designed for larger homes, the sensor's long range functionality allows it to signal the receiver (sold separately) from long distances (downstairs front door sensor to upstairs bedroom receiver, for example). 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).
