The Aeon Labs Door/Window Sensor is a battery-powered Z-Wave magnetic door/window sensor with an extremely small form factor. The D/W sensor will send radio signals up to 6 associated Z-Wave devices within its own Z-Wave network when the main unit separates from the smaller unit. Bidirectional mounting plate and push button allows for easy end-user installation. The Aeon Labs Door/Window Sensor also has tamper prevention capabilities and low-battery alerts.
