## Long description

Ajax DoorProtect White is a wireless, battery-powered magnetic door and window opening detector designed to monitor the opening and closing of doors and windows in homes and offices.

The reed switch is rated for over 1,000,000 toggles, and adaptive power management plus two-way communication enable periodic testing and remote configuration. Battery life reaches up to 7 years with one ping per minute.

Usage recommendations
Place the detector indoors within the specified operating temperature and humidity ranges. Test the connection quality and detection area remotely after installation.
