## Summary description

Ajax DoorProtect Plus Black is a wireless, battery-powered door sensor designed to detect door opening and tampering. It integrates with Ajax security systems to trigger alarms and notifications, suitable for homes and small businesses.

## Long description

Ajax DoorProtect Plus Black is a wireless, battery-powered magnetic opening detector with built-in tilt and shock sensors. Designed for indoor use, the device detects door and window opening, inclination relative to the ground and impacts. It connects to an Ajax Hub via the Jeweller radio protocol and supports an external wired detector input, providing reliable intrusion detection for homes and small businesses.
Advantages
DoorProtect Plus communicates with the Ajax Hub over a secure, encrypted channel with frequency-hopping and anti-jamming features. The detector uses a British-made reed switch rated for over 1,000,000 actuations and an accelerometer that senses vibration and impacts. It supports authentication and tamper protection, adjustable signal polling intervals (12–300 seconds), and power saving that extends battery life up to 5 years under typical settings. The unit can be tested and configured remotely and pairs with the hub in one click.
