Ajax DoorProtect Jeweller (Black)

DoorProtect is a wireless opening detector designed to secure doors, windows, and skylights against unauthorized access. Built around a high-grade British reed switch rated for over 2 million openings, it detects perimeter breaches instantly and transmits an alarm in 0.15 seconds. Featuring a built-in terminal for connecting additional third-party wired detectors and operating on a single pre-installed battery for up to 7 years, DoorProtect delivers dependable, wire-free perimeter protection.

Key Highlights

• Instant Opening Detection: Leverages a sealed reed switch that triggers when the magnetic field breaks as a door or window opens.

• Dual-Magnet Versatility: Includes both a small magnet (up to 1 cm threshold) and a large magnet (up to 2 cm threshold) for flexible mounting on narrow frames or complex profiles.

• Extended Wire Integration: Features an NC (normally closed) terminal clamp to connect third-party wired detectors (e.g., additional door contacts, vibration sensors, or roller-shutter switches).

• Up to 7 Years Battery Life: Powered by a pre-installed CR123A battery with intelligent power regulation based on signal distance.

• 1,200m Jeweller Range: Enjoys secure two-way radio communication with the hub across vast open-space distances.

• Anti-Sabotage Architecture: Includes an integrated tamper switch against frame detachment, device authentication to stop spoofing, and immediate jamming detection with frequency hopping.
