Ajax DoorProtect Plus Jeweller
Summary
The Ajax DoorProtect Plus Jeweller is an advanced wireless combined opening, shock, and tilt detector that provides comprehensive protection beyond simple door and window monitoring. Featuring both a high-quality reed switch and a built-in accelerometer, this sophisticated device detects not only opening and closing but also shock, vibration, and tilt movements, making it ideal for protecting doors, windows, safes, and other valuable assets.
Engineered with intelligent detection algorithms, the DoorProtect Plus Jeweller offers protection against chattering and includes an option to ignore single impacts, effectively preventing false alarms whilst maintaining reliable security monitoring. The device features three adjustable sensitivity levels for the shock sensor, allowing precise customisation through Ajax applications to suit specific installation requirements and environmental conditions.
Built on Ajax’s proven Jeweller communication technology, the detector provides secure encrypted wireless communication up to 1,200 metres with advanced anti-spoofing protection and frequency hopping capabilities. The device includes terminals for connecting third-party NC detectors, expanding system functionality, whilst the integrated chime feature enables Ajax sirens to provide distinctive audio notifications for door openings. With up to 5 years of battery life and simplified QR code installation, the DoorProtect Plus Jeweller delivers professional-grade security monitoring with exceptional convenience.
