Ajax DoorProtect Plus - Magnetic Contact with Shock Sensor - Black

Intelligent Boundary Tracking for Sombre Architectural Elements The Ajax DoorProtect Plus Jeweller in black finish is a premium wireless security contact specifically optimized to maintain structural camouflage on dark-painted frames, security ironwork, or contemporary charcoal window sections. This device expands basic magnetic proximity logic by adding sophisticated real-time vibration tracking. It routes a critical alarm sequence to the control room before structural penetration is fully achieved, catching early frame drilling, crowbar leverage, or violent impacts on the entryway assembly.

Multi-Axis Electronic Accelerometer and Hopper Window Tilt Tracking The hardware design includes an onboard three-axis acceleration module that permanently evaluates vertical angles and orientation parameters. This feature ensures clean protection over hopper window structures or open transom setups. Users can safely arm the protective network while leaves are resting in tilt ventilation statuses by anchoring an electronic angle variance limit (from 5° upwards). If an intruder tries to open the leaf wider, the sensor identifies the sudden displacement and trips. The internal signal logic runs software noise dampening to filter out heavy wind chatter.

Wired Auxiliary Loops and Secure Jeweller Line Link The retail set features two high-performance black magnets rated for 2 cm (large magnet) and 1 cm (small magnet) working gaps. On its bottom base, a dedicated wired accessory dry contact loop (NC type) allows integration of external heavy roller-shutter microswitches. Wireless data transmissions rely on the proprietary two-way Jeweller infrastructure, preventing signal cloning through secure telemetry authentication and fast frequency hopping.
