Ajax DoorProtect Plus - Magnetic Contact with Shock Sensor - White

Intelligent Boundary Tracking with Impact and Forced Entry Detection The Ajax DoorProtect Plus Jeweller is a professional high-grade wireless opening detector that expands standard magnetic switch mechanics by grouping responsive spatial and physical vibration tracking. Engineered to safeguard high-risk entry boundaries like doors, windows, and roof skylights, this equipment alerts operators not just upon opening events, but reacts preemptively before a structural breach occurs. The integrated sensory hardware picks up subtle building vibrations generated by frame drilling, heavy hammering, or crowbar prying actions, routing an encrypted alarm event to the control panel within milliseconds.

Digital Multi-Axis Accelerometer and Hopper Window Tilt Tracking The internal layout of the device features a built-in high-precision three-axis accelerometer. This hardware tracking layer evaluates physical positioning and frame angle variants in real time, making it an optimal solution to protect bottom-hung windows or open ventilation structures. Property owners can safely arm the security grid while the window remains in ventilation tilt mode by establishing a custom angle threshold (adjustable from 5° upwards). If an intruder pushes the window further to gain entry, the detector registers the sudden angular twist and trips the alarm. An onboarding digital signal processor monitors shock durations, dropping consistent environmental noise from high wind or structural road traffic.

Deployment Versatility, Auxiliary Loops, and Secure Radio Infrastructure The retail packaging incorporates two high-performance magnets working at maximum 2 cm (large magnet) and 1 cm (small magnet) operational gaps, supporting tidy installations on complex PVC, wood, or aluminum frames. On its back frame, an extra auxiliary terminal block facilitates the direct integration of third-party normally closed (NC) hardwired sensors, such as external roller-shutter microswitches. Radio telemetry relies on the proprietary two-way Jeweller infrastructure, offering robust anti-jamming measures and adjustable central polling parameters.
