Manufacturer overview
Wireless reed-switch opening detector with shock and tilt sensors
Guardian for doors, windows, and valuables. DoorProtect Plus Jeweller is designed to detect intrusion and burglary attempts, offering comprehensive coverage for doors, windows, skylights, and vaults. Equipped with a reed switch as an opening sensor, the detector features protection against chattering in its operation. Two magnets of different sizes provide more installation options. The device also detects shock and tilt with a built-in accelerometer, protecting the facility even when windows are in airing mode. All in line with the Ajax user experience, ensuring quick and easy device installation.
No intruder goes unnoticed. DoorProtect Plus Jeweller features a durable reed switch that guarantees decades of trouble-free operation. Housed in a resilient plastic capsule, the reed switch remains intact during transportation, even in case of drops. Two magnets of different sizes provide more installation options: the small one operates at a distance of up to 1 cm from the reed switch, and the large one — up to 2 cm. The detector functions effectively irrespective of magnet placement.

Immediate detection of threats. The built-in accelerometer swiftly responds to shock, detecting potential burglary attempts, such as door forcing and vault breaches. The shock sensor features three sensitivity levels that can be adjusted to match facility specifics. The detector can also ignore a single impact to minimize the risk of false alarms triggered by external factors. The installer can choose the appropriate settings for accurate detection, even in environments with vibrations from neighboring constructions or heavy passing traffic.
Windows protection in an airing mode. The built-in accelerometer protects open windows, seamlessly adapting to diverse facility specifics. For doors and windows, installers can set up a tilt angle of the detector, ranging from 5 to 25 degrees. The system swiftly detects even the slightest deviations from the initial value and provides adjustable tilt alarm delay, ranging from 1 second to 1 minute. If the tilt angle surpasses the initial value for longer than a specified time, the system raises an alarm.
Wire-free flexibility and reliable performance. Baseline devices operate without any wires, offering maximum flexibility during installation. The pre-installed CR123A battery from proven manufacturers ensures a hassle-free setup, requiring no additional steps to start operating the devices. In addition to real-time testing during battery production, Ajax Systems inspects every unit to ensure the accuracy of the battery characteristics. The battery can be easily replaced after approximately five years of autonomous operation. Its status is always accessible in the Ajax app. Users and security companies receive low battery level notifications months in advance, allowing for timely replacement without rushing.
