AJAX Magnetic contacts

More than magnetic contacts

AJAX wireless magnetic detectors consist of two parts: a reed relay and a magnet in a separate housing. A reed relay is an electrical contact in a sealed container that closes when the magnet is close and opens more than 1 cm away. In this way, the sensor registers both opening and closing and the security system can notify users.

Sensors for doors and windows are an essential part of any alarm system. They can trigger alarms, run automation scenarios and integrate sensors from third parties through the Ajax security system. All these features make the detectors an important part of a smart home.

Features of the AJAX magnetic contacts

Detect intruders before they enter a building

The standard DoorProtect from AJAX detects the opening and closing of doors. In addition, the AJAX DoorProtect plus detectors can detect powerful shocks, register a change in the slope and receive signals from third-party wired sensors. So if there is an attempt to kick in or dismantle a door, the detectors can trigger an alarm. 

Combining security and comfort

Thanks to the accelerometer built into the detector, both normal windows and dormer windows can be opened without any problem for ventilation. If the angle of the window changes by more than 5°, the security system is triggered.

Make third-party sensors smart

DoorProtect Plus allows you to integrate a shutter motion sensor into the AJAX security system and set the conditions for alarm activation in the mobile app.

Automation of security

Via the automation scenarios, you can set the light to come on, a smoke cannon to be activated, or the door to be locked if a movement detector sounds the alarm. Be fully prepared for intruders with an arsenal of functions.
