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.
