Ajax DoorProtect G3 Fibra Wired Door and Window Opening Detector (4823114015144)

The Ajax DoorProtect G3 Fibra (38245) is a professional Grade 3 wired opening detector designed for high-security integration within an Ajax Fibra bus system. This device utilizes a high-end reed switch to monitor the state of doors, windows, and hatches, triggering an immediate alarm upon magnet displacement. As a Grade 3 certified component, it features advanced protection against magnetic masking and includes a built-in accelerometer to detect unauthorized tilting or physical displacement, making it suitable for high-risk commercial environments. The Fibra wired technology ensures secure, encrypted communication with the Hub at distances of up to 2,000 meters while maintaining exceptionally low power consumption. Housed in a compact white casing, the detector supports the connection of an additional third-party NC (normally closed) detector and is fully configured via the Ajax mobile or desktop applications.
