Curtain motion detector Ajax 39055 — outdoor, white

Ajax 39055 is a white curtain-style outdoor motion detector designed to monitor narrow zones such as windows, doors and perimeters. Built for exterior installations, the detector uses a focused detection beam to reduce false alarms and provides targeted monitoring of entry points and façades. The device integrates with Ajax security systems and is intended to protect against unauthorised access across specific linear areas.

How to use

Mount the detector to cover a narrow linear zone such as along a window, door frame or fence line so the focused beam crosses the intended protection area. Connect the device to an Ajax security system following the manufacturer's pairing procedure and verify coverage using the system's testing tools. Adjust angle and position to avoid direct exposure to sources of heat or small animals that could compromise detection accuracy.

Recommendations

Install the detector at the recommended height and angle for curtain-type sensors, keep the optics clean, and perform regular tests within the Ajax system to ensure reliable operation in outdoor conditions.
