Wireless PIR Motion Sensor Alarm Detector with Battery

Add wireless movement detection to a compatible W202 or W181 alarm system. This PIR sensor sends a signal to the host when it detects activity within its sensing area.

✅ Monitor a selected indoor zone - Passive infrared sensing helps the alarm host notice movement through the monitored area.

✅ Avoid a signal cable run - Wireless transmission lets you position the sensor without wiring it to the panel.

✅ Start with the supplied battery - The included CR2032 battery provides a power option for initial sensor setup.

A Motion Sensing Point for Your Alarm

Place the detector so movement crosses the area you need to monitor. Its 45-degree detection angle defines the sensing zone, with a stated working range of 6 to 8 m.

The sensor is an accessory for a compatible alarm host, which handles the system's response. SMS or call notifications depend on the host's supported configuration rather than being a standalone feature of this detector.
