Setup, Compatibility & Care
To begin, install the included 9V 6F22 battery into the rear compartment. Once powered, use the `ON` switch to activate the unit. You must pair this device with your KERUI alarm control panel according to the specific pairing instructions provided with your hub (usually involving triggering the sensor while the panel is in 'Add Accessory' mode).
Maintenance Tips:
- Dust the sensor lens occasionally with a dry microfiber cloth to ensure clear infrared reception.
- Periodically test the device by walking past it to ensure the alarm panel receives the signal.
- Replace the 9V battery immediately once the low battery indicator flashes.
- Keep the device away from humid environments to protect internal circuitry.
