- When replacing batteries, ensure the siren is powered off and disconnect the main power adapter.
6.2 Cleaning
Clean the exterior of the siren with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Siren does not power on. | No power from adapter; ON/OFF switch is off; backup battery depleted. | Check power adapter connection and outlet. Ensure ON/OFF switch is in the ON position. Allow time for backup battery to charge or replace CR123A batteries. |
| Siren does not sound when a sensor is triggered. | System is not armed; sensor not paired; sensor malfunction; siren not receiving signal. | Ensure the system is armed. Verify the sensor is correctly paired with the siren/control panel. Check sensor battery. Ensure siren is within range of the control panel/sensor. |
| False alarms. | Sensor sensitivity too high; environmental factors (e.g., pets, wind); interference. | Adjust sensor sensitivity if applicable. Reposition sensors to avoid environmental triggers. Check for sources of wireless interference. |
| Cannot pair new accessories. | Siren not in pairing mode; accessory not compatible; accessory not triggered correctly. | Ensure the siren is in pairing mode (press SET button). Verify accessory compatibility (PT2262 encoding). Trigger the accessory promptly after entering pairing mode. |
