5. Operating Instructions
Once installed and paired with your SimpliSafe Gen 3 system, the Auxiliary Siren operates automatically in conjunction with your alarm system:
- Alarm Activation: When your SimpliSafe system detects an intrusion (e.g., through a triggered sensor) and the alarm is activated, the Auxiliary Siren will sound simultaneously with your system's Base Station siren.
- Siren Volume: The siren emits a loud 105dB sound, designed to be heard over a wide area.
- System Control: The siren's operation is managed through the SimpliSafe App and your system's keypad. Arming or disarming your system will control the siren's readiness.
- Testing the Siren: To properly test the full alarm sound of the siren, you may need to trigger a full alarm in practice mode or contact SimpliSafe customer support for guidance. The in-app test mode may only produce a brief beep, not the full 105dB alarm. Always protect your ears during testing.
6. Maintenance
The SimpliSafe Auxiliary Siren requires minimal maintenance to ensure optimal performance:
- Battery Replacement: The siren is powered by 4 AA alkaline batteries. While designed for long life, monitor your SimpliSafe App for low battery alerts. Replace all four batteries simultaneously with new, high-quality alkaline batteries when indicated.
- Cleaning: Periodically wipe the siren's exterior with a soft, dry cloth to remove dust and debris. Avoid using abrasive cleaners or solvents.
- Connectivity Check: If you experience any issues with the siren, check its connection status in the SimpliSafe App to ensure it is still communicating with the Base Station.
7. Troubleshooting
If you encounter issues with your SimpliSafe Auxiliary Siren, consider the following troubleshooting steps:
- Siren Not Sounding:
- Check battery levels in the SimpliSafe App. Replace batteries if low.
- Ensure the siren is properly paired with your Base Station. Re-pair if necessary via the SimpliSafe App.
- Verify that the siren is within range of the Base Station (up to 1000 feet in open air, but walls and interference can reduce this).
- False Alarms: While unlikely for a siren itself, if your system is experiencing false alarms, investigate the triggering sensor. The siren will only sound when the main alarm is triggered.
- Connectivity Issues: If the siren frequently loses connection, try relocating it closer to the Base Station or adjusting its position to minimize interference.
- Testing Discrepancy: As noted in operating instructions, the in-app test may not produce the full alarm sound. To hear the 105dB alarm, a full system alarm must be triggered (e.g., in practice mode).
For persistent issues, refer to the SimpliSafe App's help section or contact SimpliSafe Customer Support.
