Why there is no siren output all of sudden

1 comments:

The First Alert FA142C may have no siren output due to the following possible causes:

1. Power Issues – The alarm sounder requires a 12V, 2.0 Amp output. If the power supply is interrupted or the backup battery is depleted, the siren may not function.
2. Blown Fuse – The system has a 3A battery fuse (No. 90–12). If this fuse is blown, it could prevent the siren from operating.
3. Wiring Issues – Incorrect or loose wiring connections to the siren or control panel may cause a lack of output.
4. System Programming – If alarm outputs are not correctly programmed or disabled in the system settings, the siren may not activate.
5. Overloaded Power Output – The auxiliary power output and alarm sounder should not exceed 600mA total for UL installations. If overloaded, the system may shut down the siren output.

Checking these factors can help identify and resolve the issue.
