What to do if the Bradley Security System signal light and horn don't work when water flows?
- JjessicafreyAug 12, 2025
If the signal light and horn aren't working when water flows, there could be several reasons. First, ensure the circuit breaker or fuse is supplying power to the signal station. Then, check the two 3 Amp 24VDC fuses on the print circuit board in the signal station enclosure. Also, verify that 24VDC is being supplied from the power supply. Make sure the water flow direction matches the arrow on the flow switch body and that the water flow is sufficient (2.4 gallons per minute is required). Finally, check all electrical connections, including the power supply at the quick-connect cable, from the signal station to the flow switch.
