Troubleshooting
1. If the alarm (horn and strobelight) does not operate when water flows:
‡ Check that the circuit breaker or fuse is supplying power to the alarm.
‡ Check that the direction of water flow corresponds to the arrow on the flow switch body.
‡ Check that water flow is sufficient (2.5 gallons per minute is required).
‡ Check all electrical connections, including the power supply and the waterproof cable from the
flow switch to the alarm.
Strobe flashtube replacement
1. Loosen the locking band and remove the clear plastic dust cover from the top of the strobelight.
2. Loosen (but do not remove) the three screws holding the amber dome in place. Rotate the dome
slightly clockwise and remove the dome.
3. Remove the flashtube assembly by simply unplugging it from the top of the strobelight.
4. Replace the flashtube assembly with a new one.
NOTE: Avoid touching the flashtube glass with your fingers. Be sure the flashtube assembly is firmly
plugged into the socket.
5. Reattach and tighten the amber dome.
6. Reattach and tighten the clear dust cover.
7. Test the alarm as described in Step 5 "Test the alarm system" on page 5.
Alarm system maintenance
1. The Bradley Alarm System is designed to be virtually maintenance free. An occasional damp
cloth wiping of the clear dust cover is all that is needed to ensure maximum visual attention-
getting ability.
Remote Sensing Option
If remote sensing is wanted, remove the pipe plug from the side of the junction box. Connect the
extra black wire (common to both switch arrangements) and the blue wire (normally open switch
arrangement) or red wire (normally closed switch arrangement) to your application per local
electrical codes. The switch is rated at 5 amps at 120 and 220/240 volts. Your connection should
be water tight.
