Maintenance Instructions
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 minimum is required).
• Check all electrical connections, including the power supply and the quick-connect 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, BUT 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."
Alarm system maintenance and horn level adjustment
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 attentiongetting ability.
2. The alarm horn is factory-set at the loudest possible sound level, 103 decibels at 10 feet. This sound
level will attract attention in shop areas with loud background noise levels or at large distances
outdoors.
3. If the alarm is used in a more quiet environment or over shorter distances, the sound level is easily
adjustable to lower levels (down to 78 decibels at 10 feet) with a simple external adjustment.
• Use 1/16" Allen wrench to adjust the sound to the appropriate alerting level.
• The adjusting hex screw is located on the front centerline of the horn grille about an inch from the
bottom.
• Turning the hex screw clockwise quiets the horn.
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 volts. Your connection should be water tight.
