Pre-Deployment Tests
A pre-deployment test on each beacon should be performed before and after
mounting. Short out the water switch and use a acoustic pinger receiver to
determine that the beacon is functioning.
For the ULB-362B series beacon,
check the beacon’s battery condition using a
digital voltmeter (see Battery Check, Page 9).
NOTE:
If the beacon does not operate properly, return it RJE International,
Inc. for service. (See Section 5 Return Procedures
for instructions on how to return the beacon.)
Battery Check
A high-impedance (minimum input impedance of 10 Megohms) digital voltmeter
can be used to measure the battery voltage. Use the following procedure to
measure the battery voltage:
1. Place the negative meter lead on the water activation switch.
2. Place the positive meter lead on any exposed surface of the housing.
Note: if testing a ULB-362PL/B37, the Pig-Tale conductors need to be
shorted together.
3. Read the voltmeter.
If the voltmeter reading is 6.0 volts or more, the beacon has
sufficient operating power.
If the voltmeter reading is below 6.0 volts, the battery needs to be
replaced. Follow procedures included in the B362-B30-01 Battery
Kit.
WARNING:
Failure to observe these precautions could result in the release
of hazardous chemicals.
