User’s Manual January 2018
1Description
This section provides a general descriptive overview of the beacon, its theory of
operation, and use.
The ULB-362B Series Underwater Locator Beacons are durable, water-activated,
underwater location aids. A Power Loss version is also available. The ULB-362B
series beacons can be ordered in several frequencies, 27kHz, 37.5kHz and
45kHz. The beacons transmit an acoustic signal once every second after
activation. The acoustic output for the 30 day battery will remain above 157.0dB
for 30 days.
RJE International, Inc. also offers a standard mounting bracket (P/N ULB362-02).
The bracket allows the beacon to be securely mounted (Please contact RJE
International, Inc. if the mounting bracket does not meet your needs). The ULB-
362B beacon is shown in Figure1-1. The beacon is also shown installed in its
standard mounting bracket in Figure 1-2, and a dimensional outline of the beacon
is shown in Figure 1-3.

Figure 1-2 Installed in Mounting Bracket
External Construction
The beacon is contained in a water-tight aluminum case capable of
withstanding high-impact shock and deep-water immersion. As shown in
Figure 1-2, one of the end caps has a built in water-activated switch that
causes the beacon to begin transmitting when the switch comes in contact
with water.

ULB-362B Underwater Locator Beacon 3
User’s Manual January 2018
Internal Construction
The major internal components of the beacon include a printed circuit board
assembly, a urethane-encapsulated transducer assembly, and a battery. The
battery is contained in its own, separate, user accessible compartment.
Theory of Operation
The printed circuit board assembly generates all the necessary logic functions
to produce a pulse with the desired characteristics. The pulse is then
transformed from a CMOS level square wave to a much larger sinusoidal
pulse by a transformer. The output of the transformer drives the epoxy-
encapsulated transducer, which propagates through the housing in the form
of a tuned acoustic signal based on the frequency of the beacon (27kHz,
37.5kHz, or 45kHz).
Locating the Beacon
When the beacon is immersed in water, it will begin to radiate an acoustic
signal which can be received and transformed into a visual signal by using the
RJE International, Inc. STI-350, DTI-300A, DPR-275 or VADR6000M
Acoustic Receivers. When using the STI-350 Surface Acoustic Receiver, the
general vicinity of the ULB-362B beacon can be located from shipboard. After
the area is known, a diver can be deployed with the DTI-300A diver acoustic
receiver, which will give the exact location of the beacon. When recovery is
too deep for diver operations, a VADR receiver, mounted on a ROV, can be
used. Other equivalent pinger receivers may also be used to relocate the
ULB-362B beacon.

3Installation and Checkout
This section encompasses the installation considerations and procedures for
mounting the beacon using the mounting bracket kit, and a pre-deployment test
that can be conducted using a digital voltmeter.
Installation Considerations
To minimize the probability of physical damage or inadvertent activation, the
following precautions should be considered when mounting the beacon:
▪The beacon should normally be mounted onto a sturdy structure without
weakening the structure itself.
▪The beacon should be mounted in an area guarded against heavy
equipment tearing loose and striking the beacon and should be mounted in
a way that provides convenient access during regular inspections and tests.
▪The beacon should be mounted in an area where sound absorbent
materials are not present. Avoid affixing labels to the beacon or any other
material that would affect the acoustic beam.
▪The shelf life of the battery will be decreased when exposure to higher
than normal temperatures. The maximum temperature where the beacon
is mounted should not exceed 71ºC (160ºF).
▪Nonconformance to the mounting instructions or intended use may void
the warranty.

User’s Manual January 2018
Installation Procedures for ULB-362B and
ULB362-02 Mounting Bracket
Carefully unpack the beacon and inspect it for shipping damage. If any
damage is evident, it should be reported to the freight carrier and to RJE
International, Inc. If ordered, the mounting bracket kit includes an aluminum-
mounting bracket, an aluminum end plate, three drilled (for lockwire) socket
head cap screws, and three lock washers.
NOTE: Before installing the mounting bracket, be sure that it will be
possible to install and remove the beacon once the bracket is
installed.
To mount the beacon, perform the following steps:
1. Ensure the beacon is mounted in the vehicle so that it has a clear path to send
the acoustic signal. Avoid mounted it behind other equipment.
2. Mount the beacon with the water switch down to prevent accidental activation.
3. Refer to the mounting bracket hole pattern shown in Figure 3-1 and drill four
0.19in (0.5cm) diameter holes.
4. Secure the mounting bracket with four 10-32 stainless steel screws and
associated hardware (not supplied) as shown in Figure 3-2.
5. Slide the beacon into the bracket as shown in Figure 3-3. Rotate the beacon
until the battery date is visible and secure it in place with the end plate and the
three drilled socket head cap screws.
6. Lockwire the drilled screws and clean the water activation switch (refer to section
4 Beacon Cleaning).

Installation Procedures for ULB-362/PL
Carefully unpack the beacon and inspect it for shipping damage. If any
damage is evident, it should be reported to the freight carrier and to RJE
International, Inc.
To mount the beacon, perform the following steps:
1. Ensure the beacon is mounted in the vehicle so that it has a clear path to send
the acoustic signal. Avoid mounting it behind other equipment.
2. Mount the beacon with the water switch down to prevent accidental activation.
3. Male E/O Pigtail Connector, provided with the unit, is wired to Vehicle’s
electronics module through a penetrator.
4. A ‘normally closed’ electrical relay is installed in electronics module of the
Vehicle. This relay is wired to the vehicle’s power supply. (see below diagram)

User’s Manual January 2018
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.

4Beacon Maintenance
This section covers the cleaning, recommended testing interval, disposal,
storage procedures, and battery replacement for the ULB-362B Series
Underwater Locator Beacons.
Beacon Cleaning
The end cap with the water switch should remain free and clear of dirt,
grease, and dust. The beacon should be cleaned with a mild detergent and
dried thoroughly with a clean cloth. This process should be repeated
periodically depending on the local environment.
Beacon Maintenance Precautions
The following precautions should be exercised when handling or storing the
beacon:
▪The beacon should not be exposed to temperatures in excess of
71ºC (160ºF), as the battery life can be reduced by storage in a high
temperature environment.
▪Any situation that could possibly crush or penetrate the case of the
beacon should be avoided.
Battery Maintenance
The shelf life on the ULB-362B beacon is six (6) years. The standard
operational life of the beacon is thirty (30) days of continuous use and it is
recommended that the battery be replaced after every deployment.
When deploying an ULB-362PL/37 power loss beacon on a vehicle, replace
the battery on or before the date stamped on the beacon label.
When replacing the battery on ULB-362B beacon, please follow the chart
below for selecting the proper Battery Kit.
