•Eight internationally accepted warning signals can be selected for automatic operation for
a variety of different maritime situations alerting nearby vessels of your presence and
status in low visibility conditions.
•Four intercom stations (speakers) may be connected to get 2-way communications
between master station and one or all intercom stations.
•LED indicators alert you to equipment status.
•Keys are backlit for nighttime operation.
•Smartly designed and intuitive front panel for ease of operation.
•An auxiliary audio input allows transmission of music or other external audio signals (from

NOTICE
Do not apply paint, anti-corrosive sealant
or contact spray to coating or plastic
parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.
1.1 Mounting the Loud Hailer
The Loud Hailer can be mounted on a desktop, on the overhead, on a bulkhead or flush
mounted in a panel (optional kit required). Refer to the mounting template (supplied) for
installation instructions.
Mounting considerations
When planning the location for the Loud Hailer, keep in the mind the following
considerations.
• Locate the unit where the front panel can be easily viewed and operated.
• Leave sufficient space at the sides and rear of your unit for ease of maintenance.
• Locate the unit as near to the power source as possible.
• The location should be out of direct sunlight because of heat that can build up inside the
cabinet.
• Choose a location not subject to rain and salt spray.
• Locate the unit well away from sources of noise such as motors, alternators and
generators.
Mounting procedure
Desktop, bulkhead, overhead mounting
1. Attach rubber cushions (supplied) to the body of the Loud Hailer. Position the cushions
so they locate across from the bottom of the slot in the hanger regardless of mounting
method.

Power connection
The LH-3000 is intended for
use with a 13.6 VDC power
supply. Connect the power
cable (local supply) to the
terminals labeled “13.6V”.
Use cable type DPYC-1.5 or
equivalent. Fabricate the
cable as shown right.For
longer runs the wire size of
leads should be increased
accordingly to minimize line
losses. The wire connected to the positive (+) terminal must be connected to the positive
terminal on the DC power source, and the wire connected to the negative terminal (-) must
be connected to the negative terminal on the DC power source. If the power leads are
reversed the fuse (inside the Loud Hailer) will blow.
Intercom speaker (option)
Up to four intercom speakers may be connected to the intercom speaker terminals labeled
CAL1-CAL4. Connect each speaker to the terminal block according to desired intercom
speaker selection. The cable end is prefabricated. However, to meet EMC requirements the
length of the cable must be less than 1 m. If the distance between the Loud Hailer and
intercom speaker is greater than 2 m (max. 20 m), use a junction box (local supply). For the
connection to the junction box use cable type CO-SPEVV-SB-C 0.2X2P (option) and
fabricate it as below. In this case, the length of the cable between the junction box and an
intercom speaker must no be more than 1 m regardless of whether the equipment must
meet EMC requirements or not.

Hailer horn (local supply)
Mount the hailer horns (local supply) facing away from the Loud Hailer to prevent feedback.
They should also be pointed in the opposite direction of the microphone as you are
speaking into it. Before mounting any horn, you should test it with the HAIL feature with the
horn in the desired location to check for suitability of mounting location.
Connect horns to the Loud Hailer with cable type DPYC-1.5 or equivalent. (See page 6 for
how to fabricate this cable.) Be sure the cable is suitable for all-weather use. The
terminating point on the terminal is either FWD or AFT depending on the location of the
speaker.
Burglar alarm (local supply)
The unit can function as a burglar alarm by connecting an external alarm sensor (local
supply) to the ALRM terminals. The alarm sensor should be a “normally open switch”. Use
cable type TTYCS-1 or equivalent to connect the sensor. Fabricate the cable as shown
below.
When the sensor connected to the ALRM terminal becomes shorted and the alarm function
is active, the yelp signal is released at maximum volume through both hailer horns.

Floating ground
The LH-3000 has a floating ground. What this means is that the heat sink ground is floating
and will not ground batteries if they are connected to the ship’s chassis. To maintain a
floating ground:
1. Use a stereo plug when connecting a 4 ohm speaker to the external speaker plug.
Connect it as shown in the illustration below.
Do not use for battery -
use for ship's earth only
Stereo plug
2. Do not connect any of the output connectors on the rear panel to the ship’s ground.
3. SP outputs are floating and must not be connected to either battery or the rear panel.
Use a normal two conductor insulated speaker wire for the horn speaker.
Siren mode switch (for LH-3000-CG)
