1. GENERAL INFORMATION
The STANDARD HORIZON VLH-3000A is a marine Loud Hailer that operates as a multifunction unit. It has three modes:
Hail/Listen-Back
m
Intercom
m
Automatic Signalling
m
In the Hail/Listen-Back mode, the Loud Hailer can send amplied audio
signals to a PA horn and then listen back for signals coming in from the
PA horn.
In the Intercom mode, the Load Hailer can have private conversations
with up to two MLS-300i intercom stations.
In the Automatic Signaling mode, the Loud Hailer can send different
kinds of signals used mostly to alert nearby vessels to the presence and
approximate position, and to indicate the vessel’s status or maneuverability limitation.
Your Loud Hailer requires 13.8 VDC (±20 %) power input. The VLH3000A maximum PA speaker output is 30W.

4. INSTALLATION
4.1 Optional MMB-84 Flush Mount Installation
1. To assist in ush mounting, a template has been included. Use this
template to nd the mounting location.
2. Use the template to mark the location where the rectangular hole is to
be cut. Conrm the space behind the dash or panel is deep enough to
accommodate the VLH-3000A (at least 4.5 inches or 11.5 cm deep).
There should be at least 1/2 inch (1.3 cm) between the VLH-3000A’s
heatsink and any wiring, cables or structures.
3. Cut out the rectangular hole and insert the VLH-3000A.
4. Fasten the brackets to the sides of the VLH-3000A with the lock
washer nut combination; so that the mounting screw base faces the
mounting surface (see Figure 1).
5. Turn the adjusting screw to adjust the tension so that the VLH-3000A
is tight against the mounting surface.

NOTE
The terminal strip is not waterproof. Care needs to be taken when
installing so it is not directly exposed to the elements.

VLH-3000A
Page 7
1. Use the supplied Power Cord assembly for power connection. Connect the red wire to the “Positive (+)” terminal, and the black wire to
the “Negative (–)” terminal of the power source.
CAUTION
Reverse polarity connections will damage the VLH-3000A.
2. Use #22 AWG (or larger) stranded, plastic-jacketed wire to connect
the PA Horns (“FWD” and “AFT” terminals) and Intercom Speakers
(“IC1” and “IC2” terminals).
3. An external 4-Ohm 6 W speaker may be connected (“EXT SP” terminal), if desired.
4. For the PA Horn, it is recommended that a 4-Ohm 30 W horn speaker
be used. Also note that an 8-Ohm speaker may be used, but the loudness will be reduced.
5. The VLH-3000A can use the optional MLS-300i Intercom Speaker.
This is connected to any of the Intercom terminals (“IC1” or “IC2”).
6. See Detail “A” in Figure 2, If a 2-wire speaker (such as a MLS-300
External Speaker) is connected to the Intercom terminals (“IC1” or
“IC2”), the positive wire should be connected to the center terminal
and negative wire should be connected to the left-hand terminal. Do
not connect the any wire to the right-hand terminal! If you connect one
of the wires of a 2-wire speaker to a right-hand terminal, the speaker
will beep continuously when turned on.
7. Put the supplied Protection Cover to the terminals to avoid a short circuit.
