1 GENERAL INFORMATION
The STANDARD HORIZON VLH-3000 is a marine Loud Hailer that operates as a multifunction unit. It has three modes:
Hail/Listen-Back
Intercom
Automatic Signalling
In the Hail/Listen-Back mode, the Loud Hailer can send amplified 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 VLH-3000
maximum PA speaker output is 30W.

4 INSTALLATION
4.1 Optional MMB-84 Flush Mount Installation
1. To assist in flush mounting, a template has been included. Use this template to find the mounting location.
2. Use the template to mark the location where the rectangular hole is to be
cut. Confirm the space behind the dash or panel is deep enough to accommodate the VLH-3000 (at least 4.5 inches or 11.5 cm deep).
There should be at least 1/2 inch (1.3 cm) between the VLH-3000’s
heatsink and any wiring, cables or structures.
3. Cut out the rectangular hole and insert the VLH-3000.
4. Fasten the brackets to the sides of the VLH-3000 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-3000 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-3000Page 6
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-3000
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-3000 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.
