1. INSTALLATION

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.

Rubber cushion

2.Fix the hanger to the mounting location with tapping screws (6x20).

3.Screw knob bolts into the Loud Hailer.

4.Set the Loud Hailer to the hanger and tighten knob bolts.

1. INSTALLATION

Flush mounting

Requires flush mount kit LH-3020 (Code No. 000-149-112). See the flush mount outline drawing for details.

Contents of flush mount kit

1.Make a cutout in the mounting location referring to flush mount outline drawing.

2.Place the Loud Hailer in the cutout.

3.Fix the two flush mounting plates to the Loud Hailer with screws.

4.Screw the wing nuts on the wing screws.

5.Fix the Loud Hailer with the wing bolts and then tighten the wing nuts.

be connected to the negative t erminal on the DC power source. If the power leads are rev ersed the fuse (inside t he Loud Hailer) will blow.

Intercom speaker (option)

Up to four intercom speakers may be connected to the intercom speaker terminals labeled CAL1-CAL4. Connect eachspeaker to the terminal block according to desired intercom speaker selection. The cable end is prefabricated. Howev er,to meet EMC requ irements 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 j unction box (l ocal supply) . For the connection to the j unction box use cabletype CO-SPEVV-SB-C 0.2X2P (opt ion) an d

fabricate it as below. In this case, theengthl of the cable between the j unction box and an intercom speaker must no be more than 1 m regardless of whether the equipm ent must meet EMC require ments or not.

Distance between loud hailer and intercom speaker is 2-20 m.

Fabrication of speaker cable

1. INSTALLATION

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.

1. INSTALLATION

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.

Output power

The output power may be set for 30 W or 20 W, and the default settings is 30 W. For 20 W output contact a FURUNO agent or dealer for details.

Note: If an external speaker is used it must be capable of handling the rated output power.

Siren mode switch (for LH-3000-CG)

To use the siren mode function, connect a toggle switch whose specifications are as shown below to the burglar alarm terminal.

Do not open the equipment.

Only qualified personnel should work inside the equipment.

3.1 Preventive Maintenance

General checks

Check the following monthly.

???Check all cabling. If damaged, replace.

???Check connections. Retighten if necessary.

???Measure the input voltage to be sure it is within the rated voltage (13.6 VDC ??20%).

Cleaning

Dust or dirt should be removed from exterior surfaces with a soft, dry cloth. Do not use chemical-based cleaners to clean the Loud Hailer ??? they can remove paint and markings.

3. MAINTENANCE, TROUBLESHOOTING

3.2 Replacing the Fuse

The 6A fuse inside the Loud Hailer protects it from reverse polarity and equipment fault. If the power cannot be turned on, the fuse may have blown. Have a qualified technician check the fuse.

WARNING

Use the proper fuse.

Use of a wrong fuse can result in damage to the equipment or cause fire.

3.3 Troubleshooting

Below are simple troubleshooting procedures which the user may follow to try to restore normal operation. If normal operation cannot be restored, do not attempt to check inside any unit. Any repair work is best left to a qualified technician.
