1. INSTALLATION

1.1 Mounting the Loud Hailer

The Loud Hailer can be mounted on a desktop, on the overhead, on a bulkhead or f lush mounted i n a panel (optional ki t required). Refer to the mounting template (supplied) for installation instructions.

Mounting considerations

When planning the location for t he Loud Hail er, keep in the mind the fol lowing considerations.



Locate the unit where the front panel can be eas ily viewed and operated.



Leave sufficient space at the sides and rear of your uni t for ease of maintenance.



Locate the unit as near to the power sour c e as pos s ible.



The loc ation should be out of direct sunlight because of heat t hat can build up inside the cabinet.



Choose a location not subject to rain and salt spr ay.



Locate the unit well away from sourc es of noise such as motors, al ternators a nd generators.

leads should be increased accordingly to minimize line losses. The wire connected to the positiv e (+) t erminal must be connected to the positiv e terminal on the DC power source, and the wire connected to the negativ e terminal (-) must 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 each speaker 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 cable type CO-SPEVV-SB-C 0.2X2P (opt ion) an d fabricate it as below. In this case, the length 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.

1. INSTALLATION

Hailer horn (local supply)

Mount the hailer horns ( local supply) faci ng away from t he Loud Hailer to prevent feedback. They should also be pointed in the opposite direction of the micr ophone as you are speaking into it. B efore mounting any horn, you should test it with the HAIL feature with the horn in the desired location to check f or s uitability of mount ing location.

Connect horns to the Loud Hailer with cabl e type DPYC-1.5 or equivalent. (See pag e 6 for how to fabricate this cable.) B e s ur e the cable is suitabl e for all-w eather use. The terminat ing point on t he terminal is either FWD or A FT depending on the l oc ation of the speaker.

Burglar alarm (local supply)

The unit can function as a burglar alarm by connecting an exter nal alarm sens or (local supply) to the ALRM ter m inals. The alarm sens or s hould be a “norm ally open switch”. Use cable type TTY CS - 1 or equivalent to connect the sens or. Fabricate the cable as shown below.

When the sens or c onnected to t he ALRM terminal becom es s horted an d the alarm func tion is active, the yelp signal is released at maxi mum vol um e through both hailer hor ns.

Floating ground

The LH-3000 h as a floati ng gr ound. What this means is t hat the heat si nk gr ound is floating and will not ground batteries if t hey are c onnec ted to the s hip’s chass is. To maint ain a floating ground:

1. Use a stereo plug when connecting a 4 ohm speaker to the external speak er plug. Connect i t as shown i n the i llustration below.

Do not use for battery use for ship's earth only

St er eo plug

2. Do not connect any of the output connectors on the rear panel to t he s hip’s ground.

3. SP outputs ar e floati ng and m us t not be connected to either battery or the rear p anel. Use a normal two conductor insulated speaker wire for the horn speaker.

Output power

The output power may be s et for 30 W or 20 W, and the default s ettings is 30 W. For 20 W output contact a FURU NO agent or dealer for details.

Note: I f an external speaker is used it must be capable of handling the rat ed output power.

3. MAINTENANCE, TROUBLESHOOTING

Periodic checks and maint enance are i mportant for maintaining performance. This chapter contai ns m aintenance and troubles hooting instructions to be followed to obtai n optimum performanc e and the longest possi ble life of the equipment.

WARNING

Do not open the equipment.

Only qualified personnel should work inside the equipment.

3.1 Preventive Maintenance

General checks

Check the fol lowi ng m onthly.



Check all c abling. I f damaged, replac e.



Check connect ions. Retighten if necessary.



Measure the input voltage to be sure it is within the rated vol tage (13.6 V DC ±20%).

Cleaning

Dust or dirt should be removed from ext er ior surfaces wi th a soft, dry cloth. Do not us e chemical -bas ed cleaners to clean the Loud Hailer – they c an r em ove paint and m ar k ings.

3. MAINTENANCE, TRO UBLESHO OTING

3.2 Replacing the Fuse

The 6A f use ins ide the Loud Hailer protec ts it from reverse polarity and equipment faul t. If the power c annot be turned on, the fuse may have blown. Have a qualified tec hnician 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 s imple tr oubleshooting pr oc edures which the user m ay follow to try to res tore normal oper ation. If normal operat ion cannot be r es tored, do not attempt to check inside any unit . Any repair work is best left to a qualified techni c ian.
