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.
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. 2. 3. 4. 5. Name Type Code No. Flush Mounting Plate TZ7300012A 999-999-025 2 Screw Wing Screw 6X12 SUS304 M4X35 SUS304 999-999-027 999-999-027 2 4 Wing Nut M4 SUS304 999-999-028 4 Make a cutout in the mounting location referring to flush mount outline drawing. Place the Loud Hailer in the cutout.
1. INSTALLATION 1.2 Intercom Speaker (option) Four intercom speakers (maximum) may be connected to get 2-way communications between master station and one or all intercom speakers. For mounting dimensions and fixing instructions, see the outline drawing.
1. INSTALLATION 1.3 Wiring All equipment are terminated at the rear panel of the LH-3000. See the illustration on the next page for how to connect equipment to terminals. Refer to the interconnection diagram for detailed information. Rear panel layout 13.
1. INSTALLATION Wiring The illustration below shows how to connect the power supply. Other equipment are connected similarly. (1) Unfasten screws.

1. INSTALLATION Power connection 77 3 The LH-3000 is intended for Sheath Armor use with a 13.6 VDC power Drain wire fabrication supply. Connect the power L* Armor * Length long enough to reach ground terminal. cable (local supply) to the 15 5 Sheath terminals labeled “13.6V”. φ = 11.7 mm Use cable type DPYC-1.5 or Conductor Cut the sheath. S = 1.5 mm 2 equivalent. Fabricate the φ = 1.56 mm Solder drain wire DPYC-1.5 Sectional view cable as shown below.
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.
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.

2. OPERATION 7 [FUNC] Key Activates automatic and manual warning signals. 8 [LISTEN VOL] Control Adjusts listening volume from the internal speaker; turns power on/off. 9 [HAIL VOL] Control Adjusts output volume from the horn speakers or intercom station speakers.
2. OPERATION 2.3 Adjusting Key Backlighting You may adjust the intensity of the key backlighting cyclically with the [DIM] key, in five levels, including off. 2.4 Adjusting Output Level Turn the [HAIL VOL] control to adjust the output volume from the horn speakers or intercom speakers. Clockwise rotation increases volume; counterclockwise rotation decreases it. 2.
2. OPERATION 2.7 Calling a Specific Intercom Station 1. Press the [Intercom Select] key until the indicator lights on the desired intercom station. After a one-second delay, a short tone sounds from the selected intercom station. 2. Press the PTT switch on the microphone and speak into the microphone. 3. Release the PTT switch to listen for a reply from the selected intercom station. If necessary, adjust listening volume with the [LISTEN VOL] control. 4.
2. OPERATION Manually selecting a calling station 1. Press the [Intercom Select] key until the indicator lights for the desired station. 2. Press the PTT switch on the microphone and answer the call. 3. Release the PTT switch to listen to the intercom station. Adjust listening volume with the [LISTEN VOL] control if necessary. 4. To call another station, select the next station with the [Intercom Select] key. 5.
2. OPERATION 2.10 Sounding Warning Signals Your Loud Hailer has eight different warning signals: two manual and six automatic. The two manual signals, YELP and MAN, are designed to be sounded at each press of the PTT switch on the microphone. The six automatic signals are sounded when the [FUNC] key is operated.
