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. Page 14 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. 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. The two manual signals, YELP and MAN, are designed to be sounded at each press of the PTT switch on the microphone. Only the horn speakers sound warning signals and the volume is automatically set to maximum when sounding warning signals. Page 21 2.
