2—2

2.4 PLANNING THE INSTALLATION

When planning the location for your RAY 430 to be installed, the following conditions
should be considered to insure dependable and trouble-free operation.

1) The mounting location should be easily accessible to allow easy operation of the
front panel and provide the best viewing angle of the display.

2) There should be adequate ventilation.

3) A sufficient space should be secured behind the unit to allow all cable connections to
the rear panel termina l strip.

4) The mounting place should be located as near to the power source as possible.

5) The selected location should be isolated away from devices that may cause offending
noise or interference, such as motors, steering cables and generators.

6) Generally speaking, the Loudhailer should be protected from prolonged direct
exposure to rain a nd salt spray. It is a good practice to protect t his valuable equipment
as much as possible.

The unit can be conveniently mounted on a chart table, bulkhead, overhead or any other
desired place. (Refer to Figure 2- 1 for typical locations and mounting configurations)

(table top mount) (bulkhead mount) (overhead mount)

Figure 2-3

2.5 ELECTRICAL CONNECTION

Figure 2-4 RAY430 Rear Panel

CAUTION

DO NOT INSTALL THIS RADIO O N VESSELS WITH POSITIVE

GROUND BATTERY SYSTEMS.

2.5.1 DC Power Connections

The RAY 430 is intended for use on vessels with 12 VDC power systems and can
operate as long as the DC supply is regulated between 10.8 and 16 VDC.

The input power connections are made at the terminal strip on the rear of the RAY 430
unit at the terminals labeled “ 13.6V” “+“ and “–“. See Figure 2-8 on page 2-9 for the
exact locations.

2—5

The power leads should nor mally be routed to the ship’ s DC power distribution panel
on larger boats. The RAY430 is fused at 10 amps so connection to a 10 amp or
(maximum of) 15 amp circuit breaker is recommended. On smaller vessels the power
leads may be connected directly to the main battery, isolation switch, or circuit breaker.
For best noise isolation from other shipboard electronics avoid grouping the loudhailer
power connections with radar, radio, or echo sounder power leads together on the same
circuit breaker.

Although the RAY 430’s power consumption is only 65 watts (maximum), if you find
that the power cable leads need to be extended more than 10 feet, the wire size of the
leads should be in-creased accordingly to minimize line losses. For runs of 20-35 feet
#12 AWG is recommended, remember to always solder all connections on all your
power cord additions.

Observe proper polarity! The wire connected to the positive (+) terminal must be
connected to the positive point of the DC power source; The wire connected to the
Negative (—) ter minal of the terminal strip must be connected to the negative point o f
the DC power source. If the power leads are accidentally reversed, the 10 Amp fuse will
blow. If this happens, recheck the polarity of the connections with a voltmeter (VOM)
and, if necessary, reverse the leads for proper connection. Then replace the 10 amp fuse
in the power cord.

2.5.2 Intercom Speaker

Up to four intercom station speakers (optional) can be connected to the intercom
speaker terminals labeled IC1-IC4 on the terminal block. The optional intercom
speakers M95998 are 8 ohms and in-dude “CALL” buttons. Stations 1, 2, 3 and 4,
should be connected to the terminal block accordingly so that they will correspond to
the desired Intercom station selections.

Connect one of the speaker lines to terminal 2, the other line to t he GND terminal (on
the right side of the terminal block). The “call” line should be connected to the terminal

1.

Figure 2-5

2—6

2.5.3 Hailer Horn(s)

The outside hailer horns should be mounted facing away from the display unit to
prevent feedback problems using the universal swivel mount pro vided. High gain audio
amplifier circuits “hailers” are susceptible to high frequency audio oscillations (a.k.a.
feedback). It is highly recommended that be-fore permanently mounting the hailing
horn, that the HAIL feature is tested with the horn in the desired location. This should
be done to ensure optimum performance. Generally speaking the horn should be
mounted as far away as possible and facing away from the RAY 430 base unit. It should
be pointed in the opposite direction of the RAY 430 microphone as you are speaking
into it.

Connection to the horn(s) s hould be made with No. 1 8 or larger, stranded, tw isted pair
copper wire. The two-conductor cable chosen should be suitable for external all-weather
use.

Electrical connections from the deck horn(s) are made on the rear panel terminal strip at
either the FWD or AFT terminal point, depending on the location of the speaker you are
connecting.

For connection to FWD, connect the deck horn to terminals “FWD” 1 and 2. For
connection to AFT, connect the deck horn to terminals “AFT’ 1 and 2.

2.5.4 Connection of Burglar Alarm

By connecting an external alarm sensor using a normally open type of switch (not
supplied) to the ALM terminals, this unit can be used as a burglar alarm in the Fog
ALM mode (burglar alarm).

When the sensor connected at terminals 1 and 2 (AUX) of this terminal block become
shorted (close d), t he alar m funct ion becomes ac tivated a nd the yelp s ignal w ill so und a t
the maximum volume through the forward deck hailer horn speaker.

Figure 2-6

2—7

2.5.5 Remote Microphone

An external microphone connection is located on the rear panel terminal strip. This may
be used if you desire to operate hailing functions from a seconda ry station.

Figure 2-7

2.5.6 Auxiliary Input

Your RAY 430 has been designed to allow you to amplify the audio from your VHF
radiotelephone or any other external audio output (i.e. AM/FM radio, CD player)
through your intercom or deck speaker stations. This external audio input can be
connected at the auxiliary input terminals 1 and 2.

2.5.7 Connection of an External Speaker

In s it uat io ns w here t he ma in unit is d ist an t f ro m t he o pe ra to r a nd t he no ise le ve l is ve r y
high, it may be difficult to hear your RAY 430 clearly. By connecting an external (8
ohms, 5 watts or more) speaker, the sound level can be increased for improved listening
capability. When an external speaker is connected at the external speaker jack, the
internal speaker is automatically disconnected. The connector, a mini phone plug, for
the external speaker is supplied with your RAY 430 for your convenience.

When you press the [FOG] key again this automatic fog signal is selected
“AGROUND” appears in the mode display window and “ FOG 6” appears in t he station
display window.

“FOG 6” will disappear and the station name reappears 1 second after completing th e
selection.
The Fog 6 signal is:
Three bell tones sound at one second intervals, followed b y a rapidly ringing bell tone
for a duration of 5 seconds, followed again by three bell tone sounds at one second
intervals. This is repeated once every minute.

3—11

H. YELP Usage: Coast Guard, Patrol Vessels, etc.
This is a manually activated attention getting alarm signal often used by regulatory
vessels. When the [FOG] key is pressed again Yelp is selected, “Yelp” appears in the
mode display window.

In this mode the horn yelps by pressing the microphone PTT button.

ALARM (Burglar alarm mode)

If an external normally ope n type switch sensor is attached (not supplied) to the ALM
terminal on the rear panel, this unit can operate as a burglar alarm unit.

When the FOG mode key is pressed until “ALARM” appears on the mode display part
and “BURG” appears on the station display window, the burglar alarm mode is enabled.

Within a few seconds “BURG” disappears and forward horn speaker station name
appears. The Burglar alarm signal is a “warble” type of signal similar to the yelp signal.

(WARBLE)

When the Burglar alarm mode is selected, the speaker station is changed to FWD, and
the HAIL volume is set to the maximu m level automat ica lly.

3—12

The alarm itself is not enabled for five minutes after selection. However, in five
minutes, the characters and backlighting on the LCD display window goes out and only
the [FOG] ke y and On/Off & D immer Control (to Off) are op erable on the RAY 43 0.
The RAY 430 will appear to be O FE In this condition the bur glar alar m will only sound
if the ON signal from the external alarm sensor connected to the ALARM is tripped.

Clearing the ALARM mode

To disable the Burglar alarm mode, press the [FOG] key or turn off the RAY 430 by
rotating the On/O ff & Dimmer control knob fully co unterclockwise.

3.3.6 Aux Mode

If the audio output line from a radiotelephone equipment, cassette deck, or
entertainment receiver is connected to the AUX terminals 1 and 2, the output signals of
such units can be amplified through desired speaker stations by the RAY 430.

1. Press the [AUX] mode key which will enable the auxiliary mode.

2. Press the desired speaker station key to select the specific station ([IC 1/2], [IC 3/4]).

3. Adjust the HAIL volume for the desired listening level.
