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 provided. 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) should be made with No. 1 8 or larger, stranded, twisted 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 (closed), the alarm function becomes activated and the yelp signal will sound at
the maximum volume through the forward deck hailer horn speaker.
