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.) Be sure the cable is suitable for all-weather use. The
terminating point on the terminal is either FWD or AFT depending on the location of the
speaker.
Burglar alarm (local supply)
The unit can function as a burglar alarm by connecting an external alarm sensor (local
supply) to the ALRM terminals. The alarm sensor should be a “normally open switch”. Use
cable type TTYCS-1 or equivalent to connect the sensor. Fabricate the cable as shown
below.
When the sensor connected to the ALRM terminal becomes shorted and the alarm function
is active, the yelp signal is released at maximum volume through both hailer horns.
