RADIO VOLUME
The radio repeat volume level is set
using an adjustment inside the case
just behind the PA volume control.
Press on the rear of the case to
open the unit, then set the Selector
Switch to the Radio position and turn
on the power. With the radio volume
set to normal level, adjust the siren
radio repeat control to the desired
level. Turn off power and press the
unit back into the case.
OVERRIDE FUNCTIONS
In addition to PA Override, two other override functions are available and controlled
by the Siren button or auxiliary input.
Horn Override - With the Selector Switch in the Phaser, Yelp or Horn positions the
Siren button or auxiliary input activates a simulated air-horn tone. This can optionally
be disabled.
Yelp Override - With the Selector Switch in the Wail position, pressing the Siren but-
ton or activating the auxiliary input toggles between the Wail and Yelp function.
HORN RING CYCLER (Optional)
During installation, the auxiliary input may be connected to the horn ring or other
switching device, and the HRC option selected. With the Selector Switch set to the
Horn position, the horn ring or Siren button can be tapped repeatedly to select the
Wail, Yelp, Phaser and Standby tones or modes in succession. Pressing and holding
the horn ring or Siren button operates the Horn tone without changing the basic tone
selection.
SHORT MANUAL (Optional)
Under normal operation in the Manual position, when the Siren button is pressed the
siren tone gradually increases to a peak level, then gradually falls when the button is
released. This option eliminates the gradual fall of the tone upon button release,
stopping tone output immediately.
