MICROPHONE (PA Override)
The noise-canceling microphone is used for public address operation and overrides any
function when the push-to-talk button on the side of the microphone is pressed.
PA VOL
This control adjusts the PA volume. With the vehicle parked, set the PA
volume to the maximum level with no feedback (squeal).
AUXILIARY INPUT
During installation an auxiliary input may be connected to the horn ring or other switching
device. It provides the same operation as pressing the Siren push-button.
HORN RING CYCLER 2 (HRC2)
During installation, the auxiliary input must be connected and the HRC2 option selected. While
the siren is in standby, tap the horn ring to bring the unit out of standby into Wail tone.
Repeatedly tapping the horn ring will cycle through Wail, Yelp, and Phaser tones. Tapping the
horn ring twice quickly will stop the siren tones and return the unit to standby. Pressing and
holding the horn ring will produce Horn tone until released. Then the siren will return to its
previous siren tone or standby. See OPTION SWITCHES section for further details.
NOTE
: Earlier units with S/N lower than 04190000 have a different version of
HRC
. In this
case the siren tones cycle through Standby, Wail, Yelp, and Phaser. The tone is stopped by
cycling to Standby.
RADIO VOLUME ADJUST
The radio repeat volume level is set using an adjustment on the side
of the amplifier. Set the Selector Switch to the Radio position and
turn on the power. With the radio volume itself set to a normal level,
set the siren radio volume adjust control to the desired level.
CUTOUT INPUT
During installation, a cutout input may be connected to a door switch. It turns off any siren tone
when the door is opened. The siren tone will continue to be cut off even when the door is
closed. Changing any switch or input will restore normal function.
