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 vol-
ume 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.
DUAL SWITCH
The Dual switch controls the signal to the two amplifiers. With the switch off, the amplifi-
ers produce a common signal to the speakers. With the switch on, independent siren
signals are produced by each amplifier as follows:
