-20-
(Operation CONT’D)
The seven push buttons
across the middle of the
control head allow full
siren operation. When
not activated, these
buttons are backlit in green for nighttime viewing. When activated, an audible
beep is heard, and the backlighting turns red.
MAN (Manual )
In stand-by (no tone) or in the Hands Free Mode, this momentary push
button switch provides a manually activated Wail siren tone while being
pressed. With the Wail, Yelp, or Phaser mode selected, this switch provides
a generally quicker changing tone. (See tables on next page). These quicker
tones are used to momentarily alert motorists at intersections and very highly
congested areas. Pressing the button once changes to the next faster tone.
Pressing the manual button again, reverts the siren back to the original tone.
Optional configuration allows the replacement of the Phaser tone with Two-
Tone, or the disabling the Phaser tone entirely. These options are selected
during installation and may be governed by State or Local laws.
(See page 5
of the INSTALLER-SELECTABLE OPTIONS section for jumper details.)
.
HORN (Air Horn)
This momentary push button switch provides a simulated air-horn tone while
pressed. This can be used to either replace, or to supplement the normal
vehicle horn and is useful at intersections or in high noise areas. This tone
will override all other siren tones.
HF (Hands Free)
Also known as Horn Ring Cycler, allows the user to cycle through Wail,
Yelp, Phaser, and Standby by repeatedly pressing the horn or other switch
connected to the AUX input. Operating any other mode resumes normal
operation. Please note that this mode disables the Manual (MAN) push
button selection when a Wail, Yelp, or Phaser tone is cycled to.
WAIL
A normal rise-fall tone used on highways and areas with low traffic or
constant traffic flow.
YELP
A rapid warble tone used in light to moderately congested areas.
PHSR (Phaser)
Ultra-fast warble one used for maximum attention in highly congested areas.

RADIO
Also known as Radio Repeat, this function amplifies a radio speaker input
for re-broadcast outside the vehicle through the siren speaker(s). PA is
available, but no siren tones are available in this position
