GENERAL
This unit is designed for easy operation under the stress associated with high-speed
pursuit. Most siren functions are accessible with one simple motion without
repetitive activation of switches or automatic timed switching that can interfere with
desired operation.
POWER
In order for the siren to function, the power switch
must be in the O N position. When turned on, the
siren may be activated at the operator’s discretion.
SELECTOR SWITCH
The rotary selector switch controls the primary operating function of the siren.
PSHR (Phaser)
- Ultra-fast warble tone used for maximum attention in highly
congested areas.
YELP
- A rapid warble tone used in light to moderately congested areas.
WAIL
- A normal rise-fall tone used on highways and
areas with low traffic or constant traffic flow.
HF (Hands Free)
- Also known as Horn Ring Cycler,
allows the user to cycle through Wail, Yelp, Phaser and
Manual by repeatedly pressing the horn or other switch
connected to the AUX input. Operating any other
switch 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.
MAN (Manual)
- A silent mode that allows push-button
Manual (MAN), push-button Horn, and Public Address
operation. The siren output
winds down
when the
Manual push -button switch is released.
ALERT
- A silent mode that allows push-button Manual (MAN), push-button Horn
and Public Address operation. The siren output
terminates immediately
when the
Manual push -button switch is released.
RADIO
- Also known as Radio Repeat, this function amplifies a radio speaker
input for re-broadcast outside the vehicle through speaker #2. PA is available, but
no siren tones are available in this position.
Please note that for the
SS741MG-TEC the 7 -position
knob functions are reversed.
