Operation
Please note that for the SS741MG-TEC the 7-position knob functions are reversed.
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 ON position. When turned on, the siren may
be activated at the operator’s discretion.
General
Selector Switch
The rotary selector switch controls the primary operating function of the siren.
PHSR
- Ultra-fast changing tone used for maximum attention.
YELP
- A rapidly changing tone used in congested areas.
WAIL
- A slower changing tone used on highways.
HF
- Hands Free - A silent standby mode also
known as Horn Ring Cycler. Allows the user
to cycle through the tones programmed for
the WAIL, YELP, PHSR, and OFF by repeatedly
pressing the horn or other switch connected
to the AUX input. Changing the rotary knob
to any other mode will resume normal siren
operation.
MAN
- A silent standby mode that allows push-button
Manual, push-button Horn, and Public Address
operation. The siren output winds down when
the MAN button is released.
ALERT
- A silent standby mode that allows push-button Manual, push-button Horn
and Public Address operation. The siren output terminates immediately
when the MAN button is released.
RADIO
- Also known as Radio Repeat, this function amplifies a
two-way
radio
speaker input for re-broadcast outside the vehicle through speaker #2.
The PA remains functional, but no siren tones are available in this position.
Please note that for the
SS741MG-TEC the 7-position
knob functions are reversed.
