Operation
Wail/Off/Yelp Button
This is the 3-position button used for
basic operation of the siren. While in
the Wail or Yelp positions the siren will
produce the tone programmed for
that function
(see previous page)
. The
Wail and Yelp functions are defaulted
for the Wail and Yelp tones.
Wail Tone:
A normal rise-fall tone used
on highways and areas with
low traffic or constant traffic
flow.
Yelp Tone:
A rapid warble tone used in
light to moderately
congested areas.
Center Off Position:
(Manual/Standby) - A silent mode that allows momentary
push-button activation of the Manual and Horn functions.
Manual Button
When the unit is powered up with the Wail/Off/Yelp button in the
Off position
(not
producing any siren tones), by default this momentary push button switch provides
a manually rising and falling siren tone while being pressed. The siren output
winds
down
when the Manual momentary switch is released.
With the Wail or Yelp mode selected, pressing the Manual button will “step” the
siren up to the next button’s programmed tone:
(Wail
Yelp
Y
elp Step Up)
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.
(See previous page to program optional tones.)
Horn Button
(SS651MT excluded)
This momentary push button switch provides a simulated air-horn tone while
pressed. It is useful at intersections or in high noise areas. This tone will override all
other siren tones.
(See previous page to program optional tones.)
Auxiliary Function (AUX Terminal) and Hands Free Cycler Mode
Note: Requires connection of the AUX terminal (see page 5).
The AUX terminal is typically connected to the vehicle horn switch. See page 7 to
select positive (+12VDC) or negative (ground) activation.
Normally when the unit is on and in any mode, activating the AUX terminal (i.e.
pressing the vehicle’s horn) will produce the programmed Air Horn tone
(see
previous page to program optional Air Horn tones).
If you enable
Hands Free Cycler mode
using DIP switch #2 as shown on page 7,
pressing the vehicle’s horn continuously for 3 seconds will activate the
Hands Free
Cycler
mode. This mode allows you to use the vehicle’s horn to cycle through the
siren tones associated with the following functions:
(Wail
Yelp
Yelp Step Up
Silent)
