RAD (Radio Repeat)
- When the rotary knob is in the RAD position, any signal that is received by the vehi-
cle’s two-way radio will be simultaneously broadcast over the vehicle’s loudspeaker (the 295HFS6 must be
connected to the two-way radio as outlined in this manual). This function overrides any other siren function.
PA (Public Address)
- When the rotary knob is in the PA position, public address functions are opera-
tional. Messages may be broadcast over the vehicle’s loudspeaker when the 295HFS6 microphone is in
use. The volume level of PA transmissions is controlled by the volume knob. If the Manual button is
pressed while the rotary knob is in this position, an “air horn” siren tone will be generated by your vehicle’s
loudspeaker. This tone is generated until the Manual button is released. The “air horn” may also be
generated by pressing the vehicle’s steering wheel horn button (if the vehicle’s horn has been wired to the
295HFS6).
MAN (Manual Siren)
- When the rotary knob is in the MAN position, pressing the Manual button generates
a tone that rises in pitch to a pre-set level. This tone is generated for as long as the Manual button is
pressed. The same tone may be generated by pressing the vehicle’s steering wheel horn button (if the
vehicle’s horn has been wired to the 295HFS6). Please note that the 295HFS6 microphone will override
the siren function. The MAN button is also used to activate the SI-TEST
®
cycle. See the SI-TEST
®
section
on the following page for details on this important function.
HF (Hands Free Operation)
- When the rotary knob is in the HF position, the siren functions of the
295HFS6 are placed in a stand-by mode. Siren tones are activated by a single “tap” on the MAN button or
a single “tap” on the vehicle’s steering wheel horn button (if the vehicle’s horn has been wired to the
295HFS6). The first “tap” produces a “Wail” tone (a steady, rise and fall tone). A second “tap” produces a
“Yelp” tone (a fast, rise and fall tone). A third “tap” produces a “Piercer
TM
” tone (an extremely fast, rise and
fall tone). The next “tap” returns the siren to a “Wail” tone and the cycle repeats itself. Two quick, succes-
sive “taps” will stop the siren.
WAIL (Wail Tone)
- When the rotary knob is in the WAIL position, a steady, rise and fall tone is produced.
A single “tap” on the MAN button or a single “tap” on the vehicle’s steering wheel horn button (if the vehi-
cle’s horn has been wired to the 295HFS6), changes the siren tone to a “Yelp” pattern (a fast, rise and fall
tone). A second “tap”, and the siren returns to a “Wail” tone. Please note that the 295HFS6 microphone will
override the siren function.
YELP (Yelp Tone)
- When the rotary knob is in the YELP position, a fast, rise and fall tone is produced.
Pressing the MAN button or the vehicle’s steering wheel horn button (if the vehicle’s horn has been wired to
the 295HFS6), changes the siren tone to a simulated air horn tone for as long as the button is pressed.
Releasing the button causes the siren to return to the Yelp tone. Please note that the 295HFS6 microphone
will override the siren function.
PIER (Piercer
TM
Tone)
- (NOTE: Some models may have a Hi/Lo tone instead of the Piercer
TM
tone) When
the rotary knob is in the PIER/Hi-Lo position, an extremely fast, rise and fall tone (alternating high and low
tones for Hi-Lo) is produced. Pressing the MAN button or a single “tap” on the vehicle’s steering wheel horn
button (if the vehicle’s horn has been wired to the 295HFS6), changes the siren tone to a simulated air horn
tone for as long as the button is pressed. Releasing the button causes the siren to return to the “Piercer
TM
”
(Hi-Lo) tone. Please note that the 295HFS6 microphone will override the siren function.
SI-TEST
®
SI-TEST
®
is a diagnostic feature of the 295HFS6 and allows the
operator to confirm the proper operation of the siren speakers
connected to the 295HFS6 without activating an audible siren
tone. To initiate the SI-TEST
®
cycle, set the rotary knob to the RAD
position. Now press and hold the MAN button for at least 5
seconds. As the siren is tested, its diagnostic indicator will turn on
if no problems are detected. If the indicator doesn’t light, a problem
with either the siren or it’s connectors has been detected. Check
the wire connections for the failed speaker and repeat SI-TEST
®
. If the speaker fails the test again, have
the siren itself inspected by a qualified technician.
NOTE:
Installed speakers are tested by generating an
ultra-high frequency tone through each speaker. Although these tones are inaudible to humans, be sure
that there is nobody within at least 5 feet of the vehicle’s speakers when SI-TEST
®
is running.
