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 295HFS5 must be 
connected to the two-way radio as outlined in manual). This function overrides any other siren function.

PA (Public Address)

 - When the rotary knob is in the PA position, public address functions are

operational. Messages may be broadcast over the vehicle’s loudspeaker when the 295HFS5 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 gener-
ated by pressing the vehicle’s steering wheel horn button (if the vehicle’s horn has been wired to the siren).

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 295HFS5). Please note that the 295HFS5 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 

295HFS5 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 siren). 
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, successive “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 295HFS5), 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 295HFS5 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 295HFS5), 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 295HFS5 micro-
phone 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 295HFS5), 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 295HFS5 microphone will override the siren function.

SI-TEST

®

SI-TEST

®

 is a diagnostic feature of the 295HFS5 and allows the

operator to confirm the proper operation of the siren speakers
connected to the 295HFS5 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 speaker or it’s connectors has been detected. Check the wire connections for the failed speaker 
and repeat the 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.
