The 295HFS4, although technologically advanced, is simple to
install. An aftermarket center console is recommended for the
mounting location. This not only allows the driver to reach the
controls easily, but also keeps the unit safely out of the path of
the vehicle’s SRS air bag. Follow the console manufacturer’s
instructions for mounting information. If a console-type mount is
not possible, the unit is specially designed for dash (or panel)
mounting. WARNING: Mounting will require drilling. Make sure
that no vehicle components behind the mounting area will be
damaged. If damage is possible, select another location.
INSTALLATION / Amplifier:
1. From inside the trunk, position the amplifier against the ver-
tical trunk wall behind the rear seat and mark off the 4
mounting holes using a scribe or other suitable tool. Be sure
that the remote amplifier fits properly and does not interfere
with any parts of the trunk or seat back.
2. Carefully drill the indicated holes using an appropriately
sized drill bit.
3. Using the supplied sheet metal screws, secure the remote
amplifier to the vertical trunk wall.

SI-TEST is a diagnostic feature
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 its 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 ultrahigh frequency tone through each speaker. Although these
tones are inaudible to humans, be sure that there is nobody

DIAGNOSTIC INDICATORS: This unit has two diagnostic indicators on the front panel which are used to indicate fault conditions with your siren system. The table on the next page lists
the type of fault and the indicators response. If the indicator is
on steady while a tone is in use, this implies that there is no
fault with the associated speaker output.

Rotary Switch Operations
RAD (Radio Repeat) - When the rotary knob is in the RAD posi-
tion, any signal that is received by the vehicle’s two-way radio will
be simultaneously broadcast over the vehicle’s loudspeaker (unit
must be connected to the two-way radio as outlined in this manual).
With the Rotary Switch in this Position:
• Pressing the MAN button will result in SI TEST®.
• Activating the HORN RING input results in the AIRHORN tone
until the HORN RING input is released.
• Activating the AUX ENABLE input has no effect.
PA (Public Address) - When the rotary switch is in this position
the siren is in a standby state where no tones have been
activated, but is waiting for another action to be taken by the operator. This position is often the best choice when public address is
required.
With the Rotary Switch in this Position:
• Pressing the MAN button will result in the AIRHORN tone until
the MAN switch is released.
• Activating the HORN RING input will result in the AIRHORN
tone until the HORN RING input is released.
• Activating the AUX ENABLE input will result in a repeating
WAIL tone.
MAN (Manual Siren) - When the rotary switch is in this position
the siren is in a standby state where no tones have been
activated, but is waiting for another action to be taken by the operator. This position is often the best choice when manual operation
of the siren is desired.
With the Rotary Switch in this Position:
• Pressing the MAN switch will result in a WAIL tone ramping up
to peak frequency and stopping when the MAN switch is
released.
• Activating the HORN RING input will result in a WAIL tone
ramping up to the peek frequency and stopping when the
HORN RING input is released.
• Activating the AUX enable input will result in a repeating WAIL
tone.
HF (Hands-Free Operation) - When the rotary knob is in the HF
position, the siren functions 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 ring (if the vehi-
cle’s horn has been wired to the HORN RING input). 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™ 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.
With the Rotary Switch in this Position:
• Pressing the MAN button will result in the HF cycle as described
above.
• Activating the HORN RING input will result in the HF cycle as
described above.
• Activating the AUX ENABLE input will start the HF cycle.
WAIL (Wail Tone) - When the rotary knob is in the WAIL position,
a steady, rise and fall tone (wail) is produced.
With the Rotary Switch in this Position:
• Pressing the MAN button will change the siren tone to a yelp
pattern. (a fast rise and fall tone) Pressing the MAN button a
second time returns it back to a wail tone.
• Activating the HORN RING input will change the siren tone to a
yelp pattern. (a fast rise and fall tone) Activating the HORN
RING input again returns it back to a wail tone.
• Activating the AUX ENABLE input has no effect.
YELP (Yelp Tone) - When the rotary knob is in the YELP
position, a fast, rise and fall tone is produced.
With the Rotary Switch in this Position:
• Pressing the MAN button will result in the AIRHORN tone until
the MAN button is released.
• Pressing the HORN RING button will result in the AIRHORN
tone until the HORN RING button is released.
• Activating the AUX ENABLE input has no effect.
