Operating the WS295HFS1 Controls:
Power Switch
This switch has two positions: Down (WS295HFS1 - Off) and Up
(WS295HFS1 - On). When this switch is in the Off position, the WS295HFS
will not function. When the switch is in the On position the siren is functional
and may be activated at the operator’s discretion.
NOTE: If the WS295HFS1
is connected to the vehicle’s horn ring circuit, the vehicle horn is disabled
when the WS295HFS1 power switch is in the ON position.
MAN Button
The Manual button generates a variety of tones, depending on what position
the Rotary knob is in. For further explanation of this button’s function, refer to
the Rotary knob section of this manual.
Rotary Switch
The Rotary Knob controls the siren and PA (Public Address) functions of the
WS295HFS1. There are 7 positions that may be selected. Each position and
it’s function is outlined below:
RAD (Radio Repeat)
- When the rotary knob is in the RAD position, any signal that is received by the vehicle’s two-
way radio will be simultaneously broadcast over the vehicle’s loudspeaker (the WS295HFS1 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 operational. Messages
may be broadcast over the vehicle’s loudspeaker when the WS295HFS1 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 WS295HFS1).
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
WS295HFS1). Please note that the WS295HFS1 microphone will override the siren function.
HF (Hands Free Operation)
- When the rotary knob is in the HF position, the siren functions of the WS295HFS1 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 vehi-
cle’s steering wheel horn button (if the vehicle’s horn has been wired to the WS295HFS1). 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 vehicle’s horn has been
wired to the WS295HFS1), 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 WS295HFS1 microphone will override the siren function.
