Auxiliary Input: (Violet Wire)
The input is an optional input which will remotely acti-
vate the siren when the auxiliary input wire is connected
to ground. If this feature is needed, connect the auxiliary
input wire to a switch which provides a ground connec-
tion when activated. *Park kill disables this option.
Radio Rebroadcast Input: (Blue Wires)
The 2 – 18ga blue wires on the 12 pin Molex connec-
tor are used to connect your two-way radio’s external
speaker through the siren amplifier and broadcast
through the warning siren speaker and is optional.
Radio Rebroadcast will not work with remotely ampli-
fied speakers due to the signal amplitude being too low.
Locate the 2 wires that connect the external speaker to
the two-way radio. T-tap one blue wire into one of the
external speaker wires. T-tap the other blue wire into
the other external speaker wire. If the blue wires need to
be extended, use a minimum of 20ga. Wire. The Radio
Rebroadcast volume must be adjusted prior to placing
vehicle into service. Set the volume of the two-way
radio to the normal operating level. Press the Radio
Rebroadcast push-button on the siren control panel.
With a small screwdriver, adjust the radio rebroadcast
volume potentiometer located on the back of the siren
amplifier to obtain the proper volume out the speaker.
Turn potentiometer clockwise to increase volume and
counter-clockwise to decrease volume.
Horn Ring Input: (White + White/Black Wire)
The input will allow the operator to control the siren func-
tion by pressing the vehicle horn ring. Refer to program-
ming settings for specific configuration options. Refer
to wiring diagram for details on how to connect the horn
ring input wires to the vehicle’s horn ring wiring. If this
feature is required, the installer needs to determine if the
signal wire from the horn ring is switching the +V or
ground side of the circuit. Refer to programming instruc-
tions on how to set the horn ring polarity on the siren.
Extend the horn ring input wires from the siren amplifier
to the horn ring switch using a minimum of 18ga wire.
The horn ring circuit is capable of handling a maximum of
5 amps and must be fused by the installer.
Siren Speaker Output: (Orange + Orange/Black Wires),
(Green + Green/Black wires) Route the Orange and
Orange/Black wires from the 4 position connector to the
siren speaker. Use a minimum of 18ga. wire to extend
the wires as needed. Connect the Orange wire to the
primary Speaker High wire. Connect the Orange/Black
wire to the primary Speaker Low wire. For ETSA482 only
connect the Green wire to the secondary Speaker High
Wire. Connect the Green/Black wire to the secondary
Speaker Low Wire.
Backlight Input: (Gray Wire)
The input will turn on the backlighting of the control panel
whenever +V is applied to the backlight input wire.
Route the siren amplifier backlight input wire to the
vehicle’s marker light wiring using a minimum of 22ga.
wire to extend as needed. T-tap the backlight input wire
into the vehicle’s marker light +V wire.
Park Kill Input: (Yellow Wire)
The input will silence the siren tone when the input
wire is activated. The input is typically connected
to the transmission neutral safety switch. If this
feature is required, the installer needs to determine
if the signal wire from the neutral safety switch
is switching the +V or ground side of the circuit.
Refer to the programming instructions on how to set
the park kill polarity on the siren. Extend the park
kill input wire from the siren amplifier to the neutral
safety switch using a minimum 22ga. Wire. Park kill
Vin Low is < 5Vdc.
Ignition Input: (Orange/Black Wire)
The input is required to enable the siren system.
Locate the wire on the vehicle which provides +V
when the ignition switch is turned ON. Extend the
ignition input wire as needed using a minimum of
22ga. Wire and tap into the vehicle ignition wire.
