Wiring Diagram - Whelen Engineering Company 295HF100 Installation Manual

Connecting the Speaker Wires (Orange & Brown)
1. Route the ORANGE and BROWN wires toward the vehicle's siren speakers.
2. Connect the ORANGE wire to the POSITIVE speaker connection on speaker #1.
3. Connect the BROWN wire to the NEGATIVE speaker connection on speaker #1.
Connecting the Horn Relay Wires (White & Grey)
1. Route the WHITE and GREY wires along the factory wire harness and through the firewall at the same point as
the RED and BLACK wires.
2. Locate your vehicle's horn relay and route the WHITE and GREY wires to this. If possible, follow the factory wire
harness to this relay.
3. Locate the wire that connects the vehicle horn to the horn relay.
4. Cut this wire.
5. Connect the WHITE wire to the wire coming from the horn relay.
6. Connect the GREY wire to the wire coming from the horn.
Note:The two (2) remaining BLUE wires are used to connect your two-way radio's external speaker to the
295HF100-series siren for radio re-broadcast. This is an optional connection and does not effect the other
operations of the 295HF100-series siren.
Note:Radio re-broadcast will NOT work with amplified remote speakers! If your remote speaker is amplified
(I.E.: contains a power amp circuit in the speaker assembly), do not enable the radio re-broadcast feature.
1. Locate the two wires that connect the external speaker to the two-way radio.
2. Cut one of these wires and splice one of the BLUE wires into this circuit.
3. Cut the remaining speaker wire and splice the remaining BLUE wire into this circuit.
Connecting the 295HF100 to a Remote Control-Head (Optional):
The 295HF100 may be connected to an existing control-head, such as the Whelen PCC-S9N or equivalent. This is an
optional connection that enables the WAIL tone to be activated through the use of a PCC-S9N button or switch. If this
connection is not chosen, cut the VIOLET wire and cap the remaining stub to prevent accidental grounding of the wire.
