ELECTRICAL CONNECTIONS
Connections are made using pressure terminal connectors. Legends on the unit identify each terminal function. Attach leads by stripping 3/8", inserting into connector and clamp by tightening screw. Make sure the screw is tight and the wire can't be pulled out. Failure to adequately tighten the screw can result in improper operation or burning the connector and wire.
Positive Supply: Due to the high current nature of this unit, an appropriate supply line is required. In addition to the high current delivered to devices on the out- puts, the siren amplifier will require peak currents up to 50 amps for ade- quate short circuit protection and reliable operation. The preferred source is directly at the vehicle battery.
Negative Supply: The negative supply line is for the siren amplifier. The siren amplifier will require peak currents up to 50 amps for adequate short circuit protection and reliable operation. The preferred source is directly at the vehicle bat- tery.
Speaker:Both connections must be used. Two speakers may be connected in par- allel. Observe polarity (phasing) for maximum sound output.
Radio (Optional): Both connections must be used. The input is isolated and polarity is not important. May need to adjust RADIO VOLUME on side of amplifier.
Auxiliary Siren
(Optional): The auxiliary siren input allows activation of the Siren button with an exter- nal source. The OPTION SWITCH determines polarity of activation.
