ELECTRICAL CONNECTIONS

Disconnect vehicle battery before making any electrical connections.

Electrical connections to the unit are made using a removable terminal block plug and screw terminals located on the amplifier. A label on the unit identifies each terminal function. Install the plug on the unit before wiring. If the unit needs service the plug can be easily removed without unwiring. The power supply of the unit must be capable of delivering peak currents up to 50 amps for adequate short circuit protection and reliable operation. The preferred source is directly at the vehicle battery. The amplifier is fused. Attach leads by stripping 3/8", inserting into plug 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.

Wire Size and Termination - The diagram shows the minimum wire size used for each connection, along with recommended lead color. If the wire is longer than 10 ft. use the next larger wire size. Use only high quality crimp connectors for installation on the vehicle.

Enable Input Connection (ORG lead on wiring diagram next page) - This is NOT the same as the main power connection. The enable input is like a power switch for the unit. When there is positive power at this connection, the unit is powered up and ready to function. When power is removed, the unit is not powered up and will not drain current from the battery. Connect to a positive circuit controlled by the vehicle ignition switch, usually a terminal at the vehicle fuse panel. The required current is low (15mA typ.).

For SC-1022:

The Enable Input must be connected.

For SC-1002 and SC-1012:

The Enable Input is optional.

If it is not desired to wire the Enable Input, set the Instant ON DIP switch as described under INSTALLER SELECTABLE OPTIONS. The unit will instantly turn on when a switch on the face of the unit or the control panel is activated. This includes LT1 and LT2 switches. When all switches are deactivated, the unit will turn off. Without the enable input, the Manual siren tone will stop immediately. LT1 or LT2 switch may be used as power switch for the unit instead of Enable Input.

Auxiliary Input Connection (Optional) - A momentary input typically connected to the horn ring of the vehicle or other switch. See OPERATION section for auxiliary input functions.

NOTE: Permanent disconnection of the vehicle horn is NOT recommended.

The auxiliary input may be activated with positive or negative voltage. See Auxiliary Polarity under INSTALLER SELECTABLE OPTIONS section for proper activation polarity. Input current is 1 to 20 mA.

Aux Input for SC-1002 and SC-1012:

The unit must be turned on for the Auxiliary Input to function. This is accomplished with either the siren controls or Enable Input.
