SFGH-100 SIREN & FLASHING LIGHT SYSTEM Installation & Operation

The SFGH-100 is a precision built, full function 100 watt siren system that incorporates both an alternating headlight and grille light flasher in the same unit. The SFGH-100 draws no current unless a function is selected, so there is no battery drain. The Amplifier/Flasher unit mounts in the trunk. Quick connection allows the remotely controlled siren, public address system, air horn, and flashers to be installed easily and quickly.

PLEASE READ THESE INSTRUCTIONS COMPLETELY BEFORE ATTEMPTING THE INSTALLATION

INSTALLATION

Proceed as follows referring to figure (1) on back page.

1.UNPACKING

A.Carefully remove the control head box, power cable, accessory harnesses, and Amplifier/Flasher unit from the shipping carton. Remove the speaker from it’s shipping carton.

2.MOUNTING

A.The Amplifier/Flasher unit should be located in the trunk on the same side of the vehicle as the battery. Preferred locations are under the rear deck or on the rear seat supports. Mount the unit using 4 sheet metal screws. Be careful that the screws don’t intrude into the passenger compartment. Keep in mind the location of connectors P1, P2, and P3 and where their cables will run. CAUTION: The transistor heatsinks must NOT touch ground. If possible, the unit should be mounted to a metal surface for adequate ventilation and heat dissipation.

B.Find a suitable location for speaker mounting, away from heat, moving parts, and as protected as possible. On some vehicles this can be in front of the radiator, on others behind the bumper, or between the tire and bumper. Mount the speaker securely, IT IS HEAVY. Use at least 1/4 x 20 bolts & nuts. Route the plug-in connector into the engine compartment.

3.POWER CABLE INSTALLATION

A.The power cable included in the SFGH-100 system is equipped with a 12 pin socket on one end (P2) and butt connectors for the engine compartment, on the other.

B.Find a large grommet, or drill a 1 1/4” hole in the vehicle’s firewall on the same side as the battery. If a hole was drilled use a grommet or snap bushing to protect the cable. Route the cable to the trunk, leaving the WHITE sense wire in the front seat area for later connec- tion. Plug the power cable into its’ mating connector (P2) on the Amplifier/Flasher unit.

Be sure to leave enough slack in the cable at the connector so the plug can’t pull out.

C.The black ground wire should be connected to the vehicles chassis with a sheet metal screw and star type lock washer under the terminal. Make sure it is a good clean connection.

D.Route the speaker wire to the brown and blue/black wires in the power cable and butt connect them together.
