GENERAL DESCRIPTION The SS650 and LCS652 Siren Amplifiers are designed for single 100W speaker use. Each comes standard with the amplifier unit and switch panel all in one unit. The primary operating modes are Wail, Yelp, Standby, Manual, and Horn. Both the Horn and the Manual Control function will override all other functions, and can be utilized at any time via a rocker switch.
INSTALLER-SELECTABLE OPTIONS The SS650 and LCS652 have Phaser disable, Two-Tone enable, and Auxiliary Horn Polarity options that can be selected during installation. An internal jumper on the printed circuit board inside the amplifier case allows the installer to select these options.
AMPLIFIER COVER REMOVAL If you need to change any of the three options listed above you will need to access the inside of the siren. Remove the two Philips head screws located on the bottom of the unit and the two Philips head screws from the rear, and slide the cover off the back of the unit.
MOUNTING AMPLIFIER The SS650 and LCS652 sirens may be mounted above the dash, below the dash, on a tunnel, or in a rack with the mounting u-bracket provided. Choose a mounting location convenient to the operator and away from any air bag deployment areas.
Power Connector You should also find enclosed with your siren a wiring harness. The SWH-27 wiring harness is used in the SS650. The SWH-83 comes with the LCS652. They come with a 12-port connector using six or nine different colored leads.
