NOTICE
SC-550-10 28 Volt Installation and Operating Instructions Page 3 of 12
The SC-550 Remote Siren Amplifier with integrated Lighting Control is a premium unit designed
for single or dual 100W speaker use. A remote hand control is connected to the amplifier with a
thin cable. A 6-position rotary switch controls the primary operating modes of Phaser, Yelp, Wail,
Manual, Horn and Radio. A siren button and auxiliary siren input is provided for control of the
output tone, depending on the rotary switch setting. An integral microphone provides PA function.
The power switch is combined with the PA volume control. A hole is provided in the amplifier to
adjust Radio volume. A 4-position progressive slide switch controls primary lighting and may
automatically activate the siren. Non-progressive slide switch outputs provided for tailored lighting. Four auxiliary output pushbuttons provide for controlling additional lighting or other devices.
A latching siren cutout input is provided for connection to a door switch, etc. to disable the siren
when exiting the vehicle. An 8-position DIP switch on the amplifier allows selection of various
options: Two-Tone to replace Phaser, Phaser disable, Horn disable , short Manual, and Horn Ring
Cycler 2 (HRC2). Auxiliary siren and cutout input activation polarity along with disabling automatic
siren and slide switch reverse are additional options. The hand control is backlighted with LED's
for night visibility. The siren amplifier utilizes short circuit, high voltage, and reverse polarity protection systems for maximum service life over a wide temperature range. The slide switch and
auxiliary outputs are fused individually.
