Sound Module

Model LSS

The Federal Signal Litestak®Sound Module is a microprocessor­based audible signaling device. The model LSS can be used as a
stand-alone audible device or combined with the Federal Signal
Litestak light modules to create an audible/visual signal.

The sound module contains a microprocessor-based tone generator
and an integrated speaker which produces one of 18 tones. Select
tones by setting five, 2-position DIP-switches. The sound module
can work as a stand-alone audible signal when plugged into the
Model LSBS Low Profile Surface Mount Base or Model LSB Pipe
Mount Base.

The Model LSS can be combined with any Litestak light module
configuration of up to four colors. Controlling the sound module
is done via the wires normally used for the clear light module. The
sound module always occupies the top module position in a
Litestak

Ideal applications for the LSS include environments where the
ambient noise is not extreme – assembly lines, conveyor systems,
automated lines, instrument panels and workshops.

LSS is UL Listed and CSA Certified.

Federal Signal’s Litestak Sound Module allows the user to add a
distinctive audible signal to a Litestak Status Indicator.
