The Federal Signal Litestak Sound Module is a microprocessor–based 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 tower.

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.
