FEDERAL SIGNAL CORPORATION Litestak ® Status Indicator with LED Lamp Model LSLD Federal Signal’s Litestak® status indicators are vertical columns of light that indicate status in a full 360° radius. LONG LIFE LIGHT SOURCE The Litestak Model LSLD modular indicator light system allows the user to combine up to five interchangeable lamp units with a base power unit. Modules are sold separately for a truly customized indicator. • Available in 24VDC and 120VAC • Five lens colors Light modules come complete with a 100,000-hour LED lamp; LED light output coordinates with the module’s impact-resistant polycarbonate lensing. LED lamps consume less power, operate at a lower temperature, and are remarkably resistant to vibration, which makes them perfect for use in heavy-duty, high vibration applications. • 100,000 hour, vibration-resistant LED lamp • Surface mount and integrated 3/4-inch NPT pipe mount LED lamps are available in five colors: Amber, Blue, Clear, Green or Red. The standard double-contact bayonet base retrofits into any Federal Signal Litestak unit to replace original incandescent lamps. • Indoor use only • Type 1 enclosure An optional Sound Module (Models LSS or LSH–on page 24 and 26) can be added to the top of the Litestak column to create a dual purpose audible/visual status indicating signal. The LSS sound module allows the user to select from 32 tones via a simple dip switch panel. In applications where a single loud tone is all that is necessary, the LSH piezo-electric horn is a perfect audible addition. Litestak is a versatile system that allows the user to select either steady burn or flash. A flasher is included on the 120VAC LSB unit only but can be purchased separately for 24VDC models. The Litestak base unit can be either surface mount or 3/4" NPT pipe mount. Operating Model Voltage Current Mount /4" NPT Pipe/Surface Cap kit included. Includes lens, lamp and light module. * Indicates color: (A) Amber, (B) Blue, (C) Clear, (G) Green or (R) Red 1 2
