Status Indicator
with LED Lamp
Model LSLD
Federal Signal’s Litestak®status indicators are vertical columns of
light that indicate the status of a machine’s operating process in a
full 360° radius.
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.
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.
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
An optional Sound Module (Models LSS or LSH) 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
replace original incandescent lamps.
