I. GENERAL.
The UniStat™ (USI) is a TYPE 4X with IP66 rating and the UniStat™ (USIS) is
a TYPE 1 status indicator for indoor use that is compact in size. Each UniStat™ status
indicator contains one base, sleeve, PCB, color LED array, lens, cap, and surface gasket.
The cap and sleeve attach to each end of the lens by twist lock joint. Two screws hold
the base and sleeve together. An O-ring between each module provides a water-tight
and dust-tight seal except for the USIS models which has slots to allow audio to emit
from the unit.
A printed circuit board runs the entire length of the base and sleeve of the
UniStat™ status indicator. The printed circuit board contains a terminal block and
circuitry for the control of a color LED array that has an average life of 100,000 hours.
The terminal block provides connection for two input power lines and eight terminals
for setting the operating modes.
