UniStat® LED Status Indicators

The UniStat

®

is a LED, multi-color, single-high status indicator.

This status indicator can produce either three colors (Amber, Green and Red) or four colors (Amber, Blue, Green and Red)
from a single light source.

®

The UniStat offers a choice of four integrated flash patterns – steady burn, slow flash, strobe flash and SimuStrobe

.
SimuStrobe simulates the attention-getting flash rate of a strobe light but with a much more color-rich output. The user
can choose a total of 12 possible flash/color combinations in the tri-color models and 16 in the quad-color models.

When the application calls for an increased sense of urgency, specify model USIS with an integrated piezo sounder.
Producing 60 dBa @ 10 feet, the USIS is the ideal attention getter in process control applications.

Each model arrives pre-assembled and ready to surface mount or 3/4-inch NPT pipe mount. Options for the UniStat
include pipe mount extensions (4",16", and 32"), a wall mount bracket and a tulip mount base.
