The –TC model color LED array can be set to operate in one of 4 modes while
illuminating one of three colors; amber, green or red. Three terminals are used to
select the illuminated color.
The –QC model color LED array can be set to operate in one of 4 modes while
illuminating one of four colors; blue, amber, green or red. Four terminals are used to
select the illuminated color.
In addition to color selection there are two terminals which are used to select the
slow flash, Simu Strobe™, strobe flash, or steady-burn mode. The desired selection is
accomplished by contact closure between the appropriate control pin to the common
signal pin ("SEL") on the terminal block. An additional terminal provides sound option
for the USIS models.
Table 1 identifies the terminal connections and operating modes for the UniStat™
-TC and -QC models.
