The TOMAR model T792HL and T792HL–R preemption emitters are used on authorized vehicles to activate *GTT OPTICOM optical preemption and priority control systems. The T792HL is self-contained, weather resistant, and operates on 12 or 24 VDC vehicle power. The T792HL–R is a remote power supply system designed for installation where available lighthead space is limited. The T792HL–R has all the same features of the T792HL. Configured via optional software, the 3065 can emit any of 10,000 GTT OPTICOM vehicle ID’s in 10 classes of either command (high) or advantage (low) priorities.
