Emergency Vehicle Preemption Receiver

Also known as Opticom. It allows local emergency vehicles (Fire/ Paramedics) to preempt a traffic signal and turn opposing directions red and the direction of travel for the emergency vehicle green. Local fire departments install these units on traffic signals on major roadways to improve response time to emergencies. The fire department installs a special coded emitter device in their vehicles that trigger the Emergency Vehicle Preemption receiver on the traffic signal, changing the current operation of the signal and allowing the emergency vehicle to have a green light and proceed through the signal. ONLY Fire departments have use/ operation of this device, not even the police departments can use them.
