1 Description

The components of the Opticom™ Infrared System* are the emitter assembly, the optical detector, the phase selector, the interface card, and the system chassis.

The emitter, with an appropriate accessory switch, is mounted on the priority vehicle. It generates a series of optical pulses in the visible and infrared wavelengths. These pulses are sensed by the optical detector mounted at the intersection.

The detector converts the optical energy into electrical signals that are transmitted by cable to the phase selector, interface card, system chassis combination in the traffic controller cabinet.

The phase selector discriminates between valid emitter signals and other sources of optical energy received from the detectors, and activates its outputs in response to valid emitter signals. The phase selector outputs are connected to the traffic controller’s inputs, which request the traffic controller to deliver the desired green for the priority vehicle.

2 Installation

The emitter (Figure 1) is a compact, weather resistant, light-emitting device with optional encoded signal operation intended for use on priority vehicles. The emitter consists of a flash-tube/reflector and housing assembly, a power supply assembly, and the required cables. Accessory switch devices are also available.

Three emitter switch configurations are available as accessories for the emitter.

The M793S is a custom designed, fully enclosed switch assembly consisting of an alternate action push button switch with a positive latch down in the on position, and an indicator light. The mounting bracket is also included. It is intended to be used as an emitter on/off switch mounted in the vehicle operator compartment.

The emitter power supply converts 12 volt DC vehicle battery voltage to the high voltage required for the unit to operate. The installation wiring and internal switch setting determine the unit’s mode of operation. The unit may be installed as a Low priority emitter or as a High priority emitter by simple variations in the installation wiring.

The M592R is identical to the M793S except for the addition of a momentary action push button switch used to implement the automated signal intensity threshold level adjustment (range).

The M793B is a double pole, single throw rocker switch with an indicator light. It is intended for use as an emitter on/off switch in custom switch panels in the vehicle operator compartment (a simple mounting bracket is also included).

An appropriate vehicle class and ID number are determined at the time of installation and are programmed by the setting of the internal code switches.

The emitter, when installed on authorized service and maintenance vehicles, may also be configured to use the automated range setting feature of the phase selector. This feature refines and simplifies intersection setup and maintenance. It also allows the range setting task to be performed by one person.

When the disable feature is installed, it typically uses an existing vehicle switch that switches to battery negative when actuated.

This manual describes emitter, power supply, and switch installations.
