Categories: AVI, Parking Controls, Traffic Controls

Product Type: AVI Receiver

The Diablo Controls Hands-Free Automatic Vehicle Identifier System

Consists of an AVI Transmitter and an AVI Receiver

The AVI System has many different uses and applications including Emergency Vehicle Access, Mass Transit, Shuttle Buses, Private Homeowner Access, Trucking Companies, Manufacturing Facilities, Fork Lifts, Airport Access, Rail Cars, and many other types of applications.

Depending on the type of application, the user can choose to have the AVI System “Hands Free” or manual.

The AVI system is configured and tested at the factory, providing a true “Plug & Play” environment. All codes are documented and saved at the factory to eliminate duplicate codes being used by existing customers. The AVI system has Multiple Code capability allowing for greater versatility and security.

The AVI Transmitter is potted in a thermal epoxy compound and is mounted to the underside of a fire apparatus, police car, bus, light-rail train, and many other vehicles. When the vehicle approaches a gated area, the code is received by a loop buried in the ground ahead of the gate or barrier.

The receiver is the “smarts” of the system. It receives the coded message coming from the transmitter. If the transmitted code matches the pre-programmed code stored in the receiver, a relay contact is closed and a red LED is illuminated indicating a valid code is being received. This signal is then passed on to a gate controller, which automatically opens the gate or performs some other security function.

Over 19,000 codes to choose from
Can be programmed to accept up to 4 different codes
Operates on 8 to 35 volts DC
Can be field programmable with the “Learn” pushbutton
No switches to set
Small profile, perfect for many installations
Responds to transmitters made by other manufacturers

The Diablo Controls AVI system consists of a receiver and transmitter. The transmitter is mounted to the underside of a fire engine, police car or other vehicle. The transmitter continuously transmits a coded signal when power is applied. When this vehicle approaches a gated area, the code is received by a loop buried in the ground ahead of the gate or barrier and passed on to the receiver. The receiver unit is the “smarts” of the system. If the transmitted code matches any of the pre-programmed codes stored in the receiver, a relay contact is closed and a red LED is illuminated indicating a valid code is being received. This signal is then passed on to the gate controller, which automatically opens the gate or performs some other security function. This product is available with an AVI receiver and with an optional vehicle detector – both devices use the same street loop.

3D Model

Learning: All Diablo Controls AVI receivers are shipped in the unprogrammed mode. Before the receiver can be used for AVI, it must first learn the acceptable codes. To program a new code, the transmitter transmitting this code must first be energized and placed over the loop. Press and hold the “Learn” button until the red Valid LED starts blinking fast. Then simply release the button. This will store the new code in memory. Once this new code is received and learned, it will now activate each time this code is received. The receiver has the capability of storing up to two codes. If the unit is asked to learn a third code, the oldest code is discarded.

To erase all the stored codes, disconnect the MS connector from the unit. With the pushbutton firmly pressed, reconnect the MS connector. Continue to press the button in until the red Valid LED begins to blink slowly. Release the pushbutton. There are now no codes stored in memory and the unit is ready to learn new codes

LED Indicators: The green Power LED will be on solid to indicate the unit is operating and powered. The red Valid LED will turn on when the unit is receiving a valid code. If the red Valid LED is blinking slowly then this unit is un-programmed and has no codes stored to validate.

Outputs: Solid-state (open transistor collectors) for both detect and fail outputs. 30 mA maximum current sink- transient voltage protected.

Power: 12 to 30 volts DC

Operating Temperature: -35°F to 165°F (-37°C to 74°C)

Size: Height: 2.4″ (61 mm) Width: 0.8″ (20 mm) Depth: 2.25” (57 mm)

Connector: 10-position Molex Type 09-48-1104
Mates with many female PCB 0.156” pitch headers in use by some access control devices and gate operators.
