Diablo Controls AVI-100-RD (Single or Dual Code Receiver w/ Detector Vehicle)
The Diablo Controls AVI-100-RD is a receiver-and-detector style component for Diablo's Automatic Vehicle Identification system. It combines the AVI receiver function with an inductive loop vehicle detector, so a compatible vehicle-mounted AVI transmitter can be detected and verified as the vehicle approaches the controlled gate or barrier.
This type of system is different from a standard loop detector. A normal loop detector detects the presence of a vehicle only. An AVI receiver listens for a coded transmitter signal received through the pavement loop and then activates only when the programmed code is valid. That makes it useful for emergency access, mass transit, shuttle buses, trucking facilities, forklifts, airport access, rail equipment, and restricted commercial entrances.
Correct ordering depends on the existing AVI system design. The receiver code format, transmitter type, power version, loop layout, relay output, and whether the detector is built into the receiver all matter. The AVI-100-RD should not be substituted with a basic AVI-100-R receiver unless the system has a separate compatible detector.
Compatible With
Compatibility depends on the detector model, supply voltage, loop or probe type, wiring base, relay output needs, and how the gate, door, barrier, parking, or access-control panel is designed to receive a vehicle-detect signal.
- Diablo AVI automatic vehicle identification systems using compatible AVI transmitters
- AVI-X-1 single-code and AVI-X-2 dual-code transmitter applications when programmed for the site
- Emergency vehicle access, mass transit, shuttle, trucking, manufacturing, forklift, airport, rail, and restricted vehicle access uses
- Roadway loops installed for AVI signal pickup and vehicle detection
- Gate operators, barrier gates, and access-control panels accepting a valid-code relay output
- AVI-100-RD receiver-with-detector replacements where codes, voltage, and loop design match
- Not a direct replacement for AVI-100-R-LV or AVI-100-R-117 if the site depends on the integrated detector

Technician Note
AVI systems are usually programmed and documented for the site. Before replacement, record existing receiver settings, transmitter codes, power requirements, and loop wiring so the new unit can be matched correctly.
Before Ordering
- Confirm the site uses Diablo AVI transmitters, not standard radio remotes.
- Verify whether the existing receiver includes an integrated detector.
- Confirm power voltage and cabinet wiring.
- Confirm loop location and lead-in condition.
- Check code documentation and programming requirements before replacing the receiver.
Important Ordering Warning
An AVI receiver controls access based on coded vehicle identification. It should not be wired to bypass gate safety circuits or replace required vehicle/entrapment safety devices.
Professional Advisory
Vehicle detector wiring is part of the gate, door, parking, or access-control safety and command circuit. Do not bypass monitored safety devices or use a detector to defeat required entrapment protection. For high-voltage wiring, cabinet faults, nuisance detection, or unsafe gate movement, use a qualified gate or access-control technician.
Product Questions and Answers
How is AVI-100-RD different from a normal loop detector?
A normal loop detector senses any vehicle. The AVI-100-RD is part of a coded AVI system and responds to compatible programmed vehicle transmitters.
What does the RD version include?
The RD version is commonly described as a receiver with an integrated inductive loop vehicle detector.
Can this work with AVI-X transmitters?
Yes, it is part of the Diablo AVI system and is commonly associated with AVI-X single-code and dual-code transmitter applications when programmed for the site.
No. Those are receiver power/version references and may not include the integrated detector function of the RD model.
What should be verified before ordering?
Verify voltage, code programming, transmitter compatibility, loop layout, and whether the cabinet requires the receiver-with-detector version.
