Learning: 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 theMS connector from the unit. With the pushbutton firmly presed, reconnect the MS connector. Continue to press the button 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 to validate.
Sensitivity: Almost all traffic applications can be handled with sensitivity set at NORMAL (level 4). The sensitivity DIP Switches (S1, S2, and S3) should rarely be moved from NORMAL. However, the AVI-100-RD has eight settings varying fro LOW of level 0 to a HIGH of level 7.
Sensitivity | S1 | S2 | S3 | ?L% | Response Time (ms) |
0 | Off | Off | Off | 1.28 | .25 |
1 | On | Off | Off | .64 | 0.5 |
2 | Off | On | Off | .32 | 1 |
3 | On | On | Off | .16 | 2 |

Frequency: Automatically tunes within one of four frequencies.
Pulse/Presence: With this switch turned on, the main output will be a 125 ms pulse each time a vehicle enters the loop detection area. If the vehicle remains within the loop for two seconds, the detector will automatically retune, making it ready for the next vehicle to arrive. If this switch is turned off the detector will output presence.
Fail Safe vs Fail Secure: A fail safe detector will output "detect" when the loop is failed. This is always useful on a safety loop. On the free exit loop this will keep the gate open until the situation is fixed. This is useful in applications where it is important to allow traffic flow to continue. A fail secure detector will never output "detect" when the loop circuit is failed. This will keep the gate closed. This is useful in high-security areas or installations where containment is needed. The AVI-100-RD is factory configured for fail safe operation. To change the operation to fail secure, open the detector and remove Jumper J1 on the main PC board. Note: Never use a fail secure detector on a safety loop.
