Frequently Asked Questions : US Automatic Vehicle Detectors

Q1: What is the function of a US Automatic vehicle detector?

A1: A US Automatic vehicle detector is designed to sense the presence of a moving vehicle in a driveway. When a vehicle is detected, the sensor sends a signal to the gate control board to open the gate, allowing for hands-free egress.

Q2: How does a US Automatic exit sensor differ from an inductive loop?

A2: US Automatic typically utilizes probe-style exit sensors, which detect fluctuations in the earth's magnetic field caused by passing metallic vehicles. In contrast, inductive loops require a continuous wire loop buried in the pavement to sense electromagnetic changes.

Q3: Are US Automatic vehicle detectors compatible with other gate operator brands?

A3: While these detectors are optimized for US Automatic systems like the Patriot and Ranger, they often feature standard relay outputs. However, compatibility depends on the specific voltage and input requirements of the alternate control board, which should be verified in the operator's manual.

Q4: Can these detectors sense pedestrians or animals?

A4: No, US Automatic magnetic probe detectors are specifically calibrated to sense large moving masses of metal. They will not detect pedestrians, animals, or non-metallic objects, preventing unwanted gate openings.

Q5: What is the optimal distance from the gate to place a vehicle detector?

A5: The probe should typically be placed far enough inside the property to allow the gate to fully open before the vehicle reaches it. The exact distance varies based on the gate's opening speed and the property layout, as detailed in the manufacturer's technical manual.

Q6: Do weather conditions affect the performance of magnetic probe detectors?

A6: Because the probe is buried underground, it is generally unaffected by above-ground weather conditions like rain, snow, or fog. However, extreme ground freezing or pooling water that compromises the wire insulation can cause erratic behavior.

Q7: Can I adjust the sensitivity of a US Automatic exit sensor?

A7: Yes, many models include a sensitivity adjustment board or dial that connects to the control panel. This allows the system to be fine-tuned to detect smaller vehicles, such as motorcycles, or to ignore interference from nearby moving metal.

Q8: What type of wire is used to connect the sensor probe to the control board?

A8: The probes come pre-wired with a specific length of burial-rated, shielded cable. This cable is routed underground from the sensor location directly to the gate operator's control board to transmit the detection signal.

Q9: Does a US Automatic vehicle detector act as a safety device?

A9: No, standard exit probes are designed solely to trigger the gate to open and are not UL 325 compliant entrapment protection devices. A separate, monitored safety system, such as photo eyes or safety edges, is required to prevent the gate from closing on an obstruction.

Q10: What should be done if the vehicle detector continuously holds the gate open?

A10: A continuous open signal may indicate a short in the burial wire, incorrect sensitivity settings, or interference from a nearby metallic object. For advanced electrical diagnostics or component replacement, refer to the manufacturer's manual or hire a qualified local professional.
