Frequently Asked Questions : Linear / Nortek Vehicle Detectors

Q1: What is a Linear or Nortek vehicle detector?

A1: A Linear or Nortek vehicle detector is an electronic component used in gate automation to sense the presence of a vehicle. It typically interfaces with an inductive loop to trigger a gate to open, hold, or reverse direction upon vehicle detection.

Q2: How does a Linear vehicle detector interact with an inductive loop?

A2: The detector module monitors a buried wire loop for changes in the electromagnetic field caused by the metal mass of a passing vehicle. When a change is detected, it sends a relay signal to the gate control board.

Q3: Are Nortek vehicle detectors compatible with all gate control boards?

A3: While these detectors feature standard relay outputs designed for broad compatibility, they require a logic board capable of processing external loop inputs. It is necessary to verify specific voltage and terminal requirements in the gate operator's manual.

Q4: What are the fail-safe and fail-secure modes on these detectors?

A4: In fail-safe mode, a power loss or detector fault will cause the gate to remain open to prevent vehicle entrapment. In fail-secure mode, the system ignores the loop failure, and the gate remains closed but operational via other access controls.

Q5: How do sensitivity settings function on a Linear vehicle detector?

A5: Sensitivity settings adjust the detection threshold based on the size and metallic mass of the target vehicles. Increasing sensitivity helps detect smaller vehicles like motorcycles, while decreasing it prevents false triggers from adjacent lanes.

Q6: Can a single detector module manage multiple loop wires?

A6: Standard plug-in loop detectors are generally designed to manage a single loop circuit to ensure accurate sensitivity. If multiple loops are required for safety and exit functions, separate detectors must be installed for each specific loop.

Q7: What is the purpose of the frequency setting on a Nortek loop detector?

A7: The frequency setting alters the operating frequency of the inductive loop. Setting adjacent loops to different frequencies is critical to prevent cross-talk and electrical interference between the separate systems.

Q8: What do the LED diagnostic lights indicate on a Linear detector?

A8: LED indicators provide operational status feedback, including power, vehicle detection, or loop failure. A flashing error light typically signifies a short circuit, an open loop, or an inductance issue within the buried wire.

Q9: Can environmental factors affect the performance of a buried vehicle detector?

A9: The detector module is safely housed within the operator cabinet, but extreme ground shifting or moisture intrusion can damage the buried loop wire. Degraded wire insulation often causes the detector to receive erratic inductance readings.

Q10: What should be done if the gate remains open due to a suspected detector fault?

A10: First, ensure no metallic objects are resting on the buried loop area and check the detector for active fault lights. For advanced electrical testing with a megohmmeter or component replacement, refer to the technical manual or hire a qualified local professional.
