PRICE $99.00

The EDI LMA-1150-HV is a DEFLECTOMETER single-channel inductive loop detector for professional gate, parking, and access-control vehicle detection systems. It is used with a buried inductive loop to send a relay signal to the operator or controller when a vehicle is present. This model uses 120 VAC to 240 VAC high-voltage detector power and provides single programmable relay output, making it important to match the original detector, socket wiring, input voltage, and fail mode before ordering. It may be used for compatible exit, safety, reverse, hold-open, arming, and presence loop applications where the controller accepts the detector's dry-contact output. Common service checks include loop condition, lead-in wiring, power at the detector socket, sensitivity setting, and nearby-loop crosstalk. For best results, replace by exact part number and confirm the gate operator or access-control wiring diagram.

Product Overview

The EDI LMA-1150-HV is a DEFLECTOMETER single-channel inductive loop detector used in professional gate, parking, and access-control installations. It connects to a saw-cut or preformed inductive loop in the pavement and monitors changes in loop inductance caused by a vehicle in the detection area. When a vehicle is detected, the detector changes its relay output so the gate operator, barrier gate controller, telephone entry system, or access-control panel can respond according to the way that loop input is programmed. This type of detector is commonly used for free-exit loops, safety/reverse loops, presence loops, hold-open loops, arming loops, and parking control lanes.

This LMA-1150 model is the LMA-1150-HV version, with single programmable relay output and 120 VAC to 240 VAC high-voltage detector power. The correct detector is not chosen by brand alone. The installer should match the original detector part number, input voltage, 11-pin socket wiring, relay output requirements, and desired fail-safe or fail-secure behavior. A low-voltage detector should not be placed into a high-voltage socket, and a fail-secure detector should not be substituted for a fail-safe detector unless the system design specifically calls for that behavior.

EDI detectors are commonly selected because they provide practical setup and troubleshooting features for field technicians. Depending on the series, features may include adjustable sensitivity, selectable loop frequency, sensitivity boost, loop fault monitoring, stored fault memory, output delay or extension, and LED indication for power, detect, and fault conditions. Those features help identify common loop problems such as open loops, shorted loops, large inductance changes, crosstalk between nearby loops, incorrect sensitivity settings, or a detector that is being powered from the wrong source.

Technician Note

Best suited when the detector socket is powered from a high-voltage source rather than a 12/24V control circuit. Match the original detector label and socket voltage before installation. Do not substitute for the low-voltage LMA-1150-LV or the fail-secure LMA-1150S versions.

Before Ordering

Confirm the exact model number printed on the original detector.
Confirm low-voltage or high-voltage detector input power at the socket.
Confirm fail-safe or fail-secure operation required by the gate or parking system.
Confirm whether the installation needs one relay output or dual relay outputs.
Inspect the loop wiring for open circuits, shorts, water intrusion, damaged lead-in wire, or incorrect loop inductance.
Confirm the 11-pin socket wiring and operator manual before applying power.

Professional Advisory

Loop detector wiring can affect gate safety, vehicle detection, and automatic gate behavior. Do not bypass monitored safety devices or use a detector to defeat required entrapment protection. If the gate moves unexpectedly, the loop circuit is damaged, or the detector socket voltage is not confirmed, have the system checked by a qualified gate or access-control technician.
