Product Overview
The LMA-1150S-HV is the high-voltage fail-secure member of the LMA-1150 detector family. It is used where the detector power circuit is 120 VAC or 240 VAC and the control system is wired around a single relay output. This is not a substitute for the LV version and should not be installed simply because the connector looks the same. In service work, this detector may be replaced when the vehicle loop no longer produces a reliable call, when the display reports stored faults, or when the relay output is no longer switching correctly. High-voltage detector replacement should be handled by a qualified technician because incorrect voltage selection can damage the detector or create an unsafe cabinet condition.
This product is best selected by matching the exact part number and the job-site wiring, not just by appearance. EDI detector families include low-voltage, high-voltage, low-power, solid-state-output, relay-output, fail-safe, and fail-secure versions. Those details affect how the detector powers up, how it reports a vehicle, and how it behaves when the loop is open, shorted, or out of range.
Compatible With
This item may be used with the following products, systems, or application groups when the original part number, voltage, connector style, and wiring match:
- EDI LMA-1150 and LMA-1250 style 11-pin box type detector applications
- Gate operator control cabinets that use a matching 11-pin Amphenol box type detector connector
- Exit loop, safety loop, shadow loop, and presence loop installations where relay output detector wiring is required
- Commercial parking, access-control, drive-through, and gate operator panels using compatible 11-pin detector wiring
- Replacement work where the original detector label, wiring harness, voltage class, and fail-safe or fail-secure behavior match

Technician Note
When replacing a loop detector, do not assume the detector is the only failed part. A damaged loop, wet lead-in splice, poor terminal connection, moving gate steel near the loop, or another nearby loop on a close frequency can create symptoms that look like a bad detector. The best practice is to confirm loop resistance, insulation condition, power voltage, and output wiring before replacing parts.
Before Ordering
- Match the exact part number or approved replacement reference from the original detector label.
- Confirm voltage class before applying power. Low-voltage and high-voltage versions are not interchangeable.
- Confirm connector style, harness type, and pinout before replacing a 10-pin or 11-pin detector.
- Confirm whether the application needs solid-state outputs or relay outputs.
- Confirm fail-safe or fail-secure behavior when the original detector uses an S version.
- Check loop wire, lead-in splices, and frequency separation if the original complaint is intermittent detection or false calls.
- Do not use a loop detector as a substitute for required monitored photo eyes, safety edges, or other entrapment protection devices.
Professional Advisory
Loop detector wiring is often located inside the same cabinet as operator power wiring. If the cabinet has high voltage, damaged wiring, water intrusion, missing safety devices, or unpredictable gate movement, the system should be inspected by a qualified gate technician before replacement parts are installed.
Important Ordering Warning
This is a high-voltage detector version. Do not replace a low-voltage detector with an HV model. Match the original voltage label and have high-voltage cabinet work handled by a qualified technician.
Important Ordering Warning
This row is written for the fail-secure S version. Fail-secure and standard fail-safe versions can behave differently during loop faults. Match the original detector behavior before ordering.
Product Q&A
What voltage is the LMA-1150S-HV for?
The HV version is commonly listed for 120 VAC and 240 VAC detector power applications.
Can I replace an LMA-1150S-LV with this HV model?
No. LV and HV versions are not interchangeable unless the power circuit is changed and verified by a qualified technician.
What does fail-secure mean for this detector?
Fail-secure refers to the detector output behavior during certain loop fault conditions. It should match the original system design.
Is this a dual relay detector?
No. The LMA-1150 family is a single programmable relay output detector family.
What is the safest way to confirm fitment?
Confirm the original part number, voltage printed on the detector, harness pinout, and operator wiring diagram before ordering.
