Liftmaster 50-DSP7LP Loop Detector Low Power Fail-safe

Product Description

The LIFTMASTER 50-DSP7LP is a low-power, fail-safe inductive loop detector designed for gate access control applications. Loop detectors sense vehicle presence through embedded wire loops in the pavement, triggering gate operators to open or hold open when a vehicle is detected. The fail-safe design ensures the gate defaults to a safe state in the event of a power interruption or loop fault, a critical requirement in high-traffic commercial and industrial access points. Licensed gate system technicians and access control installers are the primary trades working with this component.

This loop detector is suited for use in commercial and industrial gate controller installations where reliable vehicle detection and low power consumption are required. Typical applications include parking facilities, loading dock access points, security perimeters, and automated entry lanes. The fail-safe operation mode is especially relevant in sites where uncontrolled gate closure could pose a safety or liability risk. It is sold as an individual unit and is intended for integration into a gate operator control system.

Key Features

• Fail-safe output holds gate in safe state on loop fault or power loss
• Low-power design suited for energy-conscious installations
• Inductive loop detection technology for reliable vehicle sensing
• Intended for integration with gate operator control boards
• Sold as a single unit for direct replacement or new installation

Compatibility

Designed as an OEM-style replacement or upgrade component for commercial and industrial inductive loop-based gate controller systems.

Installation Notes

Installation should be performed by a qualified gate system technician or licensed access control professional. Disconnect and lock out power to the gate operator before wiring the detector into the control board. The inductive loop wire must be properly embedded and sealed in the pavement prior to connecting to this detector. Follow local codes and the gate operator manufacturer wiring diagrams for proper terminal connections.
