Liftmaster LPEXP Loop Detector Gate Controller

Product Description

The LIFTMASTER LPEXP is a loop detector designed for use in gate control systems. It senses the presence of vehicles by detecting changes in the inductance of a wire loop embedded in the pavement. When a vehicle passes over or rests on the loop, the detector triggers the gate controller to open, hold, or close as programmed. Gate installation technicians and access control professionals install and commission this device as part of automated entry and exit systems.

The LPEXP is suited for residential and commercial gate controller applications where reliable vehicle detection is required at entry and exit points. It integrates with gate operator systems that accept a standard loop detector input. Typical installations include driveway gates, parking facility entries, and commercial access control lanes where pavement-embedded loops are used.

Key Features

• Detects vehicle presence via inductance changes in a pavement-embedded wire loop
• Designed for integration with compatible gate controller systems
• Sold as a single unit for straightforward replacement or new installation
• Compact form factor suited for mounting within a gate operator enclosure

Compatibility

Designed as an OEM-style replacement or upgrade component for gate controller systems that support a standard loop detector module input.

Installation Notes

Installation should be performed by a qualified gate system technician or access control professional. Disconnect power to the gate operator before removing or installing the loop detector module. The pavement loop lead-in wire must be properly twisted and routed to minimize interference before connecting to the detector terminals. Follow all applicable local codes and the gate operator manufacturer guidelines during installation.
