Alarm Controls Corporation DL-24 Heavy Duty Door Loop

Product Description

The Alarm Controls Corporation DL-24 is a heavy duty door loop designed to carry low-voltage wiring across a door or gate hinge gap. It protects conductors from repeated flexing stress as a door opens and closes, maintaining a continuous electrical path for access control, alarm, or power transfer applications. The loop is rated for the 3/8 inch gap typical of standard commercial door frames and is built to withstand high-cycle, high-traffic environments. Installation is handled by licensed electricians or access control technicians working on commercial or industrial door hardware.

The DL-24 is suited for commercial and light industrial applications where low-voltage wiring must pass from a fixed door frame to a moving door or gate leaf. Typical uses include door position sensors, electric locks, request-to-exit devices, and intercom or power transfer scenarios. It fits installations where the hinge gap is 3/8 inch and the application demands a durable, long-service-cycle solution rather than a standard duty loop.

Key Features

• Heavy duty construction rated for high-cycle door and gate applications
• 3/8 inch gap clearance for standard commercial door hinge spacing
• Protects conductors from flex fatigue caused by repeated door movement
• Maintains continuous low-voltage circuit across a moving door leaf
• Sold as a single unit for straightforward replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-install door loop for commercial access control and door alarm systems requiring a 3/8 inch hinge gap conductor transfer solution.

Installation Notes

Installation is typically performed by a licensed electrician or certified access control technician. De-energize all circuits connected to the door loop before beginning work and verify the door gap measurement matches the 3/8 inch specification before installing. Secure the loop housing to both the frame and door leaf per the manufacturer manual to prevent strain on the conductors. Consult local electrical codes and NEC low-voltage wiring guidelines for conductor type and routing requirements.
