Alarm Lock DL3500CR26D Classroom Digital Mortise Lock

Product Description

The ALARM LOCK DL3500CR26D is a reversible classroom digital mortise lock designed for access control applications in educational and commercial facilities. It features a straight lever handle in a satin chrome finish and operates as a standalone keyless entry unit, eliminating the need for traditional keys. The mortise-style body integrates directly into the door prep, providing a robust mechanical and electronic locking solution suited for high-traffic classroom and office environments. Licensed locksmiths, access control technicians, and security integrators are the primary installers of this hardware.

This lock is built for classroom-function applications where the lever remains locked from the outside at all times and is operated by entering a valid code. It suits interior doors in K-12 schools, universities, government buildings, and commercial offices where access needs to be controlled door by door without a central wired infrastructure. The reversible design allows installation on doors with either a left-hand or right-hand swing, making it flexible for varied facility layouts.

Key Features

• Classroom function mortise lock: outside lever locked by default, code entry required for access

• Straight lever handle in satin chrome (26D) finish for a clean, professional appearance

Compatibility

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with mortise lock prep standards. Power down or disconnect any existing electronic hardware before beginning the replacement or new installation. Follow applicable building and fire codes, including IBC egress requirements, when configuring classroom-function locks in occupied facilities. Do not force the lock body into an undersized mortise pocket, as this can damage internal components.
