280kg / 600lbs Single Door Electromagnetic Lock (Fail-Safe)

Product Overview

The LM-2802 Single Door Electromagnetic Lock is a heavy-duty, surface-mounted access control locking device engineered for standard single-leaf architectural doors. Operating on a fail-safe principle (unlocked when power is removed), this magnetic lock ensures uncompromised life-safety compliance, immediately releasing doors during emergency power interruptions or fire alarm events.

Constructed from premium anodized aluminum with high-grade magnetic steel laminations, the LM-2802 delivers a reliable holding force of 280 kg (600 lbs) without mechanical wear, latch jamming, or residual magnetism. Designed for versatile indoor deployment, it features dual-voltage operation (12V DC / 24V DC) with integrated surge and reverse-current protection to safeguard interconnected access controllers and power supplies. It is ideal for securing perimeter entries, interior access corridors, server rooms, and commercial facilities across wooden, glass, metal, and fireproof doors.

Key Features

• 280 kg (600 lbs) Holding Force: Provides robust, continuous magnetic clamping to prevent forced physical entry on single-leaf doors.

• Fail-Safe Operation: Automatically unlatches upon power loss, satisfying emergency egress and life-safety building code mandates.

• Dual Voltage Flexibility: Selectable 12V DC or 24V DC operation via onboard jumper configuration for easy integration into existing power infrastructures.

• Zero Residual Magnetism: Equipped with an anti-residual magnetism kick-off release pin to ensure instantaneous door release when de-energized.

• Built-in Surge Protection: Integrated MOV (Metal Oxide Varistor) protects the unit and access control panels against reverse EMF and electrical spikes.

• Durable Anodized Housing: Sandblasted aircraft-grade aluminum alloy body provides wear resistance and corrosion protection.

• Wide Bracket Interoperability: Compatible with standard L, Z, and U brackets for mounting on outswing, inswing, or frameless glass doors.
