Secure demanding commercial openings with the Detex ML-1548 Electromagnetic Lock, a heavy-duty Grade 1 maglock providing more than 1,500 lbs. of holding force.

Designed for commercial, institutional, and industrial access-control applications, the ML-1548 combines powerful electromagnetic locking with instantaneous fail-safe release. When power is removed by an access-control system, fire/life-safety system, or remote control, the magnetic lock immediately releases.

With no moving locking components to bind or wear, the ML-1548 provides dependable, low-maintenance security for high-use commercial doors.

1,500+ lb Holding Force

The ML-1548 provides more than 1,500 lbs. of electromagnetic holding force, making it well suited for openings requiring substantial resistance against forced entry.

Once energized, the armature plate is held firmly against the magnetic lock until electrical power is removed.

Fail-Safe Operation

The ML-1548 operates as a fail-safe locking device.

Power applied: Door remains magnetically locked.

Power removed: Lock immediately releases.

This operating principle allows the ML-1548 to integrate with compatible:

• Access-control systems

• Fire/life-safety systems

• Key switches

• Push-to-exit controls

• Motion sensors

• Remote release switches

• Door-control systems

Always configure electromagnetic locking systems according to applicable building, fire, accessibility, and life-safety codes.

Dual-Voltage Operation

The ML-1548 accepts:

• 12VDC

• 24VDC

The voltage-sensing input simplifies installation when integrating the lock into compatible commercial access-control power systems.

Easy Installation

Detex incorporates several installation-friendly features into the ML-1548.

The interlocking slide mounting plate allows the mounting hardware to be installed independently of the magnetic lock, while the peel-and-stick template helps technicians accurately position the lock and armature.

Numbered terminal-block connections further simplify electrical installation and servicing.
