Grade 1 Commercial Maglock | 1,500+ lb Holding Force | 12/24VDC | Fail-Safe | Surface Mount

The Detex ML-1548 Electromagnetic Lock is a heavy-duty commercial maglock engineered to provide powerful and dependable access-control security for commercial, industrial, and institutional door openings.

Part of the Detex ML-1500 Series, the ML-1548 provides more than 1,500 lbs. of holding force, delivering exceptional resistance against forced entry while maintaining positive fail-safe operation for life-safety applications.

With no moving mechanical parts to bind or wear, the ML-1548 provides quiet, reliable, low-maintenance operation. When electrical power is removed by an access-control system, fire/life-safety system, or emergency release device, the magnetic lock releases immediately.

1,500+ lb Holding Force

The ML-1548 provides more than 1,500 pounds of electromagnetic holding force, making it suitable for demanding commercial openings where resistance to forced entry is required.

When energized, the electromagnet bonds securely to the armature plate mounted on the door, creating a powerful locking force without conventional moving locking components.

Fail-Safe Operation

The Detex ML-1548 operates as a fail-safe magnetic lock.

Power Applied

The electromagnet energizes and secures the door.

Power Removed

The magnetic field releases immediately, allowing the door to open.

This operating principle makes the ML-1548 suitable for properly designed access-control and life-safety systems where the lock must release upon:

• Fire alarm activation

• Emergency release

• Loss of electrical power

• Access-control authorization

• Request-to-exit activation

All installations must comply with applicable building, fire, electrical, accessibility, and life-safety codes.

Dual-Voltage Operation

The ML-1548 features 12/24VDC voltage-sensing input, providing flexibility when integrating the lock with commercial access-control power supplies and door-control systems.

This makes the lock suitable for a wide range of new installations and replacement projects.

Easy Surface-Mount Installation

Detex designed the ML-1500 Series for simplified installation.

Installation features include:

• Interlocking slide mounting plate

• Peel-and-stick installation template

• Convenient wiring terminals

• Wire access cover

• Non-handed configuration

• Adjustable mounting provisions

The lock can be installed on either left- or right-hand openings when configured with the appropriate mounting hardware.

Depending on the opening and jurisdiction, additional components may be required, including:

• Fire alarm release

• Request-to-exit sensor

• Emergency release button

• Door position monitoring

• Access-control equipment

• Approved power supply

Always verify requirements with the applicable authority having jurisdiction before installation.
