Grade 1 Weatherized Electromagnetic Lock | 1,200+ lb Holding Force | 12/24VDC | Stainless Steel | Fail-Safe

The Detex ML-1549W Weatherized Electromagnetic Lock is a heavy-duty commercial maglock designed for exterior doors, gates, and other openings exposed to demanding environmental conditions.

Providing approximately 1,200+ lbs. of holding force, the ML-1549W combines powerful access-control security with a rugged stainless-steel case and epoxy-filled construction for increased protection against weather and moisture.

The lock operates fail-safe, immediately releasing when electrical power is removed by an access-control system, fire/life-safety system, emergency release, or power failure.

Key Features

• 1,200+ lb holding force

• ANSI/BHMA Grade 1

• Weatherized electromagnetic lock

• Heavy-duty stainless-steel case

• Epoxy-filled for weather resistance

• 12/24VDC field-selectable voltage

• Fail-safe operation

• Releases immediately when power is removed

• Built-in bond sensor

• Non-handed design

• Floating armature helps compensate for door or gate misalignment

• All-steel magnetic core construction

• Threaded conduit fitting

• No moving mechanical parts to bind or wear

• Designed for exterior and demanding commercial applications

Weatherized Construction

The ML-1549W is specifically designed for installations where a conventional indoor electromagnetic lock may be exposed to moisture, weather, or harsh environmental conditions.

Weather-resistant features include:

• Stainless-steel housing

• Epoxy-filled magnetic assembly

• Threaded conduit connection

• Corrosion-resistant construction

• Rugged design for outdoor applications

This makes the ML-1549W an excellent choice for secured exterior doors and gates.

1,200+ lb Holding Force

The Detex ML-1549W provides approximately 1,200 pounds of electromagnetic holding force at the separation point.

When energized, the electromagnet securely bonds to the armature plate to help resist unauthorized entry.

The floating armature design allows the armature plate to properly align with the electromagnet, helping compensate for minor door or gate alignment variations.

Fail-Safe Operation

The ML-1549W operates as a fail-safe electromagnetic lock.

Power Applied

The electromagnet energizes and secures the opening.

Power Removed

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

This allows the lock to interface with properly designed:

• Fire alarm systems

• Emergency release devices

• Access-control systems

• Request-to-exit controls

• Remote release switches

• Building life-safety systems

Built-In Bond Sensor

The ML-1549W includes a built-in bond sensor for monitoring the status of the magnetic bond between the lock and armature.

This can provide useful status information to compatible access-control or security systems.

Dual-Voltage Operation

The ML-1549W supports both:

• 12VDC

• 24VDC

Voltage is field selectable, allowing the lock to integrate with a wide range of commercial access-control power supplies.

Electrical Specifications

12VDC: Approximately 0.45A
24VDC: Approximately 0.225A

Always use a properly rated and fused DC power supply.

ML-1549W vs. ML-1549WF

The ML-1549W is the standard weatherized configuration.

Detex also offers the ML-1549WF, a weatherized face-mount version for applications requiring an alternate mounting arrangement.

Verify the door, frame, or gate configuration before selecting the proper model.

Important Life-Safety Note

Electromagnetic locks must be installed as part of a properly designed and code-compliant access-control and egress system.

Installation requirements can vary depending on:

• Door type

• Occupancy

• Egress requirements

• Fire alarm integration

• Local building and fire codes

• Authority Having Jurisdiction requirements

Always verify applicable requirements before installation.
