Weatherized for Harsh Environments

Unlike standard indoor magnetic locks, the ML-1549W is specifically weatherized for exterior applications.

Its stainless-steel housing and epoxy-filled construction help protect the electromagnetic components against moisture and environmental exposure.

This makes the ML-1549W ideal for installations such as:

• Exterior commercial doors

• Security gates

• Perimeter entrances

• Parking facilities

• Industrial access points

• Outdoor employee entrances

• Warehouse and loading areas

1,200+ lb Holding Force

The ML-1549W provides approximately 1,200 lbs. or more of holding force, helping resist forced entry at demanding commercial openings.

When energized, the electromagnet securely holds the armature plate against the lock until power is removed.

Fail-Safe Operation

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

Power Applied: Door or gate remains locked.

Power Removed: Magnetic lock immediately releases.

This allows the ML-1549W to integrate with compatible:

• Access-control systems

• Fire/life-safety systems

• Request-to-exit devices

• Key switches

• Push-to-exit controls

• Motion sensors

• Remote release switches

Built-In Bond Sensor

A built-in bond sensor allows compatible access-control or monitoring equipment to determine whether the magnetic lock has achieved proper contact with the armature plate.

This provides valuable status information for security and access-control systems.

Floating Armature Design

The floating armature helps compensate for minor door or gate misalignment, allowing the armature plate to properly align with the electromagnetic lock face.

Correct armature contact is essential for achieving the lock's rated holding force.

Dual-Voltage Operation

The ML-1549W can be configured for:

• 12VDC

• 24VDC

This dual-voltage capability provides flexibility when integrating the lock into new or existing access-control systems.
