Commercial Magnetic Door Locks | Fail-Safe Operation | Access Control Compatible | LED & Bond Monitoring Options | US28 Aluminum Finish

Secure commercial entrances, offices, warehouses, and controlled-access openings with the Alarm Controls 600 Series Electromagnetic Locks, featuring 600 pounds of rated holding force per magnet and dependable fail-safe operation.

Manufactured by Alarm Controls, an ASSA ABLOY company, the 600 Series is designed for commercial access-control applications requiring reliable magnetic locking, convenient installation, and multiple monitoring options.

Available in single-door, double-door, and weather-resistant gate configurations, the 600 Series allows customers to select the appropriate electromagnetic lock for their specific opening.

Choose from standard magnetic locking, LED indication, integrated bond and door-position monitoring, or a weather-resistant model for sliding and swinging gates.

The standard 600 Series magnetic locks feature field-selectable 12V DC or 24V DC operation, built-in arc suppression, instant-release technology, and Alarm Controls' E-Z mounting system.

When electrical power is applied, the electromagnet attracts the corresponding steel armature plate to secure the opening. When power is interrupted, magnetic holding force releases, allowing the lock to integrate into appropriately designed access-control and emergency-egress systems.

With clear anodized aluminum finishes, optional Duranodic configurations, and compatible mounting accessories, the Alarm Controls 600 Series provides flexible security solutions for commercial buildings and institutional facilities.

Access Control & Monitoring Features

1. Fail-Safe Electromagnetic Locking

The Alarm Controls 600 Series uses electromagnetic locking technology.

When electrical power is applied, the magnet creates a magnetic bond with the matching steel armature plate.

When power is interrupted, the magnetic holding force releases.

This fail-safe design allows integration with properly configured access-control and emergency-release systems.

2. Magnetic Bond Monitoring

The 600LB and 600DLB include bond sensors that provide information about the connection between the energized magnet and corresponding armature plate.

The sensors feature SPDT relay contacts rated at 3A, allowing compatible security systems to monitor magnetic bond status.

3. Door Position Monitoring

The monitored models also include door-position sensors.

When connected to compatible monitoring equipment, these sensors can help distinguish between a door that is physically closed and one that is magnetically secured.

4. LED Status Indication

LED indicators are included on:

• 600L

• 600LB

• 600DLB

The 600S and 600D are standard locking models without integrated status LEDs.

The 600WP is not advertised as including an LED indicator.

5. Instant-Release Technology

Standard 600 Series door models feature instant-release technology designed to reduce residual magnetic holding after electrical power is removed.

This helps permit prompt opening following an authorized release command.

6. Built-In Arc Suppression

Standard single- and double-door models feature built-in arc suppression to help control electrical transients associated with switching electromagnetic loads.

Installation & Compatibility

Alarm Controls 600 Series electromagnetic locks should be installed by qualified commercial door hardware and access-control professionals.

The magnet is mounted to the appropriate fixed frame, header, or gate structure, while the corresponding steel armature plate is mounted to the moving door or gate.

Correct alignment and full magnetic contact are essential to obtaining rated holding force.

Electrical Requirements

Single-Door Models 600S, 600L & 600LB

• 12V DC: 505mA

• 24V DC: 260mA

Double-Door Models 600D & 600DLB

• 12V DC: 1,010mA total

• 24V DC: 520mA total

Weather-Resistant Model 600WP

• 12V DC: 500mA

• 24V DC: 250mA

These electrical values follow Alarm Controls' model-specific data sheets. Supply sizing should include appropriate capacity for additional access-control devices and the actual equipment revision.

Mounting Considerations

For standard commercial door applications:

• Verify the door swing and frame configuration.

• Confirm sufficient header mounting space.

• Use the manufacturer's installation template.

• Mount the electromagnet and armature so their contact surfaces align.

• Select compatible L-brackets or Z-brackets where necessary.

• Use the appropriate regulated DC power supply.

• Configure the correct operating voltage before applying power.

• Integrate required access-control and emergency-release controls.

• Test magnetic holding, lock release, and monitoring functions.

Important Installation Information

• Select the correct model based on single-door, double-door, or weather-resistant gate use.

• Double-door models provide 600 lbs of holding force per magnet, not 600 lbs shared between both doors.

• LED indication, bond monitoring, and door-position monitoring are model-specific features.

• Standard 600S, 600L, 600LB, 600D, and 600DLB models are recommended primarily for interior commercial doors.

• The 600WP is specifically designed for weather-resistant gate applications.

• All models require an appropriate regulated DC power supply.

• Fail-safe maglocks release magnetic holding force when power is interrupted.

• A lock's fail-safe operation alone does not establish that an installed doorway meets applicable egress codes.

• Request-to-exit, emergency-release, fire alarm, and access-control connections must comply with the approved life-safety design.

• Door and gate construction must be suitable for the selected lock and mounting hardware.

• Specialty brackets may be required for inswinging or nonstandard configurations.

• Electric locks do not independently operate a mechanical latch or door closer.

• Power supplies, controllers, card readers, release switches, specialty brackets, and other equipment are sold separately unless explicitly included.

• Installations must follow Alarm Controls' instructions and the requirements of the local Authority Having Jurisdiction.
