Commercial Electromagnetic Door Locks | Fail-Safe Operation | Access Control Compatible | Optional LED & Bond Monitoring | Clear Anodized Aluminum

Secure commercial entrances, industrial facilities, and controlled-access openings with the Alarm Controls 1200 Series Heavy-Duty Electromagnetic Locks, designed to deliver 1,200 pounds of rated magnetic holding force per locking assembly.

Manufactured by Alarm Controls, an ASSA ABLOY company, the 1200 Series provides reliable electromagnetic locking solutions for commercial offices, schools, healthcare facilities, warehouses, government buildings, and institutional properties.

Available in single-door, double-door, and weatherproof gate configurations, the series offers flexible solutions for a wide range of commercial access-control applications.

Choose from basic electromagnetic locking, LED status indication, integrated magnetic bond and door-position monitoring, or a heavy-duty weather-resistant gate lock.

The standard 1200 Series models support field-selectable 12V DC or 24V DC operation and feature fail-safe magnetic locking technology.

When electrical power is applied, the electromagnet creates a magnetic bond with the matching armature plate, securing the entrance. When power is removed, the magnetic holding force releases.

Select models also feature Alarm Controls' E-Z Mount System, built-in arc suppression, instant-release technology, and corrosion-resistant construction for professional commercial installations.

With their heavy-duty holding force, multiple monitoring options, and compatibility with properly designed access-control systems, Alarm Controls 1200 Series maglocks provide dependable electronic door security.

Access Control & Monitoring Features

Fail-Safe Magnetic Locking

The Alarm Controls 1200 Series uses electromagnetic locking technology.

When power is applied, the magnetic field attracts the corresponding armature plate, holding the door or gate closed.

When power is removed, the magnetic holding force releases.

This operating principle allows the locks to integrate with properly designed access-control and emergency-release equipment.

Magnetic Bond Monitoring

The 1200LB and 1200D provide magnetic bond sensing.

Bond monitoring helps connected security systems determine whether the armature plate has established the required magnetic bond with the energized magnet.

This provides more detailed security information than a basic lock-power indication.

Door Position Monitoring

The 1200LB and 1200D also include door status sensors.

These sensors allow appropriately connected monitoring equipment to detect door-position changes, helping distinguish between a door that is physically closed and a door that is magnetically secured.

LED Status Indication

LED indication is available on selected models:

• 1200L: Red indicating LED.

• 1200LB: Status LED with bond-monitoring functions.

• 1200D: Bi-color LED indicators.

The standard 1200S and 1200WP do not list integrated LED status indication.

Compatible Access Control Equipment

Alarm Controls 1200 Series magnetic locks can be incorporated into appropriately designed commercial access-control systems using compatible:

• Access-control panels and controllers

• Proximity card readers

• Keypad entry systems

• Request-to-exit sensors

• Push-to-exit buttons

• Emergency release switches

• Key-operated switches

• Door status monitoring systems

• Fire alarm release interfaces

• Regulated 12V DC and 24V DC power supplies

• Security annunciation equipment

Equipment compatibility, required release methods, and code requirements depend on the opening and installation.

Installation & Compatibility

Alarm Controls 1200 Series magnetic locks should be installed by qualified access-control or commercial door hardware professionals.

The electromagnetic lock assembly is mounted to the appropriate frame, header, or gate structure, while the armature plate is attached to the matching moving door or gate leaf.

Correct alignment is critical to achieving the specified holding force.

Electrical Requirements

Each standard single-door magnet requires approximately:

• 12V DC: 505mA

• 24V DC: 260mA

The 1200D contains two magnets and requires approximately:

• 12V DC: 1.01A total

• 24V DC: 0.52A total

The selected power supply must be properly rated for the total system load, including any additional controllers or connected devices.

Important Installation Information

• Select the correct model for single-door, double-door, or weather-resistant gate applications.

• The 1,200 lb rating applies to each individual magnet.

• For the 1200D, the rating is 1,200 lbs per door leaf, not 1,200 lbs divided between two doors.

• LED, bond-monitoring, and door-status features vary by model.

• All locks require an appropriate regulated DC power source.

• Fail-safe maglocks release magnetic holding force upon loss of power.

• Required request-to-exit devices, emergency-release controls, and fire alarm interfaces depend on the installation and applicable codes.

• Do not assume that a standard 1200S, 1200L, 1200LB, or 1200D has the same weather-resistant construction as the 1200WP.

• Inswinging doors and nonstandard frames may require special mounting brackets.

• Electric locking systems must be installed according to manufacturer instructions and applicable life-safety requirements.

• Power supplies, access-control devices, mounting brackets, and specialty accessories are sold separately unless expressly included.
