Alarm Controls 600D Magnetic Lock, 600lb, Double Door, Clear Anodized Aluminum

The Alarm Controls 600D is a double-door electromagnetic lock providing 600 lbs of holding force per door for commercial access control applications. Operating on field-selectable 12/24 VDC power, the lock features a clear anodized aluminum housing, built-in arc suppression, and instant-release operation. Its E-Z mount header bracket, installation template, and self-drilling TEC screws simplify installation on compatible double-door openings while supporting integration with electronic access control systems.

Alarm Controls 600D 600 lb Double-Door Magnetic Lock, 12/24 VDC, Clear Anodized

The Alarm Controls 600D double magnetic lock provides electromagnetic locking for pairs of interior doors in commercial offices, educational facilities, institutional buildings, and controlled-access entrances. Featuring two electromagnetic locking sections rated at 600 lbs of holding force per door, the 600D secures both door leaves through a single header-mounted assembly. The lock uses an energized electromagnet and corresponding armature plates to maintain door security, releasing when electrical power is interrupted. Its fail-safe, non-holdover design supports applications requiring immediate door release through compatible access control and emergency egress systems. The standard 600D configuration provides electromagnetic locking without the integrated LED, magnetic bond sensor, or door status sensor supplied with the separately available 600DLB model.

The 600D operates on field-selectable 12 or 24 VDC power, with manufacturer-published current consumption of 505 mA per magnet at 12 VDC or 260 mA per magnet at 24 VDC. Both locking sections together require approximately 1.01A at 12 VDC or 520 mA at 24 VDC. The complete magnetic lock assembly measures 19-3/4 inches long, 1-7/8 inches high, and 1 inch wide, while each armature plate measures 7-1/4 inches long, 1-1/2 inches high, and 5/8 inch wide. Additional construction features include a clear anodized aluminum (US28) finish, corrosion-resistant plated steel components, and built-in arc suppression to reduce electrical transients during switching. The lock operates within a temperature range of 14 F to 131 F (-10 C to 55 C).

The Alarm Controls 600D electromagnetic double-door lock uses the manufacturer's E-Z mounting system, including a header bracket, installation template, and self-drilling TEC screws for attachment to compatible door frames. For typical outswinging applications, the electromagnetic assembly mounts to the stationary door header while the armature plates attach to the individual door leaves. The supplied armature mounting hardware allows limited movement for proper magnetic surface alignment. Inswinging doors require compatible L/Z mounting brackets, including the separately available Alarm Controls AM3375 bracket set for 600 lb double magnetic locks. Additional accessories include angle brackets, filler plates, and drop-down mounting plates for installations with restricted header clearance. The 600D integrates with compatible access control panels, regulated DC power supplies, request-to-exit devices, and emergency release controls.

The Alarm Controls 600D 600 lb double electromagnetic lock is identified in current manufacturer documentation as a UL 294 recognized component, with additional UL 10C fire-rated, CAN/ULC-S104 fire-door-conformant, ULC-S527 listed, and UL 864 listed classifications. Its instant-release operation eliminates residual magnetic holding delays when the lock is de-energized, while the absence of internal moving locking components reduces mechanical maintenance requirements. The standard US28 clear anodized finish is complemented by an optional US40 Duranodic configuration and decorative polished chrome or brass covers. Backed by a limited lifetime manufacturer warranty, the 600D provides double-door electromagnetic locking for commercial interior access control systems. Installers must verify compatible door construction, electrical capacity, mounting requirements, fire-door approvals, and applicable emergency egress regulations before installation.
