The Alarm Controls 600LB is a single-door electromagnetic lock designed for commercial access control applications, providing 600 lbs of holding force with field-selectable 12/24 VDC operation. Equipped with an LED status indicator, magnetic bond sensor, and door status sensor, the 600LB monitors locking conditions on high-traffic interior doors. Its bracket-mounted design, built-in arc suppression, and instant-release operation support integration with electronic access control systems.

Alarm Controls 600LB 600 lb Single-Door Magnetic Lock with LED and Status Sensors

The Alarm Controls 600LB single magnetic lock provides 600 lbs of electromagnetic holding force for securing interior doors in commercial offices, institutional buildings, and controlled-access facilities. Designed for single-door applications, the lock uses an energized electromagnet and armature plate to maintain door security while allowing immediate release when power is interrupted. The integrated LED status indicator, magnetic bond sensor, and door status sensor provide feedback about door position and locking conditions, supporting access control systems that require monitoring of secured openings.

The 600LB operates on field-selectable 12 or 24 VDC power, drawing 505 mA at 12 VDC or 260 mA at 24 VDC. Its magnetic bond sensor provides SPDT relay contacts rated at 3A for communicating lock status to compatible control equipment. The magnet measures 9-7/8 inches long, 1-11/16 inches high, and 1 inch wide, while the armature measures 7-1/4 inches long, 1-1/2 inches high, and 1/2 inch wide. Additional construction features include built-in arc suppression, corrosion-resistant plated steel components, and a clear anodized aluminum (US28) finish. The lock operates within temperatures of 14 F to 131 F (-10 C to 55 C).

Designed for high-traffic interior access control applications, the 600LB electromagnetic door lock integrates with compatible access control panels, request-to-exit devices, electronic keypads, and regulated DC power supplies. The supplied E-Z mount header bracket, installation template, and self-drilling TEC screws simplify installation without specialized tools. Standard mounting accommodates appropriate outswinging door configurations, while inswinging installations require compatible L/Z mounting brackets. The lock's instant-release design eliminates residual magnetic holding delays, and its integrated door monitoring features help security systems distinguish between door position and magnetic bond status.

The Alarm Controls 600LB is identified in manufacturer documentation as a UL 294 recognized component, with additional UL 10C fire-rated, CAN/ULC-S104 fire-door-conformant, UL 864 listed, and CAN/ULC-S527 listed classifications. Installers must verify applicable assembly approvals, fire-door requirements, and local egress regulations before installation. The standard US28 clear anodized finish can be supplemented with an optional US40 Duranodic finish or decorative polished chrome and brass covers. Backed by a limited lifetime manufacturer warranty, the 600LB combines electromagnetic locking, door monitoring, and bracket-mounted installation for commercial single-door security applications.
