Alarm Controls AM6375 US28 — 5-Piece Z Bracket for 1200D Electromagnetic Lock (In-Swing Doors, Clear Anodized)

The Alarm Controls AM6375 is a 5-piece Z bracket mounting kit designed specifically for the Alarm Controls 1200D double-door electromagnetic lock on in-swinging door applications. The Z bracket configuration positions the maglock armature plate correctly relative to the door face, ensuring proper magnetic bond alignment when the door is in the closed position. The kit ships in a Clear Anodized (US28) finish as standard, providing a clean, professional appearance compatible with aluminum door frames and modern commercial storefronts.

What Is a Z Bracket and Why Is It Required for In-Swing Doors?

Electromagnetic locks mount to the frame header and attract a steel armature plate mounted to the door face. On an in-swinging door, the door moves toward the secured side — away from the standard flush frame mount position. A Z bracket offsets the armature plate outward, maintaining correct face-to-face contact between the magnet body and armature when the door is fully closed. Without the correct bracket geometry, the maglock will not achieve its rated holding force and bond sensor operation will be unreliable. The AM6375 provides the proper standoff and alignment geometry for the 1200D series (1,200 lb holding force, double-door configuration).

Key Features and Benefits

• 5-piece kit — complete mounting assembly for in-swing door installation on 1200D maglocks
• Clear Anodized (US28) finish — corrosion-resistant anodized aluminum, low-profile appearance
• Designed for the Alarm Controls 1200D — double-door, 1,200 lb holding force electromagnetic lock with LED, bond sensor, and door status sensor
• In-swing door geometry — proper offset allows full magnetic contact on doors that swing toward the secured side
• Surface-mounted installation — no mortising required; integrates with standard hollow metal and aluminum frame headers

Compatible Lock and Application Context

The 1200D maglock is a fail-safe electromagnetic lock — power loss releases the door, making it appropriate for access-controlled egress openings where building codes require immediate release on fire alarm or power failure. As with all electromagnetic locks, the 1200D does not provide door latching; fire-labeled openings require separate positive-latching hardware installed alongside the maglock. A compliant Request to Exit (RTE) device — such as a push-button station or motion-sensor RTE — must be specified to allow egress from the secured side without a credential, as required by model codes (IBC and local equivalents).

Typical Applications

• Commercial office building interior corridors and suite entry doors (in-swing)
• Healthcare and institutional secured access points
• School and university access-controlled entry doors
• Government and secure facility in-swing door openings with 1200 lb-class maglocks
