Alarm Controls AM3315 - Armature and Mounting Plates for 600 & 1200 Series

The AM3315 is an armature and mounting plate set for Alarm Controls magnetic locks in the 600 and 1200 Series. The armature is the steel plate that mounts on the door leaf and the magnet pulls against; the mounting plate is the bracket the maglock body fastens to. It is hardware, not a lock, so it only makes sense as a replacement or spare for a 600 or 1200 Series maglock installation.

Yes. The AM3315 covers both holding force classes, 600 and 1200, in the Alarm Controls line. One part number serves either lock, so you do not need to order differently based on holding force.

Often yes. A magnetic lock's holding force depends on clean, flat, full contact between the magnet face and the armature, so a scored, bent, or loosened armature is a common cause of a lock that will not hold. The AM3315 lets you replace the armature and its mounting plate on a 600 or 1200 Series lock without pulling and rewiring the magnet body. If the magnet itself is still energizing and the frame bracket is sound, plates are the cheaper fix.

Treat the AM3315 as an Alarm Controls 600 and 1200 Series part only. Armature geometry, thickness, and bolt pattern are specific to the magnet face they pair with, so swapping an armature between brands is not something you should assume works. Alarm Controls publishes a magnetic lock cross reference guide for identifying which of their locks corresponds to another manufacturer's model, and that is the right way to confirm what you actually have on the door before ordering plates.

No. This is the armature plate and mounting plate hardware only. The magnet body, power supply, release device, and any request-to-exit or door-status wiring are separate. If you are building a new opening rather than repairing one, order the 600 or 1200 Series lock and specify plates with it.

Clear anodized aluminum, US28. That is the standard maglock finish in the Alarm Controls line, so it matches the lock body and typical aluminum storefront framing rather than standing out against it. It is the only finish offered on this part.

It is a commercial-duty part, catalogued for commercial rather than residential service. That fits where these maglocks actually go: storefront and interior access-controlled openings in offices, schools, and multi-family common doors.
