Alarm Controls AM3331 – Frequently Asked Questions
1) What is an Alarm Controls drop down plate for double magnetic locks used for?
It is a mounting wall plate that drops the header mounting surface down so a double (twin) magnetic lock sits square on the frame. The plate itself is the bracket, not the lock, so you order it alongside the double maglock it supports. Alarm Controls makes them for two lock families: the AM3331 and AM3332 for 600 Series double magnetic locks, and the AM6331 and AM6332 for 1200 Series double magnetic locks.
2) Which drop plate do I order for a 600 Series double maglock versus a 1200 Series?
Match the plate to the lock series. For 600 Series double magnetic locks it is the AM3331 (1/4 inch) or AM3332 (1/2 inch). For 1200 Series double magnetic locks it is the AM6331 (1/4 inch) or AM6332 (1/2 inch). The 600 and 1200 plates are not interchangeable, so confirm which maglock is on the opening before you pick a part number.
3) What is the difference between the 1/4 inch and 1/2 inch Alarm Controls mounting wall plates?
Thickness, and that is what sets how far the maglock stands off the header. The AM3331 and AM6331 are 1/4 inch plates; the AM3332 and AM6332 are 1/2 inch. Pick the thickness that closes the gap between your header and the armature so the lock face and the armature meet flush; a plate that is too thin or too thick costs you holding force at the mating surface.
4) Will a drop down plate for a double maglock work on a single magnetic lock?
No. These plates are cut for double (twin) magnetic locks in the 600 and 1200 Series, meaning a lock body that spans a pair of doors. A single-leaf maglock has a different footprint and hole pattern, so you need the single-lock bracket for that series instead.
5) Does the drop plate include the magnetic lock?
No. The drop down plate is a mounting accessory only. You order the 600 or 1200 Series double magnetic lock separately, plus whatever else the opening needs (power supply, release device, wiring). The plate handles the mounting surface, nothing else.
6) What finish do Alarm Controls maglock drop down plates come in?
Clear anodized aluminum, US28. That is the same finish standard maglock bodies and header brackets are supplied in, so a plate stacked under a lock on a storefront or aluminum frame header matches the hardware around it rather than standing out.
7) Are these Alarm Controls drop plates rated for commercial openings?
Yes, they are commercial door hardware, sold for the same service as the 600 and 1200 Series double magnetic locks they mount. Typical use is a pair of doors in an access-controlled opening at a school, hospital, office lobby, or multi-family entry.
