Alarm Controls 1200D – Frequently Asked Questions
1) Will the Alarm Controls 1200D hold a pair of doors, or do I need two separate mag locks?
The 1200D is a double magnet unit built for a pair of doors, one magnet per leaf, each rated 1200 lbs of holding force. You order one 1200D rather than two singles, and the two magnets share the header run. For a single opening you want a single-door mag lock instead.
2) Does the 1200D mag lock unlock when the power goes out?
Yes, it is fail-safe. Cut the power and both magnets release instantly, with no hysteresis holding the door. That is inherent to how an electromagnetic lock works, and it matters for egress: any opening on a 1200D needs its release tied into the fire alarm and egress devices your local code requires, because the door is unsecured any time the supply drops.
3) How much header space do I need to mount an Alarm Controls 1200D?
Each magnet body measures 21 x 2-7/8 x 1-1/2 inches, and the matching armature is 7-1/2 x 2-3/8 x 5/8 inches. Two magnets go up on the header, one over each leaf, so you need clear header depth for a 1-1/2 inch deep body across both magnet runs. The armature mounts on the door face at the top rail. An E-Z mount header bracket and drilling template come with it, along with self-drilling TEC screws, so no special tools are needed.
4) Can I monitor whether the doors are actually locked with the Alarm Controls 1200D?
Both. Each magnet carries a bond sensor and a door status sensor, plus bi-color LEDs on the housing that show the magnet is powered and the door is drawn up tight. The bond sensor gives SPDT 3A relay contacts per magnet, so you can land them on an access control panel or alarm input and tell a door that is merely closed from one that is genuinely bonded. That distinction is what stops a leaf that is resting against the stop from reporting secure.
5) I need a magnetic lock with bond sensing and door status monitoring. Which options carry that besides the 1200D?
The Alarm Controls 1200D includes a bond sensor and door status sensor plus bi-color LEDs to signal a powered and securely locked door, with SPDT 3A relay contacts on the bond sensor per magnet. The Schlage M390RFK is rated 1500 lbs holding force with a door status monitor, magnetic bond sensor and relock time delay, and is a direct retrofit for the Locknetics 390+. The Dorma EML310 BA DP is a single door 1500 lb unit with bond alert and a door position sensor, and the Locknetics MG Series is available in a monitored model.
6) Does the 1200D unlock on a fire alarm, and which alternatives are fire rated?
The Alarm Controls 1200D is fail-safe, so the magnets release when power is dropped, which is how a mag lock ties into a fire alarm release. The Dorma EML320 double door 1500 lb unit is fire rated and electrically locked fail safe, as are the single door Dorma EML310 with door position sensor and the EML310 BA DP with bond alert. For an institutional opening where the fire rating has to be stated on the submittal, those Dorma units carry it.
7) Will the 1200D mag lock work on an exterior door in cold or hot weather?
Rated for interior or exterior use over an operating range of +14 to +131F (-10 to +55C). Non-aluminum parts are plated against corrosion and arc suppression is built in. If your opening sees temperatures below 14F, that range rules it out, and a weatherproof mag lock such as the Locknetics WMG Series is the direction to look.
8) Do I have to specify a finish on the Alarm Controls 1200D, and what are the choices?
Two finishes: clear anodized (US28), which ships as standard, and DURO Duranodic (US 40), which has to be called out when you order. Voltage is a separate required selection, 12 VDC or 24 VDC. Nothing else has to be specified.
9) Does the 1200D magnetic lock work with my card reader and access control panel?
Any access control system can drive it. A mag lock is a dumb load, so the panel or reader just switches the 12 or 24 VDC feed to the magnets. There is no proprietary protocol and no controller to match. The bond and door status contacts run back to the panel as dry inputs.
10) Is a mag lock like the 1200D the right choice, or should I be looking at a shear lock?
A surface mag lock like the 1200D mounts on the face of the header with the armature on the door, so it is visible and it needs header depth for a 1-1/2 inch deep body, but installation is straightforward and it releases instantly on power loss. A shear lock such as the ROFU 8031-002 mortises into the header and door top rail so nothing shows when the door is closed, and it holds 2200 lb. Pick the surface mag when you want the simpler install or cannot cut the frame; pick the shear when the opening has to stay clean-looking.
11) Is the Alarm Controls 1200D rated for commercial use, and does it run on batteries?
Built for commercial openings, and it is a hardwired electronic lock, not a battery device. It needs a constant 12 or 24 VDC supply, which on a double lock means budgeting roughly 1.01 A at 12 VDC for the two magnets. Plan for a supervised power supply with battery backup on the supply side if the opening has to stay locked through an outage.
