SDC E1200 – Frequently Asked Questions
1) Will the SDC E1200 mag lock still let people out if the power goes down?
Yes, and that's the point of it. The E1200 is fail-safe, so cutting power drops the magnet and the door is free to swing. That's what makes it usable on an egress opening tied into the fire alarm, and the lock carries UL 864 certification for control units and accessories for fire alarm systems. Plan on the release being driven by your alarm interface, pull station, or egress device, because there is no mechanical override built into a magnet.
2) Does the SDC E1200 run on 12 volts or 24 volts?
Both. Voltage on the E1200 is field-selectable between 12VDC and 24VDC, so one part number covers either power supply and you set it at install. The board includes voltage and current spike protection. Nothing about it is battery powered, so it needs a dedicated low-voltage supply, and since it's fail-safe that supply has to be the one your fire alarm can drop.
3) What does door status monitoring on the E1200 actually report back to my panel?
Two separate signals. Door Position Status (DPS) tells you whether the door is physically open or closed. Bond Alert Status (BAS) tells you whether the magnet is actually bonded to the armature at full strength, which is the one that catches a door that looks closed but isn't pulled up tight. There's also an LED on the housing for status at the door. If your access control head end only takes one input, DPS is the one to wire; BAS is what you want for a monitored secure opening or an audited facility.
4) Can I use one E1200 on a pair of doors?
No. The E1200 is specified for a single swing door, so a pair needs one magnet per leaf and a double header bracket to carry them. If you're locking a pair, order two and size the power supply for both. A single magnet on a pair leaves the second leaf unsecured.
5) Do I need to mortise the door for the E1200, or does it mount on the surface?
Surface mount, no door prep. The E1200 magnet body mounts to the frame or header and the armature to the door face, using the interlocking quick mount assembly with an adjustable bracket for alignment. Self-drilling/tapping screws and machine screws come in the box. Wiring lands on a terminal block inside a wire access chamber, so you're running low-voltage into the header rather than through a door cord unless the opening calls for one.
6) Will an electromagnetic lock like the E1200 work on my opening, or do I need an electric strike?
A magnet is the right call when you don't want to modify the door or frame and the opening is fail-safe by design, such as a stairwell, corridor, or monitored office door. The E1200 mounts on the surface and needs no mortise work, and it releases on power loss. Go to an electric strike instead when the opening has to stay locked during a power failure, when the door already has a latching lockset you want to keep, or when the aesthetic won't tolerate a magnet and armature on the head of the frame. Magnets provide no latching of their own, so the door is held only as long as it's powered.
7) What else do I need to order with an SDC E1200 to finish the job?
The magnet ships with its mounting screws and bracket, but a working opening also needs a 12 or 24VDC power supply sized for the lock, a release device on the egress side (request-to-exit, push button, or motion sensor) and the fire alarm interface that drops power. On a glass or narrow top rail door you'll also need the appropriate mounting bracket kit, and on an outswing door a Z bracket or an L bracket. The E1200 itself is a single model with no option variants to pick, so those accessories are the whole decision.
8) Will the E1200 leave the door stuck shut for a second after it releases?
No. The E1200 has instant release circuitry that clears residual magnetism, so the armature lets go cleanly rather than clinging after power drops. That matters on an egress door, where a magnet that holds for a beat after the fire alarm trips reads to an occupant as a locked door.
9) Can I use the SDC E1200 in a hospital or school that requires fire alarm listed hardware?
The E1200 holds UL 864 certification for control units and accessories for fire alarm systems, which is the listing an AHJ looks for when a mag lock is tied into the alarm on an egress path. Combined with fail-safe release on power loss and BAS bond monitoring for verification, it's the configuration used on healthcare, education, and government openings. Confirm your local egress requirements for the specific opening, since delayed egress and stair reentry rules vary by occupancy.
10) Is the SDC E1200 housing metal or plastic?
Aluminum. The E1200 body is aluminum, which is what most integrators want on an exposed header application where the magnet is visible from the corridor. It also means you're not dealing with a plastic-shelled import on a lock that carries 1,200 lbs of load through the mounting.
