Detex ML-1548 – Frequently Asked Questions

1) Will the Detex ML-1548 mag lock release automatically if the fire alarm trips?
Yes, that's the whole point of a failsafe magnet. The ML-1548 holds only while energized, so when a Fire Life Safety System or a remote release cuts power, the magnet drops instantly and the door is free to swing. There is no mechanical latch to reset and no moving parts to bind, so release does not depend on anything but the power going away. That also means a power outage unlocks the opening, which is why these get paired with an alarm-integrated supply rather than being treated as a security lock of last resort.
2) How much space do I need on the door frame to mount a 1500 lb Detex mag lock?
Plan for a magnet body of 10.5 x 2.875 x 1.625 inches on the frame or header, and an armature of 7.4375 x 2.375 x .625 inches on the door leaf. The 1.625 inch depth is the number that usually decides it, since a shallow stop or a narrow header face won't take the body. Leave room around it for wiring access and future service as well, not just the footprint itself.
3) Do I have to order a left hand or right hand version of the ML-1548?
No handing to specify. The ML-1548 is non-handed, so the same unit works on a left or right swing, and you don't need to know the hand of the opening before you order. That also means one part number covers a mixed set of doors in a building, which matters if you're standardizing across a floor.
4) Does the Detex ML-1548 run on 12 volt or 24 volt DC?
Both. The ML-1548 takes a 12/24 VDC voltage sensing input, so it senses which supply it is on rather than needing a jumper set correctly at install. Built-in spike protection is part of the electronics module, so it tolerates the transients that come with sharing an access control supply. Wiring lands on a numbered terminal block, no wire nuts.
5) What is the difference between the surface and relock timer options on the Detex ML-1548?
Two configurations to pick from at order time. Surface is the plain unit: it locks when powered and drops when power is cut, with the timing handled by whatever access control you have upstream. The relock timer version adds an adjustable 0 to 30 second delay before the magnet re-energizes, which is what you want when someone badges in and needs a few seconds to push through before the door secures again. If your access panel already holds the relay open long enough, the surface version does the job.
6) Is the Detex ML-1548 ADA compliant for an accessible entrance?
Yes, the ML-1548 is listed ADA compliant. Because it is a magnet with no latch and no knob or lever to operate, there is nothing on the lock itself that requires grasping, pinching, or twisting. Note that ADA compliance on the opening as a whole still depends on your release device and operating force, not on the magnet alone.
7) Will an ML-1548 magnetic lock need servicing or adjustment like a strike or a latch?
No routine service. The ML-1548 uses an all steel magnetic core with no moving parts, so there's nothing to bind, wear, or fall out of adjustment the way a latch or an electric strike does. Surfaces are plated and anodized aluminum. For a property manager running a fleet of openings, that's the operational argument for a magnet over a strike.
8) What finish does the Detex ML-1548 come in, and will it match the other hardware on the opening?
One finish: 628 aluminum, clear anodized. That's the standard architectural aluminum finish, so it reads correctly next to aluminum storefront framing and next to closers and exit devices in the same 628. It will not match a brass or bronze opening. Since the unit is non-handed and single-finish, there's nothing else to specify on appearance.
9) Can the ML-1548 be mounted before the wiring is pulled?
Yes. The ML-1548 ships with an interlocking slide mounting plate and a peel-n-stick paper template, so the plate can go up and be located off the template either before or after the wiring is run. That decoupling is what saves time on a retrofit where the low voltage isn't in the header yet. The body then slides onto the plate and lands on the numbered terminal block.
