Detex MS-2049F – Frequently Asked Questions

1) How does the Detex MS-2049F magnetic switch mount on a door, and does it need to be recessed?
The MS-2049F is the flush mounted version, so the switch body goes into the door edge and the magnet into the frame (or vice versa), sitting level with the surface rather than standing proud of it. That means drilling and prepping both sides of the opening. If you cannot cut into the door or frame, a flush switch is the wrong choice for that opening and you want a surface mounted contact instead. Detex publishes the MS-2049S in the same MS-2000 family as the surface counterpart.
2) What does Form C mean on the Detex MS-2049F door contact, and can I wire it normally open or normally closed?
Form C is a single-pole double-throw contact: one common, one normally open, one normally closed. You pick which pair you land on at the panel, so the MS-2049F works on a normally closed supervised alarm loop or on a normally open input without ordering a different switch. That is the practical difference from a Form A contact, which only gives you one state.
3) Can a magnetic door switch be pried off or defeated from outside once the door is closed?
On the MS-2049F the mounting screws sit where the door covers them, so with the door shut there is nothing to get a driver on. Someone would have to open the door first, which is the event the switch reports anyway. That is the reason to spec this one over a plain surface contact on a retail back door or a stock room where tampering is the real threat.
4) Will a magnetic contact keep false-alarming on a door that does not always pull up tight?
Loosely closed doors are the usual cause of nuisance trips, and the MS-2049F is built to hold state through that condition rather than chatter. It also carries a rating of over one million operations under load, which is what you want on a door cycling all day rather than a perimeter door opened twice a week.
5) Is the Detex MS-2049F rated for commercial use or is it a residential alarm contact?
Commercial. It is a heavy duty switch with potted internals to guard against shock and moisture, rated past a million operations under load. That combination is aimed at hospital corridors, school exits, warehouse doors and municipal buildings, not at a house alarm where a light duty reed contact would do the job.
6) Can I use the Detex MS-2049F to trigger an exit alarm or a horn directly instead of running it into a panel?
Both are supported. The MS-2049F works as a position sensing device feeding an access control or alarm panel, and it can also switch an audible or visual alarm directly, since the Form C contacts are rated for switching under load. Which way you go depends on the current your sounder draws, so match that against the switch capacity before you wire it in line.
7) Can I put a Detex MS-2049F on a window as well as a door?
Yes, the switch monitors window openings as well as doors, as long as the sash and frame can take a flush prep and the two halves line up when closed. Same wiring either way. On a window the tamper benefit still applies, because the screws are covered when the sash is shut.
8) I need to standardize door position switches across a whole facility. What else is in the Detex MS-2000 series besides the MS-2049F?
The MS-2049F is the flush model. Detex also publishes the MS-2049S, MS-2049SC and MS-2049SI in the same MS-2000 line, which lets you keep one family across a building where some openings take a flush prep and others do not. Keeping the series consistent means the same Form C wiring convention at every panel input.
