Detex MS-2049SC – Frequently Asked Questions

1) What does Form C mean on the Detex MS-2049SC magnetic switch, and can I wire it normally closed?
Form C means the MS-2049SC gives you both a normally open and a normally closed contact off the same switch, so you pick the one your panel wants. Most alarm loops run normally closed so an opened door or a cut wire both trip; a normally open leg is there if you are triggering an audio/visual device instead. The contact configuration is set at wiring time per the application.
2) What is the difference between the Detex MS-2049SC and the MS-2049S or MS-2049F?
They are variations within the same MS-2049 family, each with its own installation sheet: MS-2049F, MS-2049S, MS-2049SC and MS-2049SI. The SC is the flush surface version with an integrated conduit connector, so the wiring leaves the switch into conduit rather than a loose lead. If your spec calls for conduit-entry wiring at the frame, SC is the one to order.
3) Can a magnetic door switch be used to trigger an exit alarm, or is it only for a burglar panel?
Both. The MS-2049SC works as the sensing device for door and window opening detection, as a trigger for wall-mounted exit alarms, and as a direct switch for audio/visual alarms. That last case matters: because it carries a real switch rated for over a million operations under load, it can switch a connected device directly rather than only reporting a dry state to a panel.
4) How is the MS-2049SC protected against someone unscrewing it to defeat the door contact?
The mounting screws sit where the door covers them, so with the door closed there is nothing to get a driver on. That is the whole tamper story on this switch, and it is why it gets specified in retail loss prevention and government work where a surface contact would otherwise be the weak point in the loop.
5) Will a Detex MS-2049SC hold up outdoors or in a wash-down area?
Its internal components are potted, which protects the switch against shock and moisture. That is a sealing of the electronics, not a stated outdoor rating, so treat it as suited to damp and high-vibration commercial openings such as industrial and loading-area doors rather than as a listed weatherproof enclosure.
6) Our doors sit a little loose in the frame and our old contacts nuisance-trip. Will this switch help?
That is one of the design points. The MS-2049SC is built to reduce false signals from loosely closed doors through its magnetic detection and switching action. For a property manager chasing repeat false alarms on sagging or weather-stripped doors, that plus the million-plus operation switch rating is the reason to move off a light-duty residential contact.
7) Is the Detex MS-2049 series a commercial-grade door contact or a residential one?
Commercial. The MS-2000 Series is classed as commercial door hardware and the MS-2049SC switch is rated for over one million operations under load, which is why it shows up on hospital, school, retail and municipal openings that cycle all day.
8) What do I need to know before wiring in a Detex MS-2049SC?
Kill power first, confirm the circuit current is within the switch capacity, then run the leads through the integrated conduit connector with wire gauge suited to the load. Decide at that point whether you are landing on the normally open or the normally closed leg of the Form C contact. Mount it so there is still clearance for wiring access and later service, then test the alarm function end to end with the connected panel or alarm device.
