Frequently asked questions

Why is the MS21 is causing the door to cycle?

There is possibly a grounding issue. Ground all conductors in the same cable as the power conductors. Be sure to use shielded cable and verify that both ends of the cable are grounded.


Can the MS21 activate devices other than doors?

Yes. Always review power calculations to verify amperage and voltage limitations.


Are BEA touchless switches compatible with all brands and types of doors?



How is the MS08 wired?

The MS08 has a 4-wire configuration:
red and black = power
white = common
green = normally open
spare terminal = normally closed (if needed)


How do you adjust the relay hold time?

The relay hold time potentiometer (POT).


Is there an audible alert?

MS21 = yes (DIP)
MS08/09 = N/A
MS11 = yes (jumper)


Is there a toggle feature?

MS21H = N/A
MS08/09 = yes (output switch)
MS11 = yes (output mode jumper)


Do I need a special type of wire for any of the Magic Switch products?

Only the MS21 requires shielded wire. All other Magic Switch products (MS08, MS09, MS11) require a standard grade, 4-conductor cable.


Is it possible to make a Magic Switch wireless?

Using the 900 MHz Retrofit Transmitter, a Magic Switch can transmit wirelessly but still requires power to be hard-wired.
