[Libs-Or] Security gates with audible whine

[Serenity Ibsen]

Hello everyone, do you or anyone you know have these electromagnetic (not
RFID) security gates?

http://www.demco.com/webprd_demco/html/landing_pages/circulationtech/pdfs/SecGates_SpecSht_EM.pdf

We're considering buying a new gate system, but are worried that they will
have an audible operating sound (hum, whine, etc.), so it would help if we
could "test drive" yours.

If you have a newer EM system that is different than the one above and have
information about their operating noise, I'd love to hear it.

Thanks!
Serenity
