@monkeyflower @deviantollam I was curious about this (as its not a thing in UK/Europe), but apparently it is common in parts of USA as well.
The alarm button is supposed to connect to a human operator and activate the loudspeaking telephone in the lift and in newer ones a screen. If the person with the emergency is hearing impaired they can use the screen messages and the yes/no button to communicate with the emergency operator.
@vfrmedia @monkeyflower One tiny iota of clarification: the emergency call button (out of frame in that photograph) would have the functionality you describe.
The alarm button (visible in that photograph) is often merely a local alarm that makes noise in the hoist way.
Ah, this is slightly different to what I've encountered in UK (I worked on the maintenance team in a senior home and had to wire up the telephone circuit end of these things) - over here pressing the alarm button (there is only one) both makes the noise *and* activates the autodialler in the lift telephone, which either goes to a control centre or (in the case of the site I worked on where it had 24/7 staffing) dials an emergency extension on site (I had it going to a ring group which alerted all on duty staff)
Incidentally modern lifts (in common with the rest of Europe) now often just have 1, 0, -1 rather than 1, G, LG etc..
@monkeyflower I love the idea of "yes, and" 😁👍
But you're on the right track... https://defcon.social/@deviantollam/115324312643100538
Attached: 2 images Time to see who's been taking notes in class, kids. (I did a video about this same thing last year) 😏 Who can tell me why this elevator might be asking you "Yes" and "No" questions that you could answer using the buttons seen here? UPDATE: OK, It's been quite some time since I posted so I'll share the link to the answer here for anyone who happens across this toot in the future... https://youtu.be/jHnSRkau9yY
