Use the elevator buzzer if you need assistance, or if the call buttons do not work.
Current Status: call buttons operational, call light on first floor fixed (120V M5). Whole system sometimes does not realize it is not in operation, at which time the call buttons do not work. Only known fix for this is to get inside, ride it to another floor, and exit normally. Sometimes you have to do this a couple times.
July 27 2010 Test report:
1st floor call button normally closed contacts were impacted with nonconductive dirt. Cleaning is performed with simple white paper, not anything else. Please, if you ever clean these call button relays do not use abrasives, they shorten the life of the relay. Also be sure to take voltage precautions since the switch has 120VAC across it.
When any call button doesn't work, the whole system doesn't work. Is that what is called 'failsafe'?
There's a PDF for an elevator test plan uploaded to the Noisebridge wiki for the elevator. Test monthly.
