Current Status: call buttons operational, call light on first floor broken (120V M5)
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.
