Video 2 of the same building, after I pull a pull station, I trip the smoke detector in the elevator lobby to test elevator recall. As you see, the detector went into alarm, but the elevators did not stop operation and recall to the ground floor, which was a deficiency. After all was said and done, we found out that the elevator relay points were backwards, so this smoke detector actually recalled the elevator bank on the other end of the corridor. And vice-versa. When the detector activates, the elevator buzzer would normally come on and the fireman's hat would light to indicate that the elevator is being recalled to the ground floor. Coincidentally, the new revisions of UL actually say that the term "elevator recall" is not accurate, and the new technical term is "elevator capture". Dunno why, literally, "recall" is more accurate,

Perhaps the relays were going bad since he did say that each was calling the opposite elevator unless this is a brand new building

I hate testing elevator recall. The building owner never has the keys, and elevator companys wont share. This realy should have been caught at the acceptance test. But programing happens it should have been an easy fix for the tech.
