This elevator is more from the 80s. The Dover buzz is on 90-91 elevators, and this elevator has the bird chirp. Also the extremely delayed time on the upper floor
I've never seen a Dover impulse elevator with a floor indicator time like that before. Typically when I see a Dover impulse elevator it has been buzz for a floor passing time.
+Jordan Lowe ElevaTours Canada Yep, that's how the relay controllers do it. Each number turns off after the elevator passes that floor, and then the next indicator comes on. This is especially common on Impulse traction elevators. Many of the relay controlled ones have a chirp rather than a buzz, but this is particular one is a very uncommon chirp sound.
Looks like the Courtyard Marriott by the Convention Center in Portland with also Impulse fixtures, it's also a 6 Story HIGHDRAULIC, Same Motor, same starter, & same Chimes!! 😁😁
