06/04/2021 Bell Test 2 (Simplex 4100ES)

Bell test number 2 from today, and as luck would have it, it actually involves bells! The system here is a 4100ES, however it's obviously not original to the building as all the devices outdate it. It's also set up as a zoned system, and not an addressable system. I was expecting the bells to sound in continuous, but to my surprise, they actually sounded in code-3! The strobes are a bit of a mixed bag, as most of the ones on the first floor are coded to code-3, however the ones in the basement and sub-basement flash normally. The strobe light seen at :43 and 1:00 is non-functional. We also found three defective bells. The defective strobe will be replaced with a new 4904-9178 strobe, as Simplex still manufactures it. Because Simplex no longer makes the 2901 bell series, Wheelock MB-G10-24s will be ordered to replace the defective bells.
