Top braille: fire alarm
Bottom Braille: push and pull
If I’m not mistaken.
What is the history of the “WHEN BELL RINGS DIAL 911” compliance signs? Was this because old fire alarm systems lacked the ability to dial 911 on their own due to limited technology? What dictates the use of such sign? Is there some sort of safety code surrounding this that mandates their use?
I have seen these signs in a variety of applications from indoor malls, factories, offices, or more unusually on the exterior of new-ish single family tract houses. (seemingly built with fire sprinklers). Always with that iconic fire alarm bell.
Real easy one here.
What does the Simplex 4903-9219 alarm share its horn with?

That fire alarm bell is not actually an active device. It is a motor bell that sounds when water flows through the sprinkler pipe. So yes, the sign says to call 911 because it predates dialers. I am unfamiliar with the law that would dictate these signs.

Actually, there are FACP-powered waterflow alarms that also have the sign, such as this: https://www.youtube.com/watch?v=-wMFgnGcIms Most modern installations use such setup.
Let’s stay on track here with the questions

A: 2002 when the 4100U was released
T or F: The early model QuickStarts had a mechanical buzzer piezo before switching to the more recognizable electrical piezo?
Hint: You’d be surprised 
I have a simplex 4903-9418 from 2000 and I really can’t hear a difference with the sound except the slight difference in the pitch, but I’m going to go with true.

I’m talking about an Edwards QuickStart panel. And yes, it is true. The models with the buzzers were in The very early versions of development, and only a few were released to use in service.

A: 1997 IIRC.
Q: What is the proper way to run fire alarm wiring above a drop ceiling?
A: I believe you have to run the cables on the suspenders that hold the drop ceiling frames if IIRC from seeing some diagrams
Q: when did EST introduce the EST3?
BTW, lets keep this topic going, hopefully until it gets pinned
