Sounds like a floor washer buzzing

I started to get into fire alarms when I was 8 I had one in Dallas but misplaced it

We had the double projectors (Simplex 4040s) at my high school. They're much louder if you're on either side of it, than if you were directly right in front of them.

When I was unplugging the panel, I accidentally unplugged the power strip that goes to the computer.

We had those same pull stations at my middle school. My second elementary school (Gr. 4-6) were also "Chevrons", but they were IBM/Simplex (Red & white).

u know i relly like your videos cuz you know and explain your alarms verry well and you have a rather interesting collection of alarms wich i like =)

Simplex 4040s are one of the loudest fire alarms ever

Grandmom 's lamp buzzing

The horn sounds louder when it's on battery power

It almost sounds like a Simplex 4040

I think that it's louder to you since the sound is projected to you.

Thanks!

Projectors do actully make it a little bit louder

Yeah, Faraday bought out Couch in 1985 and continued to manufacture the chevron-series.

Sounds like grandmom's lamp

That 4051 Sounds Like A 4050

Seems much louder when on backup power.

the remote strobe is probably a 4904-9137

My 4040 is 120 VAC o.O (It's a Federal Signal Vibratone 350)

I am getting a 4251-1 pull station. Any advice? I don't have the allen rench.
