Music to my ears.

[@brianthetowerguy979]

I love this video

[@SomeDudeWithAnExitSign]

Don’t see much 4002s in service anymore. I have only seen like 3 4002 systems so far.

In my time of doing door dash for two years I came across a lot of 9838 fire alarms on various light plates came across a couple 9833s even 9840s and majority of the systems where 4002s except one was a 4100 but the old alarms still remained

Beautiful!

[@RaccoonAlarmsVosgra]

Those 9838s sound like 9833s

[@ImpyLane]

What's the difference?

[@RaccoonAlarmsVosgra]

The 9838s and 9833s are a little different from each other

[@RaccoonAlarmsVosgra]

​@@ImpyLane they have the same mechanisms but the 9833 sounds brassy and is louder. The 9838 is basically a low profile 9833 but mostly is quieter than the 9833

I’ve seen a 4002 system at a eye doctors office with 2903 fire alarms. That was located in Bellaire, Texas. I don’t know if they still have these any more
