Another Flashback To The 80s and 90s [Fire Alarm A/V Test] (12-11-2023) 

we got those exact same alarms in my school

You just can't beat vintage stuff. Will ALWAYS love that sound!!

It blasts at different tones haha

@ZDC2002 As a person who has been born with a visual impairment his whole life, and developmentally delayed, I look back now in my past 34 years on this earth, and think to myself, these alarms weren't bad. the alarms in this video. alarms are my biggest sensory overload. they are insane. question for you brother, what model of alarm is this? i look back and tell myself, these particular alarms, especially outside my old elementary schools i attended growing up, were loud, but weren't as loud as those shrill whistle fire alarms or those loud school bell alarms. but let me know what model of alarm is this? i appreciate this sound over the 3 chirps, ever 2 seconds. and those being the loud recess whistle type of alarms. i despise those. but this type of alarm that goes on and on and on, i appreciate it. as a musiain, i noticed that the alarms in this video are in certain keys. musical note keys. one of them in "A", one in "G" sharp, a note below "A". at the beginning of this video, one of the alarms were in "B". very cool stuff if you ask me my friend.

what panel

Sounds like there may be a bad power supply or NAC circuit.

1:14 EXACTLY what a couple of horns at my elementary school sounded like

these 4903-9101s were the same but installed upside down when i went to the ut physicians parking garage in downtown houston tx

Best effective alarm ever for being heard and evacuating retirement homes.

One of the 9838s sounded like a 4903

*looks outside my apartment door* thise mechanical horns are here...

One thing I will never understand is why they put such loud horns in tiny portables we had those in portables when I was in school they were so loud that it hurt our ears my ears would ring after we exited the portables just to give you an idea on how loud they were I can listen to aircraft afterburners with no earplugs and my ears weren’t even effected I have a very high tolerance of loud noises if it bothers me you know it’s way too loud it takes a lot to make my ears ring they don’t need those loud horns in portables they are way too loud all they need is a strobe

My now former high school has these alarms. They were switched to temporal code at some point but they are a lot easier on the ears than continuous horns

I used to be scared of the sound they make

This sets me back to elementary school!

This on continuous sounds like a war zone.

That’s what I had at my old elementary/middle school. My high school just has Spectralert advances. :(

Very W System wished that 4903 worked

I have that alarm but with a different strobe.

Those 4903 hornstrobes definitely have problems. I also remember when I had internship at a retirement apartment complex, it also had those same mechanical horns matched up with the same strobe plates as well as strobe plates with the horn only versions of 4903's mounted on. Though I never heard them in person, not even that time a resident's microwave filled one of the apartments with smoke, I remember how bad that smelled.

My high school has Edwards integrates on continuous

This video reminds me of my old kindergarten days
