School Fire Drill - 4/18/23 

Man again i love the sound of those older simplex alarms.

i actually got to pull the fire alarms at my school too!!

I’m thinking the panel probably was originally a 4100 classic based on the old hardware and field devices but now it has a 4100ES cpu and display operating as the head end to the system. Cool the new stuff was designed with be compatible with the old analog hardware in mind. Not sure why the panel doesn’t have the new 4100ES stickers. They come with the upgrade kit(s). My old highschool’s 4100U panel was also rigged to the PA system and would cause the PA to play a special tone until the NACs were silenced or the system was reset.

Lmfao the principal did not know what he was saying 6:13 "it'll say normal so it still isn't done yet", should've told him all you have to do is press C/Exit on the keypad and it'll say normal. it takes 60 seconds for it to go to a "Normal" screen if you do not clear that "Reset Complete" screen

Hey SirenDude1003, Cool😎 Sound Of The Simplex 4903 And 9838

good thing they test them, in my middle school one of the smoke detectors went crazy and set off the alarm twice!

You Got To Pull It But Not Reset It.

Never did I expect to be recommended a niche such as alarm systems

Finally some fire alarm content from you! Great video, and I love those older Simplex alarms

Never seen fire doors that swing like that lol

Same

Those simplex 4903+9838 combos are so cool! I also have one more month left of high school. My school has EST Genesis speaker strobes tho and they play the boston tone.

nice 4903s and 9838s whats the panel

Over 5 minutes to evacuate a high school? That’s pretty scary…

cool

Whats the panel? Probably a 4100U or a 400X

Is that a 4100 or 4010?

Those doors are not ADA complainant and a person with walking problems, or chair bound can not get though the doors to safety and would die.
