It's so awesome to see old original systems still in service. I love the aesthetics of 80s and 90s systems. Especially Simplex

When I lived with uncle he looked after a middle school android the same size, there was rooms that had to be alarmed as 💻 was in them, sometimes I'd have to reset the boilers as they trip on none flame up. It had a large stagings Hall and three floors so unlocking everyday was a task in it self.

Simplex makes some of the most interesting yet robust equipment. I mean that panel has to have lasted 30 years or more and still works. As for the pulls, they’re not an original Simplex design or manufacture (they’re an obvious outsource) so I wouldn’t really put the blame on Simplex for the bad pulls. However, I feel like this particular install would’ve been 100x better without that model of pulls (I would’ve used 2099 T-Bar style pulls).

25:21 the one red sour patch kid has been lonely for some time. How long do you think its been there, I think 30 years

it would be funny if you got a hoverboard to ride around the school while testing the alarms.

I do enjoy your videos, I used to watch many fire alarm videos on KZfaq when I was younger. Sadly most of the people (myself included) no longer make fire alarm related videos. On the issue of how the conventional panel is able to detect multiple detectors on a single zone being set of without being reset, maybe the panel can detect the increase in current draw that each detector creates when it is set off. Just a educated guess, as I know many conventional systems use the current draw of a detector to determine an alarm state. Also ever accidentally set of a fire suppression system, I heard a story where some random person set of a inert gas fire suppression system in a server room at my work place due to the panel was beeping outside and they pressed the manual release button on the fire suppression panel outside the room. Was before my time.

Those are some very unusual pulls for Simplex; definitely of Amseco manufacture as Mircom and Notifier had those exact same pulls made for them back in the day save for that very very unique contact switch inside. As you said definitely wouldn’t have too many kids pulling these with all that resistance on the handle. The bells however sound super strong and healthy.

We're getting ready to replace a bunch of 270s (probably with Notifier 12Ls)... If I had a nickel for every time I've flipped off a 270, I could have retired 10 years ago... Thank God I've never had to deal with those old tight ones, I'd likely have just burned the damn building down instead...

Ah yes, vintage simplex, before JCI or Tyco bought them

Love these older 4100's.

On simplex conventional panels the zones get power dropped after every alarm to reset the smokes on walk test. That’s why multiple could go into alarm. I believe it can also read the voltage load to allow multiple detectors to alarm at once

Alarms: Simplex 10 inch Bells

Great video.

Love to see that simplex system

The buzzer in that panel is on its last legs.

what type of smoke pole is that looks nice

Fire alarms replaced in 2009

What pulls did you end up replacing the defected ones with?

Whoever at Simplex designed those pull stations should be forced to spend an 8 hour shift of doing nothing but pulling and resetting them and see how many times he or she screwed it up.

At least that system is not as bad as the system at your old Middle School!

Good have to get on

why the fire alarms in your schools are so antiquated. The fire alarms in the schools in the US have been. converted to buzzers. with strove lights so of the public places in the US even Walmart's who in the us who have Bosch voice activated fire alarms & some have Symplex some have buzzers

Old simplex! I think there should be more strobes

Gotta get that old thing out and put in a 640 😎

All those pull station should be replaced with a newer simplex pull stations be lit easier and also that pa in the 4100 panel should be replaced as well or replace the whole panel and put in a new one because simplex discontinue making parts for those panels.

are both panels tied in

Why don’t you guys ever do silent walk test. Wouldn’t that be easier?

Whats to horn noise

First Comment :D

Why Are The Hallway Lockers Open Are They Cleaning The Lockers Out Or Something

System sensor 1400 smoke detector

I’m surprised it’s conventional as the 4100+ could be a conventional or addressable panel.

The good on

The thing where you can stack alarms must be a programming issue.

That panel should be addressable, as I dont believe thosr 4100s were conventional.

Dude! Why did you delete my comment?!!! did i offend you?!!
