Edwards Coded Pull Stations | How do they Work? 

I really liked the analogy you used of it being a primitive form of an addressable system. Great video!

Learn something new every time I watch your videos. Keep up the good work S.E.R Safety!

Love those pull stations

Like the reverb in that garage!

Very nice. I like old vintage alarms like this

Edwards was and is so intelligent. Mind boggling this invention was made so many years ago!!

I giggled when Grant said "Thats self explanatory

There's an old Edwards coded station on display next to one of the tables at a local restaurant I used to visit quite often.

Really nice collection! and fun fact the high school I go too still has two of those American Time & Signal tbars

Great video! I couldn’t have said how coded pull stations work & their original purposes better myself. I’ve used this video to show some fellow electricians with fire alarm licenses how they function. Keep up the great work! 👍

These coded stations are what they had throughout my high school back in the 1970s. In those days they used bells so a 44 code would.be 4 dings onf the bell, a pause, followed by 4 more.dings. Back then I had a sheet that had all the stations, their codes, and location in the school. Anytime someone would.pull a box I'd count the bells and I'd right away know which stations was actuated and where in the school it was. In those days kids used to pull.a.lot.of.false.alarms and I got to know which stations were most frequently used to transmit a false alarm. In my teen years I was very interested in fire safety equipment such as fire extinguishers and fire alarm.systems. I even built.my.own fire alarm.systrm for my house. Back in those days it was not easy to get hold of actual alarm system components so I pretty.much had to build my system entirely.from scratch. I would have loved to have gotten hold.of some.actuall pull stations.

Nice demo Grant! Btw that pull station from 1966 is 54 years old, not 64, just so u know :).

literally right after i found interest in coded pull stations, this vid came out

Those "bumps" on the code wheel are actually called teeth, Andrew (NewAgeServerAlarm) could testify

2-5 is my favourite

Very cool! Thanks for showing

Can you use your simplex break glass pull station? Also how is the security system going?? Nice video!!

I like that coded pull station

Great job keeping it clean for something that old❤

Very nice grant!

Nice Grant

Nice video! Thanks for the information!

The coded pull station that is a loud alarm horn when you pull it the alarm will go eeeengk eeeengk eeeengk, eeeengk eeeengk eeeenk like that

My elementary school had these pull stations when i was in kindergarten and the teacher said that they were heating controllers

Hi love the vids❤️❤️❤️❤️

i love these videos

hey safety security alert

Nice pull station.

At 2:20 the coded pull station is like code 3

When you forgot to speak 0:55

a few questions. 1: do the alarms stop after the 4 rounds of code? 2 is there no panel? 3: does the pull station have the glass as an indicator of what station was pulled because the handle doesn't stay down like modern pull stations, or is it deter people from false pulling it? 4. is there some oversized backbox for them or do you just cut a hole in the wall or put it in sorry for so many questions. the only thing i really know about coded pull stations is that they exist

Cool!

great video. just got one of them myself. would like to see a video on wiring it up for demo. im guessing i need a relay in there somewhere as it seems to sound when the contact is open.

It is official Idaho schools are closed for the rest of the school year everybody let’s party

Mine never completes a coding cycle fully. Anyone else have that problem/ fixed it?

Edwards coded pull stations are like 270-spos

Nice demo! :)

Wow

That's just a big 270-SPO

It sounds like a air horn but lower

How would you reset it? Or do you have to just wait to it to go though the cycles

I have one of those pole station

This video is great 👍👍👍

Can you do the EST Integrity Chime Strobe Version?

Simplex 4050 is very LOUD! It just scared me to death and I jumped like a kangaroo!

Also how do I wire my 4050 horn I have the 6 volt version

woah is that a huge edwards version pull station?

Are these pull stations collectibles? I’ve got one and the red surface mount wall box with a UL from 1939.

I like that

Why would you want one vs two cycles,?

Does the coded pull station operate without wiring?

I imagine these pull stations are capable of handling 120 VAC power?

Can you video yous responding to a call in the fire engine

Can I have one of those old pull station please

When are you selling alarms again? Absolutely nothing on your ebay page and looks like you haven't sold in a while

I don't know why that horn is continuous that scared me last time I watch the video

Tell workers for testing

I want u to set off the alarm at YMCA

How much are they on eBay
