Fire Alarm Collection - Edwards Coded Pull and Bell (Take 2) - 6 of 7

[MrDeerEyes]

nothing will ever beat the gongs to signal a fire drill ..aaa childhood memories.. so much better thatn the horns and flashing lights

[Farenheit4051]

Actually, the coded pull stations are easier to identify than non-coded, handle-locking ones. The code they ring out represents the location of the station, so in a sense, the coded system was an early type of addressable system. A later format for coded systems would have non-coded stations each turn on a separate code wheel in the panel. This way, the signal would repeat itself instead of stopping at four rounds.

Also, coded stations were used up until probably the mid-1970's.

[MrWill1985]

I think Edwards kept that design when fire codes changed to where the pull station stays down. My high school had modern pull stations that look like the Edwards Coded pull stations except the pull handle was redesigned and the inside consists of a switch that moves when the fire alarm is pulled. And the signals were all integrities in code 3.

[MrWill1985]

I think one reason the pull switch has to stay down is also to identify which was was pulled since false alarm can be an issue these days and is a criminal offense. Ive heard of it happen many times.

[verdunman]

The glass rod would break so it makes it easier to identify.

[MrWill1985]

I think before the invention of pull stations remaining down happened people were trusted not to pull a false alarm. Unfortunetely it happens these days and modern alarms have a main panel in the building that shows where the system was activated from and the pull station remains down until it gets reset.

[MrDeerEyes]

i love the pull station, that is what we had in my high school

[DeltaPhi79]

The ones at my first school went like this (number of chimes in between pauses): 1-2-2-6-2..... odd isnt it.

[timrusty]

sounds like the old gamewell/edwards system i worked with in nyc a few years ago. we had a paper tape that punched out the station's code. very neat.

[brettman273]

That's fascinating; are you a fire alarm tech?

[timrusty]

i was a fire safety director. now on the fire dept.

[NikThaStik22]

Where could I buy one of these old pull stations?

[brettman273]

Ebay.

[NikThaStik22]

thanks. How much money? Estimate.

[brettman273]

No idea; you'll have to search ebay.

[HyperionGamer]

I've seen these pull stations in the Claim Jumper restaurant... and yes new construction.

[Biglele208]

Will you make ANOTHER video, that video showing the SILENCE and TEST features inside the station?

[brettman273]

There is not Silence feature as the station is self resetting. As for a test feature, there is a button inside that closes the contacts and makes the bell sound once manually.

[Biglele208]

the handle says: Pull ALL way down, and then let go

[cmarlow84]

I am wondering is there a meaning behind the codeing

the ding ding ding ding----- ( ding ) --- ding ding ding ding?

[brettman273]

The code identifies which pull station was activated, each station had a different code so that it could be determined where in a building an alarm was initiated.

[cmarlow84]

so some could be DING DING DING - DING DING - ding ding ding?

3 digs - 2 dings - 3 dings?

what identify which pullstation the 4 or the 1 single ?

[Heyde1979]

my old high school had the same system

[Heyde1979]

Brett you did a good job on this video very informative

[Jcc3278]

SOUNDS GOOD FOR AN OLD PULL STATION

[Biglele208]

Mohansic Elementary has this system

[Biglele208]

why dont you do the simplex in better quality?

[brettman273]

I will when i get around to it - i have since redone all of my collection and will be making new videos as soon as I can. It's just a hobby and i have other responsibilities.

[bmwguy145]

What is the hissing sound when you pull the handle?

[569E]

When you activate the station by pulling the handle down, you, at the same time, wind up a wheel within the pull station. The wheel has spokes on it that ring the code 4-1-4. Once the wheel is wound up by pulling the handle down, it will unwind 4 times ringing the code. The noise (hissing sound) you hear is the wheel unwinding.

[bmwguy145]

Thanks

[569E]

The old pull stations like these were coded e.g. 4-1-4. Each pull station had a different code. Having worked in schools for 30 years, we would have to listen to the code. The code gave the location of the fire. The first number indicated the wing of the building, the second number the floor, and the third number the location on that floor. Even though the pull station handle did not stay down, you always knew where the alarm was pulled

[brettman273]

The handles stay down in a variety of ways depending onf the make - masically the handle operates a button or switch, then catches on it to stay down. The station remains activated until reset, no need to hold the handle down. The clockwork station would have to be pulled again to restart the cycle

[rinker3]

what kind of fire alarm is the one on simplex fire alarm test 3

[Funnymaker2]

gay and gay

[brettman273]

That's nice, very creative too. I love how people flap their lips under the safety of the anonymity of the Internet. Please, do the world a favor; pull your lip over your head and swallow.

[Funnymaker2]

it is i mesan wtf

[Goldenrod636]

What was the license plates for?

[brettman273]

Covering up holes in the walls :P

[brettman273]

(Continued from above reply)

The action is simple - either a switch is activated or a button is opened - both of which also physically cause the handle to stay down. Usually the station must be opened and either the switch reset or a spring-loaded mechanism auto-reset. The Edwards pull in this video is much older and the handle does not stay down. Pulling the handle "winds" a clockwork that repeats a pattern 4 times.

[brettman273]

Finally, the handle in this case would have to be bulled a second time to re-activate after the cycle was complete. I am not sure how the older systems worked - it's possible that one could activate a continuous, or general, alarm at the panel after verifying there was in fact an emergency.

[travelplus1]

On the old Simplex Fire Alarm(The one that had a red handle) how did it stay down? How would th user know the alarm handle was pulled all the way down? Would the user have had to hold the handle until the alarm sounded?

Alson ont hhe one pulled her hwn the handel resets itself would the user pull it a second time since it wuld reset its self

[brettman273]

I'm not sure which alarm you are referring to. All pull stations since as far back as the 1950s (I'm not 100% sure when) have been required to stay in an obviously "activated" state so those in control could determine which station was activated.

[the06bug]

This sounds like the alarms on Degrassi Junior High

[Garner65]

so what happened to the simplex T handle and the ten inch bell/strobe combo?

[Xsk8r114]

ive seen a pull like this was there ever a time when had peace of glass kind of at the bottom.or did ink come out

[scooterbugs25]

I love this alarm, It reminds me of being in School 20 years ago, All but it rang slower and the bells were bigger..Same kind of pull station as well. We also had a pole that had a switch at the top and it had one of those small bells next to it. If you pull down the pole. the switch would flip and the bell would sing steady, It was not a single strike bell, it was not on the main fire alarm system. if that makes sence.lol

[brettman273]

Are you sure it wasn't the smaller version? These would really have no way to provide a continuous signal output. The smaller ones look the same but are just SPST switches.

[JLiza]

I don't really know. The handle stayed down, that was all I knew so it must have been smaller.

[JLiza]

I think my Junior High school had a pull like that. Except the alarm stayed in continuous.

[brettman273]

Was it maybe the smaller version? Those are basically just a switch; however, the larger ones could be used with a panel that detects any input and goes into alarm and ignores the repeating pattern..
