I grew up with bells and electro-mechanical horns. My kindergarten classroom had a Simplex 6 inch bell and hallway had Simplex 10 inch, all on Simplex 4080 light plates. Well, pre-k was a Wheelock 34T on a Simplex 4080 light plate. School bells from K-5th grade were 10 inch gongs. From first through fifth grade had Wheelock 7002T and 7001T. Replaced with System Sensor spect alerts. Middle school had GS-895B-201...I think and 270SPO pull stations. Replaced with Wheelock NS. No clue what the pull stations are now. High school had 10 inch grey bells for burglary and single stroke bells and vibrating bells were used for class change in high school. Pull stations in elementary school, daycare, and high school were BG-10...all replaced with BG-12. They were like music! I went back to visit my high school after I graduated and ALL of the bells were all gone! Class change bells were converted to P.A. bells (a pre-recorded tone would play over the P.A. system) and the burglar alarm system was converted to a silent alarm. And, my elementary school was converted to P.A. bells and System Sensor specter alert classics horn/strobes. I miss the old electro-mechanical horns and bells that I grew up with. Today's alarms are just simply awful.
Hands down, without a doubt the 439D gets my vote. It is not only louder but has a far better sound compared to the motorized MB-24s. A little history on the 2 bells: The 439D first began it's life in Canada in the 1950's under the Adaptabel name. Then in around 1969 "Edwards of Canada" (based in Owen Sound Ont) began using the "Durabel" name for it's continuous vibrating bells only. The adaptabel name was only used on the special application/single stroke bells thereafter. In 1984 Edwards of Canada renamed and rebranded the Durabel under The 439D ident and shortly after outsourced it's product line to it's parent Company located in Norwalk Connecticut (Edwards USA) In 2001 Edwards began phasing out it's higher quality 439D line to the cheaper and lower quality MB-24s which were then made in China by what was then "Amseco" but is now owned by Potter Signal Corporation. Potter now makes bells for Edwards as well as a number of other manufacturers (Mircom Siemens, Notifier) The 439D bells were available for a few more years in Canada but have since been succeeded by The MB-24 and are generally only used for replacements in existing bell based systems and are rarely featured in new systems today (with electronic signals now taking their place) There my friend; is the history of the Edwards Fire bell in Canada.
Thanks for the interesting history I love stuff like that I had always thought that the durabells came out before then as they were and still are some in my old middle school which was built in 64 but I guess they must not have been original like I thought they had been
Having grown up in and attended school in the 70's and 80's I got a front row view of Edwards entire history through that time. The Edwards shield on the pullstations also had an update in 1984 from the 1950's version to the version we still see today. As to when the Adaptabel bells in Canada went out of production; I'm not really sure but I believe it was in the 2000's. In my office at work we have the "Notifier" equivalent of the MB-24s and they sound and look exactly like the Edwards branded ones.
I’m Canadian, and my high school was built in 1956, and the original fire bells were Adaptabels i believe, but they were replaced around between 1992-1996 with 439Ds we still have today. Then, in 1998, there was an addition to the school, and they had to tear the front part of the school down for the addition. Most of the bells that were installed in the addition are Edwards GS MB10-24s. There’s also an older Simplex 2901 bell in a separate band room at the school. Not sure when it was installed, but it was before the 439Ds. Today the school has half Edwards GS MB10-24s and half 439Ds.
I have a 6" Adaptabel from that same era that I use as a custom doorbell. By far growing up those bells were my favourite as they still had the Original 1940's Edwards shield logo on them. A rarer and rarer sight on bells these days.
In the first test you did, I noticed that after the bell stopped ringing it took a while for your camera to readjust its automatic level control, so the loud sound of the bell must have caused the ALC to pump way down.
@@nics-systems-electric Adaptabells were mostly single stroke, though they did make some vibrating models for reasons I’m not sure of. The durabell was basically the predecessor to the 439D series.
@@CJ9899 thanks I’m not sure why they didn’t just continue the durabells they seemed fine to me I’m not sure when they stopped making them but I’d guess as soon as they started making 439D’s?
Sound difference levels of the MB-10 and the 439D at 10 feet and in the room MB-10: 27.9 439D: 20.7 So it appears that the sound of the 439D dropped by 20.7 decibels when it was in the room because the sound that it makes is more cleaner than the MB-10 espically on Filtered DC making the sound more better at traveling through walls than the System Sensor P2R In the last video. But the reason why the 439D's sound difference levels came up as the same as the MB-10 in the last video because in this video the MB-10 was tested in the room where the couch is and in the last video it was tested on a demo board touching the bathroom door because distance can affect sound pressure loss which must be why the MB-10 in the room dropped by 27.9 dB instead of 20.7 dB (7.2 difference) and I'm thinking if the System Sensor P2R was tested in this exact same spot then it will drop by 22.7 dB because it's farther away from the spot in the last test making the sound pressure level drop a lot more from this difference. Here's how these signals are ranked on sound penetration #3: MB 10-24 #2: System Sensor P2R #1: 439D
For this demonstration you don’t need an end of line resistor but for a system that is how it monitors the circuit if it doesn’t sense the resistance that means the resistor at the end of the line has been severed from the circuit somehow whether somethings been cut or disconnected it’s a way that the panel can tell if the circuit isn’t intact which could mean devices won’t work
Motor Bell uses a motor that have some sort of gearing and a off centre pin commonly that will move back-and-forth pushing a striker into the gong and a vibrating bell is kind of like a solenoid that moves back-and-forth with electric magnetic fields of a coil
Yes major problems but this video was already scheduled anyways I don’t have any issues though only if you’re with Rogers no cell service or Wi-Fi which also means cash and credit card only for buying things it’s been going on for over 24 hours for many people which is a pretty big deal when millions of people don’t have cell service

yay fire bells! I love these videos!! Thanks Nic!
Me getting so happy to get the notification if a ne video that u posted
Me to
There are loads of bells in the UK, in fact every school I've been to used bells as a fire alarm signal
That’s good
We americans get cool mechanical horns and strobes,
@@justmike0000 not anymore though Canada the America all get electronic horns or speakers
my area has a lot of systems with bells + we got tons of mircom and im in an area of the united states thats near canada @@nics-systems-electric
My old school had a Edward’s fire bell.

Motor bells are more "fire-alarmy", while solenoid-driven bells sounds like class changing bells in schools. Just my personal view(
Personally I think the 439D series was the best product Edwards ever made. Durable, reliable, and sound really great.
Absolutely do you know what the differences is between the adaptabell vs durabell?

Nic does the fire lite ms-2 have a FACP on it and what? Is it but anyways love your videos can’t wait to see that new room u did in your monthly test
Yes the MS-2 is a fire alarm control panel
Cool. Keep up the good content.
Thanks
Where I am in Canada we have way more simplex bells. Next try the simplex and the 10-24.
It would be no contest Simplex would lose every time whether it’s the old vibrating bells or their new crappy motor bells but maybe I should we’ll see
My school has the 439D series with simplexes and a few G.S. Alarms. I hear them a lot bc people pull fire alarms
Same the doorbell sounds the same as the alarm
NIC'S - forgive my lack of knowledge, but why would you need an end of line resistor? Wouldn't it just be a loop system of positive-negative?
For this demonstration you don’t need an end of line resistor but for a system that is how it monitors the circuit if it doesn’t sense the resistance that means the resistor at the end of the line has been severed from the circuit somehow whether somethings been cut or disconnected it’s a way that the panel can tell if the circuit isn’t intact which could mean devices won’t work
Can you put a Vibrating bell on a motor bell box and vice versa
Good job , keep up the good work
Thanks why did you delete our other conversation?
Because I thought they were weird
It’s the notifier bells the same?
Hey Nic, what year do you think the 439D was released?
I have heard 1984
@@nics-systems-electric okay, do you think Edwards stopped making and discontinued them?
@@kashtonklein4608 Yes they did
@@nics-systems-electric when do you think Edwards made the MB10-24. And do you think Edwards discontinued it too?
@@kashtonklein4608 2001 and they still make it
I don’t understand the crisp clear temporal 3 it sounds fine at my school but it’s notifier not edwards
I guarantee they would sound better if they were vibrating bells motorbells just don’t sound good on code 3
What device did you use to get the temporal 3 output?
MDL sync module
What's the difference between a motor bell and a vibrating bell?
Motor bells uses a motor spinning linkage to the striker vs a vibrating bell uses an electro magnet kind of like a solenoid
my schools have both of those same bells installed
How does a vibrating bell work vs motor bell?
Motor Bell uses a motor that have some sort of gearing and a off centre pin commonly that will move back-and-forth pushing a striker into the gong and a vibrating bell is kind of like a solenoid that moves back-and-forth with electric magnetic fields of a coil
What ones are being manufactured still?
MB 1024
I think the notifier KMS-10-24A is the same
Is there anything better with a notifier bell vs the 10-24
They’re the same thing pretty much
Are bells cheaper?
I think the vibrating bell sounds better in temporal code 3.
Definitely
Cool video
Thanks
why the bright in this video so high
Maybe notifier made a better bell?
Want is your favorite fire alarm brand
For a collector/hobby system Edwards but for a real life system it would be system sensor
Same for me
10-24 and 439D-AWC effects are the same
Nope they are not. Completely different types
So I heard Canada is having wifi problems. You still have wifi
