Something buildings from the 70s that get expanded get horn strobes in the new section and bells with strobes in the old section. I went to a building similar except it had Wheelock alarms
Interesting how they installed the bells and strobes that way. Normally in a case like that, Simplex would've put the bell on a 4905-9921 trim plate with horizontal 4903 strobe, even if they have to get the right-sized backboxes. Or were the strobes installed some time after the bells were?
The strobes came in way after the bells, I just have that feeling by looking at the overall set-up. And I love your idea of the 4905-9921 plate and I would of done the back boxes with them too.
I wonder if this building expanded at some point? I know of a building that opened up in the early 70s and initially had Wheelock bells and when they added an addition in the late 80s early 90sto the building the addition had Wheelock horn strobes and they put strobes in the rest of the building and kept the bells.
I’m not 100% sure, but I think I remember reading somewhere that Simplex panels can sync audible NACs and smartsync horns together. I know that’s what they did at my CTE school which was a mix of TrueAlerts, old Wheelock and AC horns
I wonder if its a Canada thing to put mechanical bells in restrooms? I know the US the days of the bells they weren't in restrooms but modern fire alarms they have sometimes horns or speakers in restrooms and sometimes just strobes
I do find it wierd you guys are allowed to do this. Here, we can only run bells together or horns together, can't really mix them, as you wanna keep the sound consistent. Only time they are 'mixed' is Bells in the halls and Mini Horns in the units. Or the occasional horn swap over and they miss a few bells here and there.
That thumbnail. My local Bed, Bath, & Beyond has some strobes (4904-9137; speaker strobes are 4903-9144’s) hanging loose and even a missing pull station (2099-9795).
Yes, but the horns are smartsync and the bells are not, and smartsync has a different coding pattern than regular coded devices. As mentioned, the panel has the ability to run the circuits so that the audibles turn on and off at the same time.
Malfunction. Over time the mechanisms can wear down to the point where they don't have the power to make the striker hit the gong. One solution is to adjust the mechanism, but that may only last for so long.
@@weatherdan882002 my middle school had to replace 2 1956 gray single stroke bells on the original fire alarms. One in the auditorium with a red bell and one with a scoreboard sounding horn in the art wing due to malfunction. But some point after I went to high school they installed the est genesis speaker strobes in the building. But did leave at least one gray bell mounted after that system was disabled but I don't know if it's still there since they renovated a few years ago
@@FireRescue80 my elementary system fire alarm is just a fail🤦♂️ plastic bag on a fire alarm, simplex 2903 falling, painted over and a nest which wasn’t removed yet.
Basically it's a circuit within a circuit. It's okay on an addressable initiating device circuit because each device is individually addressed and monitored, however for NACs and conventional initiating circuits it's not allowed because the panel can't properly monitor for circuit supervision (if a break we're to happen in the branched off circuit, the panel wouldn't know because it'd still see the end of line resistor in the original circuit).
@@weatherdan882002 there’s a way you can put a EOLR in a device on the same circut, however it is not possible on 2 wire devices I don’t think. On a device that’s 3 wire, you can use the negative terminal your not using and the panel monitors that like it’s an individual device. (Idk if you already knew that)

These fire alarm bells sounds amazing and cool I love the sound of the fire alarm bells when they are on code 3
4:48 We got a Bell in the bathroom!
I remember this place! (I think unless it’s another place with these cool bell combos)

I love a combo between two different alarms.
Yep, A Combo of Newer Horn/Strobes and Older Mechanical Bells.

that's a weird combo. we got Simplex 2901-9333 bells and Truealert horn/strobes, both running on code 3.
Man, this is good, you gotta love simplex!
I didn't watch the whole video, but it's an interesting system.
I like the Simplex 2901-9333. I will likely get it in the future if they're still being sold on Ebay.
Nice! The bells in my school only do continuous.
I think it's cool how we got old bells, oldish horn/strobes and kinda old Trualerts
The horn/strobes are actually ceiling-mount TrueAlerts.
There's also wall-mounted Truealerts as well. The Bells appear to be left over from an older fire alarm system.
I believe the broken bells should be replaced by TrueAlert horns to save money! What alarms are set to replace the broken bells?
Most likely Wheelock bells

Nice video Dan. Hopefully those bells are mended.

It's a money-saving move for sure.
You can't make a building owner remove existing equipment, property rights. Why remove bells?
@@brianthetowerguy979 Who said anything about that?
@@brianthetowerguy979Hes in Canada, they require all fire devices to make the same sound
Update: the light is now fixed and the fire bells too thanks to fire alarm headquarters and fixers
How would you know?
@@ZacharyHappy366 Got a smart brain
@@ToothlessTheCreepydragon9 you sure? Tell me the place then, I was willing to go here but idk what is it
That thumbnail. My local Bed, Bath, & Beyond has some strobes (4904-9137; speaker strobes are 4903-9144’s) hanging loose and even a missing pull station (2099-9795).
Have you heard the system in alarm?
@@GaryBeltz no I haven’t. Panel is probably a 4100.
"which interestingly enough are in sync with the bells"
If the devices are being coded by the facp, its hard for them to get out of sync
Yes, but the horns are smartsync and the bells are not, and smartsync has a different coding pattern than regular coded devices. As mentioned, the panel has the ability to run the circuits so that the audibles turn on and off at the same time.

Are those bells that are vibrating lightly supposed to do that or is that a malfunction?

What's wrong with that second alarm strobe it looks like it's gonna fall
It got hit by something and broke away from the electrical box; needs to be replaced to fix the issue.
@@weatherdan882002 why don’t you add tape?
@@ZacharyHappy366 you can't add tape. The system wouldn't pass inspections if it's taped up.

@@ZacharyHappy366 don't think painting a 2903 is really considered a write up depending on when and how the alarm was painted.
Have they ever fix the strobe in the thumbnail?
Not sure. We replaced the bells though.
@@weatherdan882002 if they replace the bell they shouldn’t left the strobe hanging.
@@rodgodx345 At the time we replaced the bells, the new strobe hadn't come in yet. I'm not sure if it was subsequently replaced or not.
@@weatherdan882002 oh okay.
A LOT of these bells need repairs NOW! Especially the strobe that hung off the junction box with wires.

Some of them don’t need to get replaced cuz it works
