Reporting Formats Compilation

- This video is a compilation of common reporting formats used by security and fire systems to talk to central station receivers. There is a printer in the background which you do hear several times, which is what that quiet "woof" kind of sound you'll hear throughout the video is.

Dialiar/communicators are a very, very interesting thing to me as an electrical engineer, but there is not a lot of content about them on RUclips. Glad you have made this video!
the legend has uploaded
newageserveralarm used to be a part of my childhood, i used to watch his system test videos when i was little. that was what got me into my hobby of fire alarms. i dont own many, but i will get more soon. i got my first fire alarm in 2012 (a system sensor SpectrAlert Advance SR) and i still have it to this day.
"the legend" is just a random dude from maine who put up a couple fire alarms 10 years ago.
Please. Do not start. Andrew HATES being put on a pedestal, and God forbid Andrew open a RUclips tab... It doesn't mean he's watching fire alarm videos.
Let me just put this out there: it's a dangerous idea to constantly insinuate that anything Andrew does is some indication of him returning to making RUclips videos, and people constantly stalking his Facebook or Twitter is not helping. If he wants to share his endeavors in the security community or any other community, then let him. Don't tie him back to a community he has clearly shown he no longer wants to be a part of.
In my conversations with him, he's made it clear that while he still likes alarms, he doesn't like the direction the community has gone, and especially the way it conducts itself regarding him. He doesn't owe us anything, and we have no right to bug him about it if he doesn't want to. He probably never expected to become a celebrity like figure, and he probably didn't want to be at all. That's probably why he has tried to separate his new hobbies from his old ones, because he wants to be himself again, without little children being on his tail all the time.
And I think that's why he left. When younger and younger kids started using RUclips, Andrew's fanbase turned from a group of mature teens and adults interested in the technology and history of fire alarms to "OMG OMG SpEcTWAAAwERT GOES BeEPpPPP". Thankfully, most of those kids are sticking with Grant from SER Safety and enlisted in the Nine-Year-Old Army. But my point stands.
My point is, It's not about "setting people straight on facts" or even about kids in the hobby, though that's part of it. It's people putting collectors like Andrew or Grant on pedestals. They stop being people and start being celebrities. Objects. There are people in this very comment section who are guilty of this. Countless people still idolize Andrew and they don't want to admit it. They expect him to make more, when he's clearly shown he does not want to.
And the reason I know this is the case is because, for years, I did the same. But I've channeled those feelings into, for instance, admiration for Destin and his music. Not "thesdx." Destin. For Andrew -not "NewAgeServerAlarm", Andrew - it's an appreciation of all he's done, but I've accepted the inconvenient truth that he just doesn't care about us anymore.
Destin is more than just thesdx, he's Destin LeCornu and all that surrounds him. Andrew is more than just NewAgeServerAlarm, he's Andrew Davis and all that surrounds him. Don't idolize them. Treat them like people. It's a shame that many don't realize that Andrew is just as human as the rest of us, and as much as I admire his legacy in this community, he has moved on to a new chapter in his life and we have to let him do what's best for him.
The inconvenient truth is that they have moved on. And regardless of how you feel, that's the way it is.
Thank you for coming to my TED Talk.
I love learning on these formats! Defiantly a part of the fire alarm hobby I usually ignore
Damn contact ID is crazy fast, my panel does SIA20 and I thought that was fast lol
Contact ID sounds fast, but SIA is still technically faster, especially when you consider the fact that it can send highly detailed reports compared to Contact ID, like it can send point names (if the panel supports it, very few do), as well as many other things. It also doesn’t suffer from the problems DTMF has going over voip that Contact ID has.
Great video
This is a very interesting video, CID and SIA are very fast
Cool video
woah, cool! like a dial up modem
Very cool
Is it confirmed that you'll continue the system test series yet? With real fire alarms instead of just the security equipment?
walcome back
Do you live in NYC? Or just New York? I'm curious because I know NYC has a different exit and emergency light code and nobody to my knowledge has made a out'n'about video in NYC
Are you using voip or pots line to transmit between the panel and to the receiver? Also are you using any software automation with the Surgard? Just trying to set up something similar in my training lab for techs.
Is ITI Modem similar to Caddx Modem by chance?
Nope, they're very different.
Are those last few pretty much just Bell 103 modulation?
essentially, just with different methods
Does this have any relation to dial-up? I’ve never seen this before and though that it’s pretty cool, but unfortunately I wasn’t born in the 80s 😂
The three modem formats at the tail end of the video are all using the same technology as dial up internet, just significantly slower
3:26 legit sounds like Hennepin County, MN siren actiavtion FSK
my thoughts exactly
So what model is the receiver
DSC Sur-Gard MLR2 Central Station Receiver
3:01 Why does it show 0's for A's?
it is one of many weird quirks this receiver has
In Contact ID, each digit has a character value: so 1 = 1, 2 = 2, and so on and so forth. However, the designers of Contact ID needed a way for the checksum to add up the digits that are not 1-9. So they modified the typical DTMF character set so Contact ID has 1-9 and A-F where:
0 is represented by A and A = 10
* is represented by B and B = 11
# is represented by C and C = 12
DTMF A is represented by D and D = 13
DTMF B is represented by E and E = 14
DTMF C is represented by F and F = 15
Together with all of this, you can add up the values and get the checksum digit (digit 16 of Contact ID). If the checksum logic makes sense to the receiver, it plays the Acknowledgement tone which signals the panel to either hang up the phone or transmit another message.
So in this case, the message at 3:01 is 2A15181134AAAA1D. The math for the correct checksum adds the first 15 digits: 2 + 10 + 1 + 5 + 1 + 8 + 1 + 1 + 3 + 4 + 10 + 10 + 10 +10 + 1 and this equals 77. You would then subtract 77 from the next greatest multiple of 15, which in this case is 90. 90 - 77 = 13. What digit represents 13 in Contact ID? D!
Hi new age server alarm
