New: Siemens Acend notification appliances

Fire Alarm General Discussion
41

Oh yeah: almost kinda like a cross between the Genesis-series & the MT-series in that regard.

Yeah: I noticed that odd inconsistency myself.

42

i were to lower the sound, it would be a genesis

43

Based on this UL listing, it appears that Siemens will be rebranding the outdoor Eluxa devices in the near future instead of releasing outdoor ACEND devices.

44

Sorry to Bump, but someone in that video that they believe they are in a way Manufactured by Eaton/Wheelock exclusively for Siemens. Do you believe this has any validity based on the tones’ similarity?

45

I think this could be possible. It’s also possible that Wheelock/Eaton just gave the tone files to Siemens to use. I know at least for a while the MT tones were available for download online. I actually have an SD card laying around somewhere with the Hi-Lo mp3 on it.

46

I believe that the older simplex true alert multi tones used very similar tones towards the Wheelock MT. I find it odd that there are at least 2 companies using tones that they could probably easily make.

47

I don’t think the tones were directly copied, since the horn tone sounds like a single tone TrueAlert, not an MT. The slow whoops on the TrueAlert and ACEND also cover a wider frequency range.

48

I doubt that eaton has manufactured the device. Based on a previous post I sent they look very similar to a device siemens manufactures in house for the european market

49

I hope another lawsuit doesn’t come in. Some of the tones are still similar to the Mt. Wanna know why I’m saying this? The Eluxa MTs.

50

The multitone TrueAlert was also similar to the MT, but Simplex has not been sued to my knowledge. The Siemens lawsuit was because of the sync protocol, not the U-MMT tones. In fact, the only MT tone that was actually patented was the bell tone, but this patent expired in 2015.

51

It was also because of the remote strobes and speaker strobes (Some of the older ones).

52

Where did you see this? The complaint only lists 3 patents, all of which are about the sync protocol.

53

That’s weird. I thought it was design issues.

54

There has been a lot of speculation online around the cause of this lawsuit, but I haven’t seen any hard evidence of any other cause of the lawsuit. If someone downloads the other documents from PACER and saves them to CourtListener then it could be possible to get more information.

55

was told it was both the sync protocol and ummt/mtl tones

56

Wow…I never knew there was such a thing and I searched it up. Kinda looks a bit bootleg but I still want to chase these when they come out.
