The ACEND series has now been added to the Siemens website. This page for addressable notification appliances exists, but addressable notification appliances have not been released yet.

Great find! If you expand the subcategories on the left you get the accessories (cover plates, etc.), so the addressable version will look the same on the outside.
Looking through the datasheets, it appears they are unable to do T3/T4 switching that the Wheelock rebrands could do depending on whether the sync signal had the horns silenced or not. Whether this is an oversight or more Wheelock patent bullcrapery, I am unsure. I hope it is just an oversight on the preliminary datasheets, as this feels like a similar situation to the launch of System Sensorās LED L-Series
I think it might be related to Simplexās patents for addressable notification, as there is at least one patent for tone selection via electronic signals, or because the addressable ACEND devices will have this capability. I donāt think Wheelock has filed any patents for their sync protocol since 2008, since the T3/T4 on horns was controlled by the audible silence state. I also suspect that the reason Wheelock has not introduced an Eluxa version of the AMT is because they are waiting to release an addressable version of the ELMT with this functionality over 2 wires.
How could Wheelock make an addressable device if they donāt make the panels?
This also brings up the āissueā with addressable notification becoming the norm in the future. What will brands like Wheelock and Gentex do? They will need to partner up with makers of panels. I think that, for that very reason, Wheelock may actually be taking at least some part in the manufacturing of these new devices.
Eaton does make an addressable power supply that can communicate with SUB-NAC modules, so it is possible that a new version of this power supply will have a larger address range to be able to directly communicate with each notification appliance.
I still find it weird, if they were made to be replacements, why would they drop a feature a previous generation of alarms had? Granted, they were made by Wheelock, but they still used the Siemens sync protocol. I guess weāll see when it releases
I quite like the look of these. The efficiency gains are impressive, too ā especially over the Eluxas!
That page no longer exists. This is the new parent category. Indoor MNS also appears to have been removed from the website.
By āCode 4 Toneā do you mean Temporal 4? Iād love it if they have that feature in an event of CO situations.
More than likely thatās what they mean, though I believe ātemporal 4ā is the official name of that pattern.
Seems very european. The devices seem like they are based of FDS series here in europe. the grille and the plastic texture match the new line and my findings

Siemens has now merged the SL2 chimes/multitones and SET speakers into the ACEND series, and there is a new category for āOutdoor and Special Application Fireā that is empty at this time. There do not seem to be any outdoor LED strobes sold by Siemens at this time.

I find it incredibly odd that they would do that with the multi tone devices when the ACEND horn/strobes will supposedly already be multi tone.
The ACEND horn strobes are 2-wire, but the Eluxa multitone strobes are 4-wire.

At least they are keeping around an option for 4-wire I guess.
Siemens Fire Tech here, lots to say on this topic.
Yes, the XLS is sticking around. We just introduced a new series of detection devices and the XDLC card in the last few years, as well as the ZIC-8B. The XLS (Now Desigo Modular) is far from ending production.
These new ACEND notification devices are yet to be sold or installed by my branch, Iāve never even seen them in person.
As for addressable notification, Siemens has no plans of going that route. We have PAD-5s, which are addressable NAC Extender boards, but the NACs themselves are conventional, only the control board has an address on the SLC card.
Feel free to ask anything else Siemens you might be wondering about, Iām 10 years deep, and my old manās been here for 30. You ask me something I donāt know, Iām sure he will.

We have our first video of one sounding! Iām sure some on here have seen this, but considering the low view count, I donāt think everyone has.
Kinda sounds like a Genesis to me
Interesting that the Code 4 tone sounds like the broadband horn despite being labeled similar to the 500 Hz tone.
