Haven’t seen any of those in person but I did see a Remote L-Series horn in walmart. It looks like that remote horn there is from the first generation of when they used xenon.
As far as I know, the remote horn was not changed (since the model is still HRL/HWL/HGRL/HGWL). This means it will not be receiving the T3/T4 functionality that the LED horn strobes will presumably receive.
It just occurred to me that there has been no information on compatibility between the LED L-Series and SWIFT AV bases. Every document I found for the SWIFT AV bases is older than the LED L-Series, and the documentation for the LED L-Series does not seem to mention SWIFT at all. This might be the end of the SWIFT series, since as far as I know, the SWIFT detectors also aren’t listed to UL 268 7th edition.
I believe the SWIFT bases should work for the LED devices since they use the same snap-in bracket from the xenon L-Series. most of the electronics are actually housed in the back box for the SWIFT devices and the actual device just snaps in with the normal horn strobe bracket.
I agree that it would probably work, but it might pose issues when it comes to being officially UL listed. The datasheet specifically says the base works with “compatible” L-Series devices, and it explicitly lists the devices that are compatible, so using any other device would presumably violate the UL listing, even if it should otherwise be expected to work.

On July 23, the LED low frequency sounder strobes received a CSFM listing for “Fire Alarm Devices for the Hearing Impaired”, and on July 25, the new sounders and sounder strobes received a CSFM listing for “Audible Devices.” According to these listings, the sounder strobes will come with 6 selectable tones while the sounders will come with 8 selectable tones, similar to the existing sounders (which have continuous, T3, T4, and coded, all selectable for high/low). This might mean the T3 setting will be changed to T3/T4 while the T4 setting will be kept for retrofits, or it might mean the sounders will be completely redesigned.

A weatherproof device with wire leads where the wire leads sit in the non weatherproof back box. Only the device itself is weatherproof.
Here are some updates with the low frequency sounders:
- The HCWL2-LF is now on ADI Global Distribution. The design is…interesting.
- The HWL2-LF is posted. Unlike the HWL-LF, the HWL2-LF has the grille shaped similar to the strobe models.
- The PC2RLED-LF is also posted, and it looks like they finally have a symmetric design for the ceiling sounders.
- The P2RLED-LF is posted on ADI and Honeywell, and it looks extremely similar to the P2RLED while keeping the larger grille from the P2RL-LF.
Here is the manual. It looks like they significantly improved the power efficiency of these devices, which makes me wonder if they changed the tone as well, perhaps to be more raspy like Wheelock.
I’ve never really had too much of a problem with a device’s looks or had a reason to complain, as it’s how it functions that really matters, but wow… that’s certainly an interesting look. I’m getting the feeling that they just rushed it and took the first design that worked. Between all of these new LED L-Series devices and the Gentex Commander 5 series, it seems like we’re seeing a lot of new devices that were rushed to launch. A new concerning trend possibly?
I wouldn’t be opposed to that idea. Unlike most people, I’m actually a fan of that raspy tone the Wheelock low frequency sounders and the Simplex/Autocall LF sounder bases make. I think it’s a much more attention getting tone that would be even better at waking people up than the already effective regular ones.
One thing I noticed about the new ceiling sounders is that they have a lower sound output compared to the wall sounders. I suspect that this is because the audible portion of the sounder is physically smaller on the ceiling so that the strobe can be in the middle of the device. Updating the sounder-only models likely simplifies production.
The 2025 edition of NFPA 72 has a new section called “restricted audible mode operation” that is similar to private mode except it requires low frequency devices in non-sleeping areas. It is meant to be used in places like preschools where a horn could be problematic, similar to hospitals, and even if a more raspy low frequency sounder will more easily wake people up, it won’t necessarily achieve the intent of this second section low frequency sounders are now required by.
Honeywell’s website now marks many products as discontinued, but the xenon L-Series devices are not consistently marked. For example, on this page, the P2WK is marked as discontinued but the P2WK-P is not, even though they are probably both discontinued. The P2RHK-120 may or may not be discontinued.
Also, the outdoor 4-wire horn strobes now appear to be discontinued.
As far as I know, all of the xenon devices are discontinued. Honeywell has just as bad of websites as they do products.
Do you have a source for this? The LED low frequency devices were only recently released, and there are no 4-wire LED horn strobes or LED ceiling tile devices.
I don’t have complete confirmation, but that’s what I’ve heard. That’s why I said “As far as I know…”. I don’t know if they are doing new 4-wire horn/strobes, but I’m not counting on it.
Good point, and now that I think about it, I don’t recall ever seeing a ceiling tile strobe in a building. I was expecting LED ceiling tiles because the Notifier slides said that in “1H 2024” they would release low frequency devices and “Ceiling Tile (SPS, S, and HS)” which suggests that they were also planning on releasing a horn strobe version. Now that I look back at the slides, there are several other unreleased features: T3/T4 support, the 8-watt speaker, the P2GRKLED-120, and the adapter plate to flush mount outdoor L-Series devices and retrofit them to existing Advance blackboxes. The slides don’t say anything about 4-wire, but they do mention that they will “Eliminate low runner SKU’s and incorporate a bezel strategy” which could mean eliminating 4-wire devices.
There are some LED L Series ceiling-mounted white horn strobes in the newly renovated food court in the mall I go to often.
Possibly good news: although the P4RLED has not been released or even UL listed, searching on this page gives a result. There is no P4WLED that appears from searching, but this might be a sign that 4-wire LED devices will eventually be released.
Considering how long ago the LED L-series was initially released, I wouldn’t be so sure that 4-wire devices are coming, especially with the phase-out of them in general (as much as they’d still be a good idea for non-fire applications if you ask me).
I did at least find this document from 2023 that lists eight 4-wire models, but that seems to be about it.
Low frequency sounders were just released a few months ago, and LED drop-in ceiling tiles have still not been released, so there is still a slight chance…
Didn’t know that was posted. I just saved it to the Wayback Machine in case it gets removed.
Maybe, though I don’t know if System Sensor will repeat that whole “drop-in ceiling tile” thing like they did with the original xenon L-series, which was honestly more bizarre & unorthodox than anything (or that otherwise I doubt anybody would make use of them, especially since the current LED L-series devices should work fine & be compact & unobstrusive enough already).
Good thinking. I found other pages that mention the P4RLED, but that’s the only one I thought to share here.
