I can’t believe I’m only just seeing this. The design is very visually appealing and I can’t wait to see these installed in local buildings.
I’m personally not a fan of these XMS pull stations since in my opinion they look weird but I’m glad Siemens is updating there pull stations and using key locks this time. I think the Chevron pull stations are the pull stations that Siemens should be using instead of the MSM-Ks and the MSI-20s
I believe it is also the Chevron, similar to the MS/I series pulls
Not quite - this new one is reset with a key.
I’m talking about the metal model. I’m thinking that it will be the Chevron like the HMS-M was instead of a metal version of the HMS-S.
“All models feature a T-45 reset key to match the fire alarm panel enclosure.”

I wonder if Siemens will keep the Chevrons and the HMS-Ds (anything similar) around after the XMS pull stations came out. I wonder if there going to phase out the older pull stations. If that’s the case, it would be a shame since those chevron style pull stations have been around for a long time (since the 1950s or maybe even earlier).
Interestingly, there appears to be an indentation on the XMS where the GA switch is on the MS-60KS. So, maybe there will be in the future?

Also of note, these pulls seem to activate quite easily

One guess I had after filming this part was that it was because of the braille so blind people wouldn’t need to find the push bar before pulling
I just found this document referring to the XMS-2S, which is purportedly a two-stage pull station. I unfortunately can’t find a datasheet for the XMS-2S or any image of these devices. I’m eager to see what the two-stage models look like.
Same. I wonder if it will use the same switch as the previous Siemens pulls, Simplex pulls, and EST pulls, or if it will use a proprietary switch line in the MS-60KS
That would be pretty damn cool if Siemens made a pre-signal variant of the new Xms pull station
Key features of the XMS series include…
- Key-reset
- Status LED
- Reports a trouble if the cover is opened (I think this is an industry first)
- Built-in fault isolation for class A (redundant) wiring (no separate isolator module needed)

They also make a conventional model too. It’s called the xms-501
The conventional model throws an alarm instead of a trouble when opened. I was expecting it would somehow do something with resistance to throw a maintenance trouble, but nope. Alarm
It looks like the Canadian-market models, including a two-stage version, are finally available. I came across the installation instructions for these models, but I haven’t been able to find a data sheet yet.
Based on the drawings shown in the instructions, it appears that the two-stage version uses a keyswitch similar to that used on the MS-60KS (rather than the more traditional keyswitch used on the MS-53 and its addressable variants).
I find the layout of the bilingual lettering to be rather interesting—I had assumed that the French and English “FIRE” text would be side-by-side, like it is on the MS-series pull stations. It seems that they simply replaced the braille text at the top with French lettering instead of fully redesigning the layout.

If you ask me they should have put it side-by-side, then they could’ve still had the Braille for visually-impaired people while also having bilingual FEU/FIRE lettering for Canada.
Looks like the XMS series has been redesigned.
The new version looks much more well-designed: e.g. the border around the top piece doesn’t cut out on the top, the push flap doesn’t look like it’s haphazardly reused from the HMS series, and the housing uses a consistent font: Siemens Sans, which is the company’s corporate typeface, developed in the 2000’s.

Nice! Still kinda wish the bottom wasn’t lower than the rest for seemingly no reason (along with that weird notch above the lock & the push in part being thickly outlined in white, also for seemingly no reason) but that’s an improvement at least.
