Has anyone here have photos of alarm systems mid replacement or have 2 systems next to eachother usually due to a rewire? Here is what I saw in bucharest airport
Just a note: Siemens has only owned Cerberus Pyrotronics from 1998 onward, so any system from before then is just Cerberus Pyrotronics (though did they sell systems outside North America? Thought they didn’t).
Cerberus was a swiss company owned by “elektrowatt” before being bought by siemens in 1998. pyrotronics is the N.A. division of Cerberus A.G. Cerberus has sold many systems around europe before being bought by siemens.
Right: had a feeling they would have been branded as just “Cerberus” outside North America.
Oh, really? Siemens not only bought out Cerberus Pyrotronics but Cerberus AG as well? Huh…
Sort of: Pyrotronics, Inc. was once a separate US-based life safety manufacturer who were then bought by Cerberus AG of Switzerland in 1988 to create Cerberus Pyrotronics, Inc. (nowdays of course the Pyrotronics name has all but disappeared, though the Cerberus name has not thanks to Siemens using it as part of the model name for their Cerberus PRO-series of FACPs).
Well cerberus pyro is a division of Elektrowatt/Cerberus AG. Elektrowatt was then bought by siemens and cerb pyro was included in the sale
That’s actually pretty common in my country, one notable example I have seen it’s a triple system replacement:
On one side there’s a 1980s Cerberus Guinard (French branch of Cerberus AG, merged with “Société des Pompes Guinard” in 1962), that has been replaced directly (and today I’m sure it controls the smoke vent trapdoors) by an adressable Universal Det/Esser system, I don’t know what the panel is but I know the detectors are IQ8s and it uses Roshni RoLP sounders. Might be a IQ8Control, I couldn’t tell.
Now the older Esser and CG systems are getting both ripped out in favor of a newer Esser system (guessing it’s a ES-Com), identical sounders, as in, the old ROLPs are getting ripped out and replaced with… ROLPs, yes… That’s just… A bit wasteful IMHO, but whatever floats their boat.
I think I have pictures but I’m not really sure if they’re on my phone.. Though given the place this system is in was quite busy, I could only take crappy rushed pictures, so… Don’t expect much if I do end up finding them.
It’s a old mall in Seine-Saint-Denis for the curious ones, I don’t think I am allowed to say exactly which one it is, yet.
I’ve come across upgrades that were in progress on a few occasions. I took photos a few years ago during a system replacement at my university. The building in question had a Simplex 4208 that got replaced with a 4100ES.
I also took this photo a long time ago showing two Edwards 270-series pull stations. The pull station at the bottom is for the new system.
Wow, what a huge leap from one era to another: not even a 4005 or 4010 or otherwise any other Simplex panels in between!
Not sure I get the presence of that 9838 if such horns wouldn’t have been used with the 4208.
I take it that Canada has adjusted its maximum pull station mounting height over the years just as the US has going by that photo (which the latter likely did so that handicapped individuals could activate them if need be). You definitely don’t see one pull station being replaced by another of exactly the same make & model every day though! (probably nearly the exact same design as the older one in this case too!)
Indeed! They kept that 4208 going for a long time. By the time it was replaced, it was perhaps the oldest system on campus.
The horn in that picture is not original to the 4208. Most horns in the building were 4051s, but there were a handful of 9838s that were either replacing 4051s or added later for extra coverage. The one in the photo appears to be replacing a 4051 as the 4051s were mounted on trim plates just like the one behind that horn. The system had a few other random replacement horns (Wheelock MT, EST Integrity, Mircom Select-A-Horn, Simplex 2901-9818).
It’s always neat to come across that type of situation. The same thing happened with the 4208 at my university: the 4251s were replaced with 4099s.
Oh yeah, for sure!
Ah okay, makes sense.
Yeah, though that’s different considering the 4251-series & 4099-series are different model serieses even if the designs are (mostly) identical.
