Fire Alarm at Retirement Home | Siemens MXL 

Idk why the intro animation is slightly delayed from the audio. Hopefully its not too noticeable

Bro was touching all that Siemen

Compressed air should help with preventing smoke detectors to re alarm.

Those strobes look bright. I'm assuming 75 or 110 candela.

Wait for 10:15 to hear the U-MHUs.

Siemens!! One of my favorite brands. I miss the Faraday Siemens / Cerberus Pyrotronics era of Siemens. Love the MXL systems, just hate how proprietary Siemens is. Makes it hard for collectors and enthusiasts to use them if we ain't techs for them lol.

Oh shit, is that a white UMMT? That's so rare

Gotta love those pull stations which take awhile to reset.

Ah this reminds me of a retirement facility I used to inspect when I was a tech. This place was OLD. It had a Cerberus Pyrotronics PXL in one section of the building and a giant Silent Knight voice evac system in the “tower” section of the building. The building’s history goes back so far and there’s a lot of unused rooms which give it an abandoned building feel. Was always so fun to inspect it and the elevator shafts were awesome. Great video! Well done for documenting while doing the inspection!

That one at the start seemed high pitched, interesting!

Siemens U-MHU-MCS in a retirement facility, I believe it was a very loud system since the U-MHU-MCS can literally blow your ears out.

great video really seeing these tests plus i've been looking for someone testing a Siemens MXL and i finally found one

One comment and a couple questions: 1. I've seen T-handled hex keys (in fact, my dad has a few) which might be easier to reset these pull stations with! Probably would be easier to one-hand, too. 2. 8:37 Are the UMMT and UMHU-series alarms rated for ceiling use? I seem to recall that the SpectrAlert Advance could do that, maybe these can too. I haven't seen any ceiling mount Faraday/Siemens N/As so it may not be far-fetched that they designed the same device to work on both walls and ceilings. 3. Most prominently around 11:15 I hear a sync issue. Are these sections on different NAC's? I'm wondering if the Siemens sync protocol doesn't work between NAC's because I heard this same problem at one of my schools, despite the panel there being an XLS and the two NACs in question being entirely Siemens-rebranded Wheelock equipment (other with mechanical horns were presumably covered under different NACs). You'd hear two areas syncing internally, but one area was sounding at different times than the other.

9:09 Do you bypass ASD when testing? That will make them activate quicker.

Should all fire alarms be at 120db at 80 ft or is that not necessary?

You can make alarm horns in a Function Generator app. I replicated the SpectrAlert Advance, L-Series and the Wheelock NS, ZNS, HSR and horns alike.

What was plugged in below the pull station by the panel when you started the audible test?

My elementary school had these fire alarms

we have those alarms that are school

The pull stations are really inconvenient for maintenance purposes. 😅

how terrible are the mxl panels?

I like Siemens Systems.

Those horn strobes seem unsynchronized.

8:30 Why are there two annunciators?

10:12 who's that guy

Is this a that you? 10:11

why was it doing 4002 t3 at end

Why the hell is the panel date on march if the video was posted on April?
