Wow! That is pretty cool they have U-MHTs there rare. Happy to see such notification appliances like that still being used I like those horn strobes...!

Oh I know those. Siemens & Cerberus Pyrotronics has those type of horn strobes. The ones with those blue chips in the horns sound like that.

Very cool! These U-MHTs are not common at all! Interesting choice that they chose continuous.

I think those are actually U-MH-MCS horn/strobes. If I read documentation correctly for them, U-MHTs were designed as temporal-only, while U-MH devices were continuous-only or coded by a NAC.

Kids in school are going to hate that sound for sure as it sounds like Tinnitus. Signals need to be replaced to Siemens rebranded Wheelock LED Eluxa horn strobes doing code-3

I could listen to fire alarms all day and be happy, but dang are those things annoying as heck

Siemens U-MHTs are rare. Surprised to see them installed in a building like this.

Wow, they are loud

Lemme guess, did the current Cerberus pro panel replace an mxl by any chance?

That system sounds like pain lol

Jesus that must be murder for your & everyone else's ears: who's genius idea was it to use U-MHTs instead of normal U-MMTs? (set on what appear to be _continuous_ no less (are they?) At least U-MMTs have somewhat of a gentler sound as an option! Still, nice to see a pre-Wheelock Siemens system still going strong (except for the panel of course). Is that a security keypad I hear beeping around 2:27?

this is kinda interesting for a modern siemens system

Great video! I also have a question, which tone is these alarms set on to?

I don’t remember the horns EVER sounding like that before

What are those set on 1200 hz
