Angry Mechanical Horns | Fire Alarm Test #41 

I like these Siemens U-HN-S17 horn strobes a lot. I even like how there are mini horn strobes scattered throughout.

I love these horns! I hope none get replaced.

Those horns are pissed 😂

systems with mechanical horns and mini horns are my favorite. Extremely interesting to me.

1:30 Me when I had that nasty cold in the beginning of the year:

Awesome System! Love those old mechanical horns!

Of all of these late Faraday circuit board mechanical horns, it always seems to be the U-HN and U-HNH that sound the most rough. Simplex’s electromechanical 4903s, the Gentex GMS, and even the D1 series Federal Signal 450 never usually sounded this raspy.

Its good that they sound angry because then that means people will evacuate faster.

Siemens horns running on code 3

Continous with this would be crazy

nice pull the fire alarm.💯

Another rare system i’ve never seen before. Can i get some specs pls?

Was that a mxl system but replaced by silent knight or something

Do you work for a fire alarm inspection company? How do you do these tests?

3:05 Wheelock ZNS or the Edwards mini horn?

Did all classrooms have gentex minihorns or did some have strobes only?

What’s the difference between a horn strobe and a speaker strobe?

Cool seimens alarm

Harrington panels/systems are really rare these days

yeah, the Horns and the Mini-Horn are on code 3

Which devices are the ones that sound like a smoke detector horn instead of the raspy horns?
