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

[@GlideoTheGreat]

I love these horns! I hope none get replaced.

[@adamk9652]

Those horns are pissed 😂

[@LiamFire17B-R-qz2xr]

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

[@aidanthetoiletelevatorfire7554]

Awesome System! Love those old mechanical horns!

[@michaelgrahamwongacutemadness]

they’re not that old pretty much like the old 9833 just a digital diaphragm i think

[@aidanthetoiletelevatorfire7554]

@@michaelgrahamwongacutemadness They are from the 1990's, so relatively old, they are very similar to the Simplex 4903-9219/9215/9217, just in a faraday configuration.

[@ticearpey3235]

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.

[@michaelgrahamwongacutemadness]

sometimes they do

[@Yummgator]

I thought the gentex gms was the worst, with the siemens horns coming in close second

[@exoticcar5482]

Funny you mention the 4903 EM horns because those used the same Faraday mechanisms

[@Goldenrod636]

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

[@LgdLegends]

nice pull the fire alarm.💯

[@ZacharyHappy366]

Cool seimens alarm

[@Blueboy197]

Siemens horns running on code 3

[@Blueboy197]

And mini horns too

[@achannelwithnopurpose1977]

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

[@realethanangell]

3:05 Wheelock ZNS or the Edwards mini horn?

[@vintagesimplexfirealarmsof6440]

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

[@achannelwithnopurpose1977]

Says in the description that it’s actually a harrington signal system.

[@GaryBeltz]

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

[@LunaReviews]

The mini horns

[@rickywoodward2053]

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

[@HawkeyeAlarms]

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

[@Loganetics1]

Yes

[@burnoutteamclubbtcp7283]

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

[@Djevan41598]

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

[@shaneyop6486]

Continous with this would be crazy

[@STR2K6]

Harrington panels/systems are really rare these days

[@michaelgrahamwongacutemadness]

Is 2:03 a gentex commander mini horn ceiling mount in white

[@prism_2903]

It looks like a heat detector, at least to me it does

[@JonathanDrouin-rr9qc]

lol they Angy
