Field Work - Elementary School Fire Alarm Test with Simplex Horns on Strobe Plates

The system was fairly recently upgraded from a 4002 to a 4100U, which also added some IDNet devices in a small portion of the building, but the rest is all zoned out unfortunately. There is a couple TrueAlerts in the system, some of the 4903s as well, but mostly horn and light plates. Too many model numbers to list, though there is a System Sensor MASS in the system! Very interesting system!

Ahhh. Those sounds take me back. The nurse at my elementary school said to me when I was like 6 or 7, that the fire alarm drills are only when she picks her nose. And THOSE or THOSE alarms were fucking loud as fuck man. Now these bells and whistles, swear to god thought I would go deaf. Bleeding Christ

[@SomeDudeWithAnExitSign]

If you’re wondering about the alarms here it is Simplex 4903-9215/-9217/-9219 Simplex Truealerts Simplex 2901-9806s on 4903-9101s Simplex 2901-9838s on 4903-9101s Simplex 4901-9805 on a 4903-9101 Simplex 4901-9805 on a 4903-9104 (ceiling mount model) System sensor MASS or MA on a 4903-9101

[@andrewedwards2416]

That mass could just be a ada mass

[@aidanthetoiletelevatorfire7554]

@@andrewedwards2416It may even be a Non-ADA Mass or just a standalone horn. The TrueAlerts have a model number of 4903-9425/9426/9427. The ceiling strobe plate actually looks to me a 4903-9105.

[@Davesand2003]

2:35 this is what all my mechanical horns sounds like

[@FireAlarmDude5967]

2:36 Two problems: Ceiling mount on wall Very scratchy horn (At least it outputs proper candela)

[@michaelglissonjr9490]

Interesting system...... A lot of mix and match alarm devices. Most alarms look to be Simplex Mechanical horn/strobes or lights. Definitely a nice variety.

[@firealarmtechguy4444]

WOW! TrueAlerts and 2901-9838's Together! My favorite and second favorite alarms on 1 system! COOL!

[@catsgame9282]

I think 2901 9846s and 2901 9838s together would be better

[@eb6254]

At my old elementary school there is Simplex 4903s (both 9105 and the one shown at the beginning of the video), Simplex TrueAlert Horn Strobes, and Simplex TrueAlert Speaker Strobes.

[@aidans7376]

At my high school there is 4903 and they are speaker strobes and there is also a true alert speaker strobes and A few system sensor speaker strobes and they installed one set geniuses horn strobe

[@MisterBroadnax]

Did I hear a System Sensor MASS in there?

[@jdrs4214]

Walter G Broadnax III when several of those MASS System Sensor horns set to low-tone continuous go off at the same time, it makes for a scary, loud, fire alarm. In fact, those are the scariest sounding fire alarms I’ve ever heard, when set like that.

[@odinconnor-randomvideos5267]

Yeah

[@evertsstals6861]

Yes in simplex alarm fire is sure old system 2:35

[@andrewchurch452]

Gotta love a good Simplex system.

[@RJARRRPCGP]

I suspected at 3:10 that a System Sensor MA was in a Simplex 4903 or 2903, to replace a dead horn...

[@RJARRRPCGP]

Well, in 1998, maybe 1999 or 1997, IIRC, at Crotched Mountain Rehabilitation Center, (Greenfield, NH and on Wikipedia) next to the gym, one of the '9833s died and a System Sensor MA took its place in the same Simplex 2903-9xxx (probably 2903-9101) strobe plate... (In the Pierce building, which also has the swimming pools)

[@tornadochasingsiege]

My elementary school had a very very weird combination of alarms in it in the front there was one spectralert classic, 2 bg6 pull stations, a gentex SHG 1st gen on continous, 3 wheelock 7002ts and 4 est siga 278 pull stations in the back of the school there was just spectralerts and bg-12L pull stations, and then in the pre school there was spectralerts and est siga 278 pull stations, bg 12 pull stations in the trailers and spectralerts, and ONE gentex commander 3rd generation outside and then on the front of the school there was a weathered, broken spectralert classic that would make only a very quiet clicking sound when activated

[@RaccoonAlarmsVosgra]

2:40 that 2901-9838 sounds like heaven

[@catsgame9282]

That 9838 sounds like a 4903 9219

[@iangilldjsuperdude]

The old and the new fire alarm horns sound like a horror movie when they make echoing noises especially the old Simplex mechanical horn on the 4906 (I think) strobe light plate. Also, I didn’t see the System Sensor Mass. Was the System Sensor Mass a horn/strobe or remote horn? But, don’t take my word for what I am asking. Thank you for serving the fire alarm community by testing the fire alarm systems everywhere! Keep up the good work Fire Alarm Tech!

[@damiengamer15]

aaahhh. Simplex harmony. Exept for the horn at 2:35. It sounded like it's dying out. :(

[@damiengamer15]

No. tell them that they should replace it with another mechanical horn. An electronic one would go horribly with the mechanical horns. Trust me. My school has 9838s and TrueAlerts. Not the best combo.

[@damiengamer15]

... ... ..... I see. It's, really unfortunate that it has to be a TrueAlert or something like that. But, hey. At least things will work again...

[@ZakWolf]

Or since the strobe is still working and is ADA-compliant, they could remove the dying 4901-9805 horn and out in a 4901-9822 electronic horn, which uses the same body as the -9805 but is electronic (it used to use the same sounder as the 90s electronic 4903 horn/strobes, but now uses the same sounder as the TrueAlert.)

[@damiengamer15]

wileyk209zback, agreed. They should.

[@minneeagle]

I think in some parts of my old Kindergarten School in Lake Street, MN, the alarm in the beginning was in some locations, particularly the entrance.

[@whelenvortexr4]

Sounds similar to what my elementary school system is, minus to Tru Alerts. It was installed in the early 90s and is scheduled to be replaced this summer.

[@catsgame9282]

Imagine what would it be like if it was just 2901 9846s and 2901 9838s combo

[@RJARRRPCGP]

Was that a gray Federal Signal Vibratone 450D in the boiler room (I saw those monster pumps, like the Vermont Achievement Center school boilers) at 3:35 ?

[@RJARRRPCGP]

It's probably the usual '9806... (I would only expect it to be gray on that setup, if it's actually a new purchase in this century or sometime in the 1990s...) Federal Signal made them as general-signalling only, in the 2000s and/or sometime in the 1990s...)
