There's a small medical center near our main hospital that was built in the early 90s with a Simplex 4001 system, with those same horn/lights and single-action pulls, but with 2098-9201 photoelectric smoke detectors instead of the rebranded System Sensor ion detectors. Some time back the 4001 panel was replaced with a Simplex 4006, but everything else was left intact. Our main bus terminal was built in 1999 with a Simplex 4005 system with the same electronic horn/strobes and dual-action pulls, along with a couple of those conventional TrueAlarms and more 2098-9201 detectors.
I really like to see old Simplex systems up after all these years. I get really tiered of the Specter Alert BG-12 combos you see in every building, at least in my area.
@@pvh_facp4001yt Them too, but I've been seeing a lot of Advances used to replace old Simplex alarms, like at my first elementary school and my college where they replaced Simplex 4051+4050-80 horn/lights with Advances on adapter plates...
I've said the same thing about my first elementary school, with a Simplex 4010 (originally a 4004, and before that a 2001 or small 4002) tied into the original Simplex 4208 panel. Though to be fair, the 4208 was used as a slave panel for the existing pull stations and heat sensors.
I was thinking the same thing, they had to run wires between the 4001and 4005 anyway. So for a few extra wires they could of used the 4001 as a makeshift FATC for the 4005 system. Cool system tho.
Here is the problem with do that. The 4001 outputs FWR current while the 4005 outputs dc current. The alarms on the 4001 can operate with FWR, but the alarms on the 4005 do not operate well with FWR, as the strobes may flash faster than it should and the horns will sound like they are dying.
When I was in middle school the Simplex panel went into trouble because of a dirty smoke detector. Why is that? And my elementary school's Spectralert Classics were tied into the school's intercom, so the intercom would make a weird noise
A dirty trouble is triggered when a detector is out of its standard sensitivity value. I.e. it has accumulated dust/particulate and needs to be cleaned.
13:35 what is the model number of that alarm? My elementary school had that alarm along with 4050s in 90bpm march time. I really wanna know the model number
That must be a pain; resetting each panel separately in two different locations when an alarm occurs. I’ve seen this practice of tying panels together when building additions are made but I’ve always wondered why? Is it a cost-saving measure to just install a second panel and wire it with the existing than to just replace the older panel with one that can accept more zones etc?
Not necessarily in every instance. Usually due to the building structure it is sometimes easier and less invasive to just tie the two together. Also customer preference and price plays a role.
i know the police station in cookeville,tn has a simplex system rare 4051s on 4050 lightplates and the performance center might been 4903-9838s replace by spectra alert classics simplex t bars remained panel is a 2001
The Gaylord opryland in Nashville has a combination of simplex alarms like this building but except they have the strobe plate versions of the light plates that are featured in this video. They also have a lot of 2903 light plates, some simplex 4903’s, some simplex truealerts and some Spectralert Advance ceiling mount horn strobes
Simplex used to rebrand numerous companies' smoke detectors, including ESL, Fenwal, Hochiki, Pyrotector, Sentinel, Statitrol, even System Sensor! By the 90s, they eventually settled with Hochiki, to the point where Hochiki's Mexican division now manufactures the stuff Simplex designs and patents themselves!
These detectors tend to last quite a while. My junior high school had them until 2016 (system was installed in 1988), and they were still extremely sensitive. Thankfully, some devices from that system are now in my collection! -ECO
There’s a separate 4 floor medical building in Knoxville with a simplex 4002 all floors had simplex 2903-9001s with 9833s and the office had wheelock MTs and idk how old the building is but it was a neat system
@Vibratone guy of michigan I know I saw one place that had simplex 9838 on 2901 light plates at a huge preschool In flint Michigan I’m from Pontiac Michigan
Here's what this duel system has: Simplex 2901-9838's on Simplex 4903-9001 light plates Simplex 4903-9238's Simplex 4903-9239 Simplex T-Bars Simplex 4001 Simplex 4005 Note: Both panels are on continuous when in full alarm
These don't seem quite as bright. I think these are 9236s. 9238 is 110CD. You would know it was a 9238 if it had an orange triangle, if it isn't a 9238, then it is a speaker version, the 9144, which in this case they aren't. It may be a 9237, which is 30CD, but I don't think so, because that would have a blue circle. If you see a simplex 4903, pay close attention to the candela indicator.
Listen to the Gentex and Space Age and FCI Fire Alarms in Amarillo Texas where I went to Elementary School at Mesa Verde they had Space Age Fire Alarms with the Red Strobes and Travis Middle School and Palo Duro High School had FCI Fire Alarms some of PDHS in Amarillo there a classroom with a Edwards EST Fire Alarms and there was A Wheelock MT Fire Alarm was one of the Fire Alarms in the Main Building of the School and Vocational Building had both Gentex and FCI Alarms and the Day Care one of the Rooms had another Wheelock MT and the new part of the Child Care Wing had Spectra-Alert Classics and the New Wing that they built had also Spectra-Alert Classic But PDHS in Amarillo had almost every different Fire Alarm sound and they were on the Crazy Code the Annoying Code Pulse Code

I actually have one of those rebranded System Sensor detectors. The model is 2098-9110.
Simplex 4903-9238's and Simplex 2901-9838's.
I love those older mechanical horns mixed with the newer 4903 electronic horns, nice! Also were those the only 2 4903-9001's in the building?
Yes I believe so.
4904 is still new but 2 4903 9001s

There’s a church in crossville that has simplex 4903-9219/17s and the daycare side has wheelock 7001ts and the new building added has truealerts
You even snuck an elevator on this video, very cool, hope all is well, and that you and your family are safe.
Great video! It is cool to see an awesome combination of different alarms!
Thanks for viewing!
1:19 LOVE THAT SOUND
This is awesome
Gotta love Simplex! :)
Thanks for the new vid.
nice job cool
looks like the 2901-9838's are running on FWR.
See relly good mate keep up there good work on here mate well done
13:35 what is the model number of that alarm? My elementary school had that alarm along with 4050s in 90bpm march time. I really wanna know the model number
That is a simplex 4903-9239 horn strobe. Same thing as the 9238 but the vertical mount version.

why is it on some of the detectors the alarms only sounded once and not twice like at the beginning???
Depends on what zones were activated.
I've got a question. What does your company use to keep track of inspection reports? The company I work for uses an online program called FormLink
It’s all in house software maintained by corporate.
I like those 9838s
A variety of alarms! I recognize that the simplex 4903's are electronic instead of mechanical.
It was at the time that tyco was fase out on mechanical and go to electromechanical horns
@@WilmingtonOHProductionsThe horns on the 4903 are electronic, not electromechanical.
@@aidanthetoiletelevatorfire7554 I now know that now I didn't know much about this stuff then
I am sad that the 4251-20 is not easy to find on ebay
Is this system set up so the alarms always turn off when the smoke detectors no longer detect smoke, or is it a special test mode?
walk test
The Hard Drive Guru it is a walk test so it will turn off later
Love the video! Keep it up!!
Thanks for viewing!
Did the elevator recall and go into Phase 1??

@safetech what is the model number of the simplex horns in the video
Just wondering what certifications you have to do this?
Various including NICET and local state licensing.
Did you find any deficiencies
My other school used to have that same set up of system but with only one panel with simplex 9838 on 4903 light plates with simplex 4251-20
Plz sucribe my channel if you need learn about fire alarm system
Why is the ceiling so low!?
One of the panels had a Dover beep
It could be found on the 4100 classic to the 4002
They’re also In 4001s and some 4005s and of course the Annunciators.
Are you a firefighter or a principal
I just realized those detectors are Simplex rebranded System Sensor 1700s

You love that audible walktest!
Yea simplex the best
I 😍 ur videos
probably could use new smoke detectors though

Random question. What on earth is a walktest?
This allows each device on the system to be tested solo without the need for a manual reset at the FACP each time a device is tripped.

Good
Wow I'm here before 400 views..
To take it off walk test mod, why not just hit the reset?
Thats not how it works on these panels.
It worked differently on old panels than it does on the new ones
Here's what this duel system has:
Simplex 2901-9838's on Simplex 4903-9001 light plates
Simplex 4903-9238's
Simplex 4903-9239
Simplex T-Bars
Simplex 4001
Simplex 4005
Note: Both panels are on continuous when in full alarm

You would know it was a 9238 if it had an orange triangle, if it isn't a 9238, then it is a speaker version, the 9144, which in this case they aren't.

Aiden, i know. i get confused sometimes. Usually, i would change my comment if someone corrects me.
SAFETECH here's a joke What Earl Pulled the Fire Alarm Get Him
safetech queston how do u get ths job want to wor for alarms the same job you have how do you get ths college and stuff any clues
4:59 2 fire alarms
Yo tengo
How many 9838s did the building have just those 2 only or was there more
Why do you have to reset both panels
It might put the system in alarm instead of walk test.
Jared Thompson oh
@@robscott8296 I take that back. The two panels aren't wired together.

What the guy spraying
Interesting.
lol
It's the walk test
Can you test fire alarm 77
The church look small room
Hi safetech.I am interested in this:What do you spray to smoke detectors after you test them?
The stuff that he sprays is compressed air into the smoke detectors. It forces the fake smoke out of the detectors.
