- Another bell test that actually involves bells! Ironically, this is in a high-rise apartment building, so you would think this place would have a voice evacuation system, but it does not. From what I can find online, this building was built in 1977, and some of the components do reflect that. As mentioned in the title, the panel is an EST iO500. The system basically monitors the common area/hallway stuff - pull stations (SIGA-270s), smoke detectors (SIGA-PSs) and sprinkler system equipment. Inside each apartment there are three emergency pull cords and a hardwired smoke alarm. Everything in the apartments is hooked up to a separate system whose controls are located in the building's main office. This means the iO500 does NOT monitor the smoke alarms in the apartments, however the pull cord system does and the pull cord system is monitored off-site and emergency services are dispatched any time an apartment pull cord or smoke alarm activates (though there is a 45-second delay before services are dispatched in case anything should be activated accidentally). I mentioned some of the components date back to when the building was built and the prime example is that a good number of the apartments still have Smoke Sentinel smoke alarms installed (with the mechanical horns). Some have been replaced with ESL 320 or 445 series smoke alarms and the more recent replacements include the Gentex 8100 smoke alarm (some with thermal sensors) and Gentex 7139CS smoke alarms with strobes (for the hearing-impaired apartments). Aside from the aged components, the biggest downside is that due to the building wiring, monitoring services aren't able to tell the difference between a fire signal or a medical signal so sometimes the fire department shows up when EMTs should have shown up instead and vice-versa, which can make for a dangerous and frustrating situation. An upgrade would be most beneficial to this building, but I'm sure cost would be a factor (that and although this "system" is messy, it works).
Anyway, back to the test. I check the signals on floors 6-11. The bells go off on all floors and are model 439D-10AW (10", vibrating). There are two exceptions, one of which is seen in the video where one of the bells on the 6th floor is actually a 439D-8AW (8", vibrating). The other exception not seen is the fact that there is an Edwards 881D-AW (vibrating horn) installed in the main lobby of the building as opposed to a bell. I'm not sure why that route was taken, but whatever. Anyway, enjoy the vid!
I've actually seen some high-rise buildings that only partially have voice evacuation... here's one.
**UMass Boston, Healey Library** - 11 floors, 2 basement levels. Simplex system. Most components from 1974 are still largely intact, including 4051+80 horn/lights (some replaced with Wheelock Exceder horn/strobes). The basement (which contains an auditorium) had TrueAlert speaker/strobes installed during the panel upgrade, but old initiating devices (including extremely rare Fire Alert FT-200 ionization detectors) are still intact and the system is still non-addressable. The 11th floor was recently refurbished and has speaker/strobes and addressable initiating devices.
MY GOD, THAT IS COOKIE CUTTER 1970S SUBSIDIZED HUD HIGH RISE CONSTRUCTION WITH THE OFFSET S-SHAPED WITH THE ELEVATORS IN THE CORE AND THE DISTRIBUTED BOILER HEAT AND HOT WATER AND THE CENTRAL EXHAUST / SUPPLY REVERSIBLE AIR DUCTS
THERE WERE SIX OF THESE BUILT ALMOST IDENTICAL ALL OVER THE CAPITAL DISTRICT
Very specific description, lol
@@weatherdan882002 How many floors is this building?
It’s like a Canadian system.
They use the roofs for cellular companies and make a ton of money renting the rooftops to cellular companies
This one has 126 apartments, with 101 being the live in backup emergency contact
100 is the office, mailboxes across from the office and the laundry next to the office and community room at the end with the boilers and trash compactor on the back side of the community room
Each apartment has a pull cord that triggers the on site alarm that transmits a UHF signal and there are on site backup or backup backup people who respond to the office, see which apartment pulled the cord, and respond to the apartment
The pull cord is separate from the fire system you tested
I believe the frequency the radios use is in the 467 MHz range
1/20th of a watt, very low power, so licence is not required and the signal only goes about 100 feet
These buildings were a design that HUD approved in the mid 70s and there are lots of these buildings all over the country
There are 3 boilers that can be linked to run the heat, hot water, in many different configurations, using valves to cross connect, but most of the time they don't know how to do it
They are designed so that if a boiler fails they will not lose heat and hot water
The temperature on the upper floors exceeds 135 degrees 4 months of the year
It is NEVER cold, even if all heat is off, the concrete and the body heat and electricity cause the floors above the first to be at least 70 degrees
But that doesn't stop the people from cranking it up to maximum, because they don't pay for it
These places are HELL
NEVER, EVER LIVE IN ONE, AND NEVER EVER PUT ANYONE IN ONE OF THEM
I KNOW WHAT I AM TALKING ABOUT
I HAVE HORROR STORIES I CAN TELL YOU ABOUT THESE PLACES
Very nice bell test!
Next to apartment 11 along side the elevator shaft is the power room on each floor and across from apartment 1 is the garage shoot
Some mega twoplyboy vibes here :P
Grey 439s? Pretty cool!
I have one of those! Mines 6 inch tho
I have a gray 10 inch 439D. They’re great bells!
Damn I wanted to see the 881D.
Interesting how not only are the bells gray (how is that up to code even?) but how New York seems to have broken off a piece of Canada's fire alarm practices at some point given that you'll sometimes find systems with bells in the state, just like how you'll very often see them in Canada.
Unusual how it seems like a number of NY buildings have the smoke detectors mounted on the walls instead of the ceiling, such as this one & another building you've inspected.
Some of those bells seem too close to something to ring properly, like the one at 0:58.
Odd how the bell at 4:02 sounds different than all the others despite appearing to be the exact same model (is that the 8" bell you mentioned?). Also odd how the building has one bell that's not the same as the others plus the horn.
Isn't it a little redundant to have **3** emergency pull cords inside each apartment? (unless there's one for each room in said apartment)
Odd how supposedly the emergency pull cords & fire alarm initiating devices would be hooked through the same wires, thus meaning the two can't be distinguished. I'm sure with enough work though new wire could be run for the pull cords & probably be programmed as supervisory zones on the iO500.
You know, I just happen to have the 6" version of those bells: 439D-6AW (except red & beat-up). In fact, I think it was the very first notification appliance that I got.
Let fire safety ring!
You ever wonder what happens if a sprinkler is activated in these buildings !????
You ever see an elevator shaft become a raging waterfall ??!!
And the hallway become a river ??!!!
I HAVE !!!!!
this place is disorienting
