- Another test of a location that I was eager to get on film. I tested this place last year, but last year's test was a failure as the upper three floors of this building (7 floors total) had no flashing strobes. Turns out the cause for that was a 4009 (NAC power supply) on the 6th floor that went bad. The week after we were there last year, Simplex came out and fixed the issue (along with various device description changes we recommended). Fast forward to this year and I'm checking things on floors 3, 2, and 1. This year all floors had functional signals, though we did come across a couple of signals that did not function (one of which can be seen at 1:31).
Background info: this building has a networked system consisting of a 4100 in the lobby (which houses the voice evacuation controls) and a 4100ES on the third floor. In addition, there's an 8-story parking garage that adjoins the main building, however that garage has its own system, which is a 4004, with Wheelock AS horn/strobes and Simplex 2099-9138 pulls. The 4004 is set up to trip the main building, however the main building does not trip the 4004. As far as the main building system goes, about 1/2 of the devices are wired to the 4100 and the other half are wired to the 4100ES. On that note, there are 30 smoke/CO combos throughout the building that are wired to the 4100ES, as they are not compatible with the 4100 (they will annunciate on the 4100, though the info displayed is somewhat limited). As far as the signals go, they're a mix of wall and ceiling mount TrueAlerts, plus the one 4903 speaker/strobe seen at the end. When the system activates, it does the brief 500hz tone, then plays the slow whoop tone. There is no voice message that plays and all the floors activate at once. As you can see there are a few areas I couldn't get into, but at least looking through the windows in the doors their signals looked functional. Hopefully next year we'll be able to get into those areas and verify those signals function completely.
P.S., don't mind the radio chatter.

The first beep is what my building has sounded like for years but my childhood was plagued by the main sound in this video lol
3:44 I don’t know why, but I kinda like how the whoop tone sounds when it echoes. It’s pretty cool, but eerie at the same time!
I love your videos
Awesome!
There are some systems that have a combination between Speakers and Horns. therefore, alongside the speakers playing tones and messages, people will also hear the loud screeching from the electronic horns.
Nice. I was expecting the newer whoop. It seems that most of the devices were replaced.
Do you happen to know the name of this sound? I can only find the actual alarm model
@@softis2000 don't know, the name might be in the Simplex software which I don't have.
Hearing the older Slow Whoop over TrueAlert speaker/strobes reminds me of the South Shore Plaza mall in Braintree MA. They had a Simplex 4120 system network installed around 1996, and several of the 4903 speaker/strobes got replaced with TrueAlert speaker/strobes over time. When I heard one of the 4120 systems in action in spring 2010 they did the older Slow Whoop. But they've had an expansion and a few minor renovations since then, so it's likely at least one of the 4120s got upgraded to a 4100ES or something.
Don’t forget to point out that the target at the South Shore Plaza has the system sensor spectralert (ceiling and wall mounted) spsr speaker strobes (and I’m led to believe that they’d do the classic 4100 slow whoop as well since there are also simplex pull stations down there too). It’s sounds very rare to see something like this, and I know that the target probably didn’t exist during the time that you were around their alarm yet, but I heard stories that the newer system sensor spectralert spsr speaker strobes do the same simplex slow whoop just like in the rest of the mall.
And the closest moments I’ve actually been around this exact slow whoop in person, took place at the Needham Sheraton in Needham MA which has a simplex voice evac system but it’s the 4100U and it does the code 3 tone. Then another time was when I was at the south shore plaza as well, but the alarm was already silenced before I got into the mall (and the fire dept was just exiting the mall to return to their trucks when I entering). Lastly: I was traveling out of Boston’s south station and just like the needham Sheraton, they too had a simplex 4100U voice evac in code 3 and the voice evac message was a female one at the train station. It said something like: “when you hear the evacuation tone after this message walk to the nearest exit or exit stairway, do not use the elevators”.
Complete deja vu for me
@@gregorygold4491 I live in Needham MA!
@@gregorygold4491 Oh, I've seen that unusual setup at the Target. I suspect maybe they were going to use a Fire-Lite voice-evac system or something, and had the speaker/strobes and remote strobes already ordered, but ultimately they found it easier to just make it a Simplex system to be on the existing network.
Yep, South Station also has a Simplex 4100U voice-evac system; uniquely it also reuses several components from the Thorn-Kidde voice-evac system it replaced (no doubt they used one of those Thorn/Autocall to 4100U upgrade kits).
@@ZakWolf that’s an interesting fact about south stations fire alarm. When I was around it in June 2018, theres also a funky mix of different speaker strobes there too, simplex truealerts in the cvs and bathrooms (excluding the ones in the metropolitan lounge which are Wheelock speaker strobes/remote strobes, Shockingly there’s also 2 known space age speaker strobes in sync with the system too: one in the ticket room, the other near the exit to the red and silver lines in the basement, and everywhere else, there’s Wheelock e70 speaker strobes and other Wheelock speaker strobes in the food court and the platforms.
3:48 that reverb tho
I didnt hear any bells? But those buildings give me anxiety lol, all the halls look the same, but glad you had fun!
Bell test means to see is fire alarms are functioning or not
Why did it start with a 500 Hz tone?
Interesting it beeped then went into whoop. Wonder why it beeped
Sometimes they're set up for a "pre-alert" tone. I've seen the beep (officially called Horn by Simplex) and the chime tones be used, but I've also seen glitches happen too, so I'm not 100% sure if the tone was supposed to happen or not. If I'm there to test next year, I guess we'll know for sure!
Was the building being purchased by another company or something? All the cubicles looked like they had been emptied. I know you probably try to do the tests when there are no people or very few people in the building but all of the computer and other equipment seems to be gone as well.
Most of the employees still work from home.
0:06 Beep and Slow Whoop
Oh Dear! Dead Speaker/Strobes! That's not good!
9:56 4903!
I'm thinking the devices in this building are:
Simplex TrueAlert Speaker Strobe 4906-9151, 4906-9154, 4906-9101. Maybe 4903-9356, 4903-9196, 4904-9168. The strobes aren't that bright. It is definitely not 75 or 110CD. I think the 4903 is 15CD, so it's probably a 4903-9146 or 4903-9168, but it's not 30 or 110CD.
How come there was no voice message
This is common in high-rise buildings, these buildings are usually fully staffed with a fire safety director who can give instructions over the microphone tailored to what is going on instead of a generic pre-recorded message.
I Was Ask The Same Thing.
IDK, it was just the way it was programmed.
PLEASE PULL THE FIRE ALARM
Agreed. Because seeing him key activating pull stations a lot is kinda getting boring
Do not use the elevators!
Its fine to use eleavtors during a fire alarm inspection.
