Well made video, great at explaining whats happeing, love the videos and its an amazing view to see how fire alarms are, all I ever knew was a switch and a signal, used to see that command module but had no idea what it was, thanks ro your videos, I learned new things, keep up the good work my guy
My elementary school has Siemens U-MHT-S17 mini horn/strobes in the classrooms and U-HN-S17 mechanical horn/strobes in the hallways, all of which are set on Code 3. However, one of the U-HN’s in the gym was replaced with a Wheelock ZNS. I actually own a U-MHT-S17, three U-MHU-MCS horn/strobes (including Faraday 2834), U-MHST-S17S, U-MHST-S75S, U-MHST-S110S, U-MHST-MCS horn/strobes and a U-MCS-W stand alone strobe.
Nice, my elementary school before it got torn down and rebuild had Simplex 4903-9219s as the main alarm inside the main building and Wheelock MT-24-WMs all around the perimeter, I actually posted a video a while ago of the system being tested.
Then you may have Igniterroremophobia or fear of fire alarms. I may suggest that you watch more fire alarm videos with your volume lowered and progressively turn it up as you get more comfortable, or, purchase some fire alarms starting with strobe onlys, then as you're getting more comfortable, upgrade to a chime/strobe, then a horn or bell/strobe. I used to have that phobia but it went away in 6th grade when I started to develop an interests for fire alarms and fire alarm systems.
this system reminds of a location i recently looked up called Rosemary Square. it had Siemens UMMT's and U-HN's throughout the locations. there was also a couple of Siemens rebranded ZNS's and AS's. they are all over the complex and The UMMT's and the Wheelock alarms were self-coded to code 3 and The U-HN's were coded by the panel to code 3. also, in some portions, they also had a couple of integrities. The Residental apartments also had UMMT mini horns in each unit.
@@BlackLightning4547 and trust me. if i were at Rosemary square, the U-HN's went off, I would get very startled. But i won't get startled by it too much if it was doing code 3.
@Mike Graham yes, the other 3 alarms have two NACs going to them(the alarm in my closet is the EOL). Since the gym only has one NAC, alarms placed in there will have to be in a two-wire configuration
My middle school has a elementary and middle school side. In the elementary side there's Siemens uhnmcs in the hallways mostly and spectralert advances on the stairs. In the middle school side there's wheelock mts and Siemens ummt
Technically speaking, I have no clue. However, people may say that the System Sensor SpectrAlert Advance horn/strobes are the loudest, others may say old school AC mechanical horns, or EST Genesis, or Simplex TrueAlerts, or Wheelock ASs & MTs, it all depends on prospective and the person.
I know this an old vid but I got one of those mechanical horn strobes now! Granted the fire lettering is on the side of the strobe instead of the front of the horn
Cool beans! So you have the S17 or S30 model where the strobe is fixed and not multi-candela? The wall mount MCS versions are the only ones that have the fire lettering on the front while having a multi-candela strobe. The reason being is that the Candela selector is on the side of the strobe, which would've cut into the fire lettering if they had kept the lettering on the sides. Because of that, they put the lettering on the front.
Usually the Siemens U-HN-MCS horn/strobes and other variants have more rasp than the others like the Simplex 4903-9219 and my Gentex WGMS24-75WR even though they use the same mechanism. I was going for a whole Siemens/ Cerberus Pyrotronics themed system
I think it's because FireLite panels tend to use FWR voltage rather than regular DC voltage. Electromechanical horns like the U-HN-MCS don't really like FWR. Think of how the Simplex 4903-9405 and 4903-9217 sound. On my old channel (pivotous), I had a video where I tested a 9217 with my FireLite MS-2, and it sounded awful. Meanwhile when I connected the same alarm to 3 9-volt batteries, it sounds like it's supposed to. FWR and electromechanical horns don't mix.
Hey who told u to bother that alarm I done told u time again these safety equipment are not Toys u could face serious Penalty and fines for messing with safety equipment putting lives in danger don't pull alarm unless it's a fire or emergency
It's MY system that I installed for DEMONSTRATION PURPOSES ONLY( as I said numerous times in my videos) in MY MOM'S HOUSE(where I'm living at the moment). The system doesn't even cover the whole house. The system is local and doesn't dispatched the fire department. Who am I putting in danger? Everyone knows they're not toys and you can face serious penalties. Why do you think I have a disclaimer in my intro as well as in the description to not pull alarms IN PUBLIC BUILDINGS unless there's an emergency?
Knowing the backstory of the Siemens-Wheelock debacle in 2008, the Wheelock sync module's presence further angered the Siemens/Pyrotronics/Faraday horn strobes, as they cannot run on FWR. A short story about how Wheelock screwed Siemens had an impact on these horn strobes. A fellow U-HN-MCS once said: "Get off my turf you stupid Wheelock module, your company has devastated our devices!"
Originally these devices were manufactured by Faraday, who then got bought out from Cueberus Pyrotronics and later Siemens. By the time Siemens had to use Wheelock's devices, these devices were already phased out
