Why did you delete my comment? Did I say something bad? Can anyone take a joke nowadays? I mean i apologize if I offended someone, not really the way to treat your viewers.
the way it's mounted is dampening the vibrating i think...i already adjusted it to make it as loud as i could but i think i may have to adjust the backbox situation
@@BlueThunderboltFireAlarm-um4rp yes, 12v AC. It's a type 1 faraday mechanism. I also have a projectorless type 1 which is 115vAC, I often call it the "port hole" in my videos.
This is so cool! In the early noughties, I worked at ADT as a fire alarm inspector. In a few old homes, I encountered vintage 1910's to 1920's Aero fire alarm systems that were purely mechanical in nature, and required special telegraph lines ran to the building to communicate alarm conditions with the central ADT office of the area. The main unit would be wound up with a clock spring to power the mechanism. In the various rooms, heat detectors - essentially a coil of the copper tubing with heat-exchanging fins - would be mounted to the ceiling and all interconnected with a loop of small copper tubes. The system would be pre-pressurized with a special hand pump. The way the system operated was simple in concept. If a fire broke out and started to heat one of the detectors, the pressure in the closed loop would rise. Once the pressure rose enough, the main control box would be unlocked, and under the power of the clock spring, a mechanical code wheel would begin turning and essentially send out an alarm telegraph message over its dedicated telegraph line. In the ADT office, a telegraph receiver would print out the received telegraph message on a ticker tape. I've only encountered two, maybe three of these systems during my tenure with the company still installed out in the field. One of them was even alleged to still be in service around 2005, but none of the other inspectors or technicians I worked with had the special hand pump required to reset the system, so I never was able to see the system in action. I've only heard stories about these in operation from other well-seasoned inspectors that I worked with, and it was always so intriguing...
I have another video demonstrating the exact wind-up unit you're referring to! I managed to track one of those down a bit later! There's some other components I've learned about that went with this system as well - there were special "rosettes" which would have been used in smaller areas/rooms, that essentially created a larger tripping point for areas that had less space for the tubing - the inspection paper makes mention of these, but I had no idea what it meant at the time of this video! I have since spoken with another tech who also briefly worked on these systems, but there's not a ton of remaining information left about them. I had at one point, found an old advertising video from ADT that had a brief clip of a technician working on one, and it showed one with all the valve keys in it, and the pump attached! Most of this stuff is already lost to time, sadly.
They're space age infinity lamps, now discontinued. The stainless plate & backbox are my choices, though, they did not usually come with anything but the lamp and lens.
@@LXXero Yeah I heard about atlas too but there was a picture online of a fire warden station in WTC 7 and there was a red UK fire alarm looking speaker which idk for sure what it is. Also, I might be getting a TG-4 so I would like to know how do you wire it up to a fire alarm speaker if I want it to do the whoop tone
@@LXXeroyeah I think I got how to wire it now lol. Luckily, I do have an amp circuit which I got for a mini electronic tornado siren I made and it also worked well on my Wheelock E-70
100%, its all just basic components and 4000 ic's. there's been entire analog synths built out of 4000 ic's, infamously, one of my favorites, the wasp!
@@any123-og I've definitely done this & gotten them pretty close, the only thing i'm not 100% sure about is whether they used a separate module entirely for chime vs whoop - this would have meant they might have been set slightly different, even between the two sounds. Given the analog nature of these things, I can't expect perfection.
