Welcome to ExitSign250! The RU-vid channel all about fire safety and electrical systems. Ever since I was little, I’ve had an interest in fire protection equipment and electricity. And for over 10 years now I have made videos expressing my passion for others to enjoy. I hope you will find my videos to be entertaining, informative, and unique! Thank you for viewing my channel!
Love how the alarm siren is a legitimate mechanical siren used for emergency systems but just shrunken down. Hopefully you got to keep it, they look fun.
When you rebuild your traffic light controller, get the Polara Navigator talking crosswalk buttons, it can be configured if you press or hold the button, it can say to "Wait to cross Main St at Side St"
California used a lot of 8-8-8-12s, except they didn't have an additional red, it was a basic red-yellow-green with an additional large green arrow on the bottom.
Wow what a cool find and great that you are able to keep it. Do you think someone very wealthy and important had that home built? That seems like a lot of money back then and that home is huge! The people restoring it are lucky to have it, I bet it will be so beautiful once done!
Thank you so much! Yes the former owners were very wealthy. It is sad to see such a historical home in great condition be remodeled, but I’m sure it will look great once it’s fully restored.
Interesting. My house still has remnants of an old fire alarm system that was installed in the 1960. In those days residential smoke detectors were uncommon so the system had thermal-detectors throughout thr house. All the bedrooms, thr boiler room, the attic, garage, etc. had thermal detectors . Most of them were set to go off at about 130 deg F but the ones in the attic were set to go off at 190 deg F since during the summer months the attic could get up.to.120-130 deg under normal circumstances.. The system had to be tesred at least once a month to make sure the backup battery was still in good shape and to assure that the system was functional. It used a bell, like the one in you video, as the annunciator should the fire alarm go off. The bell was located in the upstairs hallway near the bedrooms andnit was LOUD!!!.No way anyone would sleep through that. During the late 1970s and early 80s when single station self contained.smoke detectors became popular we installed those throughout the house and gradually the old system was decommissioned. For a while it was only active in the boiler room, laundry room, and attic. A couple years later it was fully decomissioned. Remnants of it still exist. Some.of the bedrooms still have the old heat detectors on the ceiling. Also the boiler room, garage, and attic still have the smoke detectors mounted although none are functional. Most are still connected to an old.panel via the old.alarm wire so at least in theory if I were to supply power to the system at least part of it might still work provided there are no open circuits or shorts . But since I'll be.moving soon I don't have the time to test it.
That’s an extremely cool new signal! My brain thought that the 2 red could be for 2 lanes. Like one red for one lane. Or possibly it could wig wag the reds.
Nice setup once again! I've seen a four-bulb fixture with two reds before in Colorado, however the red heads were side-by-side above the yellow and green heads. Also, how do you control these signals? Are all of the bulbs LED?
Thanks! And that’s pretty interesting. I have a homemade controller that runs the setup. (seen in this video) If you’d like to see the controller in better detail, check out a few of my previous setup videos. And yes, I use LED lightbulbs that emulate incandescent bulbs for my signals.
I'm thinking the reason why there are so many heat detectors and only the one smoke detector is pure economics. When I installed alarms 20 years ago, a heat detector would only cost around $10, smoke detectors would cost 5x more and are more complicated to install. Heat detectors are inexpensive and simple to install. So I could see for this initial installation, the homeowner being sold on one smoke detector, centrally located, with heat detectors throughout the house for some additional protection. Back then too, codes were more relax, only requiring one smoke detector installed outside the sleeping area. So this probably met the code at the time. Today, however, a typical three bedroom, two story (with basement) home would require a minimum of six detectors to be compliant.
@@ExitSign250 I actually miss those left turn signals. There were a lot of them around when I was a kid. It's too bad they didn't think of retrofitting them with LEDs.
Having read some of the comments, im a bit amazed. I've worked on alarm systems older than this building in houses all over london. Admittedly, they are getting rarer and rarer these days, but there are still hundreds of them in every day use, in offices, shops, houses and factories all over the British capital. Some of the old systems ive worked on had normally open detection circuits, and some had normally closed circuits, but some very rare ones had a "flag cell" (essentially a large 1.5v alkali battery) located near to every door contact, usually tucked under the floorboards or in a cupboard, and these were there in order to send a voltage to the control panel, in order to energise a relay, one relay per zone. If the battery died, the cable got cut, or the door was opened, the alarm would trigger. Obviously very similar, yet very different industries in the uk vs north america. I even remember an auto dialler which I had to decommission, which relied on a wax disc record, on which I found a recording made by my predecessor, the installing engineer back in the 60s, saying "police, Scotland Yard, police Scotland yard" and went on to read out the address of the premises and that the burglar alarm had been activated. Totally illegal nowadays to do that, but fascinating to find.
Fascinating video for me. I am a well seasoned (old) security specialist from the UK, who has worked on all sorts of systems since the 90s. During that time, Ive worked on alarm systems which are much older than the house in which you are working, and of course many cutting edge high security systems. Ive always found the history of old such systems fascinating, even down to being able to determine whether the installation engineer was left or right handed based on the direction in which the cores are twisted at the control panel. Thank you for sharing this information. Without someone like you documenting it, it would be lost to time.
