Vintage 1962 Simplex Fire Alarm Test, Wiring, and Explanation

This is a complete Simplex Fire Alarm system from around 1962 - it came out of an old school built right around that time. In this video I do a complete install, wire, troubleshoot and test of the system This is my first attempt at a longer video with fancy(ish) production elements; I had to figure out how to do everything as I was doing it...so there may be errors, repeats, audio problems, and way-too-long sections. Please bear with me as I learn how to make grownup videos - I welcome all constructive comments and suggestions. If you'd like to skip straight to the test it's at about 27:58 - but there's a lot you'd miss! Enjoy!
