I stumbled across this forum while looking for information on Simplex fire alarms.
Since last December, I've been employed with the most wonderful job of electronics maintenance mechanic for the local school system. Responsibilities include clocks, local sound systems, door bells, burglar alarms, fire alarms, intercoms, and phone systems. I'm absolutely fascinated with 58th minute clocks. Other techs abhor rebuilding them. I find rebuilding them relaxing. Unlike most people on this site, I don't care much for fire alarms, mainly because of the noise. I'll explain.
I've always had sensitive hearing. I've worked in radio, and worn many hats at a recording studio such as tape editor and mastering engineer. I still do remote recording and editing, so my ears don't need to be taking abuse.
I like playing piano, both with my own two hands and with perforated paper rolls. In my teens, I (sort of) played guitar. In the same time period, I played organ at church. At the time, I had no organ of my own on which to practice. A few years ago, the price was right for a three manual, full pedal board digital organ. Unfortunately, I don't have much left over time to play it!
While the other techs at work are very knowledgeable on fire alarms, and they appreciate having a sound guy around, I hope to learn from this forum and to make new friends along the way!
