interesting industry…has changed a lot seems like…doing access control as well?What I have done since 1984 is electronic security (burglar alarm systems). My dad started his company in 1971. There was barely a such thing as an actual “control panel when he started in ‘65. Just a bypass keyswitch, magnetic contacts(probably closed loop/NO), a bell and dry cell batteries. Open a door, close the circuit and the bell would ring. Viola, a burglar alarm.
When I came into it, I saw and had to work on the early control panels, with led indicators and “zones”, delay circuits, so you could enter and disarm with 30 seconds, etc. and I also had to do the old stuff, like window foil. Super ‘60’s -‘70’s stuff.
Many times a customer would want something unusual and we’d have to figure a way to make it work with causing false alarms and all while being convenient to use.
I still work with my dad’s long time GM, who was my boss as far back as the late ‘80’s. He is now out of the industry, and is currently the president of a local casino here near SFO. That casino was my father’s company’s client since the late ‘80’s and one of my assigned “job sites”. I know that building inside out. Wired and installed over 100 access control doors virtually alone when they added a huge new part of the building in 1990-91. Now all these years later, it is my client. This is one place where I still have to figure ways to do unique things they want to do.
Such as, two doors with access controls/electric locks, and each door also has a mag lock. When one door opens the other doors mag lock will engage and vice-versa. Simple man trap, but maybe reverse(?).
They have a flood gate in the driveway that will fill with water if it starts to flood, and float up to block any water from getting in the basement garage. I had to make it so when it raises, a light will blink, and it will interrupt the access control system so that no one can run a card by the reader to raise the gate/arm and open the rollup gate into the garage. Oh, and install a test/bypass keyswitch on the whole thing so it can be tested.
A lot of the stuff I used to have to figure out a way to do with PS, timers, and relays can be done with the more sophisticated control panels now, but it still happens that someone wants something weird.
I’m not aware of too many people that stayed in this industry as long as I have, and I’m lucky I was able to go out on my own and be reasonably successful. Not rich, but comfortable, which is fine by me.
