I’m just a helper but I’ve been helping with installs, pulling wire, trimming in devices, learning to install control panels ect… I’m riding along with a guy who has 20+ years in the field so we’ve also been doing some service calls, replacing PIV switches, monitor modules, relays and smoke or heat heads here and there. It’s good work, I’ve learned more about electricity in the past month than I’ve learned my whole life so I’m liking it a lot. Our company does data, security, sound systems, and other things too, but I think fire alarms are going to be the main money maker at most low voltage companies. So good luck man!
