As said above the source of your FA & BA materials probably is the best source for info and TRAINING. Mfg usually like to have qualified techs work on their equipment (no offense intended) MFG training is usually 'cheap' or free.
Mike Holt website has low voltage educational material available.
And, as you're here in NJ, the Board may be able to provide sources also; have your boss (guy with Lic.) call.
I don't know where you're at in "South Jersey"...the County VoTech I teach in has a Burg Alarm nite class; possibly some FA also. It's 13 weeks, 1 nite a week, costs under $150 plus book(s). Union County VoTech, Scotch Plains, NJ. Check with your local County VoTech as they may offer same.
Further info, Jersey style?? Send me an e-mail; it's in my profile.
