My wife is taking a property-insurance course as part of her underwriting certification, and is struggling a bit right now with the alarm portion... specifically, her study guide dives right into full-on "high-low balanced" ULC-spec designs with NO information on the basics of alarm operation... needless to say, not having any background in electronics at all, she's having trouble grasping a lot of this.
Wondering if anyone can point out some online tutorials on basic electronics and alarm operation that might help her out?
TIA.
