Re: Color code for home alarm wiring



Now I have another topic that should raise some eyebrows...

Why in all of these years do we use +12V and -12V? In electronics, the
difference is 24Volts!! In Electronics you should use +12V and 0V. But
they use plus and minus on everything!! On panels, on batteries,
everything! Could someone technically explain why -12V is used instead
of 0V's?

Thanks!
