CAT5 wired directly to 120V? Inside the box? Yikes! Just goes to show
you that the AG needs to INCREASE the types of systems that fall under
Alarm Service instead of decreasing them. Only someone who hasn't a
clue would wire CAT5 directly to 120V.

But as most alarm people in BC now know, the only thing you need to
prewire alarms is an electrical contractor's licence, knowledge of how
to do it properly is optional. I've seen my share of prewires done by
electricians who use 120V holes for alarm wire and don't see a problem
with that. Same guys who run speaker wires through 120V holes and
terminate the wires at switch level, but no volume control.

How exactly was the LV contractor intending to terminate the CAT5? And
connect to what? If the intention is to use the CAT5 for a LV
transformer, well, it can be done.
