Q

IDC and NAC circuits monitor for integrity how?

A

They have a slight current with an end of line resistor, when the current doesn’t flow, a trouble is reported. In an IDC circuit, if the resistance is no longer seen because of a short, an alarm is reported.

Q

Why doesn’t the slight current for monitoring a NAC circuit operate the horns/strobes/etc?

A

Because when in alarm, the polarity reverses, and the devices are made to operate only on reverse polarity.
