The remote human interface requires 24 VAC + 4 volts
power source and a shielded twisted pair
communication link between the remote panel and the
interprocessor communication bridge (ICPB) module at
the self-contained unit.
Field wiring for both the low voltage power and the
shielded twisted pair must meet the following
requirements:
I I m m p p o o r r t t a a n n t t : : To prevent control malfunctions, do not run
low voltage wiring (30 volts or less) in
conduit with higher voltage circuits.
• All wiring must be in accordance with NEC and
