Wiring to be twisted pair of AWG #14 to #20. Route

Zone Interlocking wiring separate from power conductors.

DO NOT GROUND any Zone Interlocking wiring.

The maximum distance between two farthest breakers

on different zones (from the ZO downstream to ZI upstream

terminals) is 250 feet (76m).

A maximum of 20 breakers may be contained in parallel

in one zone.

Provide a self interlocking jumper (on Zone 3) if

coordination is desired with other downstream breakers.

Legend

= Common (ungrounded) --- B7 - Contact

= Zone Out Output Signal --- B9 - Contact

= Zone In Input Signal --- B8 - Contact
from Lower Level Zone
= Fault at Location 2
