Zone Manager Communications
The Zone Manager is the main communication device on the Basic System. It must be
wired correctly and connected to 24VAC power for the system to function. The Zone
Manager must also be addressed correctly. The Zone Manager is normally addressed as
address 0 but should be addressed as 17 if a CommLink is used. Always be sure to
double-check all communication wiring and addressing before initial commissioning of
the system. The address switch must be set and the power cycled in order for the address
to be recognized by the system. Please see Figure 4-2 for the Basic Zone Manager
addressing information.
