In Class B operation, the remaining modules are automatically assigned to the
next five higher addresses. For example, if the base address switch is set to 28,
the next five modules will be addressed to 29, 30, 31, 32 and 33.
The module is shipped in Class B position, remove shunts for Class A. When
operating in Class A, alternate modules are paired together (+0/+1, +2/+3,
+4/+5), resulting in a total of three modules. For example, if the base ad-
dress switch is set to 28, then 30 and 32 will be automatically assigned to the
modules while 29, 31 and 33 are available to be used for other modules on the
SLC. For Class A and B operation, DO NOT set the lowest address above 94, as
the other modules will be assigned to nonexistent addresses.
4. A shunt is provided to disable a maximum of two unused modules in
Class B operation and Class A operation. Modules are disabled from the
highest address and work downward. If two modules are disabled, the
lowest four addresses will be functional, while the highest two will be
disabled. For example, in Class B operation, if the shunt for Address Dis-
able is placed on “two” and the base switch is set to 28, the modules
will be assigned to 28, 29, 30 and 31 while disabling the highest two
positions.

NOTE: Place unused shunts on single pin to store on board for future use.
NOTE: Power must not be applied to the unit when changing functionality of
the shunts.
WIRING NOTES
• Power-limited circuits must employ type FPL, FPLR, or FPLP cable as
required by Article 760 of the NEC.
• All wiring must be in accordance with the NEC, NFPA 72 and all other
applicable codes and standards. All external power supplies must be
power limited with battery back-up. All external power supplies and
detectors must be UL listed for fire protection signaling applications.
1. To select Class A, remove the two shunts from the “A/B select” positions.
2. To use a common power supply between multiple CZ-6 modules, connect a long power supply jumper from T5 or T6 to T5 or T6 on the adjacent CZ-6 module.
