2. Module Installation
There are two methods for installing a module in the rear position of a chas-
sis. Method one is for installation of a rear module only, when no module will
be installed in front of it. Refer to Figure 3 for instructions. Method two is for
installation of a rear module when another module will be installed in the
chassis position in front of it. Refer to Figures 4a and 4b for method two. All
necessary screws and stand-offs are supplied with the modules.

Step 1:
Insert the bottom of the SK-Zone-6 module down into a rear slot on
the chassis.
Step 2: Carefully swing the upper edge of the board back towards the back of
the chassis until it touches the two stand-offs.
Step 3: Align two 4-40 screws with the two stand-offs and tighten.
Step 4: Address and wire the modules according to the instructions in this
manual.
The steps in Figures 4a and 4b describe and illustrate module installation
when the rear chassis position and the position in front of it will be filled.
Front position installation is possible only if the rear position is filled with a
module.

Step 1: Insert the bottom edge of the SK-Zone-6 module down into a rear slot
of the chassis.
Step 2: Carefully swing the upper edge of the board towards the back of the
chassis until it touches the short stand-off attached to the chassis.
Step 3: Align the long stand-off with the short stand-off and tighten.

Step 1: Insert the bottom edge of the SK-Zone-6 module down into a front
slot of the chassis.
Step 2: Carefully swing the upper edge of the board towards the back of the
chassis until it touches the 1.25˝ (32 mm) stand-offs installed on the
rear module.
Step 3: Align two 4-40 screws with the two stand-offs and tighten.
Step 4: Address and wire the modules according to the instructions in this
manual.
WIRING
NOTE: All wiring must conform to applicable local codes, ordinances, and
regulations.
NOTE: All references to power limited represent "Power Limited (Class 2)".
1. Install module wiring in accordance with the job drawings and appropri-
ate wiring diagrams.
2. All wiring to the SK-Zone-6 is done via terminal blocks. In order to prop-
erly make electrical connections strip approximately 0.25˝ of insulation
from the end of wire, sliding the bare end of the wire under the clamping
plate screw.
3. Set the address on the modules per the job drawing. Use the rotary code
switches to set the address of the first module between 01 and 154.
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 154,
as the other modules will be assigned to nonexistent addresses.
NOTE: The SK-Zone-6 must have power cycled for shunt changes to take effect.
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.
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.
PROGRAMMING
The modules are programmed as devices in each system according to the pro-
gramming instructions in the appropriate FACP manual.
