Step 1:
Insert the bottom edge of the SK-Control-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 standoff attached to the chassis.
Step 3:
Align the long standoff with the short standoff and tighten.

Step 1:
Insert the bottom edge of the SK-Control-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 11/4˝ (31.75mm) standoffs installed
on the rear module.
Step 3:
Align two 4-40 screws with the two standoffs 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.
1.
Install module wiring in accordance with the job drawings and appropri-
ate wiring diagrams.
2.
All wiring to the SK-Control-6 is done via terminal blocks. In order to
properly make electrical connections strip approximately 1/4˝ of insula-
tion 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
To select Class B operation, install the J1 Shunt. 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.
To select Class A operation, remove the J1 Shunt. A maximum of three Class
A circuits are available. For example, if the base address switch is set to 28, 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 opera-
tion, DO NOT set the lowest address above 154, as the other modules will be
assigned to nonexistent addresses.
4.
A shunt is provided to disable a maximum of three unused modules
(see Figure 5). 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, if
the shunt for Address Disable is placed on "two" and the base address
switch is set to 28, the modules will be assigned to 28, 29, 30 and 31,
disabling the highest two positions.
NOTE: In Class A operation, placing the small shunt on "disable 3" will dis-
able all three addresses. Placing the small shunt on "disable 2" will disable
two out of the three addresses. For example, if the address switch is set to
28 and the small shunt is placed on "disable" 2, addresses 30 and 32 will be
disabled while address 28 will be enabled. The SK-Control-6 must have power
cycled for shunt changes to take effect.
5.
There is an active short circuit protection option for each address. The
board is shipped with this option disabled for each address represented
by six large shunts on the "Disable Short Circuit Protection" area. To
SK-460-006
enable short circuit protection for an address, remove the corresponding
shunts on the "Disable Short Protection" area. When enabled, this option
will isolate a short occurring on any active circuit allowing the remaining
circuits to continue normal operation.
NOTE: Short circuit protection may only be enabled if power supply monitor-
ing is enabled.
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.
NOTE: Whether in Class B or Class A wiring, power supply monitoring and
short circuit protection must be enabled on the NAC circuits that are sharing
a power supply.
3
NOTE: Short circuit protection can only be disabled if a power supply is not
being shared by multiple NACs.

NOTE: SLC wiring is the top terminal block, notification appliance/power
supply is the bottom.
wIRING NOTES
•
Power-limited circuits must employ type FPL, FPLR, or FPLP cable as
required by Article 760 of the NEC.
•
For easier wiring, assign all power-limited wiring to one side of the en-
closure rather than alternating with non power-limited.
PROGRAMMING
The modules are programmed as devices in each system according to the pro-
gramming instructions in the appropriate FACP manual.
NAC wIRING AND SUPERVISION
For Class B, Style Y applications (figures 6 and 7 are typical): connect the posi-
tive terminal of the notification appliance(s) to the NAC+ terminal and the
negative device terminal to the adjacent NAC- terminal. Connect one (for each
NAC) of the supplied EOL resistors across the NAC+ and NAC- wires, at the
ends farthest away from the NAC terminal of the SK-Control-6.
For Clas A, Style Z applications (figures 8 and 9 are typical) wire the NACs
per table 2. The A/B select shunt must be removed prior to connecting the SK-
Control-6 to the SLC. The EOL resistors should not be used. The SK-Control-6
is capable of supporting 3 Class A, Style Z NACs. The SK-Control-6 will only
respond at the base address, base address +2, and base address +4 (assum-
ing no addresses have been disabled).
