3.2.1 Output Circuit Programmable Features Description
Command Inputs/NAC Circuit Activation
The SK-PS allows for individual NAC circuit programming. Each NAC can be configured to activate based on the settings selected for up to
3 command inputs.
Set DIP switch positions 1 and 2 according to which input circuit is used as the trigger input for the coordinating configuration as shown
below.
Position 1
Position 2
OFF
OFF
NAC will activate when Input
#1 activates.
ON
OFF
NAC will activate when input
#2 activates.
(Exception: this Input controls
Horn silencing during
Selective Silence operation.)
OFF
ON
NAC will activate when Input
#3 activates (Input #3 is only
available on the SK-PS10
model. If selected on SK-
PS6, this setting will default
to input #2.)
ON
ON
NAC will activate when any
input (1, 2, or 3) activates.
See Section 5 for an explanation of trouble reporting for each mode of operation.
Unused Outputs
The factory default setting for all output circuits is "unused/unsupervised" where positions 3, 4, 5, and 6 are set to the OFF position. Any
unused or disabled outputs in the system configuration must be set to OFF as shown below.
Position 3
OFF
ON
Remote Supply with Resettable and Non-resettable Power
Each output circuit on the SK-PS can be used as a remote stand-alone power supply to provide power to any devices that require filtered,
resettable or non-resettable power. The SK-PS can provide up to 3 amps of continuous current. Non-resettable power is suitable for powering
annunciators and other peripheral equipment. Resettable power is suitable for four-wire smoke detectors. Resettable outputs reset when the
mapped input receives a negative pulse trigger signal from FACP or control module. There will be a three second delay prior to output reset.
The output reset will last 10 seconds. Set DIP switches positions indicated in Table 3.12 below to select auxiliary power type.

Default Normal
N/A
NAC will activate when
Input #2 activates provided
the sync signal is present at
Input #1.
NAC will activate when Input
#3 activates, provided the
sync signal is present at
Input #1 (Input #3 is only
available on the SK-PS10
model. If selected on SK-
PS6, this setting will default
to input #2.)
NAC will activate when input
#2 or input #3 activate
provided sync signal is
present at Input #1.

N/A
NAC will activate when Input
#2 is active regardless of
sync input at Input #1.
If Sync signal is present at
Input #1, the output follows
the sync. If the sync signal at
Input #1 is deemed LOST,
the outputs will turn on
steady.
NAC will activate when Input
#3 is active regardless of
sync input at Input #1.
If Sync signal is present at
Input #1, the output follows
the sync. If the sync signal at
Input #1 is deemed LOST,
the outputs will turn on
steady.
NAC will activate when Input
#2 OR Input #3 is active
regardless of sync input at
Input #1.
If Sync signal is present at
Input #1, the output follows
the sync.
If the sync signal at Input #1
is deemed LOST, the outputs
are turned on steady.
