Section 4: Operating Instructions
The SK-2 and SK-4 have two modes of operation which are Normal and Walktest modes. Upon
initial power-up, the system will be in Normal Mode. This section discusses operation of the
control panel in the Normal Mode.
4.1 Switch Functions in Normal Mode
4.1.1 ACK - Acknowledge
The Acknowledge button, which is located on the FACP membrane switch panel, silences the
system piezo sounder and changes all flashing system LEDs to on steady. Pressing the
Acknowledge button will have no effect on the Notification Appliance Circuits. To activate, press
and hold the Acknowledge button for a minimum of one second.
4.1.2 Silence
Pressing the Silence button, which is located on the FACP membrane switch panel, silences the
system piezo sounder, turns off the silenceable Notification Appliance Circuits and turns on the
Alarm Silence LED. The Silence button will be ignored for nonsilenceable waterflows and NACs.
Upon the occurrence of a subsequent event (alarm or trouble), Silence is overridden and the control
panel will respond to the new event. To activate, press the Silence button for a minimum of one
second.
fl
NOTE: If Silence Inhibit has been enabled, NACs cannot be silenced for one minute following
initiation of an alarm.
4.1.3 Zone Enable/Disable
To disable a zone, press the corresponding Zone Enable/Disable button. The Zone Disable and
system Trouble LEDs will blink, as well as the Trouble LED for the disabled zone. To enable the
zone, press the Zone Enable/Disable button a second time.
4.1.4 Reset/(Lamp Test)
The system Reset button, which is located on the FACP membrane switch panel, resets the system
and any smoke detectors. Each press of the Reset button will cause the following:
✓ Clear all status LEDs
✓ Turn off the Notification Appliance Circuits
✓ Reset all zones by temporarily removing power
✓ Silence the onboard piezo sounder
✓ Restore all system relays to normal
✓ Temporarily remove power from the resettable power output
NOTE:
If Silence Inhibit is active, a panel reset cannot occur for one minute.
Any alarm, supervisory or trouble condition that exists after a system reset will resound the system,
reactivating appropriate system activity. Any zones that were disabled before the reset will be
disabled after the reset.
Lamp Test When the Reset button is pressed and then released, the FACP will perform a Lamp
Test. All panel LEDs will be turned on and the piezo will sound for approximately two seconds.

Operating Instructions
4.1.5 Walktest
The Walktest button, which is located on the FACP membrane switch panel, allows a panel
walktest to be performed. Pressing and holding the Walktest button for a minimum of two seconds
causes the FACP to enter audible walktest. Pressing the Walktest button and then the Silence
button and holding both for a minimum of two seconds will cause the panel to enter silent walktest.
Walktest can be exited by pressing and holding the Walktest button for a minimum of three seconds
or by pressing the Reset button. Refer to "Walktest" for a complete description of this feature.
4.2 Walktest
Walktest allows the testing of all control panel IDCs (input zones). An audible or silent walktest
may be performed.
A
WARNING: NO FIRE PROTECTION
IT IS IMPORTANT TO NOTE THAT WHILE THE FACP IS IN WALKTEST MODE, THE CONTROL
PANEL IS IN AN OFF-NORMAL CONDITION AND DOES NOT PROVIDE FIRE PROTECTION.
It should also be noted that the trouble relay will be activated while the control panel is in Walktest
mode. Placing the control panel into Walktest mode will only be possible if the system has no
active alarms.
Prior to initiating a walktest, check to make certain that all system faults have been cleared.
Upon entering Walktest mode, the following conditions should occur:
•
•
•
•
•
•
•
Trouble relay will activate
Alarm relay will be disabled
Supervision relay will be disabled (SK-4 only)
Piezo sounder will be disabled
P smoke detectors will enter their own test mode causing their LEDs to flash twice every five
seconds (refer to the i 3 specification document)
All alarm conditions will be displayed as they occur by blinking zone alarm LED
All zone troubles will be displayed as they occur by blinking zone trouble LED
During walktest, the FACP zone LEDs will blink for the first activation on a zone. Subsequent
activations on the same zone will cause the corresponding zone LED to blink the number of alarms
on the zone since the start of the test, followed by a two second pause and then a repeat of the
sequence.
Note that following a zone activation, a 6 second reset for conventional and 60 second reset for P
detectors is initiated. No new alarms or troubles will be detected during this reset period.
Disabled zones will not respond during Walktest. A zone may be disabled while in Walktest mode,
should a faulty device be detected. This allows the user to return the system to Normal mode,
enabling all other zones while preventing the faulty zone from triggering a false alarm.
Audible Walktest
To perform an audible Walktest, press and hold the Walktest button for a minimum of two seconds.
The Trouble and Walktest LEDs will blink at a 1/4 second rate.
While testing input devices, the first initiating device activated on a zone will cause the NACs to
sound for four seconds. Subsequent device activations on the same zone will cause the NACs to
turn on for one second. Any smoke detectors that are activated will automatically be reset by the
panel. Zone faults (open circuits) will cause the NACs to remain on steadily until the fault is
cleared.

Operating Instructions
Status LEDs
During an audible walktest, if a device remains latched in alarm (such as a Pull Station that is not
reset after activation), subsequent testing of devices on the same zone will no trigger the NACs.
Be certain to reset or clear each device after testing.
Silent Walktest
To perform a silent Walktest, press the Walktest button, then press the Alarm Silence button and
hold both for a minimum of two seconds. The Trouble, Walktest and Alarm Silence LEDs will
blink at a' second rate.
A silent walktest will not activate the control panel Notification Appliance Circuits. All alarm and
trouble conditions must be observed using the LEDs at the control panel as described in the
previous sections.
Exiting Walktest Mode
Walktest mode can be exited by pressing and holding the Walktest button for a minimum of three
seconds or by pressing the Reset button. The time-out feature will cause the control panel to
automatically exit Walktest mode if no button presses have occurred for one hour.

4.4 Operation
Normal mode is the standard mode of operation. In this mode, the panel continuously monitors
system status. When no alarm or trouble conditions exist, the control panel will be in the following
state:
•
•
•
•
•
all LEDs will be off (except the AC Power LED)
the Notification Appliance Circuits will be off
all relays are in their normal state
the onboard piezo sounder will be off
i3 smoke detectors will be polled for maintenance and freeze conditions on initial entry into
Normal mode. Thereafter, each device will be polled every hour for freeze and every four
hours for maintenance conditions
All alarm and system trouble conditions are annunciated on the control panel's LEDs.
NOTE: To ensure that the system is functioning properly, the FACP will perform a freeze check
five minutes after the panel is reset, followed by a maintenance check. If there is no freeze or
maintenance condition, the panel will continue to monitor for freeze conditions every hour and
maintenance conditions every four hours.
