Description
The four zone SK-4/E is a 24 VDC
FACP that provides four Class B
initiating device circuits and two Class
B notification appliance circuit (NAC).
The SK-4/E NAC protocol includes the
ability to silence audible devices while
strobes continue to flash, using only a
single pair of wires. The SK-4/E is also
compatible with conventional input
devices such as two- and four-wire
smoke detectors, pull stations,
waterflow devices, tamper switches and
other normally-open contact devices.
Activation of a compatible smoke
detector or any normally-open fire
alarm initiating device activates audible
and visual signaling devices, illuminates
an indicating LED, sounds the piezo
sounder at the F
ACP, activates the
F
ACP
alarm relay, and operates an
optional module used to notify a remote
station or initiate an auxiliary control
function.
The SK-4/E is compatible with System
Sensor
®
I
3
detectors providing
advanced features such as drift
compensation, maintenance alert, and
freeze warning.
Automatic
synchronization of audio/visual devices
is provided, using three selections for
manufacturer protocol.
Features
• Four Style B (Class B) initiating
device circuits (IDCs)
• Two Style Y (Class B) notification
appliance circuit (NAC)
• Optional module converts all IDCs
and NACs to Class A (PN SK-CAC4)
• Support for synchronization of
standard ANSI audible signals and
ADA compliant strobes per NFPA 72
• Selectable for System Sensor,
Wheelock, and Gentex protocols
• Selective silence feature allows
manual silence of horns while strobes
continue to flash on the same NAC
• Program for combination tamper

SK-4 & SK-4E Fire Alarm
Control Panel
The SK-4 and SK-4E (SK-4/E) are four zone conventional fire alarm
control panels (FACPs) that bring the latest in microprocessor technology
to conventional fire controls. The SK-4 is a 120 VAC FACP and the SK-4E
is a 240 VAC FACP. These FACPs provide reliable fire signaling protection
for small- to medium-sized commercial, industrial, and institutional buildings.
For more information about the SK-4/E system, or to locate your nearest source, please call
1-800-446-6444, or in Minnesota, call 763-493-6435.
4-zone fire protection at a price that won’t
burn your budget.
