  • Regular price $785.50


The two zone SK-2 is a 24 VDC FACP that provides two Class B

initiating device circuits and one Class B notification appliance circuit (NAC).

The SK-2 NAC protocol includes the ability to silence audible devices while

strobes continue to flash, using only a single pair of wires. The SK-2 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 FACP, activates the FACP alarm relay, and operates an

optional module used to notify a remote station or initiate an auxiliary control function.
