FACP that provides four Class 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-wiresmoke detectors, pull stations,waterflow devices, tamper switches 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.The SK-4/E is compatible with System Sensor®I3detectors providing advanced features such as drift compensation, maintenance alert, and freeze warning.
