Fire Alarm Control Panels

Four Zone Conventional Fire Alarm Control Panel

Four zone conventional fire alarm control panels (FACPs) are compatible with System Sensor® i³™ Series detectors providing advanced features such as drift compensation, maintenance alert, and freeze warning.

Four zone SK-4 are 24V DC fire alarm control panels (FACPs) that provide four Class B initiating device circuits and two Class B notification appliance circuits (NACs). The SK-4 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 2- and 4-wire smoke detectors, pull stations, water-flow devices, tamper switches, and other normally open (NO) contact devices. Activation of a compatible smoke detector or anyNO 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® i³„¢ Series 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.
