DF-52266:132•A2-260 MS.4(E) FIM-LITe Alarms Fire Alarm Control Panel by Honeywell Conventional Fire Alarm Control Panels General The Fire-Lite MS-4 and MS-4E Fire Alarm Control Panels (FACPs) bring the latest in microprocessor technology to con- ventional fire controls. The MS-4 is compatible with the 13ro smoke detectors from System Sensor, with drift compensation, maintenance alert, and freeze warning. Automatic synchroniza- tion of audio/visual devices with three selections for manufac- turer protocol.The Notification Appliance Circuit(NAC) protocol can silence audible devices while strobes continue to flash, using a single pair of wires. The MS-4 is 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. Refer to the Fire-Lite Device Compatibility Document for a complete list of compatible devices. Note:Unless indicated otherwise,the term"MS-4"refers to both MS-4 and MS-4E models.
