Fire-Lite MS-4 4-Zone Conventional Fire Alarm Control Pane
The Fire•Lite MS-4 and MS-4E Fire Alarm Control Panels (FACPs) bring the latest in microprocessor technology to conventional fire controls. The MS-4 is compatible with the i³™ smoke detectors from System Sensor, with drift compensation, maintenance alert, and freeze warning. Automatic synchronization of audio/visual devices with three selections for manufacturer 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.

| Features | • Four Style B (Class B) Initiating Device Circuits (IDCs). • Two Style Y (Class B) NACs. • Optional module that converts all four IDCs and two NACs to Class A operation. • 24 VDC. • i³™ Technology features: – Drift compensation automatically adjusts detector sensitivity and increases resistance to false alarms caused by dust accumulation. – Maintenance Alert LEDs (per zone) warn of excessive dirt accumulation, preventing false alarms (meets NFPA 72 requirements). – Detector sensitivity is automatically measured by the detector, which automatically adjusts its sensitivity back to the factory settings when it becomes more sensitive due to contaminants settling in the chamber. – Wireless handheld sensitivity meter eliminates the need for voltmeters, magnets, and a physical connection to the detector. The reader displays sensitivity in terms of percent per foot obscuration and provides text status indication. – Supervisory LED (per zone) provides warning if a detector senses temperature approaching freezing. – Special test protocol and LED indication allows quick test of all detectors without need for a ladder. • NAC synchronization features: – Synchronization of standard ANSI audible signals as required by NFPA 72. – Synchronization of ADA compliant strobes per NFPA 72. – Selectable for System Sensor, Wheelock, and Gentex protocols. – Selective Silence feature for manual silence of horns while strobes continue to flash on the same NAC. – Alarm verification selectable for each zone. – Disable switches provided per zone. • NACs programmable for: – Silence Inhibit – Auto Silence – Strobe Synchronization – Selective Silence (horn-strobe mute) – Temporal or Steady signal – Silenceable or Nonsilenceable • Silent or audible Walk Test operation mode commanded from the front keypad, with automatic return-to-normal after one hour of inactivity. • Each zone may be programmed for supervisory or fire; each zone has separate red and yellow LEDs. • Zone 4 is programmable for combination of tamper supervisory monitoring and waterflow alarm. • Form-C Alarm, Trouble, and Supervisory relays. • 3.0 A total usable current. • 6.0 A total usable current available with optional second transformer. • Control buttons: – ACK (Acknowledge) – Alarm Silence – Reset – Walk Test – Zone Enable/Disable (one per zone) • LED indicators: – Fire Alarm (one per zone) – Supervisory (one per zone) – Trouble (one per zone) – Maintenance (one per zone) – AC Power – NAC Disable – Zone Disable – NAC Fault – System Trouble – Power Trouble – Walk Test – Alarm Silence – Earth Fault (on circuit board) – Battery Fault (on circuit board) – Charger Fault (on circuit board) • Piezo sounder for alarm, trouble, supervisory and maintenance. • Optional plug-in 4XTMF transmitter module. • Optional plug-in 4XZMF zone relay module. • Optional 4XLMF transmitter module for RZA-4XF remote LED annunciator. • Optional dress panel. |
