GENThe Fire•Lite MS-4 and MS-4E Fire Alarm Control Panels
 bring the latest in microprocessor technology to conventional fire controls. The MS-4 is compatible with the i³™ smoke detectors from System Sensor, and provide such advanced features as drift compensation, maintenance alert, and freeze warning. Automatic synchronization of audio/visual devices is provided, using three selections for manufacturer protocol. The NAC protocol includes the ability to silence audible devices while strobes continue to flash, using only a single pair of wires.

The MS-4 also 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. For 240 VAC operation, order MS-4E. See the Fire•Lite Device Compatibility Document 15384 for a complete list of compatible devices. NOTE: Unless indicated otherwise, the term “MS-4” refers to both MS-4 and MS-4E models.

• Four Style B (Class B) IDCs (Initiating Device Circuits).
• Two Style Y (Class B) NACs (Notification Appliance Circuits).
• Optional module that converts all four IDCs and two NACs
to Class A.
• 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 hand-held 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:
— Provides synchronization of standard ANSI audible signals as required by NFPA 72.
— Provides synchronization of ADA compliant strobes per NFPA 72.
— Selectable for System Sensor, Wheelock and Gentex protocols.
— Selective Silence feature allows manual silence of horns while strobes continue to flash on the same NAC.
• Silent or Audible Walk Test operation mode commanded from the front keypad, with automatic return to normal after one hour of inactivity.
• Programmable for combination tamper supervisory monitor and waterflow alarm on one zone.
• Alarm verification selectable per zone.
• Each zone may be programmed for supervisory or fire, with separate red and yellow LEDs.
• 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
• Form-C Alarm, Trouble and Supervisory relays.
• 3.0 A total usable current.
• 6.0 A total usable current available with optional second transformer.
• Optional dress panel (P/N DP-MS2/4).
