FIRE-LITE MS-4 Conventional Four Zone Fire Alarm Cont
* 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.
* 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.
* 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.
The 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.
