Fire Alarm Control Panel
Section: Conventional
The Fire•Lite MS-4 Fire Alarm Control Panel brings the
latest in microprocessor technology to conventional fire controls. The MS-4 is compatible with the new 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. See the Fire•Lite Device Compatibility Document (Doc. No. 15384) for a complete list of
compatible devices.
• Four Style B (Class B) IDCs (Initiating Device Circuits).
• Two Style Y (Class B) NACs (Notification Appliance Cir-
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, 7-3.2.1).
— 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 contaminents settling in the chamber.
— Wireless handheld sensitivity meter eliminates the
need for voltemeters, 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 (3-
— Provides synchronization of ADA compliant strobes
per NFPA 72 (4-4.4.1).
Optional module that converts all 4 IDCs and 2 NACs to
Class A.
— Selectable for System Sensor, Wheelock and Gentex
— Selective Silence feature allows manual silence of
horns while strobes continue to flash on the same
Silent or Audible Walk Test operation mode commanded
from the front keypad, with automatic return to normal
after 1 hour of inactivity.
Programmable for combination tamper supervisory monitor and waterflow alarm on one zone.
Alarm verification selectable per zone.
Disable switches provided per zone.
Each zone may be programmed for supervisory or fire,
with separate red and yellow LEDs.
NACs programmable for:
— Silence Inhibit
— Auto Silence
— Strobe Synchronization
— Selective Silence (horn-strobe mute)
— Temporal or Steady signal
— Silenceable or Nonsilenceable

Activation of a compatible smoke detector or any normallyopen 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.
