GENERAL
The Fire•Lite MS-2 and MS-2E Fire Alarm Control Panels
bring the latest in microprocessor technology to conven-
tional fire controls. The MS-2 is compatible with the new
i³™ smoke detectors from System Sensor, and provides
such advanced features as drift compensation, mainte-
nance 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-2 also is compatible with conventional input de-
vices such as two- and four-wire smoke detectors, pull
stations, waterflow devices, tamper switches and other nor-
mally-open contact devices. For 240 VAC operation, order
MS-2E. See the
Fire•Lite Device Compatibility Document
15384 for a complete list of compatible devices.
NOTE: Unless indicated otherwise, the term “MS-2” refers to
both MS-2 and MS-2E models.

• Two Style B (Class B) IDCs (Initiating Device Circuits).
• One Style Y (Class B) NAC (Notification Appliance Circuit).
• 24 VDC.

i³™ Technology features:
— Drift compensation automatically adjusts detector sen-
sitivity and increases resistance to false alarms caused
by dust accumulation.
— Maintenance Alert LEDs (per zone) warn of exces-
sive 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 connec-
tion 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 de-
tector 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 sig-
nals 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.
• 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 and Trouble relays.
• 3.0 amps total usable current.
• Optional dress panel (P/N DP-MS2/4).
