FIRE DETECTION SYSTEM 16600 -5
4. Wiring used for the multiplex communication loop shall be twisted and shielded. The
system shall permit use of IDC and IAC wiring in the same conduit with the
communication loop.
5. All field wiring shall be supervised for open circuits, short circuits, and ground faults.
C. Terminal Boxes, Junction Boxes, and Cabinets: All boxes and cabinets shall be UL Listed
for their use and purpose.
D. The fire alarm control panel shall be connected to a separate dedicated branch circuit,
maximum 20 amperes. This circuit shall be labeled at the main power distribution panel as
FIRE ALARM. Fire alarm control panel primary power wiring shall be 12 AWG. The
control panel cabinet shall be grounded securely to electrical grounding system.
2.03 MAIN FIRE ALARM CONTROL PANEL
A. A listed control panel shall be used. Provide copies from the UL directory indicating
equipment clearly.
B. Signaling Line Circuit (SLC)
1. The SLC Interface shall provide power to and communicate with up to 99 intelligent
detectors (Ionization, Photoelectric, or Thermal) and 99 intelligent modules (monitor or
control) for a system capacity of 198 devices. This shall be accomplished over a single
SLC loop and shall be capable of NFPA 72 Style 4, Style 6, or Style 7 wiring. Provide
loops as required with each loop no more than 80% utilized.
2. The Loop Interface Board (LIB) shall receive analog information from all intelligent
detectors that shall be processed to determine whether normal, alarm, or trouble
conditions exist for each detector. The software shall automatically maintain the
detector's desired sensitivity level by adjusting for the effects of environmental factors,
including the accumulation of dust in each detector. The analog information shall also be
used for automatic detector testing and for the automatic determination of detector
maintenance requirements.
3. The detector software shall meet NFPA 72, Chapter 7 requirements and be certified by
UL as a calibrated sensitivity test instrument.
4. The detector software shall allow manual or automatic sensitivity adjustment.
B. All interfaces and associated equipment are to be protected so that they will not be affected
by voltage surges or line transients consistent with UL Standard 864.
C. Field Programming
1. The system shall be programmable, configurable, and expandable in the field without the
need for special tools or electronic equipment and shall not require field replacement of
electronic integrated circuits.
2. All programming may be accomplished through the standard control panel keypad.
3. All field defined programs shall be stored in non-volatile memory.
4. The programming function shall be enabled with a password that may be defined
specifically for the system when it is installed. Two levels of password protection shall be
provided in addition to a key-lock cabinet. One level is used for status level changes such
as zone disable or manual on/off commands. A second (higher-level) is used for
programming changes.
