The National Systems Contractors Association (NSCA) Systems
Integration Expo® and the PSA Security Network announced a
strategic partnership today that will result in the creation of
a security and life safety product showcase at the NSCA Systems
Integration Expo® in Las Vegas, March 19-21, 2004. The exhibit
space features PSA manufacturer members but it will not be
exclusive to them.

NICET Fire Alarm Systems Level IV
37003 SYSTEM RELIABILITY
------------------------

37003 is a Level IV General Core work element.

General Work Elements are categorized as either Core or Non-Core
Work Elements. All Level III General Core Work Elements
constitute a mandatory requirement for achieving certification at
Levels III and IV.

37003 DESCRIPTION
Know the methods of installation that will help increase the
reliability and survivability of a system. Understand how to
locate the equipment in a suitable environment, how to provide
physical protection of wiring and components, and how to use
proper wiring methods. Lay out an evacuation system to assure
that attack, by fire, on one paging zone will not cause the loss
of communication on other paging zones. (NFPA 70, NFPA 72)

37003 DESCRIPTION BREAKDOWN:
"Know the methods of installation that will help increase the
reliability and survivability of a system. Understand how to
locate the equipment in a suitable environment, how to provide
physical protection of wiring and components, and how to use
proper wiring methods. Lay out an evacuation system to assure
that attack, by fire, on one paging zone will not cause the loss
of communication on other paging zones."

Glossary of terms

Paging zone. An area covered by voice communication speakers that
are activated simultaneously.

NFPA 72-1999 1-5.5.2.4 Fire alarm system equipment is to be
installed in locations where conditions do not exceed the
following upper and lower limits:
 o 85% and 110% of nameplate voltage
 o Ambient temperatures of 32°F and 120°F
 o At a relative humidity of 85% at an ambient temperature of 86°F

NFPA 72-1999 1-5.8.1 All means of interconnecting equipment,
devices, appliances and wiring connections will be monitored for
integrity such that the occurrence of a single open or a single
ground-fault condition in the installation conductors or other
signaling channels and their restoration to normal will be
automatically indicated within 200 seconds.

NFPA 72-1999 1-5.8.2 Interconnection means will be arranged so
that a single break or single ground fault does not cause an
alarm signal.

NFPA 72-1999 1-5.8.4 An open, ground, or short-circuit fault on
the installation conductors of one alarm notification appliance
circuit will not affect the operation of any other alarm
notification circuit.

NFPA 72-1999 1-5.8.5 The occurrence of a wire-to-wire
short-circuit fault on any alarm notification appliance circuit
will result in a trouble signal at the protected premises.

NFPA 72-1999 1-5.8.6.2 Where a two-way telephone communications
circuit is provided, its installation wires will be monitored for
a short-circuit fault that would cause the telephone
communications circuit to become inoperative.

NFPA 72-1999 2-1.3.4 Connection to the Fire Alarm System.
Duplicate terminals, leads, or connectors that provide for the
connection of installation wiring, will be provided on each
initiating device for the express purpose of connecting into the
fire alarm system to monitor the integrity of the signaling and
power wiring. Except initiating devices connected to a system
that provides the required monitoring.

NFPA 72-1999 3-8.4.1.1.1 Paragraph 3-8.4.1.1 applies only to
systems used for partial evacuation or relocation of occupants.

NFPA 72-1999 3-8.4.1.1.2 A single notification appliance circuit
may not serve more than one notification zone.

NFPA 72-1999 3-8.4.1.1.3* The system shall be designed so that
failure of equipment of a fault on one or more installation
wiring conductors of one notification appliance circuit shall not
result in functional loss of any other notification appliance
circuit.

NFPA 72-1999 3-8.4.1.1.4* Notification appliance circuits and any
other circuits necessary for the operation of the notification
appliance circuit shall be protected from the point at which they
exit the control unit until the point that they enter the
notification zone that they serve using one or more of the
following methods:
(1) A 2-hour rated cable assembly
(2) A 2-hour rated shaft or enclosure
(3) A 2-hour rated stairwell in a building fully sprinklered in
accordance with NFPA 13, Standard for the Installation of
Sprinkler Systems

NFPA 70-1999 760-71 Listing and Marking of PLFA Cables and
Insulated Continuous Line-Type Fire Detectors.
(g) Fire Alarm Circuit Integrity (CI) Cable. Cables suitable for
use in fire alarm systems to ensure survivability of critical
circuits during a specified time under fire conditions will be
listed as circuit integrity (CI) cable. Cables identified in
NFPA 70-1999 760-71(d), (e), and (f) meeting the requirements
for circuit integrity will have the additional classification
using the suffix "CI" (for example, FPLP-CI, FPLR-CI and FPL-CI).

NOTE No. 1: This cable is used for fire alarm circuits as one
method of complying with the survivability requirements of the
National Fire Alarm Code, NFPA 72-1999, 3-8.4.1.1, 3-4.2.2.2,
3-8.4.1.3.3, and 3-8.4.1.3.3.3, that the cable maintain its
electrical function during fire conditions for a defined period
of time.

NOTE No. 2: One method of defining circuit integrity (CI) cable
is by establishing a minimum 2-hour fire resistance rating for
the cable when tested in accordance with the Standard for Tests
of Fire Resistive Cables, UL 2196-1995.

NFPA 72-1999 3-8.4.1.3.3 Fire Command Center Survivability

NFPA 72-1999 3-8.4.1.3.3.3 If the fire command center control
equipment is remote from the central control equipment, the
following requirements apply:	

Interconnecting wiring is to be provided with mechanical
protection by installing the wiring in metal conduit or metal
raceway. Interconnecting wiring will be installed to resist
attack from a fire by routing the wiring through areas whose
characteristics are at least equal to the limited-combustible
characteristics defined in NFPA 90A, Standard for the
Installation of Air Conditioning and Ventilating Systems.

If the interconnecting wiring exceeds 100 feet, additional
resistance to attack from a fire will be provided by either of
the following:
 o Installing the wiring in metal conduit or metal raceway in a
 2-hour fire rated enclosure
 o Enclosing the wiring in a 2-hour fire rated cable assembly
 and installing the cable in metal conduit or metal raceway

Requirements that a fire alarm system voice communication system
be designed and installed such that attack by fire in a paging
zone does not cause the loss of either communication to the
paging zone or communication to the other paging zones relates to
the survivability of the system.

NFPA 72-1999 3-8.4.1.3.4.1 The wiring between the central control
equipment and the primary power supply will be routed through
areas whose characteristics are at least equal to the
limited-combustible characteristics as defined in NFPA 90A,
Standard for the Installation of Air Conditioning and Ventilating
Systems.

NFPA 90A-2002 3.3.19 Limited-Combustible Material. A building
construction material that does not comply with the definition of
noncombustible material, that, in the form in which it is used,
has a potential heat value not exceeding 8141 kJ/kg (3500 Btu/lb)
(see  NFPA 259, Standard Test Method for Potential Heat of
Building Materials), and that complies with either of the
following (a) or (b). Materials subject to increase in
combustibility or flame-spread rating beyond the limits herein
established through the effects of age, moisture, or other
atmospheric condition shall be considered combustible. (a)
Materials having a structural base of noncombustible material,
with a surfacing not exceeding a thickness of 3.2 mm (1/8 in.),
and with a flame-spread rating not greater than 50; (b) Materials
in the form and thickness used, other than as described in (a),
having neither a flame-spread rating greater than 25 nor evidence
of continued progressive combustion and of such composition that
surfaces that would be exposed by cutting through the material on
any plane would have neither a flame-spread rating greater than
25 nor evidence of continued progressive combustion.

NFPA 90A-2002 3.3.20 Noncombustible Material. A material that,
in the form in which it is used and under the conditions
anticipated, will not ignite, burn, support combustion, or
release flammable vapors when subjected to fire or heat.
Materials that are reported as passing ASTM E 136, Standard Test
Method for Behavior of Materials in a Vertical Tube Furnace at
750°C, shall be considered noncombustible materials.
