PROPOSED NEW NICET REQUIREMENTS IN BOISE, ID
--------------------------------------------

Reprinted from the City of Boise Newsletter "Hammer & Nail" Fall
2002

New Fire Alarm Policy Proposed
To better ensure proper system design and installation and
provide more timely approval of fire alarm permits, the Fire
Dept. and PDS have proposed requiring fire alarm plans to be
developed by qualified persons holding a NICET Level III
Certificate, or a State PE (Electrical or Fire Protection)
Registration License. This conforms with the current edition of
NFPA 72, National Fire Alarm Code, paragraph 1-5.1.3, and related
Appendix material. The system designer (a NICET level III or PE)
would be required to sign the "shop drawings" submitted with the
permit.

Fire Alarm Installer Changes
In addition to being licensed with the City of Boise as Security
Alarm installers and holding the proper State Electrical license,
fire alarm installers would require supervision by a NICET level
II certified person, in accordance with NFPA 72, 1-5.1.4.

Effective Date
It is proposed this new policy become effective January 1, 2003,
to coincide with the adoption of the 2000 IBC & IFC codes, which
include the requirement that "Shop Drawings" be submitted for
fire protection systems (IBC 106.1.1.1; IFC 105.4.3).

Industry Input Requested
We are asking for industry input, to ensure we consider all
pertinent information before a final decision is made. We welcome
your considered comments on this proposal. Please e-mail comments
to Sam Rogers at mailto:srogers@cityofboise.org.

----------------------------------------------------------------

If your State or local municipality require NICET certification,
please let me know so that I can include them in the website
http://www.etnews.org/index.php?s=9&tb=index1.

----------------------------------------------------------------

Have a Happy Thanksgiving everyone!

-------------------------------------------------

34001 is a Level II Special Work element.

34001 DESCRIPTION
Understand an emergency voice/alarm communication system,
including its purpose, operation, basic requirements, power
supply sources, survivability, and types of voice communication
services available. (NFPA 72 and 101)

34001 REFERENCES:
NFPA 72
http://www.nfpa.org/catalog/product.asp?category%5Fname=&pid=7299

NFPA 101
http://www.nfpa.org/catalog/product.asp?category%5Fname=&pid=10100

34001 DESCRIPTION BREAKDOWN:
"Understand an emergency voice/alarm communication system,
including its purpose, ..."
NFPA 72-1999 1-4 Emergency Voice/Alarm Communications. Dedicated
manual or automatic facilities for originating and distributing
voice instructions, as well as alert and evacuation signals
pertaining to a fire emergency, to the occupants of a building.

NFPA 72-1999 3-8.4.1.3 Emergency Voice/Alarm Communications.
Emergency voice/alarm communications service will be provided by
a system with automatic or manual voice capability that is
installed to provide voice instructions to the building occupants
where it is intended that there be only partial or selective
evacuation or directed relocation of building occupants in the
event of a fire. If emergency voice/alarm communications are used
to automatically and simultaneously notify all occupants to
evacuate the protected premises during a fire emergency, manual
or selective paging will not be required, but, if provided, is to
meet the requirements of NFPA 72-1999 Section 3-8.4.1.3

NFPA 72-1999 3-8.4.1.3.1 Application. NFPA 72-1999 3-8.4.1.3
describes the requirements for emergency voice/alarm
communications. The primary purpose is to provide dedicated
manual and automatic facilities for the origination, control, and
transmission of information and instructions pertaining to a fire
alarm emergency to the occupants (including fire department
personnel) of the building. It is the intent of this section to
establish the minimum requirements for emergency voice/alarm
communications.

NFPA 72-1999 3-8.4.1.3.5.1 Voice/Alarm Signaling Service.
General. The purpose of the voice/alarm signaling service is to
provide an automatic response to the receipt of a signal
indicative of a fire emergency. Subsequent manual control
capability of the transmission and audible reproduction of
evacuation tone signals, alert tone signals, and voice directions
on a selective and all-call basis, as determined by the authority
having jurisdiction, is also required from the fire command
center.

Where the fire command center or remote monitoring location is
constantly attended by trained operators, and operator
acknowledgement of receipt of a fire alarm signal is received
within 30 seconds, automatic response is not required.

Where emergency voice/alarm communications are used to notify all
occupants automatically and simultaneously to evacuate the
protected premises during a fire emergency, the ability to give
voice directions on a selective basis will not be required but,
where provided, will meet the requirements of NFPA 72-1999
3-8.4.1.3.


"... operation, ..."
NFPA 72-1999 3-8.4.1.3.5.3.1 Functional Sequence. In response to
an initiating signal indicative of a fire emergency, the system
will automatically transmit the following either immediately or
after a delay acceptable to the authority having jurisdiction:
(a) If the emergency voice/alarm communications service is used
to transmit a voice evacuation message, the voice message will be
preceded and followed by a minimum of two cycles of the audible
emergency evacuation signal specified in NFPA 72-1999 3-8.4.1.2
(Distinctive Evacuation Signal
(b) If the emergency voice/alarm communications service is used
to transmit relocation instructions or other non-evacuation
messages, a continuous alert tone of 3-second to 10-second
duration followed by a message (or messages where multichannel
capability is provided) will be repeated at least three times to
direct the occupants of the alarm signal initiation zone and
other zones in accordance with the building’s fire
evacuation plan.
(c) An evacuation signal is to be transmitted to the alarm signal
initiation zone and other zones in accordance with the building's
fire evacuation plan.

If emergency voice/alarm communications are used to notify all
occupants automatically and simultaneously to evacuate the
protected premises during a fire emergency, and the functional
sequence described in NFPA 72-1999 3-8.4.1.3.5.3.1(a) is
provided, the capability to notify portions of the protected
premises selectively is not required but, if provided, will meet
the requirements of NFPA 72-1999 3-8.4.1.3 (Emergency Voice/Alarm
Communications).

NFPA 72-1999 3-8.4.1.3.5.3.2 Failure of the message described by
NFPA 72-1999 3-8.4.1.3.5.3.1(a), if used, will sound the
evacuation signal automatically. Provisions for manual initiation
of voice instructions or evacuation signal generation is to be
provided.

Other functional sequences are permitted where approved by the
authority having jurisdiction.

If emergency voice/alarm communications are used to notify all
occupants automatically and simultaneously to evacuate the
protected premises during a fire emergency, provision for manual
initiation of voice instructions is not required but, if
provided, will meet the requirements of NFPA 72-1999 3-8.4.1.3
(Emergency Voice/Alarm Communications).


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

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

NFPA 72-1999 1-5.8.6.1 Where speakers are used to produce audible
fire alarm signals, failure of any audio amplifier or of any
tone-generating equipment will result in an audible trouble
signal. Tone-generating and amplifying equipment enclosed as
integral parts and serving only a single, listed loudspeaker will
not be required to be monitored.

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.

NFPA 72-1999 3-8.4.1.3.5.6.2 There are to be at least two
loudspeakers in each paging zone of the building. Each of the
loudspeakers will meet the requirements of NFPA 72-1999 Chapter
4 (Notification Appliances for Fire Alarm Systems).

NFPA 72-1999 3-8.4.1.3.5.6.3 Each elevator car is to be equipped
with a single loudspeaker connected to the paging zone that
serves the elevator group in which the elevator car is located.

NFPA 72-1999 3-8.4.1.3.7.3 Two-way telephone communications
service will be capable of permitting the simultaneous operation
of any five telephone stations in a common talk mode.

NFPA 72-1999 3-8.4.1.3.7.5 A means for silencing the audible
call-in signal-sounding appliance is permitted, provided it is
key-operated, in a locked cabinet, or provided with protection to
prevent use by unauthorized persons. The means will operate a
visible indicator and sound a trouble signal whenever the means
is in the silence position and there are no telephone circuits in
an off-hood condition. If a selective talk telephone system is
used, such a switch is permitted, provided subsequent telephone
circuits going off-hood operate the distinctive off-hook audible
signal-sounding appliance.

NFPA 72-1999 3-8.4.1.3.7.6 Minimum Systems. As a minimum (for
fire service use only), two-way telephone systems are to be
common talk (that is, a conference or party line circuit)
providing at least one telephone station or jack per floor and at
least one telephone station or jack per exit stairway. In
buildings equipped with a fire pump(s), a telephone station or
jack will be provided in each fire pump room.

NFPA 72-1999 3-8.4.1.3.7.7 Fire Warden Use. If the two-way
telephone system is intended to be used by fire wardens in
addition to the fire service, the minimum requirement will be a
selective talk system (where phones are selected from the fire
command center). Systems intended for fire warden use will
provide telephone stations or jacks as required for fire service
use and additional telephone stations or jacks as necessary to
provide at least one telephone station or jack in each voice
paging zone. Telephone circuits will be selectable from the fire
command center either individually or, if approved by the
authority having jurisdiction, by floor or stairwell.


"... power supply sources, ..."
NFPA 72-1999 3-8.4.1.3.4.2 The secondary (standby) power supply
is to be provided in accordance with NFPA 72-1999 1-5.2.5 (Light
and Power Service). Where emergency voice/alarm communications
are used to notify all occupants automatically and simultaneously
to evacuate the protected premises during a fire emergency in
meeting the requirements of NFPA 72-1999 1-5.2.5 (Light and Power
Service), the secondary supply will be required to be capable of
operating the system during a fire or other emergency condition
for a period of 5 minutes rater than 2 hours.

NFPA 72-1999 1-5.2.6 Secondary Supply Capacity and Sources. The
secondary supply will automatically supply the energy to the
system within 30 seconds, and without loss of signals, wherever
the primary supply is incapable of providing the minimum voltage
required for proper operation. The secondary (standby) power
supply will supply energy to the system in the event of total
failure of the primary (main) power supply or when the primary
voltage drops to a level insufficient to maintain functionality
of the control equipment and system components. Under maximum
normal load, the secondary supply will have sufficient capacity
to operate a protected premises, central station, or proprietary
system for 24 hours, or an auxiliary or remote station system for
60 hours; and, at the end of that period, will be capable of
operating all alarm notification appliances used for evacuation
or to direct aid to the location of an emergency for 5 minutes.
The secondary power supply for emergenc!
y voice/alarm communications service will be capable of operating
the system under maximum normal load for 24 hours and then be
capable of operating the system during a fire, or other emergency
condition for a period of 2 hours. Fifteen minutes of evacuation
alarm operation at maximum connected load is considered the
equivalent of 2 hours of emergency operation.


"... survivability, ..."
NFPA 72-1999 3-8.4.1.3.3.2 The fire command center and the
central control unit is to be located within a minimum 1-hour
rated fire resistive area and will have a minimum 3-foot from the
front of the fire command center control equipment except, if
approved by the authority having jurisdiction, the fire command
center control equipment is permitted to be located in a lobby or
other approved space.

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:
(a) The interconnecting wiring is to be provided with mechanical
protection by installing the wiring in metal conduit or metal
raceway.
(b) The interconnecting wiring will be provided with resistance
to 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.
(c) If the interconnecting wiring exceeds 100 feet, additional
resistance to attack from a fire will be provided by either of
the following:
1. Installing the wiring in metal conduit or metal raceway in a
2-hour fire rated enclosure
2. Enclosing the wiring in a 2-hour fire rated cable assembly and
installing the cable in metal conduit or metal raceway

NFPA 72-1999 3-8.4.1.3.6.2 If multiple notification appliance
circuits are provided within an single evacuation signaling zone,
all of the notification appliances within the zone are to be
arranged to activate simultaneously, either automatically or by
actuation of a common, manual control except where the different
notification appliance circuits within an evacuation signaling
zone perform separate functions, for example, presignal and
general alarm signals, predischarge and discharge signals.


"... and types of voice communication services available."
NFPA 72-1999 3-8.4.1.3.5.2 Multichannel Capability. If required
by the authority having jurisdiction, the system will allow the
application of an evacuation signal to one or more zones and, at
the same time, allow voice paging to the other zones selectively
or in any combination.
