NICET Fire Alarm Systems Level II
33004 BASIC FIRE ALARM SYSTEMS
------------------------------

33004 is a Level II General Core Work element.

All Level II General Core Work Elements constitute a mandatory
requirement for achieving certification at Levels III and IV.

33004 DESCRIPTION:
Know the various types of fire alarm signaling systems. Understand the
operation and differences between noncoded,
zone noncoded, coded, master coded, march time coded, selective coded,
zone coded, voice alarm communication and
evacuation signaling systems. (NFPA 72)

33004 DESCRIPTION BREAKDOWN:
"Know the various types of fire alarm signaling systems."
NFPA 72-1999 1-3.1 This code classifies fire alarm systems as follows:
(1) Household fire warning systems
(2) Protected premises fire alarm systems
(3) Supervising station fire alarm systems
    a. Auxiliary fire alarm systems
       1. Local energy type
       2. Parallel telephone type
       3. Shunt type
    b. Remote supervising station fire alarm systems
    c. Proprietary supervising station systems
    d. Central station fire alarm systems
    e. Municipal fire alarm systems

"Understand the operation and differences between noncoded, zone
noncoded, coded, master coded, march time coded, selective coded, zone
coded, voice alarm communication and evacuation signaling systems."
While the Program Detail Manual-1997 references NFPA 72 only, the NEMA
Training Manual on Fire Alarm Systems is an excellent source of
information for types of 'coded' systems ->

NEMA 2.3 NONCODED SYSTEM. A noncoded system is one in which a continuous
fire alarm signal is transmitted for a predetermined period of time
after which the alarm notification appliances may be manually or
automatically restored to normal.

NEMA 2.4 ZONED NONCODED SYSTEM. A zoned noncoded system provides for the
continuous transmission of the fire alarm signal as in a noncoded
system, but also incorporates an annunciator or display to indicate the
exact area, or zone, of the building from which the alarm originated.

NEMA 2.5 CODED SYSTEM. A coded system is one in which not less than
three rounds of coded fire alarm signals are transmitted after which the
fire alarm system may be manually or automatically restored to normal.
(Also see "selective coded system").

NEMA 2.6 MASTER CODED SYSTEM. A master coded system is one in which the
coding mechanism provides for the transmission of the same common-coded
fire alarm signal in response to the initiation of an alarm from any
location in the building. Common code (e.g. 4-4) should be selected to
produce a distinctive pulsing of the system's alarm notification
appliances so that building occupants know unmistakably that a fire
condition exists.

NEMA 2.7 MARCH TIME CODED SYSTEM. A march time coded system is actually
a noncoded system that operates much like the master coded system except
that the coding mechanism is arranged to produce a fire alarm signal at
a march time rate of approximately 120 pulses per minute.

NEMA 2.8 SELECTIVE CODED SYSTEM. A selective coded system is one in
which a number of code transmitters or remotely mounted devices, or
both, are used; the coding mechanism for each coded unit is
systematically selected and organized to produce its own distinctive
coded alarm signal identifying its location (floor or zone) in the
system. In this way, the sounding of a fire alarm signal notifies the
building occupants of an alarm of fire, and, at the same time, tells key
building personnel, such as an in-house fire brigade, of the location
from which the alarm was initiated. Normally, four rounds of the
selective code are sounded.

NEMA 2.9 ZONED CODED SYSTEM. A zoned coded system also alerts both the
building occupants and key building personnel. While the audible alarms
in a zoned coded system function identically to those in a selective
coded system, zoned coded systems generally are less specific about the
origin of the signal. As its name implies, the signal denotes only the
general area or zone from which one or more different detection devices
may have initiated the alarm.

NFPA 72-1999 A3.8.4.1.2. 1-5.4.7 requires that fire alarm signals be
distinctive in sound from other signals and that this sound not be used
for any other purpose. To meet this requirement, the fire alarm signal
used to notify building occupants of the need to evacuate (leave the
building) will be in accordance with ANSI S3.41, Audible Emergency
Evacuation Signal.

NFPA 72-1999 3-8.4.1.3.5.3.1 In response to an initiating signal
indicative of a fire emergency, the system will automatically transmit,
either immediately or after a delay acceptable to the authority having
jurisdiction, the following:
(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.

(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
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 will 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 a 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 required, will
meet the requirements of NFPA 72-1999 3-8.5.1.3.

NFPA 72-1999 3-8.4.1.3.5.3.3 Live voice instructions will override all
previously initiated signals on that channel and will have priority over
any subsequent automatically initiated signals on that channel. If
multichannel application is required, subsequent alarms will be
activated in accordance with NFPA 72-1999 3-8.4.1.3.5.2.

If 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 live voice instructions is
not required but, if provided, will meet the requirements of NFPA
72-1999 3-8.4.1.3.
