33005 DESCRIPTION BREAKDOWN:
"Know the terms supervision, monitoring integrity, supervisory service,
alarm signal, supervisory signal and trouble signal.

Supervision. The term supervised refers to monitoring of the circuit,
switch, or device in such a manner that a trouble signal is received
when a fault that would prevent normal operation of the system occurs.

Monitoring Integrity. NFPA 72-1999 1-5.8.1 All means of interconnecting
equipment, devices, appliances, and wiring connections will be monitored
for the integrity of the interconnecting conductors or equivalent path
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; with 12 exceptions.

Supervisory Service. The service required to monitor performance of
guard patrols and the operative condition of automatic sprinkler systems
and of other systems for the protection of life and property.

Alarm Signal. A signal indicating an emergency requiring immediate
action, as an alarm for fire from a manual box, a water flow alarm an
alarm from an automatic fire alarm system, or other emergency signal.

Supervisory Signal. A signal indicating the need of action in connection
with the supervision of guards’ tours, sprinkler and other extinguishing
systems or equipment, or with the maintenance features of other
protective system.

Trouble Signal. An audible signal indicating trouble of any nature, such
as a circuit break or ground, occurring in the devices or wiring
associated with a protective signaling system.

"Understand the basic electrical supervision requirements of a fire
alarm system, its purpose, the parts of the system requiring electrical
supervision, those excluded and why, how electrical supervision is
achieved, which supervisory services are available, their purpose, and
the type and location of each of the indicating signals listed above."

NFPA 72-1999 1-5.8.1 All means of interconnecting equipment, devices,
appliances, and wiring connections will be monitored for the integrity
of the interconnecting conductors or equivalent path 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; with 12 exceptions.

NFPA 72-1999 1-5.8.6.1 If speakers are used to produce audible fire
alarm signals, failure of any audio amplifier will result in an audible
trouble signal and failure 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 used, its installation wires will be monitored for a short circuit
fault that would cause the telephone communications circuit to become
inoperative.

NFPA 72-1999 1-5.8.7.1 All primary and secondary power supplies will be
monitored for the presence of voltage at the point of connection to the
system. Failure of either supply will result in a trouble signal in
accordance with NFPA 72-1999 1-5.4.6. The trouble signal also will be
visually and audibly indicated at the protected premises. Where the DACT
is power from a protected premises fire alarm system control unit, power
failure indication will be in accordance with this paragraph, with 4
exceptions.

NEMA 2.17 SUPPLEMENTARY CIRCUITS. Supplementary circuits may include of
the following:
a. Annunciators
b. Signal sounding appliances not required by NFPA 72.
c. Printers
d. Fan shutdown
e. Motor stop
f. Elevator capture

These circuits may be unmonitored, provided the equipment to which they
are connected is not required by NFPA 72, they are designated as
supplementary by the authority having jurisdiction, and a short circuit,
a break, or a ground fault does not prevent the required operation of
the fire alarm system.

End-of-line resistors usually supervise circuits, however, end-of-line
relays, diodes, and capacitors are also used. Supervision of devices and
wiring in some addressable and multiplex systems is accomplished by
polling wherein the control panel polls the devices and wiring then
listens for the expected response.

NFPA 101-97 7-7.2.1 & A7-7.2.1 Where supervised, automatic sprinkler
systems are required by another section of NFPA 101-1997, supervisory
attachments will be installed and monitored for integrity in accordance
with NPFA 72, and a distinctive supervisory signal will be provided to
indicate a condition that would impair the satisfactory operation of the
sprinkler system. This will include, but not be limited to, monitoring
of control valves, fire pump power supplies and running conditions,
water tank levels and temperatures, pressure of tanks, and air pressure
on dry-pipe valves. Supervisory signals will sound and will be displayed
either at a location within the protected building that is constantly
attended by qualified personnel or at an approved, remotely located
receiving facility.

NFPA 72-1999 2-9.1.1 Control Valve Supervisory Signal-Initiating
Devices. Two separate and distinct signals shall be initiated: one
indicating movement of the valve from its normal position and the other
indicating restoration of the valve to its normal position. The
off-normal signal shall be initiated during the first two revolutions of
the hand wheel or during one-fifth of the travel distance of the valve
control apparatus from its normal position. The off-normal signal shall
not be restored at any valve position except normal.

NFPA 72-1999 2-9.2 Pressure Supervisory Signal-Initiating Device. Two
separate and distinct signals shall be initiated: one indicating that
the required pressure has increased or decreased and the other
indicating restoration of the pressure to its normal value. The
following requirements shall apply to pressure supervisory
signal-initiating devices:
(a) A pressure tank supervisory signal-initiating device for a
pressurized limited water supply, such as a pressure tank, shall
indicate both high- and low-pressure conditions. A signal shall be
initiated when the required pressure increases or decreases by 10 psi.
(b) A pressure supervisory signal-initiating device for a dry-pipe
sprinkler system shall indicate both high- and low-pressure conditions.
A signal shall be initiated when the pressure increases or decreases by
10 psi.
(c) A steam pressure supervisory signal-initiating device shall indicate
a low-pressure condition. A signal shall be initiated prior to the
pressure falling below 110 percent of the minimum operating pressure of
the steam-operated equipment supplied.
(d) An initiating device for supervising the pressure of sources other
than those specified in 2-9.2(a) through (c) shall be provided as
required by the authority having jurisdiction.

NFPA 72-1999 2-9.3 Water Level Supervisory Signal-Initiating Device. Two
separate and distinct signals must be initiated: one indicating that the
required water level has been lowered or raised, and the other
indicating restoration.

NFPA 72-1999 2-9.3.1 A pressure tank signal-initiating device must
indicate both high- and low-water level conditions. A signal must be
initiated when the water level falls 3 inches or rises 3 inches.

NFPA 72-1999 2-9.3.2 A supervisory signal-initiating device for other
than pressure tanks must initiate a low-water level signal when the
water level falls 12 inches.

NFPA 72-1999 2-9.4 Water Temperature Supervisory Signal-Initiating
Device. A temperature supervisory device for a water storage container
exposed to freezing conditions must initiate two separate and
distinctive signals. One signal will a decrease in water temperature to
40 degrees F and the other will indicate its restoration to above 40°F.

NFPA 72-1999 2-9.5 Room Temperature Supervisory Signal-Initiating
Device. A room temperature supervisory device must indicate a decrease
in room temperature to 40 degrees F its restoration to above 40 degrees
F.
