Measurements
Fire pump speed shall be measured with an accurate speed indicator. Direct reading digital tachometers
or stroboscopic speed indicators can be used to record fire pump speed.
If a contact-type speed indicator is used, a plug or cap is removed from the end of the fire pump casing
so that the speed indicator can contact the end of the fire pump shaft. Any oil or grease on the end of the
shaft shall be removed before the speed device is inserted. When using a revolution-counter (for fire
pumps 2,500 RPM and over) take a reading for two minutes and divide by two to determine the oneminute measurement. This minimizes starting and stopping timing errors.
Calibrated pressure gauges shall be used during the test and shall be checked against the gauges that are
installed on the fire pump.
Test headers are provided for fire pump tests. A separate 2½-inch outlet is required for every 250 GPM
rating of the fire pump. Lengths of 2½-inch hose with straight bore nozzles (Underwriters’ Play Pipes)
are attached and firmly supported. It may be feasible to attach the straight bore nozzle directly to each
outlet of the test header if water damage can be prevented. Water is flowed through nozzles and
measured by use of a Pitot gauge.
Pitot pressure, size of outlet, outlet coefficient, fire pump intake pressure, fire pump outlet pressure and
fire pump speed shall be tested and recorded. These tests are repeated and recorded for each of the
flows. Results of the tests are plotted on a special graph commonly known as N 1.85 paper and compared
with the manufacturer’s fire pump test curve and the requirements of NFPA No. 20, “Standard for the
Installation of Centrifugal Fire Pumps.”
5.6.3
Annual Flow Test Procedures
Flow tests shall be conducted from the fire pump test header with the discharge valve to the site
underground fire main piping being closed. This arrangement will prevent unwanted conditions such as
blowing-out of pipe in the site underground fire main. Impairment procedures shall be followed in
accordance with insurance company policy.
It is critical that the alignment of the flexible coupling between the fire pump and the driver be checked
annually.
Discharge and suction pressure for a horizontal fire pump shall be read at gauges located at the
centerline of the fire pump on the casing.
Vertical turbine fire pump discharge pressure is recorded from a gauge located at the discharge head
fitting.
5.6.4
Power Supply
5.6.4.1 Over-current Protection
Standard 104
14
5.6.4.1.1 Fire Pump Controller
The circuit breaker shall be inspected to verify that the breaker meets the following specifications:
-
The continuous current rating shall be at least 115 percent of the fire pump motor’s rated fullload current as shown on the nameplate of the over-current device.
The interrupting capacity shall be equal to or greater than the maximum fault-current possible at
the location of the breaker, as determined by the manufacturer.
The instantaneous trip setting shall be at least 12 times the full-load current rating of the fire
pump motor.
This setting is shown on the nameplate of the over-current device. An instantaneous trip setting as high
as this is necessary because of the “spike” or current surge when the motor attempts to start at the peak
of the current cycle.
-
The overload trip mechanism shall be set at 300 percent of the motor full-load current. At
locked-rotor current (about 600 percent of the motor full-load current), the circuit breaker must
trip in 8 to 20 seconds. This setting is shown on the nameplate of the over-current device.
Direct current motors shall have circuit breakers that will trip instantaneously at or above 400 percent of
the motor full-load current. This protects the motor insulation against heat generated in an extended
lock-rotor condition.
5.6.4.1.2 Fire Pump Feeder Circuit
Fuses, if used, shall have:
-
-
A continuous current rating equal to or greater than the sum of the full-load current of the fire
pump room accessories and the rated lock-rotor current(s) of the fire pump motor(s) (600
percent of the full-load current) if they operate off the same feed.
Interrupting capacity equal to or greater than the maximum fault current possible at the location
of the fuses as determined by a qualified electrical engineer.
A locked panel door to ensure non-tampering by unauthorized persons.
A circuit breaker, if used, shall have:
-
-
5.6.5
The breaker shall have an instantaneous trip only. It shall not have an “over-load” trip
mechanism.
The continuous current rating equal to or greater than the sum of the full-load current of the fire
pump room accessories and the rated lock-rotor current(s) of the fire pump motor(s) (600
percent of the full-load current) if they operate off the same feed.
Interrupting capacity equal to or greater than the maximum fault current possible at the location
of the breaker.
The instantaneous trip setting shall be at least 12 times the full load current rating of the fire
pump motor. An instantaneous trip setting as high as this is necessary because “spikes” or
current surges may occur if the motor(s) attempts to start at the peak of the current cycle. This
is considerably above the calculated trip setting, but is accessible because it is intended for short
circuit protection on the feeder conductors where a short circuit can draw current in excess of
this value. This setting is shown on the nameplate of the over-current device.
A locked panel door to ensure non-tampering by unauthorized persons.
Any manual disconnect switches shall be in a locked box or locked in the closed position
Motor and Diesel Engine
5.6.5.1 Electric Motor
Motors shall operate smoothly without excessive vibration.
Voltage shall not exceed 110 percent of the motor’s rated voltage and shall not drop more than 5 percent
below the motor’s rated voltage when the fire pumps are being driven at rated conditions while the
conductors between the power station(s) and motors are carrying peak loads.
Standard 104
15
The “running” timer shall be set for approximately one-minute per ten horsepower to allow the motor
windings to cool.
When operating at peak electrical load (about 140 to 150 percent of the flow capacity) the fire pump
shall be shut down and then restarted. The “in-rush” motor current will be the same as when cold, but be
of greater duration since the fire pump will come up to speed more slowly.
Motors used above an altitude of 3,300 feet shall be de-rated according to altitude.
manufacturer for information.

5.6.5.2 Diesel Engine
The flow of the fire pump may not adequately test the engine. After the fire pump has been flow-tested
satisfactorily, water flow shall be adjusted for peak power requirement (about 140 to 150 percent
capacity), and allowed to run for 15 to 20 minutes to demonstrate that the engine will not overheat under
this condition. Cooling water shall be arranged to discharge to a safe location with no possibility of
flooding the fire pump room even during a power failure.
After the engine has operated for approximately 30 minutes (for the flow test), it shall be started and
stopped 10 times in succession to test both manual and automatic operation.
The engine-speed governor shall be adjusted and secured to maintain fire pump load, or approximately
140 to 150 percent of the rated fire pump capacity. The governor must control the speed with no more
than a 10 percent variation between maximum fire pump load and shut-off condition (churn).
The overspeed governor shall be set at approximately 120 percent of the rated fire pump speed. When
possible, check this setting by operating the engine above rated speed. It is important that the setting is
high enough to prevent shutdown of the engine during start-up. This device must be reset manually after
each over-speed shutdown.
Diesel engines shall be wired to not shut down automatically when they over-heat or when the
lubricating oil pressure is low. Warning alarms indicating these conditions shall be provided.
Fuel supply tanks shall have a capacity at least equal to one (1) gallon per horsepower, plus five (5)
percent for volume expansion and shall be dedicated to the fire pump diesel engine. Tanks shall be
inspected for leaks and to verify that the diesel fuel level is full. Multiple diesel fire pump installations
shall have individual fuel tank supplies.
5.6.6
Accessories
The installation and setting of the main relief valve shall conform to NFPA No. 20. To prevent
overheating, a circulation relief valve adjusted to open at approximately 5 PSI below the minimum shutoff (churn) pressure, or suction at the lowest point, is needed to provide a small water flow through the
fire pump when it is operating with no other discharge.
A horizontal fire pump and driver require a flexible coupling and safety guard in the shaft between them
to compensate for any slight misalignment, and to provide shaft-end clearance to compensate for heat
induced shaft expansion. This is usually a simple loose pin coupling. NOTE: It is very important that
the alignment of this coupling be checked before conducting the annual flow test.
The fire pump shall be subject to at least one full hour of continuous operation to prove that bearings and
packing boxes are in good condition, and will not over-heat. Packing glands on horizontal fire pump
shafts shall be adjusted so that water drips freely or “runs” in a thin stream to cool, lubricate and provide
an air seal.
A fire pump shall not be operated when dry or unprimed, nor shall it be allowed to “churn” for more
than three to five minutes without water circulation. The closely fitted seal rings can overheat, and cause
damage to the fire pump.
Standard 104
16
Other accessories include:
5.6.7
Suction and discharge pressure gauges
Flanged type waste cone
Capacity nameplate
Control Panel Functions
All control panel functions shall be tested. If the fire pump house is not constantly attended, alarms shall
be transmitted to the on-site central supervision station (proprietary signaling system).
Typical alarms indicate:
-
-
Fire pump “running” (started)
Loss of operating electric power
Phase reversal on line side of the motor
Low fuel supply
Controller main switch in “off” or “manual” position
Engine trouble such as
Low lubricating oil pressure
High engine temperature
Failure of engine to start (over-crank)
Engine over-speed shutdown
High water temperature
Battery failure
Control valve tampering
Relief valve open
Fire pump room trouble (unauthorized entry)
Low temperature in fire pump room
Suction supply water level below normal
Suction supply water level near depletion
If these alarms have a common audible signal, each condition shall be visually shown (individually) at
the fire pump house controller, and at the on-site central supervision station.
5.6.8
Suction
Multiple fire pumps taking suction from a single water source shall be operated simultaneously at
maximum flow to verify that the fill pipes are unobstructed, and properly sized to maintain an adequate
water level.
5.6.9
Jockey (Pressure Maintenance) Pump
Jockey pumps are used to maintain a uniformly high pressure on the fire protection system to:
-
Assure high pressure on initially fused sprinklers.
Permit the fire pump to start at a high system pressure so that water hammer will be less likely
to occur.
Avoid frequent and unnecessary starting of fire pumps because of minor fluctuations in the
system pressure.
Prevent false alarms caused by surges in the public water supply.
Jockey pumps can be used for applications as small as an individual sprinkler system, or for an entire
underground system. The jockey pump shall be rated (capacity and pressure) to provide a flow
approximately twice the rate of anticipated or experienced leakage in the system at the pressure
corresponding to the “off” setting of the controller for the fire pump.
The jockey pump and controls arrangement shall be designed in accordance with NFPA No. 20.
Jockey pumps may be of either the centrifugal or positive displacement type.
Standard 104
17
To prevent over-pressurizing and damage the system, the maximum possible discharge pressure of the
jockey pump shall be less than the pressure rating of the system. A positive-displacement jockey pump
shall have a relief valve bypass (internal or external) that is set to prevent a pressure in excess of the
system rating.
5.6.10
Additional Criteria
-
-
Standard 104
Pressure shall not exceed the pressure rating of the system (usually 150-PSI).
The fire pump shall be arranged to start at a pressure close to its maximum possible discharge
pressure (as installed) to avoid water hammer.
The fire pump shall be arranged to start before sprinkler system pressure drops below designed
operating pressure.
The fire pump shall be arranged for automatic start and manual stop.
The jockey pump shall be arranged to start at a pressure above the starting pressure setting of
the fire pump (approximately 10-PSI) to prevent false starts of the fire pump.
A pressure differential between the “start” and “stop” settings of the jockey pump (10 to 15
PSI) is required to prevent unwanted fire pump motor/engine starts.
The controller for the jockey pump shall incorporate a running-period timer (set for
approximately 1 minute per 10 horsepower) to allow for cooling of the electric motors, unless it
can be determined that the normal “running” cycle will equal or exceed that period.
Weekly “run” criteria for fire pumps is
Ten (10) minutes – electric motor driven (normally fire pump is operated for one
minute per 10 horsepower rating of the motor.
Thirty (30) minutes – diesel engine driven

Sprinkler Systems
General
Equipment maintenance shall be conducted in the form of flow and pressure tests. A flow test involves
testing of all system components of a sprinkler system.
Satisfactory test results shall be recorded by the testing contractor and shall be maintained by the
Wackenhut Site Security Manager.
6.2
Flushing (as required)
All sprinkler system piping and lead-in connections shall be flushed to remove foreign material from
supply mains and branch lines. Flushing shall continue until the water flows clear. Care shall be
exercised during the flushing operation to assure that water flow will adequately drain without producing
water damage to property.
Flow rates, in accordance with the 2002 edition with NFPA No. 13, Table 10.10.2.1.3 are:

System Waterflow Tests (annually)
Water flow tests shall be conducted for each sprinkler system to verify that the water supply and
sprinkler system piping are in operating condition. A two-inch main drain at the sprinkler riser acts as a
water supply test pipe by activating the system (opening the alarm or check valve).
System pressure shall be recorded by observing the system pressure gauge at the alarm or check valve.
Pressure on the system side of the alarm or check valve may be higher than that of the water supply
because any momentary high pressure on the supply will be transmitted to the system and retained by the
check valve. This excess pressure is relieved when a water flow test is conducted.
Residual pressure (below static pressure) shall be recorded by opening the two-inch main drain and
observing the system pressure gauge at the valve.
A flow test shall be conducted for each system.
Water supplies and systems shall be returned to service after testing is satisfactorily completed.
6.4
Sprinklers and Piping
A visual inspection shall be conducted of all sprinkler heads and piping to assure that they are properly
installed, not obstructed and that proper clearances from structural members are maintained per the 2002
edition of NFPA No. 13.
Piping shall be visually inspected to verify that nothing is supported from it.
Standard 104
19
Sprinklers shall not be obstructed by high piled stock storage, other materials, by partitions, or walls that
might prevent free and proper water distribution. A clear space of 18 inches is required between the topof-storage and sprinkler deflectors for storage up and equal to 12 feet. For storage above 12 feet and for
ESFR and Large Drop sprinkler systems, the minimum clear space shall be 36 inches.
Only new sprinklers shall be used for installation installed in accordance with this Standard. Ensure that
previously installed sprinklers are not re-used for new installations. Observe the type of sprinkler, year
manufactured and date of installation.
Verify that all sprinklers are of the proper temperature rating and type for their intended use. Replace
upright sprinklers with upright sprinklers and pendent sprinklers with pendent sprinklers. Also, verify
orifice size and not just thread size.
Sprinklers shall be protected against coating of paint, excessive deposits or incrustations or corrosive
conditions should any of these conditions exist. Optional methods are:
Do not use thin bags over sprinklers in spray paint booths where high pressure water is used to clean the
booths.
Plastic Bags over sprinklers - 0.003-inch (0.076-mm) cellophane secured with rubber bands.
NFPA No. 13, (2002 edition) “Standard for Installation of Sprinkler Systems”, requires that
hydraulically designed sprinkler systems each have a permanent non-corrosive sign attached to the given
sprinkler riser that states the design criteria and system demand. Permanently marked on these signs will
be the location of the design area, discharge density and remote area, required flow and residual pressure
at BOR, occupancy class or commodity class, and hose demand system demand.
6.5
Dry Pipe Sprinkler Systems (conducted yearly by a contractor)
Maintenance tests for dry pipe systems consist of system operation (water-flow test) through use of the
inspector’s test connections.
Water flow tests shall be conducted for each dry pipe sprinkler system to verify that the water supply and
sprinkler system piping are in operating condition.
System pressure shall be observed at the alarm valve pressure gauge.
Verify that the proprietary signaling station is notified within 60 seconds. Silence alarms when tests are
completed.
Water supplies and systems shall be returned to service after testing is satisfactorily completed.
Quick opening devices shall be provided and shall be functional to boost air release from system piping
to lessen time between valve trip and water discharging from the inspector’s test connection. These are
usually required for dry pipe system with an interior pipe capacity (volume) of 500 gallons or more.
6.6
Pre-action/Deluge Sprinkler Systems (contractor)
Pre-action and deluge systems are designed to protect properties where danger of water damage exists as
a result of automatic sprinkler system damage. Deluge systems are used when high water volume
sprinkler system is required.
Deluge systems differ from pre-action systems in that deluge systems have open sprinkler heads, and
pre-action systems have closed sprinklers heads. Both types of systems are operated by an automatic
detection system.
The principle difference between a pre-action and a standard dry pipe system is that in a pre-action
system, the water supply valve is actuated not by air release, but actuated independently by operation of
an automatic fire detection system. The valve can also be operated manually.
Maintenance tests for pre-action and deluge systems consist of testing the detection system, valve
solenoid, flushing, and main drain test.
Standard 104
20
Water flow tests shall be conducted for each pre-action/deluge sprinkler system to verify that the water
supply and sprinkler system piping are in operating condition.
System pressure shall be observed at the alarm valve pressure gauge.
Verify that the proprietary signaling station is notified. Silence alarms when tests are completed.
Water supplies and systems shall be returned to service after testing is satisfactorily completed.

High Speed Water Spray (Deluge) Systems
General (conducted annually by contractor)
High Speed Water Spray systems are used for high volume water-flow requirements in high hazard
areas. Water Spray systems are used to protect spray paint booth operations where large quantities of
water are needed for fire suppression. NOTE: Water Spray systems are also used at openings in
firewalls where fire doors can not be installed.
High Speed Water Spray nozzles are open and water flows from all nozzles when the control valve is
opened.
The control valve is opened as a result of a fire detection system. CFS No. 101 requirement is to use
optical infrared detectors (IR3) instead of ultraviolet (UV) detection. Water is applied in a designated
pattern, velocity, particle size and density, using special nozzles that generally provide a solid cone of
water to a precisely defined area.
High-Speed Water Spray (Deluge) systems differ from a standard deluge sprinkler systems. High Speed
Water Spray systems have open, high volume, nozzles that distribute water in a denser water curtain
pattern and standard deluge sprinkler systems have open sprinkler heads that distribute water in a more
conventional pattern, satisfying other design criteria. Both types of systems are operated by an
automatic fire (or smoke) detection system.
Functional and flow tests shall be performed on all operating systems including the detection system,
valve solenoid, automatic shutdown of equipment, flushing, and main drain test.
A flow test shall be conducted to flush the system using down commers. When more than one system
operates in the event of fire in a given fire zone, all systems shall be simultaneously flow tested.
Satisfactory test results shall be provided by the testing contractor and shall be maintained by the
Wackenhut Site Security Manager.
7.2
Flushing (as required)
All sprinkler system underground piping and lead-in connections shall be flushed to remove foreign
material from supply mains and branch lines. Flushing shall continue until the water flows clear. Care
shall be exercised during the flushing operation to assure that water flow will adequately drain without
producing water damage to property.
Flow rates, in accordance with the 2002 edition of NFPA No. 13, Table 10.10.2.1.3 are:

Foam Water Sprinkler Systems (AFFF)
General
Aqueous Film-Forming Foam (AFFF) water sprinkler systems are used to provide fire suppression for
flammable liquids operation and storage areas. Standard sprinkler heads are used with AFFF systems, as
aspiration of air to form bubbles is not required, unlike mechanical foam. A foam proportioning system
is used to inject the foam concentrate into the water supply. For a specified period of time (10 minutes),
after the supply of foam concentrate is exhausted, the system will continue to discharge water.
Heat detectors generally activate systems, but other types of detectors or manual activation can be used.
Foam-water sprinkler systems are used principally for protecting flammable liquid hazards, such as
flammable liquid handling and storage, and spray paint operations.
Equipment maintenance shall be conducted in the form of flow and pressure tests.

After a pre-determined time delay (30 to 60 seconds), the system (zoned selector valve if low
pressure carbon dioxide) will discharge.
Upon verifying the cause of the alarm, the audible alarm may be silenced by momentarily
operating the “System Alarm Silence” switch.
After an alarm test, the system shall be reset.
High Pressure Storage
High-pressure containers (cylinders) are designed to store liquid carbon dioxide at atmospheric
temperature. Since maximum pressure in the cylinder is 800 to 1,000 PSI for carbon dioxide at ambient
temperature, the container shall be designed to withstand maximum expected pressure.
Storage cylinders are designed, tested and filled to U.S. Department of Transportation (DOT)
specifications. The maximum permitted filling density is equal to 68% of the weight of water that the
container can hold at 60 degree Fahrenheit. Cylinders are fitted with an internal dip tube so that liquid
will be discharged from the bottom when the cylinder is upright and the valve is opened.
Abnormally low storage temperatures would adversely affect the rate of discharge. For this reason,
storage temperature below 0°F for total flooding systems or below 32°F for local application systems are
not permitted.
9.3.5
Low Pressure Storage
Low-pressure storage tanks are pressure vessels with a designed working pressure of approximately 300PSI. Storage tanks are maintained at a temperature of approximately 0°F by use of insulation and
mechanical refrigeration. At this temperature, the pressure is approximately 300 PSI. A compressor,
controlled by a pressure switch in the tank, circulates refrigerant through the coils near the top of the
tank. Tank pressure is controlled by condensation of carbon dioxide vapors by the coils. In the event
refrigeration fails, pressure relief valves bleed off some vapors to keep the pressure within safe limits.
This permits some of the liquid to evaporate; creating a self-refrigerating effect that keeps the emergency
loss rate at a low level.
With low-pressure storage, it is common practice to protect multiple hazards from one central storage
tank. Opening and closing the discharge (selector) valves using a preset timed sequence controls the
quantity of carbon dioxide discharged in a protected area. Central storage tanks may have capacities
ranging from less than one ton to one hundred tons. For large protected areas, the distance between the
hazard and storage could be as much as several hundred feet.

Extended Discharge
An extended discharge of carbon dioxide is used when an enclosure is not tight enough to retain an
extinguishing concentration as long as it is needed. The extended discharge is discharged at a reduced
rate following the initial discharge used to develop the extinguishing concentration (within a two-minute
time frame). The reduced rate of discharge shall be a function of the leakage rate (calculated by leakage
area), or the flow rate, through ventilation ducts that cannot be shut down.
Extended discharge is particularly applicable to enclosed rotating electrical equipment such as
generators, where it is difficult to prevent leakage until rotation stops. Extended discharge can be
applied to ordinary total flooding systems as well as to local application systems where a small spot may
require prolonged cooling.

Detectors
10.3.1
Smoke Detectors
Smoke detectors are of two types; i.e., ionization and photoelectric. The only difference between the two
detectors is their method of operation (ionization detects an ionized atmosphere and photoelectric detects
a clouded photoelectric cell). Testing method is identical for both types of smoke detectors.
All smoke detectors are tested in the same manner. This test consists of spraying a smoke detector test
aerosol into the detector chamber. Each detector has a self-contained light that illuminates flashes or
loses illumination when the detector operates.
10.3.2
Heat Detectors
Heat detectors are of three types; i.e., fixed temperature, rate-of-rise, and rate compensated. Fixed
temperature detectors operate when the temperature of the operating element reaches a specified point.
Rate-of-Rise detectors operate when the rate of temperature increase exceeds a pre-determined level.
Rate compensated detectors operate when the temperature of the surrounding air reaches a predetermined level, regardless of the rate of temperature rise.
Heat detectors are tested by the application of heat (hair dryer) or by being “short” circuited.
Rate-of –Rise and rate compensation (heat) detectors can be tested using a hair dryer or shielded heat
lamp.
The following inspections shall be conducted on all installed equipment:
-
Standard 104
For damage or tampering that may interfere with its intended operation.
For functionality to ensure that it will function as intended under emergency operating
conditions.

Ultraviolet (UV) and Infrared (IR) detectors are flame detectors that sense UV or IR radiation
(wavelengths) from a fire source.
A functional test shall be performed on all UV and UV/IR and IR/IR detection systems. The functional
test shall be comprised of the detection system checkout procedure and testing of optical integrity and
detector module responses to UV and IR radiation.
The Automatic Optical Integrity feature checks the controller and all detectors in all zones
approximately once every second. This monitors the system for faults that may occur, including wiring
between detectors and the controller.
10.3.4
Beam Smoke Detection Systems
A beam detector detects smoke through a transmitter that sends a beam of infrared light to a receiver.
The received signal is analyzed for loss of strength caused by smoke obscuration when smoke
obscuration exceeds a pre-set level.
A functional test shall be performed on all beam detection systems.

visible from all points within the visual alarm area.
10.4.3
Voice Alarm Systems
The voice alarm system consists of a power supply, pre-amplifier, amplifier, loudspeakers, tape player,
tape and interconnecting wiring. Upon actuation of a fire alarm within the building, the tape player
sends a pre-recorded message over the voice fire alarm circuit.
The message is amplified and given to occupants through individual loudspeakers. Some voice alarm
systems use a live voice message spoken into a microphone at a central location instead of tape player.
Voice messages sometimes have pre-alert tones for drawing attention to the message that is to follow.
10.4.4
