The sprinkler system is designed
to extinguish the fire entirely, or to prevent the spread of the fire. An automatic sprinkler
system consists of a series of —- at or near the —- in a building.
pipes/ceiling

The (automatic) sprinkler
system is fitted with automatic devices designed to release water on a fire. These devices
are called —-
sprinkler heads

The sprinkler heads are normally closed by a —-or a —-
disc/clap

This
cap is held in place by a heat sensitive releasing element. A —- to a
predetermined level causes the sprinkler head to open.
rise in temperature

This
cap is held in place by a heat sensitive releasing element. A rise in temperature to a
predetermined level causes the sprinkler head to open. Water is then discharged in the
form of —-. When the sprinkler heads open they are said to have —-
spray/fused

The sprinkler
heads are fitted at standard intervals on the piping. If more than one head opens, the area
sprayed by each overlaps that of the —-
sprinkler head next to it.

Sprinkler systems are—- in various occupancies

cold weather valves

A sprinkler system employing automatic sprinklers that are
attached to a piping system containing air or nitrogen under pressure, the release
of which (as from the opening of a sprinkler) permits the water pressure to open a valve
known as a dry pipe valve, and the water then flows into the piping system and
out the opened sprinklers.
Dry Pipe Sprinkler System

Dry Pipe Sprinkler Systems are installed —-
since the protected area cannot be heated to prevent freezing conditions. In

The preaction
valve can also be operated
manually

The preaction system has several advantages over a dry pipe system
The preaction valve
opens sooner because the fire detectors react to heat changes faster than sprinkler heads.

Fire and water damage may be decreased because water is sprayed on the fire more quickly
the alarm signal is given as soon as the preaction valve is opened.

Heat responsive devices are commonly used to trip pre-action valves. These devices are
also used to activate alarm and supervisory systems. There are three main devices used to
trip pre-action valves:
1) devices designed to operate at a fixed temperature; 2) devices
designed to operate when the temperature in the room increases a set amount in a given
time period (rate-of-rise), and 3) devices combining fixed temperature and rate of rise
devices.

Other ways to activate a preaction valve are
smoke detectors, gas detecting
systems, hydraulic, electric, manual release, and automatic signals from other safety
systems.

A supervisory device signals when the valve has opened that will automatically
sound an
alarm.

special kind of preaction system is a
recycling system for controlling sprinklers. This system shuts off the water when the fire
has been put out or the heat drops. If the fire rekindles or the heat rises sharply, water is
discharged again. The system continues cycling on and off as long as the fire persists.
Preaction System with a Recycling Feature

These systems have the basic features of
both types of systems. The piping system contains air under pressure. A heat detecting
device opens the water control valve and a quick opening device. The system then fills with
water and operates as a wet pipe system. If the heat detecting system fails, the system will
operate as a standard dry pipe system.
Combined Dry Pipe and Preaction Systems

VIII. WATER SUPPLIES FOR SPRINKLER SYSTEMS

Sprinklers may be supplied from one or a combination of sources. For example, they may
be supplied by
public mains, gravity tanks, pressure tanks, fire pumps, reservoirs, rivers,
or lakes.

A —- water suppy a would appear to be all that is needed to supply a sprinkler
fire protection system. This assumes that there is enough water at an acceptable pressure.

single supply may be out of service (for maintenance or repair) during a fire
emergency or it may be disabled during fire or before the fire is fully extinguished.
Additionally, the water supply may fall below normal pressure or volume during an
emergency.

In some cases it is required by law to have a secondary water supply source. Whether a
second source is needed depends on several factors. These factors include
the strength

fire protection systems.
Fire pumps

Fire pumps can be used in combination w/
with municipal water supply,
suction tanks and gravity tanks to supply sprinkler system.

Fire pumps are designed to
take the water from a supply source and then discharge the water into the fire protection
system under pressure. The amount of pressure with which the water is discharged from
the pump is called the —- head.
total

The total head is measured in —-
psi

The higher the psi rating of the pump the greater the —- discharged
pressure

Fire Pumps shall be sized to satisfy the —- requirements of the
water based fire protection system.
hydraulic

Automatic fire pumps must have their suction “under a —-head” to draw water from a
supply source.
positive

Under positive head simply means that the water supplying the pump
must be fed into the fire pump under—-
pressure

Under positive head simply means that the water supplying the pump
must be fed into the fire pump under pressure. This can be achieved by connecting the fire
pump to a —- tank.Water is forced into the pump because of gravity

IX. WATER-FLOW ALARMS AND SPRINKLER SYSTEM SUPERVISION

Sprinkler systems should have devices and equipment for signaling when water flows through—- or —- supplying the systems.
risers/mains

Functions of Alarms and Supervisory Signals

A sprinkler system with a water flow alarm serves two functions:
1) It is an effective fire extinguishing system, and 2) It is an automatic fire alarm. An alarm is signaled soon after a sprinkler head has opened. This is important since it allows the occupants’ time to leave the building. It also signals that the Fire Department should be summoned.

Waterflow alarms and fire alarms give warning of the actual occurrence of a fire. They also signal when
water flows through the system due to broken pipes.

Alarms alert occupants and summon the
fire dept

Any signal, whether water-flow or supervisory, may be used to sound an audible local sprinkler alarm. It may also send a signal to the
central station company

In systems equipped with central monitored connections the central station company shall be notified when any control valves are
closed for maintenance and repair. This practice reduces false alarms.

Sprinkler systems are required to have an approved water —- or an —–, —–, or —- on the outside of the building.
water motor gong or an electric bell, horn, or siren on the outside of the building.

An electric bell or other audible signal device may also be located
inside the building

Water operated devices must be located near the
alarm valve, dry pipe valve, or other water control valves in order to avoid long runs of connecting pipe.

Devices and Equipment Supervised

. Sprinkler system supervision is commonly provided for several purposes. They are used to
1) water supply control valves, 2) low water level in water supply tanks, 3) low temperature in water supply tanks or ground level reservoirs, 4) high or low water level in pressure tanks, 5) high or low air pressure in pressure tanks, 6) high or low air pressure in dry pipe or pre-action sprinkler systems, 7) failure of electric power supply or phase reversal to fire pumps and, 8) automatic operation of electric fire pumps.

The basic design of most water-flow alarm valves is that of a —- valve which lifts from its seat when water flows into a sprinkler system. This alarm
then starts an audible signal to alert the occupants in the building that the sprinkler system has been activated.
check

—-Switches have a paddle inserted inside the main supply piping perpendicular to the direction of flow. Upon waterflow, the paddle switch transmits an alarm.
Vane type waterflow –

Vane type water-flow switches shall not be installed to monitor
waterflow in dry pipe or pre-action sprinkler systems.

An alarm check valve that is exposed to changing water supply pressure needs an alarm retarding device.
Alarm Retarding Devices

n alarm check valve that is exposed to changing water supply pressure needs an alarm retarding device. This is required to prevent false alarms when the check valve clapper is
lifted from its seat by a temporary pressure surge.

Vane type water flow switches sensitivity can also be adjusted to
changing water pressures.

X. SYSTEM COMPONENTS

Sprinkler heads are made of metal. They are screwed into the piping at
standard intervals.

BUILD-UP OF FOREIGN MATERIAL ON SPRINKLERS

Sometimes conditions exist which cause a build-up of foreign material on sprinkler heads. This may prevent the sprinkler head from working properly. This build-up is commonly called—-The build-up of foreign material insulates the sprinkler head. This build-up prevents the sprinkler from opening at the desired temperature.

MIC

An obstruction investigation shall also be performed whenever the following conditions exist such as
pinhole leaks, a record of broken public water mains in the vicinity, foreign material in water discharged during drain tests or plugging of inspector’s test valve connection. A complete list of system conditions requiring obstruction investigation are listed in Chapter 14 and Annex D of NFPA #25 2011 edition.

Unlike other extinguishing agents – water, dry chemical, CO2, etc., a stable aqueous foam can
extinguish a flammable or combustible liquid fire by the combined mechanisms of cooling, separating the flame/ignition source from the product surface, suppressing vapors and smothering. It can also secure for extended periods of time against reflash or re-ignition. Water, if used on a standard hydrocarbon fuel, is heavier than most of those liquids and if applied directly to the fuel surface, will sink to the bottom having little or no effect on extinguishment or vapor suppression. If the liquid fuel heats above 212ºF, the water may boil below the fuel surface throwing the fuel out of the contained area and spreading the fire.

Foam fire extinguishing systems shall be periodically inspected, tested and otherwise maintained in accordance with information described in this study material as well as
NFPA 25 (2011), NFPA 11 (2005), as modified by Fire Code Appendix B, and NFPA 16 The Standard for Installation of FoamWater Sprinkler and Foam-Water Spray Systems (2007), as modified by Fire Code Appendix B, and manufacturers listing.

Foam Systems are used primarily for —- protection be operated both manually and automatically to protect both Class —- and Class —– hazards using low expansion foam.
property/ A&B

Foam is very effective and is the most common method of fighting fires in fuel oil storage. Foam is created by mixing a —-%foamite concentrate with water and air.

FOAM TYPES ARE SUBDIVIDED INTO THREE RANGES:
1) Low-expansion foam uses foam to solution volume ratios up to 20 to 1

2) Medium-expansion foam uses foam to solution volume ratios from 20 to 1 to 200 to 1

3) High-expansion foam use foam to solution volume ratios from to 200 to 1 to approximately 1000 to 1.

It is important to note that different foam manufacturers may not produce foam solution that is compatible with each other. Great care must be exercised when testing and maintaining these systems to be certain that all the equipment is listed to be used together.

Foam-Water Sprinkler Systems and Foam Water Spray Systems use —-expansion type foams and are connected to a source of foam concentrate and an —– water supply.
low/automatic

The method of fire extinguishment is by covering the —-cutting off the oxygen supply to the fire along with cooling the fuel due to the water content of the mixture.
fuel

Foam solutions are not an effective extinguishment agent for fires involving
compressed gases, flammable metals or electrical fires due to the water contained in the mixture

Foam solutions do have the potential to pollute water supplies and great care should be taken to contain foam solution run off where applicable. When possible, foam concentrate shall be recycled back into the —- during the maintenance procedures.
