What are the components of a fire protection system?

The primary components we will examine are fire alarm systems, fire detection and notification systems, suppression agents and systems, water distribution systems, automatic sprinkler systems, standpipe and hose systems, and portable fire extinguishers.

What is Fenwal system?

The Fenwal system uses a slender inconel tube packed with thermally sensitive eutectic salt and a nickel wire center conductor. [Figure 9-4] Lengths of these sensing elements are connected in series to a control unit. This current flow is sensed by the control unit, which produces a signal to actuate the output relay.

What is Inergen system and its components?

The composition of INERGEN consists of mixtures of Nitrogen, Carbon Dioxide, and any one of the Inert Gases including Helium, Neon, Argon, Krypton and Xexnon. The most common composition is derived from a mixture of Nitrogen (52%), Argon (40%), and Carbon Dioxide (8%).

What is a halon fire suppression system?

Halon is a liquefied, compressed gas that stops the spread of fire by chemically disrupting combustion. Halon is an extraordinarily effective fire extinguishing agent, even at low concentrations. According to the Halon Alternative Research Corporation: “Three things must come together at the same time to start a fire.

What is the most important component of fire?

3 Things a Fire Needs

Heat. Heat is the first and most essential element that a fire needs. A fire can’t even start or spread unless there’s a significant amount of heat involved.
Fuel. Fuel is the second element found in the fire triangle.
Oxygen. Oxygen is the last element in the fire triangle.

What are the two types of smoke detectors used in aviation?

Another type of fire system that is used on aircraft is smoke detectors. There are two types of smoke detection systems such as light refraction type and ionization type.

What gases are used for pneumatic fire loop system?

When heated to its fire alarm temperature, a pneumatic element releases hydrogen gas from its titanium hydride core which trips the pressure switch in the responder unit and signals an alarm.

Which gas is used in Novec system?

There are several different kinds of gases that can be used to suppress a fire. Some of the most common gases used in fire suppression systems are: Carbon dioxide (CO2) Clean agents, including HFC-227ea (FM200) and FK-5-1-12 (Novec 1230)

What gases are used in Inergen systems?

The final gaseous clean agent is called Inergen. This system uses inert gases—such as nitrogen, argon, and carbon dioxide—to reduce the oxygen level around the fire and suppress it in the process. The concentration of gases used in Inergen systems is safe to use around people.

Why is Halon banned?

While Halon is considered a clean agent by The National Fire Protection Association because it’s electrically non-conducting and does not leave a residue, Halon has an extremely high potential for ozone depletion and contributes to global warming potential. …
