Main Components of Fire Protection Systems


Fire companies generally use different components, fire suppression system and set of equipment in a single fire protection system of a building to cover and protect against fire hazards. We can imagine automated sprinklers and fire alarm system where fire protection is discussed. They are, only two of the many systems designed to protect a building and its occupants. Accumulated smoke, for example, might lead to asphyxiation and must also be checked with extractor fans. Facilities should also incorporate firefighter assistance measures because there are occasions where fire with sprinklers and fire extinguishers alone cannot be controlled.

It is simply an informational guide to provide an overview of the critical components utilized in fire protection systems.

Fire Sprinklers

A large-scale automatical sprinkler system can cost a lot, but it’s a lot more expensive to restore unchecked fire damage caused in absence of sprinkler systems.Occupying persons may also suffer disabled injuries or perhaps die in a fire.

Sprinkler are required in new residential towers, or existing towers that undergo a major renovation. Fire sprinklers are mandatory for existing office buildings.


A standpipe is a tube system that supplies water from a primary source to hose connections throughout a building at important areas. Firefighters use these outlets during fire fighting.

Dry pipes are usually filled with compressed air and, when necessary, the water enters the system, while wet pipes are filled permanently with water. Automatic systems alone establish the necessary flow, while manual systems rely on the pumping truck. Semi-automatic systems have to have a remote signal activated, but once this happens they can establish the required flow.

Fire Alarm Systems

The building is controlled by a fire alarm system to detect fires, generating audibles and visual indications. An automatic or manual control unit takes inputs from all fire detectors and activates the associated reporting systems. Furthermore, fire alarms can be employed for appropriate fire detection reaction procedures.It is vital to remember that, depending on the building occupancy classification, fire alarm regulations fluctuate dramatically.

Smoke Control Systems

Human beings prevent fire from instincts, although smoke-related problems are unusual. Smoke can lead to poisoning, besides reducing visibility, if sufficient quantities are inhaled. A fire protection system must therefore properly deal with smoke, prevent its growing build-up and remove it.

Note that the movement of smoke is caused by pressure and temperature: from lower pressure to higher pressure range, you will not witness smoke flow, which usually increases as the hot air increases.

Fumes may be mechanical or passive and compliment each other systems:

  • Mechanical systemsmanipulate smoke flow pattern.
  • Passive systems Smoke barriers are used in passive systems to limit themobility of smoke without any power consumption.

The fire maintenance of elevator shafts and steps is one of the most significant criteria for a smoke-control system. These places are utilized to evacuate the building, and accumulation of smoke can make it harder for people to escape.

Post-Fire Smoke Purge

As indicated above, fumes obstruct visibility and are exceedingly harmful when inhaled. Clearing the smoke in a structure is vital after the fire is out, to restart functioning as soon as feasible. This is exactly what post fire smoke purge systems meant to quickly removes smoke from the structure.

Because fire-purging systems work after a fire, they are not regarded as safe systems for life. In all occupancy groups specified in the fire protection code, however, they are compulsory.

Fire Pumps

As you could imagine by the name of the fire pumps, a reliable fire protection system water supply is established. When a fire pump supplied water just to an automatic sprinkler system, the sprinkler booster pump is considered.

Please note that electricity usually drives fire pumps. The criteria for fire pump backup power systems, assuring their operation even when electricity is interfered with.

Fire pumps are expensive, yet for all fire safety systems they are not mandatory. With intelligent design considerations, their total use may be avoided while still having a dependable system that complies with code.

Auxiliary Radio Communication System (ARCS)

An ARCS is a firefighter communication system which fulfils the following requirements:

  • Wireless
  • Bidirectional
  • Exclusive interference prevention radio frequencies
  • Independent of electrical systems and building communication systems


In all new commercial buildings over 75 feet and new residential buildings above 125 feet, the ARCS is obligatory. It must ensure optimum building protection and equip firemen with a dependable communication system throughout the building.
