Fire alarm system invention

Everyone in our world should know how to protect his valuable assets. Fire alarm systems are design for this purpose. Everyone should know the fire detection system basics to apply them in his life.

Fire detection systems are to be considered one of the most valuable inventions that were invented by human beings.

In the united states of America, in the year of 2017 there was an estimate of $10.7 bn damage in property happened as a consequence of fire, a property loss average of $21,463.

(Source: Losses in the United States During 2017 report by NFPA).

Couldn't we avoid all these problems?

The answer is yes and a lot of property damages would be avoided and many lives would be saved if we installed suitable fire alarm systems (that are well designed) and if people were aware of the importance of such alarm systems and they had a good understanding of implementation of fire detection systems.

Fire detection systems installation

Once you are aware of the importance of the fire detection systems, then the next step is to determine: what type you are going to implement?

We have two main types of detection systems world wide:

1- Conventional system

2- Addressable system.

Both systems have a lot of similarities; nevertheless the main difference between them is that in the addressable system each individual detector or a manual call point has a unique address. This unique address allows the alarm control panel to identify the detector itself in case of real fire. Also in the main control panel you can label the detector and give its address a name with the suitable label you want (ex: building 2, floor 6, room 1).

The specific address label which is given to each detector will make firefighters reach the place faster and deal with the fire and minimize any damages that might occur.

In the contrary the conventional fire alarm system doesn't give you an address for each individual detector; instead it gives you a whole zone address which could contain 15 detectors. The conventional zone will give the same address to all of the detectors in the zone. A short come of the conventional systems is it can't identify the exact alarm detector in case of real fire and the firefighters will spend much effort to reach the exact place of the detector that triggered the alarm.

One positive point of the conventional alarm systems is that they are cheaper than the addressable one. So if your application is a small size application (about 4 areas), you may choose to apply the conventional method as it is cheaper and you don't need to address each individual point of the system.

Fire alarm system design

Once you finish choosing the suitable alarm system, now you are going to design it. The design of a fire detection system is to follow the authority having jurisdiction (AHJ) in your country which is described in a national code. The country national code is the basic reference for the alarm designer in the design phase.

The national code states the recommended distance between the detectors, placing of heat and smoke detectors, the recommended testing and inspection steps… etc.).

The well known national codes are:

  • American code NFPA 72
  • European code EN 54
  • British code BS 5839

You should also consider the choice of detection type relevant to the application. For instance you shouldn't use smoke detection method in the kitchen appliance as there will be a lot of smoke generation. Hence the suitable detection method is the heat detection with ac certain threshold value.

Fire alarm test

After the design and installation of a suitable systemFree Articles, you should perform periodic testing for your system. The testing is done to every component of the system including the main control panel.

Testing is performed using special testing devices that are able to generate smoke or heat according to your applied system. The testing is performed by trained personnel with predetermined testing procedure. The testing result should be recorded in a result sheet and to be filed for historical data analysis.

Finally fire detection systems' basics should be taught to each person in schools and educational entities as they are very valuable and property and live savers.
