What is a Conventional Fire Alarm System?


Conventional Fire Alarm System is regarded as traditional fire protection equipment. It is simpler among fire detection and alarm systems.

If you need a conventional fire alarm system you can easily get it from a store of our company ‘Fire Safety Trading Pvt Ltd. We understand your need for protecting your precious assets from fire hazards, therefore we provide all kinds of fire protection equipment at reasonable prices.

Let’s take a look at the structure and functioning of a conventional fire alarm system, which will assist you whether it meets your need or not.

The radial method is used in the wiring of conventional fire alarm systems. In this type of wiring, single legs of cable are used. The devices are connected to the main fire alarm panel, with the help of these radials, and work either as fire alarm zones or sounder circuits.

The other important thing about which it is necessary to know is fire alarm zones. These zones are reduced circuits and their function is to monitor the detectors and manual call points. More than one detector and call point can be connected with the zone circuits on each radial circuit.

The other thing we come across is sounder circuits. These are also radial circuits, but they are used to control different devices. Mainly, the sounder circuits control the fire alarm sounders and visual alarm devices (VADS). More than one sounder can be accommodated by these circuits. But the only limitation is the power consumed by the sounders, and the output that is provided to each sounder circuit by the main panel.

As we have seen that conventional system works on a simple method. If a fire hazard or fire incident, or fault occurs, we will be informed only about the fire or fault in an area, on that particular zone, which is controlling that particular area. You will also not be able to know which particular detector has signaled a fire or some fault. So, a conventional fire alarm system is unable to highlight the precise location of a fire incident or a circuit fault and will let you know only about the zone.

Due to the above-mentioned reason, it becomes a difficult and time taking process to get to the location where a fire outbreaks.  Then the firefighters have to do a lot of effort to reach the exact location. Consequently, more time is consumed in finding a fault or the fire, when we are using a conventional fire alarm system, another drawback is when you find the fault you need more money to fix it. Although this fire alarm system and its devices can be purchased at low prices their maintenance prices are high.

In a conventional system, there is a need for two separate radial circuits, for operating both sounders and detectors, therefore its installation cost is higher than the Addressable Fire Alarm system. The installation price is high because of the wire quantity used in the installation of these fire alarm systems. Comparatively more amount of wire is used in installing the conventional fire alarm system than the addressable fire alarm system.

In electronics, conventional fire detection and alarm systems are regarded as basics, because their way of functioning is simple. The cost expenses in manufacturing this system are comparatively less than an addressable system. As its building amount is lower, so it means that the consumers can purchase it at a cheaper rate. In this way, it becomes a beneficial and affordable fire protection solution to install in smaller premises like shops, small garages, and small schools.


How does a Conventional Fire Alarm System work?


When the detectors detect smoke, fire, or a fault it gives signals to the main panel. Then the main panel orders the sounder circuit to get activated and produce audible sounds for alerting the people around. The VADS also displays the zone, where the fire outbreaks or a fault occurs. Manual call points also help in the function.  All this process helps to access the location and take control of the danger.


The Advantages/ benefits of the Conventional Fire Alarm system:


There are a lot of benefits that you can consider, and go for this type of fire protection and alarm system. Such as:

1- The whole system along with its devices, can be purchased at a low cost.

2- it functions simply; therefore, it is easy to use.

3- It is worthy of installation in small buildings.


Disadvantages of the conventional fire alarm systems:


1- It does not fulfill the need for fire protection in larger buildings.

2- You cannot get to know the exact location of a fire incident or a technical fault, instead only the zone is highlighted.

3- A lot of wiring is required as compared to the Addressable Fire Alarm systems.


Zoning for Safety:


As you have seen in the working of a conventional fire alarm system, it highlights the zone. The zoning for safety means, that a whole building is divided into several smaller zones to connect them with the fire alarm systems. In this way, it becomes easier to identify the area where are fire hazards or any other fault occurs. If the fire alarm system catches the signal of danger from a specific zone, the devices, and detectors controlling that zone will tell about the outbreak. When that particular zone will be highlighted the firefighters can easily reach there in less time to take control of the outbreak and reduce the chances of expected risk.

The buildings and sites are divided into zones, this zoning for safety is very beneficial for ensuring a safe life. The making of zones at work sites will reduce accidental spreads of different chemicals, and the zoning in the commercial buildings will protect the assets and people. The other purposes of zoning the areas include:

1- A work task is being happened in that zone.

2- If a hazard occurs, that zone is separated.

3- The areas that contain sensitive information are also separated as the zone and the visitors are prohibited.

There are three types of zoning for safety:


1- The exclusion zone:

The exclusion zone is also known as the Hot zone. It is the area where the chemicals are some other contaminations are placed.

2- The Contamination reduction zone:

It is also known as the warm zone; it comes between the exclusion and support zones.

3- The support zone:

It is also known as the cold zone; it is free from any kind of contamination or chemicals that can spill and can be hazardous. So, everyone is allowed to visit it.
