Automatic Fire Alarm Systems: The Dawn of a New Era
Fire safety precautions and measures are a big concern today worldwide. Emergency services and fire alarm panels are designed in a way to alert people about the fire as well as to control the situation. In the concentrated situation of urban areas and with upcoming office complexes, shopping malls, hospitals, hotels and many such buildings – it has become necessary to follow the safety and precautionary measures for fire accidents. To serve the purpose, fire alarm system is an advanced and fool-proof technique.
A few years back, we were familiar with various manual techniques to alert people in case of fire. And the same practices were used to control the speed of the fire. After an era of manual pull buttons, glass stations and many such techniques, we have come across automatic fire alarm panels that are much better than the manual procedures in all respective. Although fire brigade is an excellent way out to control the fire but what if the team could not reach the accident area on time?
Here come the heat detectors, smoke detectors and flame detectors into play. These automatic systems are manufactured with LED lights or ionizing chambers, which are very sensitive in detecting any find of heat, smoke or fire.
The trend started with LED fitted smoke detectors or fire alarm systems. Whenever there is a fire, the smoke blocks the path of LED light and it triggers a bell. But sometimes, the technology fails when there is a fire or excess of heat but no smoke.
To serve the purpose, the ionizing fire alarm systems are much better. These are fitted with two separate plates charged negative and positive (to attract protons and electrons). In case of fire or heat, the electronically charges plates fait to attract electrons and the automatic fire alarm systems starts ringing the bell.
With advancements in technology, these automatic fire alarm systems or smoke detectors are being fitted with water sprinklers. It is an added advantage that whenever the fire alarm panel will ring in case of fire, the sprinkler will shower at the same place where the fire / heat / smoke is detected. This way, this hi-tech device also helps us to control the situation. Record reveal that the heavy implementation of these fire alarm systems and smoke detectors has resulted in a heavy fall of fire accidental cases.

Fundamental configuration of a fire alarm system
What is an automatic fire alarm system? An automatic fire alarm system is so designed that it is able to detect the unwanted fire presence by its monitoring of the changes in environment that are related to combustion. A fire alarm system can be actuated automatically or manually or in both ways. It is in event of fire that the automatic fire alarm system notifies persons to evacuate in the event of fire or in case of any other emergency. It also prepares the structure and its associated systems to control the spreading of the fire and the smoke.
Fundamental configuration of the fire alarm system
:
Fire alarm control panel: This component can be considered as the hub of the system. Its role is to monitor the inputs and the system integrity, to control the output and to relay the information.
Primary power supply: This is the alternating current which is non switched 120 or 240 volt that is supplied from a commercial power utility source. In non residential complexes a ‘dedicated branch circuit' is connected to the fire alarm system and its constituents.
Secondary or back up power supplies: This component is normally used to supply energy when a primary power failure occurs. It consists of sealed lead-acid storage batteries or other emergency sources such as generators.
Initiating devices: This component can be actuated manually or automatically. It acts as an input to the fire alarm control.
Notification appliances: The energy that is supplied from the fire alarm system or any other stored energy source is used by this component to inform the persons in the near vicinity to evacuate.
Building safety interfaces: This interface influences the air movement, the lighting, process control, human transport and the exit and thus permits the fire alarm system to control the various aspects of the built environment. It also prepares the building for the fire and controls the spread of smoke fumes and the fire.
