Fire Alarm System In General

Fire alarm system is an important security device that helps to get protectecred ourselves from fire accidents. Nowadays fire alarm system became an essential one because of fire accidents. fire alarm system rises a loud sound and alerts , as soon as smoke is deducted by the smoke detector. In most cases fire alarm systems act at the instigation of fire detectors and other devices.

The Fire alert is of two types
      1. Fire alarm System
      2. Fire Suppression System

The Fire alarm is of two types
      1. Addressable Fire alarm System
      2. Conventional Fire Alarm System

Addressable Fire Alarm System

            This type of fire alarm system addressable fire panel is more advanced than a fire alarm system conventional panel. There are more programming options with these devices and as single point detection is an added option in this fire alarm system addressable pannel, it is easy to discover where an alarm device went off in the building using fire alarm system addressable fire panel and what alarm device is signalling a problem all those stuffs are shown in the display of fire alarm system addressable fire panel. An addressable fire alarm panel usually has loops and each loop corresponds with a number of alarm devices.The panel which shows the exact place of fire is called addressable fire alarm panel. In this fire alarm system addressable fire panel diffrent places are classified into loops. Per loop around 250 detectors are connected . Basic thing which are required In addressable fire alarm are addressable fire panel , addressable fire alarm smoke detector , fire alarm MCP (mannual Call Point ) , fire alarm Hooter ( sounder ). Important point is that the addressable detector will no support conventional panel and vice versa

Conventional Fire Alarm System

            Conventional fire alarm system fire panels have a small circuits connected to the device. The circuit covering the are a under protection are called as zone in the building in  Conventional fire alarm system. LED lights indicates if an area or zone in a building has been activated in the fire alarm system fire panels.The fire alarm device does not show the exact locatiom of fire. Conventional fire alarm panel shows only the approximate place of fire. Per zone 20 to 30 devices can be connected. Basic thing which are required In Conventional fire alarm are addressable fire panel , Conventional fire alarm smoke detector , Conventional fire alarm MCP (mannual Call Point ) ,Conventional fire alarm Hooter ( sounder ). Important point is that the Conventional detector will no support conventional panel and vice versa.

fire alarm system Control Units

The fire alarm system is controlled by a fire alarm control panel. Like any other security devices this fire alarm control panel can be referred as the head or brain of the fire alarm signal device. To priorly approximately how many fire alarm fire detector should operate shold be calculated. Besides this there are two more important units. The fire alarm signal that performs the main function and fire alarm pull station which transmits signals to the fire alarm through pull boxes.

Fire Alarm System Detectors

There are three types of fire alarm system detector

1.Fire alarm system smoke detector - when smoke comes , it senses it and then it sends to panel
2.Fire alarm system heat detector -when room temperature exceeds certain limt , it senses it and then it sends    to panel. It is used in kitchen ,pantry etc . where smoke is normally prevelant
3.Fire alarm system Photo detector - Whenever spark comes in the electrical cable the signal will be sent to panel

NOTE*- Multi sensor is also avilable which detecs all the above.
Ionization detector is banned in india.

Fire Alarm System Smoke Detectors

Fire alarm system Smoke detectors can further be divided into two categories namely Fire alarm ionization smoke detectors and Fire alarm photo electronic ionization units. A Fire alarm smoke detector will be helpful to deduct fire even before a fire catches. A Fire alarm smoke detector will therefore be able to help you in taking preventive actions at an early stage. Fire alarm Photo electronic ionization detectors can be used in houses while the other category can be used in offices. But the Photo electronic ionizationis banned in

Fire Alarm System Heat Detectors

Fire Alarm System heat detectors come in two types. They are known as fixed temperature and rate of rise Fire Alarm System heat detectors. In the first type the device will work if the room temperature reaches an optimal level of 45 °C or 60° C. However they can very well sense sudden and upward fluctuations of temperature. This device has a limitation when compared with smoke detectors because heat detectors can only recognize high levels of temperature and it is difficult to save property or people in most cases.This type Fire alarm system detectors are used in kitchen and in Ups rooms etc

Fire Alarm System Sounding devices

Alarm signal devices are of two categories namely audible and visual. The first one Emits loud noise and alerts you to escape from the fire outbreak. The loud noise may be in the form of bells or speakers or even sirens. Similarly visuals catch your attention by emitting certain types of lights like strobe light. It is also possible to intimate the fire service personnel through the sound.

Fire Suppression

incase of over all building height is more than 15m as per , National building Code it is compulsary to install sprinkler system

Sprinkler system

The sprinkler consist of a thin bulb with a liquid in it, it gets burst when the temperature xceeds 68 degree

Gas Based Fire Suppression

In order to protect the server room and data centres where the sprinkler system fails the gas based fire suppression is used
