What Types of Fire Alarm Systems Are Available Nowadays

Today, there are two basic kinds of fire alarm systems on the market, which are used and these are the automatic and manual types.

  • Both of these fire alarm systems can be coordinated to either safeguard lives only or to look after both lives and property.

 The automatic type can be used in either a conventional or computerised arrangement.

Automatic Set Up

The automatic fire alarm uses a linked up network of sensors that detect any of smoke and then set off an alarm. Both manual and automatic alarm systems can be utilised and set up to turn on sprinkler systems and also notify the local fire brigade.

Manual Set Up

The manual fire alarm relies on someone being present in a building who discovers the fire and then activates the alarm by hand. Devices referred to as “call points,” are found near doors and stairwells, so the alarm can easily be activated. As you must have seen somewhere, this type of fire alarm is usually seen in commercial or industrial buildings where nobody sleeps.

Safeguarding Lives and Containment

Various types of alarms have been designed in most cases to safeguard the lives of the occupants inside of a home or building. This type of fire alarm will go off when any fire has been detected, but may not turn on the sprinkler system or notify the fire brigade.

  • More complex systems will also shut down the ventilation system to prevent smoke and toxic fumes from spreading to other parts of a building.

Matters of Wiring

Wiring arrangement on automatic fire alarms is either conventional or computer assisted. In a normal configuration, buildings are split into two or more zones. Each zone has sensing devices connected to a control panel by way of an electrical cable.

The cable goes from the control panel to every sensing device in each zone. In this sort of conventional fire alarm setting, the activation of only one sensor will then activate alarms and sprinklers for the whole zone.

The Addressable System

Slightly different to conventional configurations, what is called an “addressable” system utilises an electrical cable that starts at the control panel, and then continues outwards to every sensor until a full circuit is completed and then returns to the panel. In this type of configuration, each individual sensing device is assigned an address.

  • If one individual sensor goes off, the control panel will activate alarms and sprinklers for just that one area based on the sensor’s address.

Alarm systems of this kind of configuration remove any need for a complete zone to be activated and allows for the fire brigade to know the exact location of the fire.

Fire alarms are definitely a vital part of all modern buildings best interests.
