Non- Addressable Fire Alarm Systems
Fire Alarm Systems (FAS) are an early warning system for industrial or residential complexes. A Fire Alarm System is a passive system, meaning it does not stop the fire from spreading. It means that the Fire Alarm System does not actively fight the fire. The main function of a Fire Alarm System is to give an early warning, that the fire has taken place in the factory or residential complex. This means that, the people in proximity to that area have an early warning to evacuate the building. However, the fire will continue to burn, unless if an active system like Fire Hydrant System or Fire Sprinkler System is engaged.
The second function of the Fire Alarm System is to, alert the responsible authorities. Here the authorities may be the local Fire Department or the Emergency Action team.The third function is to support the Fire Brigade, when they enter the building on fire. A Fire Alarm System also provides necessary emergency lighting, so that the Fire Team can navigate through the smoke and the dust. The Fire alarm system are designed as per NPFA 72, IS 15908 and NBC 2016 guidelines
