Automatic Fire
Detection
Understanding the Risk

I n the event of a fire, delayed fire detection can
  lead to an increase in risk both to life and
property. An adequately designed, installed,
monitored and maintained automatic fire detection
system can help mitigate this risk by providing an
early fire warning, which will enable a timely
evacuation of the protected premises and the
prompt notification of the fire brigade.

A       ccording to statistics collated by the Fire
        Protection Association: -

      70% of all fires start between 6pm & 8am,
       when most premises are unoccupied.
      Over the period 1988 to 2008 total losses
       sustained from fires occurring between 6pm and
       8am exceeded £3b – these figures exclude the
       resultant business interruption losses.

and are not protected by an adequate automatic fire                                                    Typical automatic fire alarm panel
