Every 83 seconds a fire stats, and in some cases lives are taken. So
every one should know how serious a smoke detector or smoke
alarm is. They sense the first sign of flame, give the earliest alarm
so people can survive by getting the most precious in a fire incident-
the time to run.
Most smoke detector fall into two types - inolization type and
photoeletronic type. Inolization alarm has edge in sensing small
particles of smoke produced by flaming fires, such as chip pans, and
will detect this type of fire before the smoke gets too thick.
The laser one is more expensive but more effective at detecting larger
particles of smoke produced by slow-burning fires, such as smouldering
foam-filled upholstery and overheated PVC wiring.
To have doubled safety, a dual sense alarm seems the right way however
they are quite expensive.
