what is the slowest acting fire alarm type
heat detectors
what does spot type mean in relation to fire detecting systems
they are desinged to detect heat only in a relaitivly small area around the detector

they detect heat over a linear area parallel to the detctor
how does IR detctors respond to sunlight
they go off, ultraviolet are better 2 use when there is going to be sunlight
