A rate-of-rise detector can detect a fire during the incipient stage when temperatures are rising rapidly. Different detection methods have varying sensitivities, with infrared radiation being important for heat transfer during fires.
A rate-of-rise detector can only detect a fire during the incipient stage. This stage marks the initial phase of a fire where temperatures are rising rapidly but flames have not yet developed.
The sensitivity of different detection methods varies; for example, a furnace has advantages over a flame in terms of sensitivity and sample size. The burner's adjustable stage allows for precise alignment for optimal detection.
Radiation, specifically infrared, plays a crucial role in transferring heat during a fire. Skin's sensitivity to this radiation allows individuals to sense a fire without direct visual contact.
