Photoelectric smoke detectors are best for detecting ", The first primary type of heat detector is known as a, The second major type of heat detector is a. We'd love to hear from you in the comments! If a high-energy, high-heat fire occurs, the ambient temperature rises so quickly that the leak cant compensate for it and the air expands to the point where it pushes the diaphragm and activates a pressure switch in the sealed area which sounds the alarm. For more information, take a look at the FireGuard+ range of interconnectable detectors. Update Privacy Preferences At the end of the day, how we answer this question depends on the individual situation and on a combination of factors that have to be carefully analysed. Photoelectric smoke detectors are best for detecting "smoldering fires". On the other hand, heat detectors will not detect even the slightest amounts of a temperature change. Installing and maintaining smoke and carbon monoxide (CO) detectors can save your life. Phases of fire 4. Based on their targeted byproduct; a fire detector is of four types i.e smoke detector, heat detector, flame detector and combination of two or more.

This is the major advantage of smoke detectors over thermal detectors. Rate-of-rise compensated fixed-temperature detectors can help to prevent both thermal lag and false alarms due to rapid temperature changes. Alternately, the rate of rising heat might cause false alerts if the installation environment or your residential region naturally experiences sharp fluctuations in the ambient temperature. According to the National Fire Protection Association, there are an average of 358,000 residential fires each year, further spurred by broken heating equipment and electrical malfunction.
