Highlights
1) The most basic difference between a heat detector and a smoke detector is that a heat detector senses changes in temperature while a smoke detector senses the presence of soot in the atmosphere.
2) Heat detectors utilize electro-pneumatic technology and thermocouple, while smoke detectors employ ionization and photoelectric technologies for their working principles.
3) Heat detectors are more reliable and do not give false alarms, while smoke detectors are notorious for sounding alarms even without real danger.
Introduction
Heat detectors and smoke detectors are both used in buildings to prevent fires. However, they have different functions and working principles. This article will explain the differences between the two types of detectors and why it is common to use them together.
Heat Detector vs Smoke Detector
The main difference between a heat detector and a smoke detector is how they sense danger. A heat detector senses changes in temperature and sounds an alarm when the temperature rises above a certain level. On the other hand, a smoke detector senses the presence of soot in the air and warns of smoke in the area.
Smoke detectors are known to be sensitive and can go off even with minimal smoke. That’s why they are usually installed away from kitchens, where smoke is common.
The working principles of heat detectors and smoke detectors also differ. Heat detectors use electro-pneumatic technology and thermocouples, while smoke detectors use ionization and photoelectric technologies.
Heat detectors are considered more reliable because they only give alarms when the temperature reaches dangerous levels. They do not sound alarms in the presence of smoke. On the other hand, smoke detectors do not sound alarms for temperature changes and are not designed to replace heat detectors. That’s why it is common to use both types of detectors together.
In places where fires are likely to occur, it is necessary to install heat detectors. Smoke detectors, on the other hand, are commonly found in places where smoking is prohibited.
In summary:
– Heat detectors sound alarms when they sense a sudden rise in temperature, while smoke detectors sound alarms when they detect any type of smoke.
– Heat detectors and smoke detectors are used together to protect against both fire and smoke.
– Heat detectors and smoke detectors have different working principles.
– Heat detectors are more reliable, as they only sound alarms when there is a real rise in temperature, while smoke detectors can have false alarms.
