Smoke Detectors versus Heat Detectors – What’s the difference?

A fire can break out anytime and it is a good thing to be prepared for any fire related emergency at all times. This is where smoke and heat detectors come into play. They are commonly used in buildings and work premises to protect people, property and assets.

Smoke Detectors

Smoke detectors are used to safeguard people as well as property by sounding an alarm much before a fire develops and spreads. A smoke detector is triggered when it detects the presence of soot in the air and warns of smoke in the area. Smoke detectors work on photoelectric and ionization technologies.

Even if a small amount of smoke is sensed, the smoke alarm is activated. Smoke detectors are quite sensitive and many times can even sound a false alarm. Smoke detectors are commonly installed in areas where smoky fires are most likely to occur.

Smoke detectors are usually more expensive than heat detectors; however, they respond to occurrence of a fire-related emergency earlier and give people enough time to react and take action before there is serious damage to property or life.

Heat Detectors

A heat detector is activated and sounds an alarm when it senses a change in the ambient temperature. The heat detector is triggered when there is a rise in temperature that is beyond a pre-set level. However, heat detectors cannot detect smoke. Heat detectors employ electro-pneumatic and thermocouple technologies for their working.

Heat detectors usually do not sound false alarms and only when the temperature is very high, an alarm is triggered. In case the temperature is not too high or there is only dense smoke, a heat detector will not be activated.

Heat detecting devices are typically used in places where high flames and intense heat can occur. Usually, heat detectors are fixed in places that are susceptible to fire breakouts; for example, in storage areas where fuels and combustible chemicals are kept.

Heat detectors are quite reliable when the main objective is protection of property. They are not very expensive to install and can withstand harsh environmental conditions as well as contaminants.

There are several differences between smoke and heat detectors. Both have their individual functions and the working principles of both devices are quite different. Smoke and heat detectors cannot be used interchangeably. This is why both these devices are installed in buildings and used in conjunction with each other and help to prevent damage due to smoke as well as fire.
