Smoke Vs Heat Detectors

When it comes to protecting your workers, it is critical to warn them of any hazards or dangers at the earliest opportunity. In the case of an emergency, a smoke or heat detector is crucial to alarm workers before smoke accumulates.

But there can often be some confusion between whether or not a business should have a smoke or heat detector, as there are several differences between them. However, when in installed in buildings and used in conjunction with each other, they can help prevent smoke and fire damage.

Here at Bull, our ambition is to ensure buildings and sites have all the correct fire equipment. Our smoke and heat detectors have been designed to protect workers, and ensure people are made aware of the emergency so they can act swiftly. So, what are the differences between smoke and heat detectors?

Smoke detectors


Intended to protect people and safeguard properties, smoke detectors work by generating an alarm before the spread of a fire.

A smoke detector is triggered when it detects the presence of soot in the air and warns of smoke in the area. They are most likely installed in areas where smoky fires are likely to occur.

In addition to giving workers more time to react, advanced smoke detectors often allow first responders to address the fire hazard before serious property damage occurs.

Heat detectors


Heat detectors are intended to minimise property damage by reacting to the change in temperature caused by a fire.

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.

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. In other cases, the heat detectors are used to trigger fire sprinklers or other types of fire suppression systems.

Heat detectors usually do not sound false alarms, and an alarm is triggered only when the temperature is very high. They cannot detect smoke as they do not sense particles of combustion, and are designed to only alarm when heat on the sensors increase at a predetermined rate.

In some cases, heat detectors are chosen because of their low cost and greater immunity to contaminants and environmental extremes.
