Fire alarm systems are equipped with an intricate design that is capable of detecting a fire quickly. Within a fire alarm, there is a heat sensor or detector that picks up the heat from a fire before it gets going, allowing people to get out of the area safely.
From Wikipedia, there are different types of heat sensors in various types of fire alarms, but basically a heat sensor responds and alarms “when the convected thermal energy of a fire increases the temperature of a heat sensitive element.”
The two main components of a heat sensor are thermal mass and conductivity of the element, which regulates the flow of heat into the element. Heat sensors operate as rate-of-rise and fixed temperature.
Heat sensors are an early warning sign against a fire. When this component is malfunctioning or not working at all, the lives of those occupying the space can be jeopardized. It is crucial that you always maintain your fire alarm system, which includes the heat sensor.
Signs that the heat sensor is not working can be as follows:
- Minutes have passed since the fire started and no alarm sounded
- A fire alarm is not working at all
If you notice either of the above happening or something else is not right with your fire alarm, it may be the heat sensor. In any event, it is always wise to have the fire alarm checked by a professional or to have the heat sensor replaced.
