What is a combination smoke heat detector?

Fire Detector It is a device for detecting fires in the automatic fire alarm system for fire detection. The main classifications are smoke detectors, heat detectors, and combinationsmoke heat detectors.

The temperature-sensitive fire detector uses the sensitivity of the thermal element to the temperature to detect the ambient temperature. It has a built-in single-chip microcomputer to cure the highly reliable fire judgment program and uses a special process to handle it.

The smoke detector uses infrared scattering technology and uses imported optoelectronic devices to improve the reliability, stability and consistency of the sensor. It also prevent insects, dust and external light. The product has a novel structure, beautiful appearance, stable and reliable performance, strong moisture resistance, and good chemical resistance.

The combination smoke heat detector is the combination of the above heat and smoke detector, and it perfectly uses the composite detection technology that is a new type of multifunctional and highly reliable fire detection technology popular in the world today. It not only has the performance of ordinary photoinductor smoke fire detector, but also has the performance of constant temperature and differential constant temperature fire detector. At the same time, the smoke heat detectorcan also detect and fire open flames with obvious temperature rise, such as alcohol combustion, which expands the application range of photoelectric smoke detectors.

fire detector heat alarm FAQ

What does a fire detector heat alarm do?
A detector heat alarm is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. ... All heat detectors have this thermal lag. In addition, Heat detectors have two main classifications of operation, "rate-of-rise" and "fixed temperature".

What is the difference between a heat detector alarm and a smoke detector?
The smoke detectors use ionization and photoelectric technologies whereas a detector heat alarm uses thermocouple and electro-pneumatic technologies. While the smoke detectors are very sensitive and are prone to give off false alarms. The heat detectors are more reliable fire detectors, even in dusty environments. so we suggest installing fire detector heat alarm in the right place.

How long does a fire detector heat alarm last?
the answer is, if heat increases rapidly or the temperature reaches the fixed threshold. Heat detectors do need to eventually be replaced, though. Normally, heat detector alarms can last up to ten years whenever operating.

Where can you use a fire detector heat alarm?
A heat detector is usually used in rooms where there is excessive dust or fumes – for instance, a garage or cellar – which a smoke alarm can mistake for dust, soot or combustible elements in the atmosphere. SO, fire detector heat alarm is more suitable for used in rooms where there is excessive dust or fumes rather than smoke detectors.Meantime, the detector heat alarm is also used in rooms where highly-flammable chemicals are stored.
