What are the types of fire detectors

Date of release:(2019-01-05)   Click times:658

Fire detector is an automatic fire alarm system, the scene of the investigation, found the fire equipment. The fire detector is the "sense organ" of the system, and its function is to monitor whether there is a fire in the environment. Once there is a fire, the characteristic physical quantity of the fire, such as temperature, smoke, gas and radiation light intensity, will be converted into an electrical signal, and immediately send an alarm signal to the fire alarm controller. Do you know the type of fire detector?


Smoke detector

Smoke fire detector is a response to combustion or pyrolysis produced by solid or liquid particles of the fire detector is the largest use of a fire detector. Some countries call smoke detectors "early detection" detectors because they can detect the concentration of aerosols or smoke particles produced in the initial stage of combustion.

The common smoke fire detectors are ion type, photoelectric type, inhalation type and so on.

The ion smoke detector is mainly composed of two ionization Chambers. The external ionization chamber (that is, the detection chamber) is connected with the outside world through a hole from which smoke can enter the sensor. The internal ionization chamber (or compensation chamber) is sealed so that smoke does not enter. When a fire breaks out, smoke particles will rush into the external ionization chamber, which interferes with the normal operation of charged particles, changes the current and voltage, and destroys the balance between the internal and external ionization chamber. The detector will generate induction and send out an alarm signal.

Photoelectric smoke detector with a light-emitting element and a photosensitive element, the common element by emitting light, shot through the lens on the photosensitive element, maintain normal circuits, such as smoke from blocking, arrived at the light on the light sensor will be significantly reduced, and photosensitive element is put the change of light intensity changes into current, by sending alarm signal amplifying circuit.


Suction type smoke detector change traditional smoke detector for smoke waft to passive detector for detecting way, but with new concept, namely active for air sampling detection, when reserve air samples were within the suction type smoke detector getter pump suction sampling pipelines, to the detector is analyzed, if it is found that the smoke particles, which issued a report to the police.

Today is a further understanding of the fire detector and its type, thank you for your browsing, there is more knowledge about the fire detector can be further concerned about the official website of xi 'an fan eram electronics co., LTD. http://www.xafiram.com
