How do you test flame detectors?
– The portable flame sensor test unit should activate the flame detector at a distance of 3m within 20 seconds. – The detectors are fitted with internal IR LED’s that can be activated to optically test the detector. (The above tests apply to detectors at room temperature under normal factory lighting conditions.
How do I test my Fenwal heat detector?
Using a a heat gun, hair dryer, or similar heat source, apply heat evenly to the complete sensing shell. The heated air temperature must be above the alarm set point temperature of the unit. will either close or open which can be verified with a standard OHM meter. Remove the heat immediately after activation.
What is flame detector in ship?
Flame detectors are line of-sight devices that look for specific types of light (infrared, visible, ultraviolet) emitted by flames during combustion. When the detector recognizes this light from a fire, it sends a signal to activate an alarm.
Which sensor can detect fire?
Infrared thermal cameras MWIR infrared (IR) cameras can be used to detect heat and with particular algorithms can detect hot-spots within a scene as well as flames for both detection and prevention of fire and risks of fire.
How does flame detector work?
This type of flame detector works by detecting the UV radiation at the instant of ignition. Mostly all fires emit UV radiations, so in case of the flame, the sensor would detect it and creates a series of the pulse which is converted by detector electronics into an alarm output.
How does a Fenwal system work?
The Fenwal Continuous Fire Detection System stands alone in its field with the unique ability to detect specific overheat conditions at any point along the entire length of its sensing element run without regard for rate of temperature rise or average ambient temperature.
What is the range of flame sensor?
760 nm to 1100 nm
The IR flame sensor is used to detect the presence of fire or other infrared source (Flame or a light source of a wavelength in the range of 760 nm to 1100 nm can be detected)….Specifications.
