Zeta - Model ZIS-FLD -Intrinsically Safe Flame Detector
The ZIS-FLD flame detector is designed for detection and signalisation of a flame ignition in case of a re hazard. The ZIS-FLD flame detector is intrinsically safe (IS) to be used in explosion hazard areas. It operates in detection lines connected to Zeta re alarm system control panels with an appropriate spark proof separator. The ZIS-FLD detector is designed for conventional use.
The ZIS-FLD flame detectors react to UV flame radiation with a wavelength of ~200 nm. The detectors are resistant to all sources of artificial light, which do not contain UV radiation. Ultra violet radiation falling on a gasfilled electron tube constituting an active surface
of the detector causes, as a result of photoemission phenomenon, an increase of the number of impulses counted by the measuring system. An electronic circuit of the detector transfers an alarm signal to the interoperating fire alarm control panel after counting a set
number of impulses. The active surface of the detector is made of quartz glass and its cleanliness should be maintained; touching it with
bare hands should be avoided.
