• Analysis of the flame flicker-frequency

for improved false alarm rejection

• Dual sensing methodology enables

a wide range of hydrocarbon and

non-hydrocarbon fires to be

effectively detected

• Good resistance against the influences of:

– Direct and reflected sunlight

– Artificial light, such as fluorescent tubes

and glass covered halogen lamps

– Arcs and electric discharges (static

or from e.g. electric motors)

– The radiation from electric welding

provided that the electric welding takes

place at a distance more than 10 feet from

the flame detector (a welding rod

contains organic compounds which

may produce a small flame)
