FF703 Test Accessories
The FF703 is a microprocessor-based flame simulatorfor testing UV or IR or UV-IR flame detectors. Eliminates the need to use a flame. This unit is designed to generate a wide range of optical output signals, including several infrared channels to test dual infrared detectors. It can also emit a “blinking” infrared signal to test false alarms.
Flame detector features
Most optical flame sensors respond to ultraviolet (UV) or infrared (IR) radiation emitted by flames during combustion. Many sensors also use flame flickering techniques to distinguish between flames and other false optical sources.
The test unit simulates the flashing flame signal by modulating the output of a filament lamp. The thermal time constant of a filament lamp prevents the generation of a perfect flame flicker signal. The slow response of the filament lamp will mean that some flame sensors require more time to activate under test than they would with a real flame.
Who can operate this FF703 test accessory?
The unit is designed for use by service engineerswhen performing routine commissioning and maintenance. Because the test unit does not have an approval (Ex) for hazardous areas, a permit would be required to verify a detector in those areas. The service engineer couldalso carry a portable flammable gas alarm to indicate whether the area is safe for testing.
