UVIR Flame Detectors
Monitors higher hydrocarbons flames (wood, paper, petrol) but also hydrogen and lower hydrocarbons such as methanol and methane.
Good resistance against the influences of:
direct and reflected sun light.
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 3 meters from the flame detector (a welding rod contains organic compounds which show flame phenomena).
Less suitable for very smoky fires. This inhibitor of both the UV-sensor and the IR-sensor affects the flame detector performance.
Automatic Sensor Test (Built-in Self-Test) which monitors the sensors and the electronics of the flame detector for its proper operation.
DIP-switches to set the sensitivity and latching/non-latching alarm relay outputs to adjust the flame detector to the application (not active in EN54-10 models).
