3. General Application Information
3.1 Response Characteristics
Response is dependent on distance, type of fuel, temperature of the
fuel, and time required for the fire to come to equilibrium. As with all
fire tests, results must be interpreted according to an individual
application.
See Appendix A for fire test results
.
3.2 Important Application Considerations
In applying any type of sensing device as a fire detector, it is important
to know of any conditions that can prevent the device from responding
to fire, and also to know what other sources besides fire can cause
the device to respond.
3.2.1 Welding
Arc welding should not be performed within 40 feet (12m) of the very
high sensitivity detector (10 feet (3m) for medium sensitivity detector).
It is recommended that the system be bypassed during welding
operations in situations where the possibility of a false alarm cannot
be tolerated. Gas welding mandates system bypass, since the gas
torch is an actual fire. Arc welding rods can contain organic binder
materials in the flux that burn during the welding operation and are
detectable by the X33AF PL. Welding rods with clay binders do not
burn and will not be detected by the X33AF PL. However, system
bypass is always recommended, since the material being welded may
be contaminated with organic substances (paint, oil, etc.) that will burn
and possibly trigger the X33AF PL.
3.2.2 Artificial Lighting
The X33AF PL should not be located within 3 feet (1m) of artificial
lights. Excess heating of the detector could occur due to heat radiating
from the lights.
