e. High voltage condensers.
f. Radioisotopes.
Except under very unusual circumstances, none of these
sources, except a radiant surface or ignition spark, would be
present in or near the combustion chamber.
The detector may respond to a radiant surface at a
temperature above 2200°F (1200°C) if both of these
conditions are present:
• The detector sensitivity control is set at (or near) maximum,
