What might be the more difficult aspect (possibly) would be the
continuity detection (wirelessly), as we would need to have the
circuitry in the range-head box to 'tell' the wireless unit if
continuity was present, etc. And this circuitry would need to work
in conjunction with the current system of the push-button/buzzer for
the pad area itself. We'd also need to ensure that we can handle the
wider-range of igniter firing levels (like the new Quest igniters)
with such a system..
Speaking of which ---
Has anyone ever come up with a chart of all-fire/no-fire levels for
all igniters? And determined a range that might be guaranteed to work
for those (with inclusion for wire lead resistances, etc.)?
