Important note for Relay Voting
A channel set to channel disarm presents as a persistent Normal state as does a
channel in Normal state at the time of a slot level disarm.
Consequently any “N out of N” logic utilizing this channel will never trigger the relay and
“n out of N” will only trigger in a reduced set of circumstances.
General rule for n out of N: if at least [1 + N
–
n] channels are disarmed the relay will
never activate.
