Alarm Hierarchy
A2 overrides A1 on the LED. However,
the A1 and A2 relays operate inde-
pendently. (Example: if A1 is acknowl-
edgeable, A2 is not, and the gas
concentration is such that it triggers A1
and A2: acknowledging the alarm will
cause the A1 relay to release. But the
red LED continues its double flash as
long as the state that triggers the A2
alarm persists.
