Red Alarm LED
Single blink if A1 condition is present.
Double blink if A2 condition is present.
If an alarm is configured acknowledge-
able and the alarm is acknowledged,
single/double blink changes into
continuous lit.
Alarm Hierarchy
A2 overrides A1 on the LED. However,
the
A1 and A2 relays operate
independently. I.e. if A1 is acknow-
ledgeable, A2 is not, and the gas
concentration is such that it triggers A1
and A2: acknowledging will cause the A1
relay to release. However, the red LED
will still double blink as long as the A2
condition continues to exist.
