alarm condition exists, including system power failure. If NO is
chosen, the relay will allow activation of the alarms during alarm
status.
Note that an external alarm in series with a power supply should be
connected across the C and NC (normally closed) relay contacts in
fail-safe mode, and across the C and NO (normally open) contacts in
non-fail-safe mode.

in the Analyze mode menu must be pressed to end the alarm.
