1.2 Alarm States

Alarms have three states: occurred, recovered, and confirmed.
Alarm state
Occurred
Recovered
Confirmed
Example: When the source device address (the device address to monitor) is D100-0, the error state (when an alarm
has occurred) is ON, the channel is set to Unlock, and the used key button is CHECK
When the source device address is ON, the alarm changes to the "Occurred" state. When the source device
is OFF, the alarm changes to the "Recovered" state. When CHECK is pressed, the alarm changes to the
"Confirmed" state.
If CHECK is pressed before the source device address changes to OFF, the alarm changes to the "Confirmed"
state regardless of the state of the source device address.

First Alarm: The first alarm that occurs in a state where no alarms have occurred.
Second and later: An alarm that has occurred while another alarm is active.
Indicates that the alarm that occurred has been recovered from.
However, for channels set to lock, the alarm is not recovered from until a key button is pressed
(CHECK or All Chk.).
