 Alarm Process
This is a function to activate a specifi ed alarm using contact input as a trigger.
To set an alarm for all GCMs, specify “0” for the “GCM number.” To set an alarm for each GCM,
specify the relevant GCM number.
The alarm level can be set to “2” or “3.” The alarm number is determined as follows depending on
the alarm level and the D/I contact number.
Alarm level 2: 200 + Contact number (No. 201 to 232)
Alarm level 3: 400 + Contact number (No. 401 to 232)
An alarm message can be defi ned using up to 22 alphanumeric characters.
For the details of alarms, see Section 7.1 “D/I Alarm.”
