Alarm messages
The alarm messages are sent out at an interval of approx. 30 seconds, if no changes in
alarm state have occurred. If there are any changes in alarm state, a message
indicating the new state will be sent out immediately. If several alarms are active
simultaneously, a list with all messages will be sent out (Note that alarm messages and
VDR messages are mixed and appear randomly in relation to each other).
The system is able to report 3 different types of alarm: Output failure (lantern bulb
failure, cable break or other), power failure (one or more power supplies are out), and
communication failure (if the Master CPU do not get responses from modules or panel).
If there are no alarms present, the ‘No alarm’ message will be sent out.
