19 ALARM
The alarms are divided into the following categories:
1. Signal only alarms (only a signal on the display, alarm relay)
2. Circuit alarms (they deactivate only the relative circuit, signal on the display, alarm relay)
3. Serious alarms (they deactivate all the system circuits, signal on the display, alarm relay)
4. Gas alarms (alarms related to the management of flammable gas)
The alarms must be considered as being manually reset, except for those specified otherwise.
