Relay 1 is pre-configured as the “Monitor Fail” alarm. This alarm activates is the monitor has a
hardware fault or if software becomes corrupted.

All other relays can be mapped to different alarm conditions. The monitor manual details how
these may be changed. On the standard Compact Systems alarms are preconfigured as
follows:

Relay 2: Summary Non-urgent alarm

Relay 3: Summary Urgent alarm

Relay 4: User Configurable

Relay 5: User Configurable

Relay 6: User Configurable

As mentioned, if these mappings are not appropriate, they can be changed in the field to suit
customer requirements.
