4.8.6. Alerts and Multiple Monitoring Technologies

When multiple technologies are installed in a GuardII+, it is possible that each could have
a different Alert state.

• If any technology is in Alert, then the monitor is in the Alert state.
• If no technologies are in Alert, and at least one technology is in Stale Alert, then the
monitor is in the Stale Alert state.
• If no technologies are in Alert or Stale Alert, then the monitor is in the non-Alerted
state.
• An Alert Test state takes priority over all other Alert states.

4.8.7. Resetting an Alert

Once an Alert has occurred and any necessary actions taken as a result, there are two
methods that can be used to reset the GuardII+ Alert state.

• Press the Alert button as described in Section 6.5.1.
• Use IAM as described in Section 6.7.
NOTE:
Resetting the GuardII+ Alert state does not change the Alert settings
programmed into the monitor; if the settings are not changed and the
measurement results stay the same, then the Alert will occur again.
When the Alert is reset:

• The Alert indicators (on the panel and internal) revert to the non-Alert state.
• The Alert Relay will de-activate.

• The Alert Modbus data is updated.
