The ALM100 does not
sound when expected. Ensure that the ALM100 is properly connected and powered as
described in the preceding section. Use the “Test Annunciator”

receiving messages, as described in section 2.5.3.
Ensure that alerts are configured correctly. Ensure that the

appears in the list of annunciators to sound for the particular alarm.

Manual for details on alarm configuration.
