Major/Minor Alarm Relays
When programmed as a minor or major alarm indication, the relay operates if the
system fails to pass a diagnostic test. This test falls under the corresponding alarm
category. The relay is released when the relay dial access code is dialed or when a
subsequent execution of the diagnostic test that is issued the alarm is successfully
passed.
