Note that the second alarm is a high temperature alarm, and that it has an extra line in
its configuration, Delay after defrost. If a delay other than zero is entered, the high
temperature alarm will be disallowed following termination of defrost (provided
defrost is monitored).for the specified number of minutes. The time unit can not
changed. The time is always in minutes.
The key switch override is made functional by having a physical switch (usually
operated by a key to prevent inadvertent operation or tampering) and by having
configured a miscellaneous point for the switch, which is then wired to that point. The
logic written for the miscellaneous point will prevent alarms, after the switch is
operated, for the time specified as Delay after override. Such an override might be
used for case cleaning, extensive re-stocking, or service.

dialed out by the SC 255 when they occur. The alarm configuration screen for an
AKC 164 circuit looks like this:
