History software
Enables the DMP704 to store a one-line record of each event: e.g. alarms, restorals, and other operator events such as zone edits and in/out service actions. Memory capacity ranges from 4,000 to 16,000 events, depending on number of other options present in the system. Retrieval can be performed by zone, time and date, and type of event in any combination.
