About the Real-Time Clock
All schedules (permanent, temporary, holiday, and ambush) are based on the time and date from an
internal real-time clock. Also, the history log uses the time and date when events are logged. During
system installation, the clock should be initially set to the time (hour and minute) and date (month,
day, and year).
If the system loses all power or is powered down for any reason, the clock must be reset. The clock does not
advance during the time the system does not have power connected.
