Using Auto Restore and Database Backup to Flash
● RAM is cleared if the AA battery is dead, disabled, or missing when power to the
field panel is off. In this case, if Auto Restore and Database Backup to Flash have
been enabled, the database reloads in RAM when power returns; however, Trend
data is lost.
● If a power failure lasts longer than the protection offered by the battery, and Auto
Restore and Database Backup to Flash are not enabled, the information stored in
RAM must be either reloaded from a TALON View workstation, Datamate Base or
Datamate Advanced, or entered again by an operator.
Coin Cell Battery
CAUTION
Batteries
Failure to change a DEAD lithium coin cell battery will result in loss of current time-
date, which may cause loss of data or building control.
Establish a preventative maintenance schedule based on expected battery usage and
life cycle.
● The coin cell battery maintains the current time-date in the Real Time Clock (RTC)
when power to the field panel is off.
● There is no physical status on the field panel for a dead coin cell battery.
● If the coin cell battery is dead or missing when power is off, then RTC time-date is
reset as follows:
– If the field panel resides on an ALN with a TALON View workstation, the
TALON View workstation sets the time-date when the field panel returns to the
network.
– If the field panel resides on an ALN without a TALON View workstation, the
time-date is synchronized with the network time during the next automatic daily
time update.
For more information on time synchronization, see the TALON Firmware User's
Manual (588-580) (588-580).
