AA Battery
CAUTION
Batteries
Failure to change DEAD alkaline battery will eventually result in battery leakage,
causing permanent damage and loss of building control.
Failure to change a DEAD lithium battery will result in loss of trend and database if
not backed up, causing loss of data or building control.
Establish a preventative maintenance schedule based on expected battery usage and
life cycle.
● The AA battery maintains databases and volatile data, such as Trend, in RAM
when power to the controller is off.
● If reserve power in the AA battery is low, the battery status is reported as LOW or
DEAD and the red LOW BATT LED on the field panel is lit. When this occurs,
replace the battery; do not wait until it goes dead.
● Using PPCL and the $BATT point, the TC Modular can be programmed to signal
an alarm printer and an operator terminal with a battery replacement message.
For more information, see the TALON Powers Process Control Language (PPCL)
User's Manual (588-583).
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:
