49-8103RK Standby Battery • 8
Operation
When the standby battery is connected to an RKI Instruments, Inc. controller such as the
Beacon 110 (ordered with the optional battery charging capability) or the Beacon 200, the
controller maintains a trickle charge on the battery to keep it fully charged. If primary AC
power to the controller goes down, the standby battery will power the controller for a
limited amount of time until primary power returns. When primary AC power returns,
the controller will begin charging the standby battery. Recharge time will vary depending
on the level of discharge. A typical recharge time if the battery is completely discharged is
12 hours.
CAUTION: When using the standby battery with a Beacon 110, verify that the Beacon 110 was
ordered with the battery charging option. If the battery charging option is not
installed, the Beacon 110 will not charge the standby battery.
Runtime will vary depending on the controller and configuration of the controller. The
table below shows typical controller runtimes for common configurations.
