Operation
When the standby battery is connected to an RKI Instruments, Inc. controller such as the
Beacon 200, Beacon 410, or the Beacon 800, 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 controller and the level of
discharge, but a typical recharge time if the battery is completely discharged is about 4
days.
Runtime will vary depending on the controller and configuration of the controller. The
table below shows typical controller runtimes for common configurations.
