For Use with Model LDCO800
Garage Door Operators
PRODUCT DESCRIPTION
The Model BBU Battery Backup Unit is designed to provide DC power for Linear’s
Model LDCO800 Garage Door Operator during AC power outages.
The BBU contains two rechargeable batteries that are maintained and charged by
the LDCO800 operator. If the installation’s AC line power is interrupted, the BBU will
power the operator for up to 24 hours. The duration of the operator’s battery backup
will depend on the number of times the garage door is cycled without AC power. The
batteries will be fully recharged within 48 hours after AC power is restored.
The BBU contains an internal sounder to indicate the current status of the battery
unit. The unit regularly performs a self-check routine while AC power is present. If the
batteries test low or dead, the unit will sound three beeps every minute to indicate
that service is required.
Every LDCO800 is compatible with the BBU. The operator now has three pre-drilled
holes in the chassis to mount the BBU and a connector for the BBU on the controller
board.
For retrofi t installations, replace the LDCO800 operator’s controller board with a newer
Model HAE00061 controller board that has the BBU connector. Refer to the mounting
template supplied to drill three holes in the chassis of the operator to mount the BBU.
