LDCO800 Garage Door Opener
MODEL BBU BATTERY BACKUP UNIT
User’s Guide
Your Model LDCO800 Garage Door Opener is specially
equipped with Linear’s Model BBU Battery Backup Unit.
In the case of an AC power failure, the Battery Backup Unit
will power your garage door opener for up to 24 hours without
AC power. The length of time that the Battery Backup Unit
will power the opener depends on the number of open/close
cycles performed while the opener is on battery backup power.
Note that the opener’s courtesy lamp will not light while the
opener is operating on battery backup power.
When the AC power returns, the Battery Backup Unit will
automatically charge its batteries. Allow 48 hours for a
complete battery recharge.
The Backup Battery Unit regularly performs a self-check
routine. If the self-check detects that the batteries are no
longer serviceable, the three beeps will sound from inside
the opener every minute. If this occurs, call your garage door
installation professional for a replacement Battery Backup Unit.
