Guardian 715BBU Faq

Q: Can I use the GDO without installing the holster and/or the BBU?
A: Yes, but the GDO will not operate during a power outage.
Q: Can I set limits, add/remove remotes with the holster installed?
A: Yes, with the holster installed, the buttons for all the settings can still be accessed.
Q: Can I set limits, add/remove remote with the holster and BBU installed?
A: Yes, simply remove the BBU from the holster.
Q: Can I rework the wiring on the powerhead with the holster and BBU installed?
A: No, it is necessary to remove the holster to access wiring terminals.
Q: The BBU indicator does not glow when inserted into the holster.
A: Check for contact on the gold colored connectors on the battery and holder. Clean with alcohol wipes
if necessary and make sure there is a firm installation.
Q: Is it safe to keep the BBU on the holster always?
A: Yes, the system is equipped with smart battery management system to keep it well charged and
maintained. The battery status is always monitored.
Q: How long will it take to fully charge the BBU?
A: Appx. 8 hours from a fully drained state.
Q: How many door cycles can be achieved on BBU power only during a power outage?
A: Over 100-cycles can be achieved with a new battery, fully charged, at room temperature and balanced
8'x7' door, immediately after power has been cut. The battery will run for at least 10 cycles at
temperature extremes, in a 24-hr period.
Q: How long can the BBU keep its charge without re-charging?
A: The battery can keep its charge for 2~3 months. It's recommended to keep charging on the holster or
charged via external charging device at least once a month.
Q: How long will the BBU last?
A: Typically, it will last for 3-4 years with normal usage under normal environment.
Q: What is happening when the door is operating normally under AC power, but the operator
sounds 12 slow beeps when it almost reaches the UP limit during a power outage?
A: Since the travel speed during BBU mode is slower, with the reduced travel speed it may encounter low
speed/obstruction protection on the upmost soft travel. It will return to normal under AC power. If
necessary disable the soft travel mode and switch to the overdrive mode.
Q: Why doesn't the motion light turn on during door operation?
A: Under AC power, the motion light won't turn on with door operation. It only functions as a motion-
sensing night light. The LED motion light will turn on only during a power outage or when ambient light is
low. During a power outage the LED motion sensing light will activate with door operation and remain on
for 3 minutes.
Q: Why doesn't the motion light turn on with motion present when the door is open during the day?
A: The motion light will only turn on when motion is sensed and ambient light is low.
Q: Why does the motion light turn on when the car is moving?
A: The motion light detects heat and displacement; thus, heat pattern change will be sensed.
Q: Does the motion light work I take the BBU away from holster?
A: It will only work as motion-sensing night light under DC power.
Q: Can the motion light remain on for more than 3 minutes?
A: With continuous motion sensed, it will extend automatically. The light timer is independent of the 4.5-
minute courtesy light.
