Can I mute the beeping sound made by the garage door operator when closing?

No. The beeping sound from the garage door operator is an alert for persons near the garage door to stay away from the garage door while it closes. This safety standard is required by UL 325 for unattended control of a garage door. The beeping cannot be turned off and its volume cannot be controlled.

UL 325 was revised in 2009 allowing unattended operation features.

Several key provisions must be met for such operation:

  • The feature must be utilized only on an operator equipped with a secondary entrapment protection system such as a photoelectric sensor.
  • The feature must be activated only when the operator is installed on a sectional door.
  • The operator must be equipped with an audible and visual warning system indicating a pending motion for five seconds before the door starts moving.
