Customer Questions & Answers

  1. Q Does this lock come with the mortise assembly? answer now
    Asked by Nick on March 21, 2023 7:52 PM
    Answered by the admin

    Yes, this lock comes with the mortise assembly.

  2. Q Can this lock be used with a panic bar on the interior? answer now
    Asked by John on February 22, 2023 2:45 PM
    A

    This lock is not compatible with a panic bar exit, however the Trilogy ETDL is a similar lock that is compatible with a panic exit.

  3. Answered by the admin

    This model is not field reversible and needs to be specified to fit a right-handed or left-handed door prior to placing the order. 

  4. Answered by the admin

    Yes, this lock will accurately keep the Time and Date that is programmed into it and codes can be preenrolled to work during certain times or days. 

  5. A The model of the lock is determined by design. You can take a picture of the front of the lock and we will be able to tell you the model that you have. Please send the photo to [email protected] and they will be able to assist you.
  6. A

    No, you are able to program by hand if you wish, but it is not recommended for more than a few codes as the more you have the better it is to have a database backup should something go wrong. 

  7. A When the deadbolt is engaged it will not be retracted or unlocked by the keypad. The key from the key override must be used to open the door and retract the deadbolt from the keypad side of the door.
  8. A

    Yes, this lock does have the ability to be scheduled for auto unlock and relock of the door. You can set schedules either at the lock itself via the keypad or by purchasing the software for programming the lock. 

  9. A

    Should you be unable to change the batteries during the low battery warning stage for any reason you can only use the key override to gain entrance and then replace the batteries.
