    Asked by walter priddy on September 24, 2017 6:46 PM
    No, this is not something that is tested as it is not necessary for the install of this product. 
  4. A
    Yes, to both, however, this is only the locking portion of a system. There are several other items needed to make a whole system that will work. Please contact our sales staff so that they can make sure to get you the right products for your needs and for your specific door. 
  5. A
    When power is lost the magnetic lock will open as it is designed to fail safe. Normally we would recommend keeping the deadbolt, however we do understand code dictates keeping them or not. In order to overcome it you can add a backup battery to allow the battery to keep power cycled to the magnetic lock until the battery runs out. The second option would be to have a backup generator so you can continue to supply power. However, both are limited as the battery will eventually drain and the generator runs out of gas. You can refuel the generator and the batteries can be recharged if attached to another power source. Another option would be to add a keyless lock onto the door which would give you the option to still use a code or prox card to unlock the door and still keep the door secure until power is restored. Without knowing the type of door, two locks we recommend are the DL3200 and DL1300 (PIN only), or PDL1300 and PDL3000 (PIN + card).
