Interlock Switches:
Optional external interlock switches are required with some doors to prevent the door from operating under
certain conditions including the following:
• If the door is equipped with a functioning door lock, an interlock switch (A) must be installed to
prevent electric operation when the lock is engaged.
• If the door is equipped with a pedestrian pass-through door, an interlock switch (B) must be installed at
the pass-through door in order to prevent electrical operation when the pass-through door is open.
• If the door is equipped with a dock leveler the interlock circuit may be connected to the dock leveler to
prevent motor operation when the leveler is not in the down position.
