Alarm Lock Trilogy DL4100 Digital Keypad Privacy Lock

The lock will now not open from the front entry side, until the user exits (door is reopened from the inside), or optional, the privacy session times-out following a preset duration During any privacy-session, the red LED on the outer, key-pad side of the door will flash to indicate that the room is occupied When exiting the room, the occupant simply leaves normally As an added safeguard, this exit sequence, triggered by the rotation of the inside handle will also enable a 3 second delay, before it will accept an additional signal from the privacy button (eliminating inadvertent privacy-locking)
