Alarm Lock Trilogy DL4100 Digital Keypad Privacy Lock

Privacy features: After entering with a PIN pass code the user pushes the privacy button on the back of the lock (inner door)

• 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)
