Alarm Lock will soon introduce an enhanced version of its Trilogy 4100 and 4500 privacy locks featuring an interior LED on the inside housing which indicates when the privacy session is active. A self-stick instructional sign helps guide customers on how to activate and deactivate the privacy feature. An occupied flashing multi-status LED indicator on the outside of our lock notifies users when the privacy session is active and the room is locked. Only after the user pushes the privacy button on the back of the inner door, will the door temporarily lock-out keypad codes. For information, call 1-800-252-5625 or visit www.alarmlock.com.
