Alarm Lock’s Trilogy 4100/4500 Features Privacy & Lock-Down
Amityville, NY – Alarm Lock Systems, Inc., has added privacy and residency features to Trilogy, the fastest growing line of electronic keyless pushbutton locks in the business. The 4100 and 4500 series in cylindrical and mortise lock styles are available in PIN or PIN/Prox models and can be used in any application large or small. 5AA battery-pak operates approximately 60,000 cycles typical. 1 3/8” mortise cylinder, ASA strike and standard door preps ensure that these locks will easily retrofit on all doors. Trilogy’s DL4100 and Prox PDL4100 come in 5 distinctly architectural finishes including US3 polished brass, 26 polished chrome, 26D satin chrome, 5 antique brass and 10B duronodic.

Similar to the PDL3000 but with the convenience of privacy and residency features, DL/PDL4100 and DL/PDL4500 are ideal for single occupancy restrooms, dressing rooms, darkrooms, hospital on-call sleeping rooms, executive offices, confidential file rooms and more. 2000 PIN or PIN/Prox user codes, 500 scheduled events, 40,000-audit trail make these locks a necessity for all those seeking the very best in security. With our latest weatherproof technology, both locks are able to withstand harsh weather conditions -31˚ to 151˚ F or (–35˚ to 66˚C). What’s more, end-users have the option to choose function models including right or left hand, classroom or deadbolt on the 4500 series mortise lock.

Trilogy’s DL4100 and PDL4100 privacy and residency options are unique features for added security. An occupied and multi-status LED indicator flashes when the privacy session is active. After entering a PIN or Prox ID, the user simply pushes the privacy button on the back of the lock (inner door). Doing so assures privacy, as the lock will not open from the front entry side, until the user exits (the door is reopened from the inside), or optionally, the privacy session “times-out” following a preset duration. A self-stick instructional sign will help guide users on how to activate and deactivate the privacy feature.

For residency applications, the residency feature can be an added benefit. This feature is programmable from the lock’s keypad. The residency feature allows users to exit their premises, closing the door behind them while the lock remains unlocked until it is physically relocked. This free-exit/passage mode is ideal for residents who may repeatedly find themselves unintentionally locked out without their Prox ID or PIN code, upon momentarily stepping out the front door to pick up their mail only to have the door accidentally lock behind them.
