Alarm Lock Trilogy 4100 (DL4100) Grade 1 Electronic Cylindrical Lock - Privacy Keypad

Professional Grade 1 Electronic Access Control with Privacy & Residency Features

The Alarm Lock Trilogy 4100 (DL4100) is a battery-operated electronic cylindrical lock built for commercial environments where privacy control and audit accountability matter. The all-metal 12-button keypad supports up to 2,000 user codes across four access levels - Master, Management, Supervisor, and basic user - and logs up to 40,000 timestamped events for compliance and security monitoring.

1) What applications is the Alarm Lock DL4100 series designed for?
The DL4100 series privacy cylindrical lock is designed for interior doors requiring privacy functions. Common applications include restrooms, offices, conference rooms, and other spaces where temporary privacy is needed with emergency access capability.

Standard cylindrical locks typically accommodate door thickness from 1-3/8" to 1-3/4". Verify your specific door thickness and check manufacturer specifications to ensure proper fit and function.
3) How do I determine the correct handing for this lock?
Stand on the side where the door opens toward you. If hinges are on the right, it's right-hand. If hinges are on the left, it's left-hand. Most cylindrical locks are reversible in the field by rotating internal components.
4) What finishes are available for the DL4100 series?
Alarm Lock typically offers multiple finish options including satin chrome, bright chrome, and oil-rubbed bronze. Verify available finishes for your specific model number as options may vary by series configuration.

6) Does the DL4100 require batteries or external power?
The DL4100 is a mechanical privacy lock that operates without batteries or external power. The locking mechanism is operated manually via the interior turn button or push button depending on the specific model configuration.
7) What is included with the DL4100 lock package?
Standard package typically includes the lock chassis, interior and exterior trim, latch assembly, strike plate, mounting screws, and installation template. Verify specific package contents as they may vary by model configuration and supplier.
8) What are the standard door preparation requirements?
Standard cylindrical lock preparation requires 2-1/8" cross bore, 1" edge bore, and 1-1/8" latch face mortise. Door edge must be square and properly reinforced. Use manufacturer's template for precise measurements and hole locations.
9) How do I adjust the latch backset on installation?
Most cylindrical locks offer 2-3/8" or 2-3/4" adjustable backset. Check the latch mechanism for adjustment tabs or rotating components. Measure from door edge to bore center to determine correct backset before final installation.
10) What related Alarm Lock models should I consider?
Consider other Alarm Lock cylindrical series for different functions. The DL3000 series offers passage function, while DL5000 series provides entrance/office function. Match the lock function to your specific access control needs.
11) How does the privacy function operate?
Privacy function allows locking from the interior side only. The exterior lever is disabled when locked, while the interior lever remains operational for egress. Emergency access is typically provided via small tool insertion in exterior trim.
