The Alarm Lock DL3500CR is designed for classroom security applications. It provides electronic access control with fail-safe operation during emergencies. The mortise lock fits standard commercial door preparations.
2) What door thickness does this lock work with?
This mortise lock typically fits doors from 1-3/4" to 2-1/4" thick. Verify your specific door thickness and weight capacity with the manufacturer template before installation.
3) How do I determine the correct handing?
Stand on the secure side of the door. If the door swings away from you and hinges are on the right, it's right-hand. If hinges are on the left, it's left-hand. Reverse for doors that swing toward you.
4) What finishes are available?
Alarm Lock typically offers finishes like satin chrome, dark bronze, and bright brass. Check the specific model configuration for available options. Finish should match existing hardware.
5) What power source does this lock require?
The DL3500CR operates on battery power with backup options. Check specifications for exact voltage requirements and battery life. Some models may require hardwired power connections.
6) How many user codes can be programmed?
Trilogy locks typically support multiple user codes with different access levels. Exact capacity varies by model. Codes can usually be added or deleted through the programming sequence.
7) What accessories are needed for installation?
Installation requires the lock body, strike plate, and mounting hardware included. You may need additional items like door reinforcement plates or custom strikes depending on your door frame.
8) Can this replace an existing mortise lock?
Yes, if your door has a standard mortise preparation. The lock fits ANSI/BHMA mortise cutouts. Verify the backset measurement and strike alignment before ordering.
9) How do I adjust the lock timing?
Lock timing is adjusted through the programming mode using specific button sequences. Consult the programming guide for your model. Timing affects how long the lock remains unlocked after code entry.
10) Are there similar Alarm Lock models available?
Yes, Alarm Lock offers other Trilogy models with different features and functions. Browse our Alarm Lock collection for comparable electronic mortise locks.
11) What door conditions affect performance?
Door alignment, frame condition, and proper strike adjustment all affect lock performance. Ensure the door closes flush and latches smoothly. Warped doors or loose frames can cause operational issues.
