Alarm Lock Trilogy DL5200 - Electronic Double Sided Digital Locks

Alarm Lock's DL5200 series Electronic Double Sided Digital Locks come with a keypad in which users enter pin to unlock and open the door. The DL5200 series comes in two models, the DL5200 Standard Key Override and the DL5200IC Interchangeable Core.

These locks are grade 1, heavy duty, weatherproof locks, and can be used both in interior and exterior locations. The locks hold 100 user codes, and these user codes can be easily added, deleted or changed at the keypad itself. Programming codes on one side of the lock works on both sides, saving you time and labor.

In these double sided Trilogy locks, the secondary lock is a mirror image of the primary lock. The keypad on the secondary side matches the keypad on the primary side, improving lock aesthetics. Further, both sides of the locks even have the same cylinder.

Choose from a standard preparation or an interchangeable core model, which best suits your needs, when purchasing these locks.

Use the Alarm Lock DL5200 and/or the Alarm Lock DL5200IC as your door lock security solution in places such as community pool gates, courtyard gates, airport jet bridge doors, communicating doors, interrogation rooms, psych and Alzheimer areas etc.
