Protect high-value entry points with the Napco Security Technologies DL3500DBL Trilogy high-security digital deadbolt — a commercial-grade electronic lockset engineered for demanding access control and physical security needs. Designed for left-handed doors in a Satin Chrome finish, this electronic deadbolt supports up to 2,000 user codes and stores a 40,000-event audit trail with time/date stamps, giving facilities managers and security professionals the visibility needed for effective monitoring and incident review. The DL3500DBL combines Grade 1 durability, a weatherproof build and a rugged clutch mechanism to minimize maintenance and ensure continuous operation in exterior or high-traffic interior locations. Multilevel security roles (master, manager, supervisor, basic user) simplify administration across retail, office, healthcare or industrial sites, while mechanical key override (Schlage C keyway) provides trusted backup access. Programming can be performed at the keypad or via PC/data-transfer for quick configuration and integration into existing security workflows. Ideal for perimeter doors, server rooms and controlled access areas where surveillance, auditability and reliability matter — contact sales to specify the DL3500DBL for your next access control upgrade.
