Napco PDLN4100/26D Networx Cylindrical PIN / Prox Lock with Privacy Push Button on Inner Door

Protect entrances and simplify daily operations with the Napco Security Technologies PDLN4100 Networx cylindrical PIN/Prox electronic lock. Designed for commercial, multifamily and healthcare environments, this lock provides flexible credentialing—PIN, proximity card, or both—so you can match security to each door and user. With capacity for 2,000 user codes and a 40,000‑event audit trail, the PDLN4100 gives facility managers robust monitoring and reporting for compliance and incident review. The weatherproof satin‑chrome finish tolerates extremes from -31°F to 151°F, making it suitable for exterior doors, vestibules and high‑traffic interior entrances. Schedule access, holidays and automated actions with the real‑time clock (up to 500 scheduled events) and leverage the programmable Form C relay to integrate with CCTV, alarms or building management systems. The inner‑door privacy push button adds occupant convenience for restrooms and private offices while maintaining secure access from the public side.
