Secure classrooms and high-traffic facilities with the Napco Security Technologies Trilogy DL3500CRL/26D high-security mortise classroom audit trail digital lock. Designed for institutional and commercial access control, this left-handed mortise lock delivers networked management via Ethernet or 802.11 and global lockdown capability—so you can centralize control and respond to incidents quickly. The DL3500 supports 300 user codes and records a detailed, time-stamped audit trail (day, date, time and user), giving you reliable monitoring and forensic data for investigations or compliance. Administrators gain scheduling flexibility with a real-time clock that enables up to 500 programmed lock/unlock events and holiday schedules, reducing manual tasks. Built for durability, the weather-resistant mortise mechanism, stainless latchbolt/deadbolt and satin chrome finish minimize maintenance while providing a professional appearance. The classroom function permits free egress from the interior for occupant safety while keeping the exterior secure.
