The Alarm Lock Trilogy Cylindrical Pin Lock is an electric keypad with advanced features that are programmable by fingertip on the device or through a PC. As Alarm Lock's most popular model, you can choose from weatherproof, audit trail, and privacy features. It provides up to 2,000 user codes with a variety of security settings. A timed egress feature is included that allows the door to hold open for 5, 10, or 15 seconds and has a remote release feature. As a Trilogy product, there is a global lockdown feature that eliminates door-to-door programming and audit trail queries by communicating wirelessly via ethernet. This keypad is ideal for use with 12V or 24V(AC or DC) electric door strikes, mag lock, or Alarm Lock Remote Release Kit. The DK3000 is not a complete lock system. Instead, it should be thought of as a lock controlling device that is able to activate or deactivate a door strike or magnet locking device. The 2800, 3000, and 3200 series locks come with an audit trail that can track detailed information such as time stamps, users, and automatic lock/unlock events to the most recent 40,000 actions.
