Overview

The Cylindar Dogging Security Indicator (CDSI) / Hex Dogging Security Indicator (HDSI) provides at-a-glance verification of a door’s status from inside the room. Visible “LOCKED” and “UNLOCKED” indicators show whether the device is dogged or undogged. This feature can be used with hex key (HDSI) or cylinder (CDSI) options on various device types: rim, mortise or vertical systems.

Designed for high traffic institutional environments, such as schools and hospitals, the visual verification reduces the time to tour a facility and ensure that each door is secure with at-a-glance visual verification.
