SARGENT’s occupancy / status indicator option for the 8200 Series mortise lock provides security and safety at a glance with more functionality than previous versions. With the largest viewing window in the industry, a 180° visibility profile, reflective indicator materials and more color and text/graphic combinations to offer, the status indicator option ensures that the status indicator is clearly visible from a distance, providing assurance when you need it most.
These indicators are available with both sectional and escutcheon trims and are used in a variety of applications to identify occupancy or display locked/unlocked status of a room.
Furthermore, upgrading to the latest mortise lock status indicators is quick and easy for facilities with existing 8200 Series mortise locks. Upgrade kits use the existing door preparation and hide all pre-existing holes.
