The 4089-01-121 from Adams Rite is an Exit Indicator in Dark Bronze Anodized. The 4089 series exit indicator provides exit door notification for various Adams Rite deadlocks. It functions as providing an unmistakable notification of an exit door’s “locked” or “open” condition. Under many local building safety codes, this allows the use in certain occupancies of a security deadlock instead of less secure panic devices. It includes two permanent adhesive header signs: “THIS DOOR TO REMAIN UNLOCKED DURING BUSINESS HOURS.” (that wording is according to Uniform Building Code). The second sign for NFPA and other local codes reads: “THIS DOOR TO REMAIN UNLOCKED WHEN THE BUILDING IS OCCUPIED.”
