Adams Rite 4089 Exit Indicator

4089 Exit Indicator provides exit door notification for various Adams Rite deadlocks.


Provides unmistakable notification of lock status. Under many local building safety codes this allows the use of a security deadlock instead of exit devices, in certain occupancies. 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.”. Please consult local Authority Having Jusidiction (AHJ) for more information.



Words “LOCKED" in red letters or “OPEN" in green letters appear on white background when bolt is thrown or retracted respectively. Indicator is driven by lock bolt itself.


Indicator escutcheon is zinc alloy. Available in choice of powder coat 119 to match 335 Black anodized, 121 to match 313 Dark bronze anodized, and 130 to match 628 Clear anodized. Header sign is clear aluminum match with black letters.
