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.
