Function: Provides 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.”
Indicator: “OPEN” appears in black letters on white background when lock is retracted and “LOCKED” in red letters when actuated. Also available with red (locked) and green (unlocked) wordless panels.
Material/Finish: Indicator escutcheon is zinc alloy. Header sign is clear aluminum match with black letters.
Options: Standard unit fits 1-3/4″ doors.
