The Schlage 47858867 is the OEM indicator sign insert for the ND Series occupancy indicator lock family. It carries the "Vacant / Occupied" message and is the direct replacement component when the existing sign label is damaged, faded, or missing from a lock that was originally specified with outside or inside indicator trim. This is the part locksmiths and facilities teams order when the escutcheon and chassis are still serviceable but the indicator window label needs replacement.

The sign fits the full range of ND Series indicator lock models. If your building has a Schlage occupancy indicator lock and the message window is unreadable, this is the part to order before authorizing a full trim replacement.

Which Schlage ND Models Use the 47858867 Indicator Sign?

This indicator sign is used across eight ND Series lock functions. On the non-keyed side, it fits the ND40 IND OS Bath/Bedroom Privacy lock with outside indicator, the standard restroom privacy lock found throughout healthcare, hospitality, and office facilities. It also fits the ND44 IND OS Hospital Privacy lock with outside indicator, which uses a push-button locking mechanism with emergency turn-button override, purpose-built for clinical environments where staff need quick access capability.

On the keyed side, the 47858867 is compatible with the ND50 IND IS Entrance/Office lock with inside indicator, the ND52 IND OS Keyed Privacy lock with outside indicator, the ND53 IND IS Entrance lock with inside indicator, and the ND55 IND OS Entrance lock with automatic unlocking and outside indicator. It also covers both Vandilgard functions in the indicator family: the ND91 IND IS Vandlgard entrance/office lock and the ND92 IND IS Vandlgard entrance lock.

How the Schlage ND Series Occupancy Indicator System Works

The ND Series indicator trim uses a high-density polycarbonate viewing window mounted in an escutcheon-style trim plate. When the inside occupant engages the push button or turns the thumbturn, the mechanical linkage rotates the indicator sign behind that window to display "Occupied" on the exterior. When the door unlocks or closes, the sign returns to "Vacant." The 47858867 is the sign itself, the physical card that rotates behind the polycarbonate lens.

That viewing window spans the full width of the escutcheon at a height of 0.6 inches, which Schlage describes as unmatched visibility in the market. The indicator dimensions across the escutcheon are 3.66 inches wide with a 0.95 inch projection, and the window surface area runs 1.92 square inches compared to competitors that use much smaller indicator windows. The message is readable even from across a corridor, which is why the ND Series indicator trim gets specified for healthcare, K-12, higher education, government, and commercial office environments where staff need to confirm occupancy status at a glance without knocking.

What to Know Before Ordering

The indicator sign trim is designed for 1-3/4 inch standard door thickness. For doors between 1-3/8 and 1-11/16 inches, a separately sold spacer kit is required to take up the difference. Retrofit kits are also available for converting an existing non-indicator ND Series lock of the same function to an indicator configuration, so you don't have to replace the entire lock just to add occupancy indication to an opening.

The full ND Series indicator trim system is available in eight functions spanning two non-keyed privacy configurations and six keyed functions, including three with Vandylgard locked-lever protection. All indicator trim functions carry the same UL 10C fire rating as standard Grade 1 ND Series locks and comply with ANSI/BHMA A156.2 Series 4000 Grade 1, ICC A117.1 accessible facilities requirements, and the Buy American Act.
