Drop-Bar Exit Device Design

The Arrow FS1805-LR-32D incorporates a traditional drop-bar style exit mechanism intended for commercial doors where mechanical reliability and dependable emergency egress are essential.

The device operates from the interior by actuating the exit bar, which releases the rim latch mechanism and permits the door to open.

• Rim-style latch engagement

• Suitable for appropriately prepared commercial doors

• Compatible with designated exterior thumbpiece operation

• Practical for renovations and replacement installations

• Designed for reliable commercial door operation

This configuration is particularly useful when replacing existing Arrow exit hardware while maintaining a consistent hardware style.

Thumbpiece Function – Key-Controlled Exterior Entry

The FS1805 designation identifies a thumbpiece-operated exterior entry function.

This configuration allows authorized users to control whether the exterior thumbpiece operates the latch.

Operating Functions:

• Interior Egress: The exit bar releases the latch for emergency exit.

• Exterior Thumbpiece Unlocked: The thumbpiece can operate the latch to permit entry.

• Exterior Thumbpiece Locked: Exterior thumbpiece operation is disabled.

• Key Control: A compatible key-operated cylinder controls the locked or unlocked state of the exterior thumbpiece.

The thumbpiece function is suited to commercial openings where building personnel need controlled exterior access without restricting interior emergency egress.

Important: Verify the supplied exterior thumbpiece trim, cylinder, and keying configuration before ordering.

Fire-Rated Door Performance

The Arrow FS1805-LR-32D is identified as fire-rated rim exit hardware.

Fire exit hardware is designed to permit emergency egress while maintaining positive latching when the door is closed.

Fire Door Considerations:

• Intended for properly labeled fire door assemblies

• Compatible fire-rated frame and strike required

• Positive latching must be maintained

• Mechanical dogging must not defeat required fire-door latching

• Installation must follow the applicable manufacturer listing

• Door handing and hardware preparations must match the device

• The complete opening must meet applicable fire and building codes

The fire rating of the complete door assembly depends on the approved door, frame, exit device, strike, and installation.

US32D Satin Stainless Steel Finish

The 32D / US32D Satin Stainless Steel finish, also identified as BHMA 630, provides a professional appearance commonly specified in commercial architectural hardware.

The satin finish offers a subdued, brushed-metal appearance that complements:

• Stainless steel door closers

• Stainless steel push and pull plates

• Hollow metal commercial doors

• Stainless steel architectural hardware

• Commercial door hinges

• Stainless steel kick plates

• Healthcare and institutional door hardware

Satin stainless steel is especially popular in commercial environments where a consistent architectural hardware finish is required.
