Traditional Crossbar Exit Device Design

The Arrow FS1805-RR-32D utilizes a traditional crossbar-style exit mechanism commonly specified for commercial and institutional buildings.

Unlike modern touch-bar panic devices with enclosed push rails, this design features a tubular crossbar supported by operating arms.

Depressing the horizontal crossbar activates the internal latch mechanism and releases the door for emergency egress.

Crossbar Features:

• Traditional commercial exit device configuration

• Full-width horizontal operating bar

• Mechanical rim latch release

• Durable metal operating components

• Convenient interior exit operation

• Designed for compatible commercial door preparations

• Architectural design suitable for matching existing installations

The traditional crossbar construction is particularly useful in renovation projects where maintaining a consistent hardware appearance is important.

Classroom Thumbpiece Function – ANSI 05

The FS1805 model designation identifies the Arrow Classroom-style thumbpiece function.

This function provides controlled exterior entry without restricting interior emergency exit operation.

Operating Functions:

Interior Exit Operation

Depressing the interior crossbar releases the rim latch and allows the door to open, regardless of whether the outside thumbpiece is locked.

Exterior Thumbpiece – Unlocked

When the exterior thumbpiece is unlocked by an authorized key, depressing the thumbpiece operates the latch and permits entry.

Exterior Thumbpiece – Locked

When the thumbpiece is locked, it cannot operate the latch from the exterior.

Key-Controlled Access

The key allows authorized personnel to change the exterior thumbpiece between locked and unlocked operation.

This configuration is commonly used where personnel need to control exterior entry while maintaining free interior egress.

Important: Confirm that the required thumbpiece trim and cylinder are included in the supplier's exact configuration before ordering.

Heavy-Duty Rim Latching System

The Arrow S1800 Series features a mechanical rim latching system designed to secure commercial doors using a single latch point.

The latch engages a compatible strike on the door frame or an approved mullion.

When the interior crossbar is depressed, the latch retracts, allowing occupants to exit.

Rim Latching Features:

• Single-point mechanical latching

• Surface-mounted rim configuration

• Stainless steel latchbolt

• 5/8" nominal latchbolt throw

• Mechanical crossbar operation

• Compatible commercial rim strike

• No surface vertical rods required

• Right-Hand Reverse configuration

This arrangement provides dependable mechanical operation while allowing convenient emergency exit.

Fire-Rated Performance & Life-Safety Applications

The Arrow FS1805-RR-32D is a fire exit hardware configuration intended for compatible labeled commercial door assemblies.

Fire exit hardware allows occupants to exit while maintaining positive latching when the door closes.

Fire Door Considerations:

• Suitable for approved fire-rated openings

• Positive mechanical latching required

• Compatible fire-rated rim strike required

• Door and frame must maintain applicable fire labels

• No mechanical dogging permitted in fire exit applications

• Installation must follow applicable manufacturer instructions

• Door handing must match the device configuration

• The complete assembly must comply with applicable fire and building codes

Important: The exact fire-rating duration and approved opening size for this model must be confirmed against its applicable listing before installation.

Heavy-Duty Commercial Construction

The Arrow S1800 Series incorporates durable materials and heavy-duty mechanical components for institutional and commercial use.

Construction Features:

• Pressure-formed non-ferrous alloy chassis

• Stainless steel chassis and end covers in the specified finish

• Forged metal crossbar operating arms

• Standard 1-3/4" door thickness

• Factory-specified Right-Hand Reverse handing

The durable construction is designed for repeated operation in commercial environments where dependable exit hardware is essential.

US32D Satin Stainless Steel Finish

The US32D Satin Stainless Steel finish, also identified as BHMA 630, offers a durable brushed-metal architectural appearance.

This finish is commonly specified in commercial buildings where stainless steel hardware is preferred.

Matching Hardware Applications:

• Stainless steel door closers

• Satin stainless steel push and pull plates

• Hollow metal commercial doors

• Stainless steel hinges

• Architectural kick plates

• Commercial locksets

• Stainless steel door stops

• Institutional door hardware

The satin finish offers a subdued appearance that coordinates with a wide range of commercial architectural hardware.

Product Specifications

Right-Hand Reverse Door Configuration

The RR designation identifies this device as a Right-Hand Reverse configuration.

Correct handing is essential because the exit device's latch mechanism and exterior operating hardware must match the door's swing direction.

Handing Considerations:

• Designed for Right-Hand Reverse applications

• Confirm the door's hinge location and swing

• Verify the latch engages the proper strike

• Match existing door mounting preparations

• Confirm exterior thumbpiece operation

• Verify door and frame compatibility

For a typical right-hand reverse door, the hinges are on the right when viewed from the exterior, and the door swings outward toward that viewer.
