Heavy-Duty Grade 1 Commercial Fire Exit Hardware with Key-Controlled Exterior Thumbpiece

The Arrow FS1805-RR-3 Fire-Rated Rim Exit Device is a heavy-duty commercial exit device designed to provide reliable emergency egress, secure mechanical latching, and controlled exterior access for commercial and institutional door openings.

Part of the Arrow S1800 Series, this fire-rated exit device features a traditional crossbar (drop-bar) operating mechanism, a surface-mounted rim latch, and a key-controlled thumbpiece function that allows authorized personnel to lock or unlock exterior thumbpiece operation.

Finished in US3 (605) Bright Brass, the FS1805-RR-3 offers a polished architectural appearance that coordinates with traditional commercial door hardware, brass-finished hinges, locksets, and other decorative building hardware.

This model is specifically configured for Right-Hand Reverse (RHR) door applications and is designed for compatible fire-rated commercial openings.

The Arrow S1800 Series is identified in manufacturer literature as ANSI/BHMA A156.3 Grade 1 commercial exit hardware, offering dependable mechanical operation for high-traffic facilities.

Traditional Crossbar Exit Device Design

The Arrow FS1805-RR-3 incorporates a traditional crossbar-style exit mechanism designed for commercial buildings where dependable mechanical operation and a classic architectural appearance are required.

Unlike modern enclosed touch-bar exit devices, the Arrow S1800 features a tubular crossbar supported by operating arms.

Depressing the horizontal crossbar activates the internal rim latch mechanism, allowing the door to open for emergency egress.

Crossbar Features:

• Traditional commercial exit hardware design

• Horizontal tubular operating bar

• Mechanical rim latch release

• Heavy-duty metal operating arms

• Interior push-to-exit operation

• Surface-mounted hardware configuration

• Suitable for compatible existing door preparations

• Architectural design appropriate for replacement and renovation projects

This design is particularly useful when maintaining a consistent hardware appearance throughout a commercial building.

Classroom Thumbpiece Function – ANSI 05

The FS1805 designation identifies a Classroom-style thumbpiece function.

This configuration allows authorized personnel to control exterior entry while maintaining unrestricted emergency exit from the interior.

Interior Exit Operation

Depressing the interior crossbar releases the rim latch, allowing occupants to exit whether the exterior thumbpiece is locked or unlocked.

Exterior Thumbpiece – Unlocked

When unlocked using the appropriate key, the exterior thumbpiece can operate the latch to permit entry.

Exterior Thumbpiece – Locked

When locked, the exterior thumbpiece cannot retract the latch, preventing normal entry through the outside trim.

Key-Controlled Access

A compatible lock cylinder allows authorized personnel to change the exterior thumbpiece between locked and unlocked operation.

This function is commonly specified for commercial openings where access must be controlled without restricting emergency egress.

Heavy-Duty Rim Latching System

The Arrow S1800 Series utilizes a single-point rim latching mechanism that engages a compatible strike mounted to the door frame or approved mullion.

Unlike surface vertical rod exit devices, which use top and bottom latches, this configuration uses a single latch positioned along the lock edge.

Rim Latching Features:

• Single-point mechanical latching

• Surface-mounted rim configuration

• Stainless steel latchbolt

• 5/8" nominal latchbolt throw

• Heavy-duty mechanical crossbar operation

• Compatible rim strike required

• No vertical rods

• Right-Hand Reverse configuration

This arrangement provides secure door operation while allowing convenient emergency exit.

Fire-Rated Performance & Life Safety

The Arrow FS1805-RR-3 is identified as fire-rated rim exit hardware intended for compatible labeled commercial door assemblies.

Fire exit hardware must provide reliable interior egress while maintaining positive latching when the door closes.

Fire Door Considerations:

• Approved fire-rated door and frame assembly required

• Compatible fire-rated strike required

• Positive mechanical latching must be maintained

• Mechanical dogging must not defeat required fire-door latching

• Manufacturer installation instructions must be followed

• Proper door handing and hardware preparation required

• Complete opening must meet applicable building and fire codes

The exact fire-rating duration and maximum approved opening dimensions must be confirmed for the specific installation.

Heavy-Duty Commercial Construction

The Arrow S1800 Series features durable mechanical components designed for repeated commercial operation.

Construction Features:

• Pressure-formed non-ferrous alloy chassis

• Metal chassis and end covers

• Heavy-duty forged crossbar operating arms

• Tubular metal crossbar

• Stainless steel rim latchbolt

• 5/8" latchbolt throw

• Standard 1-3/4" commercial door thickness

• Factory-specified Right-Hand Reverse handing

• Bright Brass US3 architectural finish

The rugged mechanical design makes this device suitable for commercial environments requiring dependable exit functionality.

Bright Brass Finish – US3 / 605

The US3 Bright Brass finish, also identified as BHMA 605, provides a polished golden-brass appearance.

This traditional architectural finish is commonly specified in buildings where brass-finished commercial door hardware is used.

Matching Hardware Applications:

• Bright brass commercial locksets

• Polished brass door hinges

• Brass push and pull plates

• Architectural kick plates

• Brass-finished door stops

• Commercial building entrance hardware

• Traditional institutional door hardware

The Bright Brass finish is an excellent option for renovations and replacement installations requiring matching architectural hardware.

Product Specifications

Right-Hand Reverse Door Configuration

The RR designation identifies the device as a Right-Hand Reverse (RHR) configuration.

Correct handing is essential because the latch mechanism and exterior thumbpiece must match the door's swing and hardware preparation.

Handing Requirements:

• Right-Hand Reverse configuration

• Outward-swinging door application

• Verify hinge location and swing direction

• Confirm proper latch engagement

• Check exterior thumbpiece placement

• Match existing door hardware preparations

When viewed from the exterior, a typical RHR door has its hinges on the right and swings toward the viewer.

Recommended Commercial Applications
