Security Parts carries parts for all three Falcon exit device series. The 19 Series is narrow stile, light-to-medium duty, rim and SVR only. The 24 Series is narrow stile, heavy duty, for aluminum storefront doors with stiles as narrow as 1-3/4 inches. The 25 Series is wide stile, heavy duty, for standard hollow metal and wood commercial doors. The 24 and 25 Series share a push pad design and the same service manual (108004). The most frequently replaced parts are the channel, end cap kit, dogging cover plate, and on electrified versions, the EL solenoid or HWEA alarm board. For pre-June 2012 alarm assemblies, the HWEA replacement board is part 650335.

Falcon exit devices are on more commercial egress doors in North America than any other panic hardware brand outside Von Duprin. The 19, 24, and 25 Series cover the full range of commercial applications: from light office and retail doors through aluminum storefront entries to institutional hollow metal fire-rated assemblies. Each series has distinct construction, stile requirements, and electrified option sets. Getting the right replacement part requires knowing which series is installed and which sub-configuration applies.

Falcon 19 vs 24 vs 25 Series: Which One Is Installed

Before ordering any replacement part, identifying the series is mandatory. The three series look similar from a distance but are built for completely different door constructions. Ordering a 25 Series end cap for a 24 Series device, for example, produces a part that will not fit.

What Exit Device Configurations Mean for Parts Ordering

Each series offers multiple configurations that determine which latch hardware, rods, and strikes are involved. The configuration suffix on the model number tells you what is installed.

Why the Rim vs Vertical Rod Distinction Matters for Parts

A rim device has one latch point at the device head and uses a single rim strike on the door frame. A surface vertical rod device adds a bottom rod running from the device head to a floor bolt, creating two-point latching. The bottom rod, floor strike, and bottom latch components are additional parts unique to vertical rod configurations that rim devices do not use. If you are ordering a strike or latch bolt replacement, you need to know whether the installation is rim or VR before ordering.

The 25-V surface vertical rod uses a 3788 surface-applied top strike and a 2130 mortised bottom floor strike as the standard configuration. The 25-C concealed VR uses a 4188 mortised top strike and 2130 bottom standard, with 4155 and 2126A as bottom options. Fire-rated 25-C uses strike 1279 standard and F1280 for B label applications.

Falcon 19 Series Parts: Channels, End Caps and Key Components

The 19 Series uses a narrower channel profile than the 24 and 25 Series. All mounting screws are concealed; latch fasteners are exposed to the egress side. The push bar height is 1-3/4 inches. The stainless steel latch bolt has a 3/4-inch throw with deadlocking standard.

Falcon 24 Series Parts: Heavy Duty Narrow Stile

The 24 Series is built from extruded aluminum for maximum strength on narrow stile aluminum storefront doors. The construction provides greater impact resistance than the 19 Series at the same stile width. The push pad design is shared with the 25 Series, which is why both reference the same service manual 108004.

The 24 Series Door Thickness and End Cap Selection

The 24 Series serves aluminum storefront doors that come in two standard thicknesses: 1-3/4 inches (the most common commercial aluminum frame door) and 2-1/2 inches (thicker commercial storefront systems). The end cap kit part number changes based on this dimension. Part 650294 is for the 1-3/4-inch door and part 650348 is for the 2-1/2-inch door. Ordering the wrong kit produces an end cap that either leaves a gap at the stile edge or cannot seat against the door face at the correct depth.

Falcon 25 Series Parts: Wide Stile Heavy Duty

The 25 Series is Falcon's flagship exit device for standard commercial hollow metal and wood door applications. The center case is heavy wrought with sintered metal parts throughout the mechanism, making it more durable than extruded-only construction under heavy cycle loads. The top latchbolt is stainless steel with a 3/4-inch throw and deadlocking standard. Vertical rod configurations add a bottom bolt with a 1/2-inch throw.

25 Series Dogging: Half-Turn Hex, No Threads

Half-turn hex dogging is standard on the 25 Series with no threaded dogging components anywhere in the mechanism. Traditional threaded dogging on older exit devices requires turning a threaded rod several rotations, and the threads strip or corrode over time on high-cycle doors. The Falcon 25 Series half-turn hex design eliminates all threaded components from the dogging path. One half turn clockwise dogs the device. One half turn counterclockwise releases it. No stripping. No galling. This is why the 25 Series dogging mechanism outlasts competitor devices significantly on doors dogged and released multiple times daily.

Cylinder dogging is available as an option on the 25 Series using a 1-1/8-inch mortise cylinder with standard cam. This allows the outside cylinder to dog and release the device without carrying the hex key, which is the preferred configuration for reception desks and service counters where maintenance staff routinely dog the door at opening time.

25 Series Configurations and Stile Requirements

Stile requirements vary by 25 Series configuration. Standard 25-R and 25-V configurations require a 4-1/2-inch minimum stile. The 25-C concealed vertical rod configuration requires a 3-1/2-inch minimum stile on panic versions and 4-1/2-inch minimum on fire-rated F-25-C installations. The 25-CWDC (wood door wide cable configuration) requires a 6-1/2-inch minimum stile on wood doors. Ordering a 25-V or 25-C for a door with an undersized stile produces a device that cannot be correctly mounted.

25 Series Fire Ratings: A Label vs B Label

The Falcon 25 Series supports two UL fire ratings depending on the configuration. The B label (1-1/2 hour) is available on all 25 Series configurations. The A label (3-hour) is available on fire pairs (F-25-M x F-25-V or F-25-C), permitting up to 4-foot by 10-foot single doors and 8-foot by 10-foot pairs. When ordering strike replacements for fire-rated 25 Series installations, the fire strike specification matters. The F-25-C uses strike 1279 as standard and F1280 for B label applications. The F-25-V uses strike 299F for fire-rated top and 499F for fire-rated pairs with mullion.

Hex Dogging: How It Works and What Fails

Dogging is the function that holds the push bar depressed and the latch retracted, allowing the door to operate as a free-swinging door without requiring the push bar to be pressed on every pass. It is standard on the 24 and 25 Series panic versions and on the 19 Series panic version. It is never available on any fire-rated version of any series because holding a fire door latch retracted violates life safety code.

Hex dogging uses a hex key (Allen wrench) inserted into the dogging hole in the channel. On the Falcon 24 and 25 Series, the half-turn mechanism requires only a 180-degree rotation. The dogging cover plate conceals the dogging hole when not in use. This cover plate is a separately replaceable component if it is damaged or missing.

Electrified Options on the Falcon 24 and 25 Series

The Falcon 24 and 25 Series support a full range of electrified options for access control integration. Understanding the compatibility rules between these options prevents ordering combinations that cannot be installed together.

EL: Electric Latch Retraction

The EL option retracts the latch electrically without depressing the push bar, allowing the door to be opened from the outside by a credential reader, keypad, or building automation system. The EL solenoid operates at 24V DC and 0.34 amperes continuous duty. For 3-foot devices, the EL kit is part 650147. For 4-foot devices, it is part 650148. EL can be combined with FSA/FSE (fail safe/fail secure outside trim), DM (device monitoring), LM (latch monitoring), and AE/LK options. EL cannot be combined with ED (electric dogging), EA (exit alarm), HWEA (hard-wired exit alarm), or KOR (key override) on the same device.

Electric latch retraction serves two common use cases in commercial buildings. The first is controlled entry: a credential reader on the exterior side triggers the EL solenoid to retract the latch, allowing entry without pushing the panic bar. The second is electronic dogging during business hours: the building automation system energizes the EL solenoid for extended periods to hold the latch retracted as an alternative to mechanical hex dogging. This allows the door to operate in free-swing mode during hours and automatically re-latch when the solenoid is de-energized after hours.

EA and HWEA: Exit Alarm Options

The EA (exit alarm) option adds an audible alarm triggered when the push bar is pressed, providing delay notification or unauthorized egress alerting. The HWEA (hard-wired exit alarm) version connects to a building's wired fire alarm or security system.

The alarm circuit board replacement for pre-June 2012 HWEA assemblies is part 650335. This date boundary is critical: the alarm assembly design changed in June 2012. The 650335 board works only on pre-June 2012 assemblies. Post-June 2012 assemblies use a different alarm kit. Confirming the manufacturing date before ordering any alarm board replacement prevents a non-functional alarm installation.

KOR, LM, DM, RX: Monitoring and Override Options

KOR (key override) provides a cylinder that overrides the electrified outside trim functions without requiring electronic credentials. It is used when power failures need a mechanical fallback for authorized entry. LM (latch monitoring switch) monitors the latch bolt position and reports door open/closed status to the access control system. DM (device monitoring switch) monitors whether the push bar has been pressed. These two cannot be used on the same device because their switch mechanisms conflict. RX (request to exit switch) connects to an egress-side reader or motion sensor to signal the access control system that someone is approaching from the inside before the door opens.

How to Identify the Correct Part Before Ordering

Three pieces of information are needed before any Falcon exit device parts order.

1. Series (19, 24, or 25): Determined by the door construction and stile width as described above. The series number is typically visible on a label on the device channel or center case.

2. Configuration (R, V, C, CWDC, M): Visible from the door face. A rim device has a single latch point and no visible rod hardware on the door. A surface VR device has a visible bottom rod running down the door face to a floor strike. A concealed VR device has no visible rod hardware but two latch points (the concealed rods are inside the door stile).

3. Panic or fire-rated (prefix F-): Look for a fire label on the door or door frame. If a fire label is present, the device should be a fire-rated version. If ordering a replacement device, always match the fire rating of the original. If ordering a dogging cover plate, panic devices have a dogging hole; fire-rated devices do not.

Falcon vs Von Duprin: Choosing Between the Two Exit Device Brands

Both Falcon and Von Duprin are Allegion brands. They share company ownership but serve different market positions and use different part ecosystems. Parts are not interchangeable between the two brands.

Von Duprin is the older and more widely installed brand in institutional, healthcare, and high-security government applications. The Von Duprin 98/99 Series is the dominant exit device in North American institutional buildings constructed before 2000. Von Duprin has a larger installed base and a wider parts aftermarket. Browse the complete Von Duprin parts catalog for 98/99, 22, 33/35A, 55, 75, 78, 88, and 94/95 Series devices.

Falcon is more common in mid-market commercial, retail, multi-family, and newer construction where the architectural aesthetic of the flush push pad and concealed fasteners is valued alongside ANSI Grade 1 performance at a competitive price. The 24 and 25 Series were specifically designed for the streamlined appearance requirements of modern commercial construction.

On any given building, both brands may be present: Von Duprin on older egress stairwell doors that have not been replaced, Falcon on newer tenant improvement entries and interior egress paths. SecurityParts.com stocks both, so a single order can service the complete building hardware schedule.
