The Von Duprin 6100 is a heavy-duty, stainless steel electric strike built specifically for rim exit device applications. It is fire rated to UL10C, carries UL1034 burglary-resistant listing, and meets ANSI/BHMA Grade 1 with a 1,500 lb hold force. When a 6100 stops releasing correctly, the replacement path is a box assembly - the entire internal electromechanical unit that controls the keeper. Thirty OEM box assemblies are stocked at SecurityParts.com, organized by fail mode, voltage, and application. This guide covers every Von Duprin 6100 electric strike parts selection decision you need to make before placing an order.

For replacement parts across all Von Duprin electric strike series, including the 5100, 6200, and 6300, see the Von Duprin electric strike parts guide. This article is the dedicated 6100 resource.

Quick Answer

• The Von Duprin 6100 is a rim exit device electric strike only. It is not compatible with cylindrical locks or mortise locks. Confirm the installed hardware is a rim exit device before ordering any 6100 part.
• The primary replaceable component is the box assembly. The 6100 uses internally contained box assemblies that differ by fail mode (fail safe or fail secure), voltage (12VDC, 24VDC, or AC-compatible), and application (standard, dual switch, or specific function variants).
• The 6100 is fire rated. UL10C listing covers up to 3 hours on single doors and 90 minutes on pair doors. Fail-secure configurations are available for fire-rated openings. Fail-safe configurations are non-fire-rated.
• The 6100 ships standard as 24VDC fail secure. Confirm the installed voltage and fail mode from the existing device before ordering a replacement box assembly.
• Browse all 30 available OEM parts at the 6100 series parts catalog at SecurityParts.com.

What Is the Von Duprin 6100 Electric Strike?

The Von Duprin 6100 is a heavy-duty rim electric strike designed for commercial and institutional openings where the primary hardware is a rim exit device. It is the standard specification for rim exit device openings requiring electric strike access control in high-traffic, high-security, or fire-rated applications.

Three product characteristics define the 6100 and distinguish it from other Von Duprin electric strike series:

Rim Exit Device Compatibility Only

The 6100 interfaces with the rim exit device latch mechanism via a movable keeper. It is not designed for cylindrical locks, mortise locks, or deadlatches. If the hardware is a cylindrical lock, specify the 5100 or 6200. If a mortise lock, specify the 6200.

Compatible rim exit device families include Von Duprin and Falcon rim series devices. The 6100 also supports retrofit with many legacy rim nightlatch applications.

Fire-Rated Construction

The 6100 carries UL10C fire listing, covering up to 3 hours on single doors and 90 minutes on paired doors. This is a critical distinction from the 5100, which has zero fire rating. If the door assembly carries a fire rating and electric strike access control is specified, the 6100 is the appropriate choice. For fire door hardware compliance requirements and what listings apply to specific assemblies, see the commercial door fire rating guide.

Heavy-Duty Stainless Steel Construction

The 6100 body is stainless steel construction rated for heavy institutional use. UL1034 burglary-resistant listing and ANSI/BHMA Grade 1 certification at 1,500 lb hold force are standard across all 6100 models. Two-piece plug connectors are included for ease of installation and for removal during strike servicing without cutting or re-terminating wires.

Von Duprin 6100 Electric Strike Parts: Box Assembly Selection Guide

The box assembly is the heart of the 6100. It contains the solenoid, the keeper release mechanism, and all internal components that control strike operation. When a 6100 fails to release or fails to hold, the box assembly is the replacement unit. SecurityParts.com stocks 30 OEM box assemblies for the 6100 series, organized by fail mode, voltage, and application type.

Before ordering any box assembly, confirm three things from the installed device: the fail mode (fail safe or fail secure), the operating voltage (12VDC, 24VDC, or AC), and whether a dual switch is required. These three variables determine the correct part number. All available box assemblies are at the 6100 series parts catalog.

Fail Safe Box Assemblies (12VDC)

Dual switch (DS) box assemblies include a door position switch and a bolt position switch in addition to the standard solenoid. These switches send status signals to an access control panel confirming door position and latch state. DS assemblies are required when the access control system calls for strike status monitoring.

If the existing installation has wiring beyond the standard two power leads, a DS assembly is installed. Count the wires before ordering.

• 111747 - Box Assembly, Fail Safe, Dual Switch (DS), 12VDC
• 111749 - Box Assembly, Fail Safe, Dual Switch (DS), 24VDC

Von Duprin 6100 Power and Voltage Requirements

The 6100 ships standard as 24VDC fail secure. Confirm the installed voltage before ordering a replacement box assembly.

• 24VDC: Standard factory voltage. Continuous duty at 0.33 A. Most common in commercial installations.
• 12VDC: Optional at time of original order. Used in installations where the access control panel supplies 12VDC.
• AC operation: Optional. The 6100 can operate on AC power, unlike the 5100 which requires a DC rectifier for AC input. Confirm AC compatibility from the installed device label before ordering AC-rated box assemblies.

16VDC and 28VDC solenoid variants exist for legacy strikes at those voltages. Contact SecurityParts.com at 845-935-0301 before ordering if the device label shows a non-standard voltage.

The 6100 shares 6000 Series solenoid kits (050237, 050239, 050240) with the 6200 series as standalone solenoid replacements when the box assembly housing is intact. For access control integration context, see the access control and commercial door hardware integration guide.

Von Duprin 6100 Fail Safe vs Fail Secure: How to Identify the Installed Configuration

Ordering the wrong fail mode is the most common 6100 parts ordering error. The installed fail mode cannot be changed by swapping the box assembly alone in some configurations. Confirm the fail mode before placing any order.

How to Confirm Fail Mode Without Power

The most direct identification method is the device label. The fail mode is printed on the label affixed to the strike body. With the strike removed from the frame, locate the label and read the fail mode designation: FS for fail safe, FSE for fail secure.

If the label is illegible, the fail mode can be identified by function. Disconnect power to the strike. If the keeper (movable lip) can be pushed inward manually with the door latch, the strike is fail safe - it releases without power. If the keeper is rigid and cannot be moved without power applied, the strike is fail secure.

Fire-Rated Applications Require Fail Secure

On fire-rated assemblies, the electric strike must be fail secure. A fail-safe strike on a fire-rated opening creates a code compliance gap. Confirm the door fire rating before ordering. See the commercial door fire rating guide and the ANSI/BHMA standards guide.

Von Duprin 6100 Compatibility: Rim Exit Devices and Retrofit Applications

The 6100 is designed for rim exit devices. Compatibility extends across Von Duprin and Falcon rim series devices, as well as retrofit applications for legacy rim nightlatch hardware.

Von Duprin and Falcon Rim Exit Device Compatibility

The 6100 is compatible with Von Duprin rim series exit devices including the 98/99, 22, 33A/35A, 75, 78, 88, and 55 Series rim devices, as well as Falcon 19, 24, and 25 Series rim devices. For a full comparison of how Von Duprin rim exit device series differ from each other, see the Von Duprin exit device series comparison. For rim exit device part details, see the rim exit devices guide.

Retrofit Applications

The 6100 retrofits many legacy rim electric strike installations. Specific models replace Folger Adams 310-4 hardware with minor frame preparation. If replacing a Folger Adams unit, confirm the specific 6100 model from the existing device label or call SecurityParts.com before ordering.

Single Door and Double Door Applications

The 6100 series includes models for both single door and double door applications. Double door variants cover openings without a center mullion where the strike must span the gap between active and inactive leaves. Confirm the door configuration (single or double, with or without mullion) before selecting a 6100 model.

Common Von Duprin 6100 Electric Strike Problems and How to Diagnose Them

Most 6100 field failures are diagnosable without special equipment. The two-piece plug connector design makes the 6100 easier to service than many competing electric strikes because the box assembly can be removed and replaced without cutting wires.

Strike Does Not Release When Power Is Applied

Verify power at the strike terminals using a multimeter before concluding hardware failure. Measure voltage at the plug connector. If the correct voltage is present and the strike does not release, the box assembly solenoid has failed. If no voltage is present, the fault is upstream in the access control panel, power supply, or wiring run, not in the strike itself.

For fail-secure installations: if power is present and the strike does not release, the box assembly is the likely replacement. For fail-safe installations: if the strike does not release when power is removed, the same diagnosis applies.

Strike Releases Intermittently

Intermittent release is almost always a voltage drop at the strike. Measure voltage under load (solenoid energized). If voltage drops significantly below the rated value, the power supply or wire run is undersized. This is a wiring issue, not a box assembly failure. Replacing the box assembly will not resolve a voltage drop.

Keeper Does Not Return to Locked Position

If the keeper releases correctly but does not return to the locked position after the door closes, the keeper return spring inside the box assembly has failed. The correct repair is a full box assembly replacement. The keeper return mechanism is internal and is not serviceable as a standalone component.

Strike Operates Correctly But Door Does Not Latch

If the strike operates correctly but the door latch does not engage the keeper, the fault is alignment between the exit device latch and the strike keeper, not a failure of the strike itself. Check the keeper height and door gap before concluding that the strike is defective. For general commercial door hardware troubleshooting, see the commercial door hardware troubleshooting guide.

Von Duprin 6100 vs 6200 vs 6300: Which Series Is Right?

The 6100, 6200, and 6300 are all heavy-duty, fire-rated Von Duprin electric strikes, but they serve different applications. Understanding the key differences prevents wrong-series orders.

• 6100: Rim exit devices only. Five models covering single and double door configurations. Standard fail secure 24VDC. UL10C fire rated. Stainless steel construction with integrated faceplate.
• 6200: The most versatile series. 17 configurations covering cylindrical locks, mortise locks, deadlatches, and rim exit devices. Also UL10C fire rated. Shares the 6000 Series solenoid kits with the 6100.
• 6300: Surface-mount heavy-duty series for rim exit device applications where flush mounting is not possible or where the door prep does not accommodate a standard 6100 installation. The 6300 mounts on the surface of the frame rather than recessed into the frame.

Rim exit device with standard frame = 6100. Frame requires surface mount = 6300. Lock type other than rim exit device = 6200. Browse the 6300 series catalog and the Von Duprin 5100 guide for comparison.

How to Order the Correct Von Duprin 6100 Replacement Part

1. Confirm the hardware is a 6100. The series designation is on the strike body label (6100, 6111, 6112, etc.). If the label shows a different series, identify the correct series before ordering.
2. Identify the fail mode. Read FS or FSE from the device label. If illegible, test as described above. Fail safe and fail secure box assemblies are not interchangeable.
3. Confirm the operating voltage. Read from the device label or measure at the plug connector. Standard is 24VDC. For non-standard voltages, call 845-935-0301 before ordering.
4. Confirm dual switch. Count wires at the plug connector. Two wires = standard. Additional wires = dual switch (DS). Ordering a standard assembly for a DS installation removes status monitoring from the access control system.
5. Order the correct box assembly. Match fail mode, voltage, and DS requirement to the part number. All 30 box assembly options are at securityparts.com/series/6100-electric-strikes-2.
