What Is the Von Duprin 5100 Electric Strike?

The Von Duprin 5100 is a medium-duty electric strike for commercial cylindrical lock and deadlatch applications. Three faceplates are included in every box to cover hollow metal, wood, and aluminum frame applications. The power fail mode is field selectable. The solenoid accepts 12 or 24 VDC on a single unit.

The 5100 is positioned as a general commercial and retail electric strike for interior and exterior doors where fire-rated hardware is not required. It is compatible with Schlage, Falcon, and most other manufacturers' cylindrical locks with a latch throw up to 5/8 inch, as well as many aluminum narrow-stile deadlatches.

It is not specified for high-security, high-cycle, or fire-rated applications. The 5100's strength is flexibility and ease of installation on standard commercial openings. For wiring principles that apply across all Von Duprin series, see the commercial electric strike parts guide.

Von Duprin 5100 Electric Strike Parts and Replacement Components

SecurityParts.com stocks six OEM replacement parts for the Von Duprin 5100 series. All are available at the 5100 series parts catalog.

050031 Electric Strike Faceplate

Von Duprin 5100 Electric Strike Faceplate (part 050031). Standard finish. OEM replacement at SecurityParts.com.

The faceplate mounts flush with the frame face and provides the latch pocket. The standard 5100 ships with three faceplates (hollow metal, wood, and aluminum), so replacement is needed when the installed faceplate has been damaged. Part 050031 is the standard finish replacement. Order it when the faceplate needs replacing and the housing and solenoid remain functional.

050034 Solenoid Kit 12/24VDC

Von Duprin 5100 Solenoid Kit 12/24VDC (part 050034). OEM replacement at SecurityParts.com.

The solenoid is the electromechanical component that retracts or holds the keeper when power is applied. It is the most commonly replaced internal component in any electric strike, and the 5100 is no exception. When the strike clicks but the keeper does not move, or when the strike does not respond to power at all, the solenoid is the first component to test.

Solenoid power specifications for the 5100:

• 12 VDC: 0.38 A
• 24 VDC: 0.19 A
• Input: non-polarized
• AC operation: not supported directly. Requires Von Duprin SO12 or SO24 rectifier kit to convert AC to DC.

Part 050034 is the complete solenoid kit for the 5100, covering both 12 and 24 VDC. Before ordering, confirm the supply is DC, not AC.

PKGMTG.1004 Mounting Package

Von Duprin 5100 Mounting Package (PKGMTG.1004). Standard finish. OEM replacement at SecurityParts.com.

The mounting package contains the hardware required to secure the 5100 strike body to the frame. Order when mounting hardware is lost, corroded, or inadequate for the frame condition.

PKGMTG.1004 is the standard finish mounting package. Order this when the existing hardware finish is standard and the frame material is compatible with the standard mounting configuration.

PKGMTG.1005 Mounting Package (Black)

Von Duprin 5100 Mounting Package Black (PKGMTG.1005). OEM replacement at SecurityParts.com.

PKGMTG.1005 is the black finish mounting package. Order this when the installed 5100 is in a black finish configuration. Confirm the installed finish before ordering.

PKGSCR.1003 Screw Package

Von Duprin 5100 Screw Package (PKGSCR.1003). Standard finish. OEM replacement at SecurityParts.com.

PKGSCR.1003 is the standard finish screw package, containing fasteners used to secure the faceplate and strike body. Order when fasteners are stripped, lost, or corroded.

PKGSCR.1004 Screw Package (Black)

Von Duprin 5100 Screw Package Black (PKGSCR.1004). OEM replacement at SecurityParts.com.

PKGSCR.1004 is the black finish screw package. Order when the installed 5100 is black finish.

Von Duprin 5100 Compatibility and Applications

The 5100 is compatible with the following lock types and door configurations:

• Lock type: Cylindrical locks and deadlatches only. The 5100 is not compatible with mortise locks or rim exit devices.
• Latch throw: Up to 5/8 inch. Confirm the latch throw on the installed cylindrical lock before specifying the 5100.
• Cylindrical lock brands: Compatible with Schlage, Falcon, and most other manufacturers' cylindrical locks meeting the 5/8-inch throw requirement.
• Narrow stile deadlatches: Compatible with many aluminum narrow-stile deadlatch applications.
• Door applications: Interior and exterior commercial doors. Not for fire-rated door assemblies.

The 5100 is not specified for high-security or institutional-grade applications requiring the cycle count and abuse resistance of the 6200 or 6300 Series. It is best suited for retail and light commercial openings where cylindrical lock hardware is installed and fire rating is not a requirement.

Von Duprin 5100 Faceplate and Frame Compatibility

One of the 5100's key advantages is that every unit ships with three faceplates, covering the three most common commercial frame types:

• Hollow metal frame faceplate
• Wood frame faceplate
• Aluminum frame faceplate

This multi-faceplate approach eliminates the need to specify the frame type at the time of ordering the device. The installer selects and installs the correct faceplate on site. The adjustable keeper further accommodates frame variations, including openings with weather stripping or tight door preps where a fixed keeper would cause alignment problems.

When replacing a faceplate, confirm which of the three faceplates was installed. Part 050031 is the standard finish replacement. Call 845-935-0301 before ordering if the installed faceplate finish does not match standard.

Von Duprin 5100 Power and Wiring Requirements

The 5100 solenoid is rated for 12 or 24 VDC. A single unit handles both voltages, which simplifies multi-door projects where panel voltage may vary.

Key wiring facts for the 5100:

• Power input is non-polarized. Wire polarity does not matter for DC operation.
• The strike will not operate reliably on AC power. If the power supply outputs 12 or 24 VAC, a Von Duprin SO12 or SO24 AC-to-DC rectifier kit is required to convert the supply before it reaches the strike.
• Current draw: 0.38 A at 12 VDC, 0.19 A at 24 VDC.
• For DC power supply selection, the Von Duprin PS902 series power supply is a recommended option for this strike.

A common field problem is applying 24 VAC directly to the 5100. In this configuration the strike may work in one door handing but not when flipped to the other handing. This is not a defective strike. It is a wiring mismatch. Install the SO24 rectifier kit to convert to 24 VDC and the problem resolves.

For wiring diagrams and schematic references, see the electric strike schematic diagram guide.

Fail-Safe vs Fail-Secure on the Von Duprin 5100

The 5100 allows the power fail mode to be selected in the field. No tools are required for conversion. Understanding which mode is installed is essential before ordering a replacement solenoid or troubleshooting a strike that is not responding as expected.

• Fail Safe (FS): The strike releases the latch and allows the door to open when power is lost. This is the appropriate specification for emergency egress applications where the door must be freely openable during a power failure.
• Fail Secure (FSE): The strike holds the latch and keeps the door locked when power is lost. This is appropriate for security-sensitive openings where maintaining the locked state during a power failure is required.

To identify the mode on an installed 5100: if the door opens freely when the power supply is disconnected, it is fail safe. If the door remains locked when power is disconnected, it is fail secure.

When troubleshooting a 5100 that appears non-functional, confirm the fail mode before concluding there is a hardware fault. A fail-secure strike with no power at the strike will remain locked - which is correct operation, not a failure. A fail-safe strike with no power will release - also correct. The fault is only confirmed when the strike does not behave consistently with its configured fail mode.

Is the Von Duprin 5100 Fire Rated?

No. The Von Duprin 5100 electric strike is not listed for fire-rated door assemblies. It cannot be installed on a fire-rated opening as the primary latching mechanism.

If the door assembly carries a fire rating, the 5100 is not the correct specification. The Von Duprin 6200 or 6300 Series electric strikes carry UL fire-exit hardware listing and are appropriate for fire-rated door assemblies where electric strike hardware is required.

Before installing or replacing an electric strike on any commercial door, confirm the fire rating of the door assembly. A fire-rated door with a non-rated electric strike installed as the latch mechanism creates a code compliance gap that may be identified during AHJ inspection. For fire door hardware requirements and what listings apply to fire-rated assemblies, see the commercial door fire rating guide.

Common Von Duprin 5100 Electric Strike Problems

Most 5100 field failures are diagnosable without special equipment. The following are the most common problems and their most likely causes:

Strike Clicks But Keeper Does Not Move

The solenoid is activating but the mechanical release is not functioning. This indicates a solenoid assembly failure or a mechanical jam in the keeper mechanism. Check the keeper for physical obstructions first. If the keeper is free but not retracting, the solenoid kit (050034) is the likely replacement part.

Strike Does Not Respond to Power

Verify power at the strike terminals before concluding hardware failure. Measure voltage at the strike with a multimeter. If the correct DC voltage is present at the strike and there is no solenoid activation at all, the solenoid has failed and needs replacement (050034). If no voltage is present, the fault is upstream in the power supply or wiring, not in the strike itself.

Strike Works in One Door Handing But Not the Other

This is almost always caused by AC power being applied to the strike without a rectifier. The 5100 solenoid is designed for DC power. AC power can cause directional behavior because the solenoid coil responds asymmetrically to alternating current polarity. Install the Von Duprin SO12 or SO24 rectifier kit to convert AC to DC before the strike.

Door Does Not Latch When Strike Is Powered

Confirm the fail mode configured on the strike. In fail-safe mode, the door unlatches when power is present. If the strike is wired in a normally-energized configuration on a fail-safe unit, the door will remain unlatched whenever the system is powered. Review the system design to confirm that the power control logic matches the configured fail mode.

Von Duprin 5100 vs 6200: Which Electric Strike Is Right?

The 5100 and 6200 are both Von Duprin electric strikes, but they serve different applications. Understanding the key differences prevents wrong-product orders.

• Fire rating: The 5100 is not fire rated. The 6200 carries UL fire-exit hardware listing. If the door is fire-rated, the 6200 is the correct specification.
• Lock compatibility: The 5100 works with cylindrical locks and deadlatches only. The 6200 also works with mortise locks and rim exit devices.
• Construction grade: The 5100 is medium-duty. The 6200 is heavy-duty stainless steel for high-cycle institutional applications.

If the opening now requires fire-rated hardware or mortise lock compatibility, specify the 6200 rather than a like-for-like 5100 replacement. Browse the 6100 series and 6300 series parts catalogs at SecurityParts.com for comparison.

How to Choose the Correct Von Duprin 5100 Replacement Part

Follow this sequence before placing any 5100 parts order:

1. Confirm the device is a 5100. The model number is stamped on the strike housing. If the model number starts with 5100, you are in the right series. If it starts with 6100, 6200, or 6300, the parts are different and not interchangeable.
2. Identify the failing component by symptom. No response to power: solenoid (050034). Damaged faceplate: 050031. Missing or corroded mounting hardware: PKGMTG.1004 (standard) or PKGMTG.1005 (black). Stripped or missing fasteners: PKGSCR.1003 (standard) or PKGSCR.1004 (black).
3. Confirm the finish. Standard finish parts (050031, PKGMTG.1004, PKGSCR.1003) and black finish parts (PKGMTG.1005, PKGSCR.1004) are separate SKUs. Ordering the wrong finish results in a visible mismatch on the frame.
4. Verify power supply before ordering a solenoid. A solenoid that fails because of an AC power input issue without a rectifier will fail again after replacement if the wiring is not corrected. Confirm DC voltage is present at the strike before concluding solenoid failure.
5. Call before ordering if unsure. The SecurityParts.com team is available at 845-935-0301 for pre-order compatibility confirmation. This prevents returns and keeps the opening in service.
