Von Duprin Electric Strikes: 6200 and 6300 Series Models, Power and Installation

Von Duprin's 6200 Series strikes are for mortise or cylindrical locksets, and the 6300 mounts on the frame surface for rim exit devices. Model fit, power, fail mode, fire listings and monitoring, from Von Duprin's documents.

Quick answer

An electric strike is the part of the door frame that holds the latch and that electric power locks or unlocks; unlocked, it lets the door open with the latch still out. This page covers two of the seven strike series in Von Duprin's catalog: the 6200 Series, 17 models for mortise or cylindrical locksets, and the 6300, a surface mounted strike for rim exit devices (push bars whose latch sits on the face of the door). The 6200 Series comes standard as 24 VDC (volts of direct current) in fail secure mode, which needs power to unlock, and the 6300 is fail secure only, with field selectable 12 VDC or 24 VDC. Von Duprin lists both as "UL 10C 3-hour fire-rated (fail secure only)," and on the pair-door 6200 models an asterisk adds "When pair door has inactive leaf" (a leaf is one door of a pair; the inactive one normally stays shut). The local authority having jurisdiction (AHJ) decides what a fire-rated or exit-device opening requires.

Key takeaways

  • The 6200 Series model depends on the lock in the door: one model is for mortise locks without a deadbolt only, one for a mortise lock with a 1-inch throw deadbolt, and 15 for mortise locks without a deadbolt or cylindrical locks.
  • The 6300 mounts on the surface of the frame for rim exit devices. Von Duprin says it is designed for use with Von Duprin 98/99, however it can be used with most rim exit devices.
  • A fail secure strike needs power to unlock the strike lip (the part that holds the latch); a fail safe strike needs power to lock it. Von Duprin's catalog says: "Building codes prohibit the use of fail-safe strikes on fire-rated openings."
  • Von Duprin's conversion sheet warns that converting or modifying a 6000 series strike invalidates the UL fire listings and requires removal of the UL fire label.

Identify

Which Von Duprin strike do I have?

The 6300 mounts on the face of the frame and projects 3/4 inch; Von Duprin says it requires no alteration or cutting to the existing frame. Each 6200 Series model has a backbox, the housing behind the face plate, and the table lists its depth.

Within the 6200 Series, the model depends on the lock in the door, whether it is a single door or a pair, and the frame. A mortise lock has its body set into a pocket in the edge of the door; a cylindrical lock is a knob or lever lock fitted through a round hole in the door. Hollow metal is a steel frame.

Of the five other series in the catalog, the 6100 Series is also titled as strikes for rim exit devices; this page leaves it out.

Replacement

Which model replaces an older strike?

Von Duprin's catalog names 6200 Series replacements for some older Von Duprin and Folger Adam strikes.

Locks

Which locks does a 6200 Series strike work with?

Von Duprin prints two charts of mortise locks for the 6200 Series. One is for the 6210; the other is for the 14 models in the table caption.

The 6200 Series data sheet's charts differ from the catalog's in two places: the data sheet also lists Best 45H in the chart for the 14 models, and it writes the Falcon models with an MA prefix.

For cylindrical locks, the chart for the 14 models gives the latchbolt projection, how far the latch sticks out, as 1/2 inch to 3/4 inch for Baldwin, Corbin, Falcon, Russwin, Sargent and Yale, and 3/8 inch to 3/4 inch for Best and Schlage. A note says signalling may not function when using a 3/8-inch throw bolt, and that deadlocking cannot be guaranteed with all locks.

Von Duprin says it cannot guarantee compatibility, as other manufacturers' designs may change without notice. For a lockset not listed, or a strike being retrofitted to an existing application, it says to contact Von Duprin Technical Support.

The instruction sheets for the 6210 and the three 6211 versions each open with the same note: deadbolt will not function with this strike. The 6216 is the one model for a mortise lock with a 1-inch throw deadbolt, and the deadbolt must be manually operated.

Exit devices

Will a 6300 work with my exit device?

On a rim exit device, a push bar whose latch sits on the face of the door at its edge, the 6300 is the strike that latch engages.

The 6300 instructions say maximum latch projection is essential to obtaining full holding force, and that the installer should ensure the exit device functions as intended for life safety concerns by verifying electric strike and exit device compatibility.

They also say: "When installed in a fail secure manner, the local authority having jurisdiction shall be consulted with regard to the use of selected panic hardware to ensure emergency exit from the secured area."

Installations of the rim strike qualify as indoor use only when not continuously exposed to an outdoor environment.

Power

How is it powered?

Inside the strike, a solenoid, an electric coil, moves the lock, and it runs on direct current (VDC). The 6200 Series is 24 VDC standard with 12, 16 and 28 VDC operation optional. The 6300 has field selectable voltage, 12 VDC or 24 VDC.

The 6210 and 6211 instruction sheets add that the current figures are also shown on the strike label, and that the DC input is nonpolarized: either wire can take the positive side.

For an AC (alternating current) supply, both data sheets list optional rectifier kits, one converting 12 VAC to 12 VDC and one 24 VAC to 24 VDC; the 6200 instruction sheets label them SO-12 and SO-24.

Two connectors ship with the 6300, and the one that matches the available voltage at the opening is used. The 6300 instructions call them wire harnesses and say to use the 12V harness for 12VDC and the 24V harness only for 24VDC; overheated or burnt coils caused by incorrect voltage/wire harness combinations will not be covered under warranty.

The catalog's wire size table for a current requirement of 0 to .5 amp at 24 VDC lists 18 gauge for wire runs up to 600 feet, 16 gauge for 600 to 900 feet and 14 gauge for 900 to 1,200 feet.

Power requirements. The data sheets list continuous duty, defined as energized 1 minute or more. The instruction sheets for the 6210, 6211, 6211AL and 6211WF print different current figures from the 6200 Series data sheet; both are shown.

Fail mode and fire doors

What happens when the power goes off, and what matters on a fire-rated door?

Fail secure and fail safe describe how the strike lip, the part of the strike that holds the latch, behaves with and without power. The 6200 Series comes standard in fail secure mode, and power failure mode is one of its ordering selections.

The catalog's 6000 Series page says FSE and FS strikes are field convertible with parts, and adds: "Building codes prohibit the use of fail-safe strikes on fire-rated openings."

Von Duprin's FS/FSE conversion sheet for the 6000 Series prints one warning twice: the conversion or modification of the 6000 series electric strikes invalidates the UL fire listings and requires removal of the UL fire label.

Both data sheets list UL 10C 3-hour fire-rated (fail secure only), UL 1034 for burglary-resistant electric door strikes and UL 294 for access control system. The 6300 also lists CSFM, the California State Fire Marshal.

On the pair-door 6200 models, the 3-hour entry carries a condition: when pair door has inactive leaf.

On the 6200 Series, the entry buzzer (EB) option is only available if fail-secure is specified; the 6300 data sheet lists the entry buzzer as optional.

Monitoring

Can the strike report whether the door is latched and locked?

The 6200 Series monitoring option is DS or DS-LC, dual monitor switches: two SPDT contacts (single-pole, double-throw: one common lead and two others). One switch monitors the tripper, which is depressed when the latchbolt is inserted into the strike pocket; the second monitors the strike lip, open or closed and locked.

Dual switch monitoring is factory installed only, and dual monitor switches are not available on open back strikes. The model tables show no DS entry for the 6221, 6222 and 6225.

Monitor switch ratings and leads. (C) marks the common lead. Von Duprin's documents rate the switches two ways; both are shown with their documents.

FAQ

Von Duprin electric strike questions

Which Von Duprin electric strike is listed for a 98 or 99 rim exit device?

The 6300. Its data sheet lists the VD 98/99 and 98/99-F Rim in its rim exit device compatibility chart, and Von Duprin says the strike is designed for use with Von Duprin 98/99.

Does a Von Duprin 6300 need the frame cut?

Von Duprin says the 6300 is surface mounted and requires no alteration or cutting to the existing frame. Its instructions call for two mounting holes and two locking holes, drilled and tapped, and a drilled wire access hole.

Is a Von Duprin 6211 fail safe or fail secure?

It comes standard as fail secure, like every 6200 Series strike, and fail safe is an ordering selection.

Can a fail safe Von Duprin strike go on a fire-rated door?

Von Duprin's catalog says: "Building codes prohibit the use of fail-safe strikes on fire-rated openings." For both the 6200 Series and the 6300, the UL 10C 3-hour fire rating is fail secure only.

What voltage is a Von Duprin 6200 or 6300 electric strike?

The 6200 Series is 24 VDC standard, with 12, 16 and 28 VDC operation optional; the 6300 has field selectable voltage, 12 VDC or 24 VDC. Both data sheets list optional rectifier kits for a 12 VAC or 24 VAC supply.
