Dortronics 3300D – Frequently Asked Questions

1) Will the Dortronics 3300D electric strike fit a standard ANSI frame cutout in an aluminum jamb?
Yes. The 3300D ships with a stainless steel ANSI style strike plate sized 4-7/8 inches high by 1-1/4 inches wide, which matches most aluminum frame cutouts. The faceplate is 1-3/16 inches deep with a 1-3/4 inch overall width, so allow for that depth behind the jamb face.
2) Can this Dortronics strike be used on a wood or hollow metal door frame, or do I need a different model?
Same strike works. An 8 inch tall strike plate is included in the box for wood and hollow metal frames. That prep is 7-15/16 inches high by 1-7/16 inches wide, with a faceplate 1-3/16 inches deep and 1-13/16 inches overall width. No separate part number to order.
3) What size latchbolt will the Dortronics 3300 series keeper accept?
The deep keeper pocket takes latch bolts up to 1/2 inch long with no modification, which covers most cylindrical and mortise latches as well as a range of other bolt type hardware. If your lock throws a 5/8 inch bolt, look at a strike built for that projection instead, such as the SDC 15 Series or the Hager 2925.
4) Is the Dortronics 3300D fail-safe or fail-secure, and can I change it in the field?
It leaves the factory fail-secure, meaning the door stays locked when power drops. A screwdriver adjustment in the field converts it to fail-safe, which unlocks on power loss. No special tools required, so you can set it on site to suit the egress and life safety plan for the opening.
5) What does the D in Dortronics 3300D add, and what can I wire it to?
The D is the latch bolt monitoring switch. It is an SPDT form C dry contact that reports whether the latch is seated, so you can show secure or unsecure door status at a panel, or signal an access control system when someone mechanically retracts the latch from the lever side. Order the plain 3300 if you do not need monitoring.
6) What power supply do I need for a Dortronics 3300 series electric strike?
It runs on either 12 or 24 VDC. Current draw is 280mA at 12 VDC and 140mA at 24 VDC, so size the supply and the wire run off whichever voltage you are using. It is continuous duty rated and can be held energized indefinitely without overheating.
7) What is a fire-rated alternative to the Dortronics 3300D electric strike?
The Dortronics 3300 series is described as UL security listed under burglary-resistant electric locking mechanisms, which is a security listing rather than a fire door listing. If the opening is a labeled fire door, look at the Hager 2930, a fire rated Grade 1 electric strike for cylindrical and mortise locks with 12/24VDC dual voltage, or the Von Duprin 4211 32D, a Grade 1 fire rated strike for cylindrical locks with 12/24VDC field-selectable voltage. The Camden CX-ED1410 and CX-ED1420 universal ANSI strikes are also Grade 1 and fire rated. All three keep the dual-voltage flexibility a 3300D installer expects.
8) Which other electric strikes offer latch bolt monitoring like the Dortronics 3300xD?
The 3300xD adds an SPDT latch bolt monitoring switch with a form C dry contact output that can report secure or unsecure door status to an access control system. For the same monitoring function from another maker, the Hager 2945 is a fire rated rim exit strike with field selectable fail safe or fail secure operation and a latchbolt monitor, and the Camden CX-ED1799L-8 is a fire rated Grade 1 strike with dual monitoring supplied with eight faceplates. The Hager is built for rim exit device latches rather than the bolt-type hardware the 3300 deep keeper accepts.
9) Is the Dortronics 3300 the right strike for a rim exit device or surface vertical rod door?
No. The 3300 is a frame-mounted strike sized for an ANSI 4-7/8 by 1-1/4 prep with a deep pocket for bolt type hardware up to 1/2 inch. For a rim exit device, the SDC 30-4 is a rim mount strike for a 3/4 inch Pullman latchbolt in stainless steel, and the Hager 2945 is a fire rated rim exit strike with field selectable operation and a latchbolt monitor. For surface vertical rods, the HES Folger Adam 310-4-2 is a complete Grade 1 electric strike pac built for that application. For a pair of doors, the Rockwood double door strike uses a 3/4 keeper and is Grade 1 and fire rated.
10) What should I use instead of the Dortronics 3300 on a mortise lock opening?
The 3300 is non-handed with a deep keeper that takes a wide variety of bolt type hardware up to 1/2 inch, but a mortise lock with a deadlatch and auxiliary bolt is often better served by a strike built for it. The Securitron MUNL mortise UnLatch strike is Grade 1 and fire rated for that application, the Von Duprin 6210 is a heavy duty Grade 1 strike for mortise locks at 24 VDC fail-secure, and the Von Duprin 6400 32D is a modular Grade 1 strike that covers mortise or cylindrical locks. The Hager 2930 also handles both cylindrical and mortise locks with 12/24VDC dual voltage, matching the 3300 dual voltage input.
11) I need an AC-powered electric strike, not 12/24VDC. What are the options?
The Dortronics 3300 draws 280ma at 12 VDC and 140ma at 24 VDC, so it is a DC device. If your power supply is AC, the Trine 004 runs on 8-16VAC, is fail secure, is fire rated, and uses a 6-1/4 by 1-3/8 inch faceplate with up to 5/8 inch throw. The Trine 2001 accepts 16-24VAC or DC, is fail secure and fire rated, with a 5-7/8 by 1-1/4 inch faceplate and up to 5/8 inch throw. Note both use a different faceplate size than the 3300 ANSI 4-7/8 by 1-1/4 plate, so the frame prep is not a direct carryover.
12) Does the Dortronics 3300D have to be handed left or right when I order?
No handing to specify. The 3300 and 3300xD strikes are non-handed and install on left or right hand doors as supplied.
13) I need a field-reversible fail safe or fail secure strike with latch monitoring. What are my options besides Dortronics?
Dortronics 3300D gives you both, a screwdriver-adjustable fail-safe/fail-secure mode and an SPDT latch monitor. Comparable choices include the Hager 2945 rim exit strike, which is field selectable fail safe/fail secure with latchbolt monitor and fire rated, and the Camden CX-ED1799L-8 Grade 1 dual monitor strike shipped with eight faceplates. The Hager 2928-SC is field reversible but sold without the monitor call-out.
14) What is a lower-cut or retrofit option if I do not want to cut a full ANSI pocket for the Dortronics 3300?
The 3300 needs a 4-7/8 by 1-1/4 ANSI frame prep, or a 7-15/16 by 1-7/16 prep in a wood frame. If cutting the frame is the problem, the Locknetics NC450 is a no cut electric strike, and the Camden CX-ED1689L-4 is a fire rated universal low profile strike supplied with four faceplates so it can be matched to several existing cutouts. The Camden CX-ED1799L-8 ships with eight faceplates for the same reason.
15) Which heavy duty Grade 1 strikes compete with the Dortronics 3300 for high traffic openings?
The 3300 is continuous duty rated, may be energized indefinitely, and is tested to 250,000 cycles, with a 1,000 lb static strength rating on the stainless steel jaw and strike plate. Peers carrying a published Grade 1 heavy duty classification include the Alarm Controls AES-100, the Von Duprin 4211 32D for cylindrical locks, the Von Duprin 6210 for mortise locks, and the Von Duprin 6400 32D modular strike that serves mortise or cylindrical locks in satin stainless steel with a 3-hour UL 10C fail-secure rating. The Locknetics MDS100 and MS100 in US32D are also catalogued as heavy duty.
16) Is there a simpler electric strike than the Dortronics 3300 for a light duty interior door?
Yes. The 3300 is a continuous duty strike tested to 250,000 cycles with a 1,000 lb static rating and an optional latch monitor, which is more strike than a low traffic interior opening needs. Lighter options include the Trine 001 Series, a fail-secure light commercial strike with a 5-7/8 by 1-1/4 faceplate, the RCI 15BS economy strike for special offset latch entry with fail-secure operation, and the SDC 25 Series value strike for 1/2 inch latchbolts, which matches the 1/2 inch bolt the 3300 keeper accepts.
17) Do the HES 1500 and 1600 items work as a replacement for a Dortronics 3300?
No, and it is an easy mix-up when searching by strike series. The HES 1500 and HES 1600 items are electric strike accessories for those Grade 1 fire rated series, not complete strike assemblies, so neither replaces a 3300 as a working unit. If you want a complete HES-family strike body instead of the Dortronics, the Folger Adam 310-1(X) is the strike body for 1/2, 5/8 or 3/4 inch throw latchbolts and carries a Grade 1 fire rating.
18) What finish does the Dortronics 3300 series come in, and will it match my other door hardware?
One finish across the series: US32D brushed stainless steel on the latch housing, with a 1/8 inch thick US32D brushed stainless faceplate. US32D is the standard satin stainless commercial finish, so it sits alongside 630 lever trim and exit devices on the rest of your openings.
19) Which strikes match the US32D brushed stainless finish of the Dortronics 3300?
The 3300 series uses a US32D brushed stainless steel latch housing with a 1/8 inch thick US32D brushed stainless faceplate. Peers supplied in the same finish designation include the Locknetics CS450-32D, the Locknetics MDS100 US32D, the Locknetics MS100 US32D and the Locknetics NC450 US32D, along with the Von Duprin 4211 32D and the Von Duprin 6400 32D in satin stainless steel. That keeps a fleet of openings visually consistent when you are mixing brands across a building.
