Trine 3234-24DC-26D – Frequently Asked Questions

1) Will the Trine 3234 electric strike work with a standard cylindrical knob or lever lockset?
That is exactly what the 3234 is cut for. It is a mortise-type strike for cylindrical locks, and the keeper cavity is 5/8 inch wide by 1-1/8 inch high by 1/2 inch deep, so the latchbolt from a standard cylindrical knob or lever set sits in it. The lockset itself stays on the door and is untouched, key override and all. Release happens at the frame when the strike is energized, not at the lock. If the opening has a mortise lock or a rim exit device instead, the 3234 is the wrong strike for it.
2) Do I have to pick fail-safe or fail-secure when I order the Trine 3234, or can I flip it in the field?
Pick it when you order. On the 3234 the standard action is fail-secure, which unlocks when power is applied and stays locked on a power loss, and fail-safe is the RS reverse-action build that unlocks when power drops. They are separate part builds, not a jumper you move on the job. If you need one strike you can set either way after it is on the wall, the Hager 2925, Hager 2928 and Hager 2930 are all field reversible fail safe/fail secure. Worth settling before the order goes in, because swapping later means a new strike.
3) Is the Trine 3234 electric strike 12 or 24 volt, and is the voltage selectable?
The 3234 comes as either a 12 VDC strike or a 24 VDC strike, and voltage is fixed by which one you buy. There is no field-selectable dual-voltage version, so match it to the power supply or access control board before ordering. Both voltages are offered in fail-safe and fail-secure and in all three finishes. If you would rather stock one strike that works on either bus, the Von Duprin 4211 is 12/24 VDC field-selectable and the Dortronics 3300 Series runs 12/24 VDC.
4) How deep does the frame have to be for a Trine 3234 electric strike?
The 3234 mortises into the jamb with a 1 inch backset, which Trine calls the smallest in the industry. That is the number that matters on shallow frames, tight rabbets, and jambs already crowded with a closer tube or a raceway, where a deeper strike body simply will not go in. The faceplate is 2-3/4 by 1-1/8 inches. Cut the pocket for the 1 inch backset and confirm you have clearance behind the jamb face before you commit to the hole.
5) I am replacing an electric strike in an existing ANSI 4-7/8 inch strike prep. Will the Trine 3234 cover the old cutout?
It will not. The 3234 faceplate is 2-3/4 by 1-1/8 inches, and a standard ANSI prep is 4-7/8 by 1-1/4 inches, so you would be left with open jamb above and below the plate. For a drop-in on that prep, the Dortronics 3300 Series ships with a strike plate for ANSI prep at 4-7/8 by 1-1/4 inches, and the Adams Rite 7170 for hollow metal and wood jambs uses the same 1-1/4 by 4-7/8 faceplate. Use the 3234 where you are cutting fresh, or where the existing pocket is small.
6) Which electric strike works on a fire-rated door with a cylindrical lockset?
The Trine 3234 electric strike carries a fire rating of No, so a labeled fire door opening calls for a strike that is rated for it. The Von Duprin 4211 32D is a Grade 1 fire-rated electric strike for cylindrical locks with 12/24 VDC field-selectable operation. The Adams Rite 7240 is a fire-rated electric strike for cylindrical locksets with 5/8 inch latchbolt projection. The Hager 2930 is a fire-rated Grade 1 strike for cylindrical and mortise locks with 12/24VDC dual voltage, and the SDC 45F is a fire-rated strike for 5/8 inch latchbolt with a radius corner faceplate.
7) What electric strike fits an aluminum storefront jamb instead of a 2-3/4 inch mortise strike?
The Trine 3234 is a 2-3/4 inch by 1-1/8 inch mortise type strike on a 1 inch backset for cylindrical locks, which is a jamb cutout profile rather than an aluminum stile profile. For aluminum jambs, the Adams Rite 7100 Series uses a flat faceplate measuring 1-1/4 inch by 4-7/8 inch, and the Adams Rite 7160 uses the same 1-1/4 inch by 4-7/8 inch faceplate. The Adams Rite 7170 carries that faceplate size for hollow metal and wood jambs.
8) Will an electric strike built for a mortise lock or an exit device drop into a cylindrical lock opening?
No. The Trine 3234 is built for cylindrical locks, with a mortise type body on a 1 inch backset and a cavity 5/8 inch wide, 1-1/8 inch high and 1/2 inch deep to receive a cylindrical latch. Strikes prepped for other latches include the Von Duprin 6210 for mortise locks, the Securitron MUNL mortise unlatch strike, the SDC 30-4 rim mount strike for a 3/4 inch Pullman latchbolt, the HES Folger Adam 310-4-2 pac for surface vertical rods, and the Hager 2945 rim exit strike. The Von Duprin 6400 32D is a modular strike for mortise or cylindrical locks, so it spans both.
9) Can fail safe or fail secure be switched in the field, or does it have to be picked when ordering?
On the Trine 3234, the mode is a build choice made at order: the standard action is fail-secure, which unlocks with power, and the RS reverse action is fail-safe, which unlocks when power is off. Strikes that reverse in the field include the Hager 2925, which has field reversible fail safe/secure operation with a 5/8 inch latch, the Hager 2928, and the Hager 2930, which is fire rated and Grade 1 for cylindrical and mortise locks. The Hager 2945 has field selectable fail safe/fail secure with a latchbolt monitor.
10) Is the Trine 3234 electric strike handed? Do I need to say left or right hand when I order?
Non-handed, so one part covers both hands and you do not specify swing on the order. That also means a contractor stocking a truck or a property manager buying for a run of openings can carry a single strike for doors swinging either direction. What you do have to specify is voltage, fail-safe or fail-secure, and finish.
11) My door has a mortise lock, not a knob. What electric strike should I use instead of the Trine 3234?
The 3234 is cut for cylindrical locks, so a mortise lock latch is the wrong pairing. For mortise locks, the Von Duprin 6210 is a 24 VDC fail-secure strike with a UL 10C fire rating, the Securitron MUNL Mortise UnLatch is Grade 1 and fire rated, and the Von Duprin 6400 is a Grade 1 modular strike that handles mortise or cylindrical locks, which is the one to look at if you are standardizing across a building with both lock types.
12) Will a Trine 3234 electric strike release a rim exit device?
No. The 3234 takes the latchbolt of a cylindrical lockset in a jamb pocket, and a rim exit device throws a large pullman latch that needs a strike built for it. For an exit device, look at the SDC 30-4, a rim mount strike for a 3/4 inch pullman latchbolt in stainless steel, or the Hager 2945 rim exit strike, which is fire rated with a latchbolt monitor and field selectable fail safe or fail secure. For surface vertical rods, the HES Folger Adam 310-4-2 is a complete strike pac.
13) Is the Trine 3234 strike heavy duty enough for a busy apartment entry or a school corridor?
Rated at 500,000 life cycles with 1,200 pounds of static holding force and 70 ft-lb of dynamic force, so it is a commercial-duty part rather than a light residential one. The locking parts are all stainless steel and the latch is a solid cast stainless piece with a heavy-duty latch spring, which is what survives a high-traffic entry where the door gets pulled before the buzz finishes. It is rated commercial. Do not put it on a fire door, and do not put it on an exterior gate.
14) Can the Trine 3234 stay energized all day, or will it burn out on continuous duty?
The standard 3234 is intermittent duty, meaning it is meant to be pulsed for a release, not held on. If your access control holds the strike energized for long stretches, such as a fail-safe door tied to an alarm or a lobby unlocked through business hours, order the LC version, which is rated for both intermittent and continuous duty. Getting this wrong is a common way an electric strike cooks itself, so match the duty rating to how the door is actually run.
15) How do I match an electric strike to the latchbolt throw on the lock already in the door?
Match the keeper cavity to the latch. The Trine 3234 has a cavity 5/8 inch wide, 1-1/8 inch high and 1/2 inch deep behind a solid cast stainless steel latch. Among other strikes, the SDC 25 Series is built for a 1/2 inch latchbolt and the SDC 15 Series for a 5/8 inch latchbolt with 12/24 VDC operation. The Adams Rite 7240 takes a 5/8 inch latchbolt projection, the HES Folger Adam 310-1(X) strike body covers 1/2 inch, 5/8 inch or 3/4 inch throw latchbolts, and the SDC 30-4 takes a 3/4 inch Pullman latchbolt.
16) Which electric strike sends latch status back to the access control panel?
The Trine 3234 is a 12 VDC or 24 VDC strike with fail-secure or fail-safe operation, silent operation and 1,200 pounds of static holding force. When the panel also needs a latch position input, the Dortronics 3300 Series includes a latch bolt sensing switch and runs 12/24VDC, the Hager 2945 is a fire rated rim exit strike with a latchbolt monitor, and the Camden CX-ED1799L-8 is a dual monitor Grade 1 strike supplied with 8 faceplates.
17) Is there an electric strike rated for an exterior gate rather than an interior door?
The Trine 3234 is an indoor commercial strike and is not outdoor rated. For gates and exposed openings, the Camden CX-ED1959 Series is an outdoor rated electric gate strike.
18) What electric strike should a crew carry when the frame prep is unknown until they are on site?
The Trine 3234 comes with one 2-3/4 inch by 1-1/8 inch faceplate on a 1 inch backset mortise body, so the prep is known before the truck is loaded. Strikes that carry their own range of preps include the Camden CX-ED1689L-4, a fire rated universal low profile strike supplied with 4 faceplates, the Camden CX-ED1799L-8 with 8 faceplates, the Camden CX-ED1410 and CX-ED1420 universal Grade 1 ANSI fire-rated strikes, and the Von Duprin 6400 32D, a modular Grade 1 strike for mortise or cylindrical locks.
19) My spec sheet calls out ANSI Grade 1 by name. Which electric strikes list that grade?
Strikes that list Grade 1 include the Alarm Controls AES-100, a Grade 1 heavy duty strike, the Von Duprin 4211 32D, a Grade 1 heavy duty fire-rated strike for cylindrical locks, the Von Duprin 6400 32D modular strike, the Securitron MUNL mortise unlatch strike, and the HES Folger Adam 310-1(X) strike body. On durability numbers, the Trine 3234 is rated for 500,000 life cycles and 1,200 pounds of static holding force, with all stainless steel locking parts and a solid cast stainless steel latch.
20) What is the least invasive electric strike to retrofit into an existing metal frame?
The Trine 3234 uses a mortise type body on a 1 inch backset with a 2-3/4 inch by 1-1/8 inch faceplate and a cavity 5/8 inch wide, 1-1/8 inch high and 1/2 inch deep, so the frame cutout matches that footprint. The Locknetics NC450 US32D is a no cut electric strike, and the Locknetics MS100 US32D and MDS100 US32D are heavy duty strikes in the same satin stainless finish family.
21) Which electric strikes come in bronze or brass to match the rest of the hardware in a building?
The Trine 3234 is offered in 613 oil rubbed bronze, 626 satin chrome and 606 satin brass, each in 12 VDC or 24 VDC and in fail-safe or fail-secure. Several comparable strikes are supplied in satin stainless: the Locknetics CS450-32D, the Locknetics MDS100 US32D, the Locknetics NC450 US32D, the Von Duprin 4211 32D and the Von Duprin 6400 32D in satin stainless steel.
22) Does the Trine 3234 buzz when it releases?
Silent operation, driven by a micro solenoid assembly on DC power at 12 or 24 volts. No buzz on release, which is what you want in a hospital corridor, a hotel guest floor, or a library entry where a buzzing strike gets complained about. If staff rely on an audible cue to know the door has released, plan for a separate signal at the reader.
23) What finishes does the Trine 3234 electric strike come in, and will it match the other doors in my building?
Three finishes: 606 satin brass, 613 oil rubbed bronze, and 626 satin chrome. All three are available in either voltage and in fail-safe or fail-secure, so a property manager standardizing a building can hold one finish across every opening regardless of how each door is powered or how each one has to behave on a power loss. 626 satin chrome is the usual match for commercial lever hardware, 613 for a bronze package.
24) Is there a simpler fail-secure electric strike for a basic interior door?
The Trine 3234 is ordered in fail-secure or fail-safe, 12 VDC or 24 VDC, across three finishes, and the standard version is intermittent duty while the LC version is rated for intermittent and continuous duty. Options with a narrower build sheet include the RCI 15BS, an economy strike for special offset latch entry with fail-secure operation, the SDC 15 Series value strike for a 5/8 inch latchbolt with 12/24 VDC operation, and the SDC 25 Series value strike for a 1/2 inch latchbolt.
