Trine 3250SOM-LC Series - The only electric strike for use with Dor-O-Matic, Includes LC 100, Aluminum and Dark Bronze Finish Face Plates

One part covers 12 and 24 volts, AC or DC, so you don't pick a voltage at the order form. Current draw runs 0.743/0.298 amps at 12VDC, 0.715/0.277 at 12AC, 0.397/0.170 at 24VDC and 0.378/0.173 at 24AC, all at 13.0 ohms. Every one of those is rated for intermittent or continuous duty, so you can run it continuously on a fail-secure setup without a separate part number. Operation is silent, and the lead wires are red.

Fail-secure. Drop power and the keeper stays locked, so the opening remains secure and free egress still comes from the exit device on the inside. If your application needs the opposite behavior, ZenSupply carries field-reversible fail safe/fail secure strikes such as the Hager 2925 and Hager 2928, where you set the mode during install. The 3250SOM is not reversible in that way.

No. The 3250SOM carries no fire rating, and a fail-secure strike on a labeled opening has to be a listed assembly. For a fire rated opening, ZenSupply stocks rated alternatives including the Von Duprin 6400, Grade 1 with a 3-hour UL 10C fail-secure rating for mortise or cylindrical locks, the Von Duprin 6210 for mortise locks, the Hager 2945 rim exit strike, and the Camden CX-ED1410/CX-ED1420 universal Grade 1 ANSI fire-rated strikes. None of those is a Dor-O-Matic solution, so on a labeled Dor-O-Matic opening you're changing the lock, not just the strike.

A universal strike with multiple faceplates is the right call when the lock is a standard cylindrical or mortise lockset, which is most openings. Dor-O-Matic hardware isn't one of those, and Trine positions the 3250SOM as the only solution for those locks. If your opening is a conventional cylindrical or mortise lock, look at a universal instead, ZenSupply carries the Camden CX-ED1689L-4 with four faceplates and the CX-ED1799L-8 with eight, and the Von Duprin 6400 modular strike covering mortise or cylindrical. Use the 3250SOM when the lock is actually Dor-O-Matic, or when you need the small vertical rod solution.

The Trine 3250SOM-LC is the solution for Dor-O-Matic locks, using the 3000 series mechanism in a compact body sized for vertical rod applications. It is a Grade 1 heavy duty, fail-secure strike rated for 500,000+ life cycles, and ships with both an aluminum and a dark bronze faceplate plus the LC100 surge and kickback protection module. Other heavy duty Grade 1 strikes such as the Alarm Controls AES-100 and the Von Duprin 4211 32D cover cylindrical lock openings rather than Dor-O-Matic hardware.

The 3250SOM-LC handles vertical rod openings with the 3000 series mechanism in a small body, and it is fail-secure with 12/24 VAC/DC operation. If the opening is a standard surface vertical rod device rather than Dor-O-Matic hardware, the HES Folger Adam 310-4-2 is a complete electric strike pac built specifically for surface vertical rods, Grade 1. Note the 310-4-2 is not fire rated, the same as the 3250SOM.

The 3250SOM-LC is a fail-secure strike. When the opening needs fail safe operation, or you want one part number that covers both, the Hager 2925 with a 5/8 inch latch, the Hager 2928, the Hager 2930, and the Hager 2945 rim exit strike are all field reversible fail safe or fail secure. The 2945 also carries a fire rating and a latchbolt monitor.

The 3250SOM-LC is built for Dor-O-Matic hardware and ships with aluminum and dark bronze faceplates. For a general aluminum storefront jamb with a narrow stile deadlatch, the Adams Rite 7100 Series is an electric strike for aluminum jambs with a flat 1-1/4 inch by 4-7/8 inch faceplate, and the Adams Rite 7160 covers aluminum jambs with the same 1-1/4 inch by 4-7/8 inch faceplate size. For hollow metal or wood jambs, the Adams Rite 7170 uses that faceplate size as well. None of the three carries a fire rating.

No, both faceplates ship in the box. You get one aluminum and one dark bronze powder coat plate, so the installer matches the jamb on site instead of the buyer guessing a finish at order time. That's useful on a fleet order where some storefronts are clear anodized and others are bronze, one part number covers both.

The LC100 is a surge and kickback protection module, and it comes with the strike. When the coil de-energizes it dumps the inductive spike that would otherwise come back down the wire into your access control board or relay. Because it's in the box, you don't need to source a separate diode or MOV for this strike, which is the part people forget and then blame the controller for.

It's a Grade 1 heavy duty strike rated past 500,000 life cycles, with a solid stainless steel latch and locking mechanism. That's the tier you want on a main entrance, a school corridor, or a multi-family lobby that cycles all day. Comparable Grade 1 heavy duty strikes ZenSupply carries include the Alarm Controls AES-100 and the Von Duprin 4211, though neither is a Dor-O-Matic solution.

Horizontal adjustment is built into the strike, so you can dial the keeper in and out to meet the latch instead of shimming the frame or re-prepping the jamb. On a retrofit where the existing door has settled or the closer has pulled it out of square, that adjustment is usually what saves the install.

The 3250SOM-LC is a commercial strike that is not outdoor rated. For a gate or other exterior opening, the Camden CX-ED1959 Series is an outdoor rated electric (gate) strike; it is not fire rated, so it suits a gate rather than a labeled door.

The 3250SOM-LC is a Grade 1 fail-secure strike with solid stainless steel latch and locking mechanism and the LC100 module for surge and kickback protection. When the access control system needs to see the latch state, the Dortronics 3300 Series is an electric strike with a latch bolt sensing switch running 12/24VDC with a strike plate for ANSI prep at 4-7/8 inch by 1-1/4 inch, the Hager 2945 rim exit strike includes a latchbolt monitor, and the Camden CX-ED1799L-8 is a dual monitor Grade 1 strike.

The 3250SOM-LC pairs with Dor-O-Matic vertical rod hardware. Several strikes in the same duty class are prepped for a specific latchbolt instead and will not serve that opening: the SDC 15 Series takes a 5/8 inch latchbolt at 12/24 VDC, the SDC 25 Series is for a 1/2 inch latchbolt, the SDC 30-4 is a rim mount strike for a 3/4 inch Pullman latchbolt, and the Adams Rite 7240 is a fire rated strike for cylindrical locksets with 5/8 inch latchbolt projection. The RCI 15BS is a fail-secure strike for a special offset latch entry. Confirm the latch the door actually carries before ordering any of them against a Dor-O-Matic device.

The 3250SOM-LC is the smallest 3000 series solution for vertical rods and offers horizontal adjustment to line the keeper up with the latch. If the frame will not take the prep at all, the Locknetics NC450 is a no cut electric strike, and the Camden CX-ED1689L-4 is a fire rated universal low profile strike shipping with four faceplates. The Camden CX-ED1799L-8 is a fire rated Grade 1 dual monitor strike supplied with eight faceplates when one part has to cover several different frame preps.

The 3250SOM-LC is Grade 1 heavy duty and fail-secure, built around Dor-O-Matic vertical rod hardware. For a mortise lock, the Securitron MUNL Mortise UnLatch is a Grade 1 fire rated strike, and the Von Duprin 6210 is a heavy duty Grade 1 fail-secure mortise strike at 24 VDC with a UL 10C fire rating. The Von Duprin 6400 32D is a Grade 1 modular strike that covers mortise or cylindrical locks in satin stainless steel.

The 3250SOM-LC operates on 12/24 VAC/DC, all four inputs at 13.0 ohms with silent operation and both intermittent and continuous duty. Comparables that also run dual voltage include the Dortronics 3300 Series at 12/24VDC, the SDC 15 Series at 12/24 VDC, the Hager 2930 at 12/24VDC, and the Von Duprin 4211 32D, which is field-selectable 12/24 VDC. The Von Duprin 6210 is 24 VDC only, so verify the power supply before swapping it in.

Commercial. It's a Grade 1 heavy duty strike with a stainless steel latch and mechanism, built for the cycle counts a commercial opening sees rather than a house door. Property managers standardizing on Dor-O-Matic storefront openings can spec the same part across the fleet since one number covers 12 and 24 volts, AC or DC, and both faceplate finishes.

No buzz. All four voltage configurations, 12AC, 12DC, 24AC and 24DC, are listed as silent operation. That matters on AC power, where a strike will normally hum, and on openings where you don't want the audible cue, a healthcare corridor or a hotel back-of-house door. If you want the buzz as a release signal for the person at the door, this isn't the strike that gives it to you.

The 3250SOM-LC is Grade 1 heavy duty and rated for 500,000+ life cycles, but it is matched to Dor-O-Matic hardware. Where the door carries other hardware, the Locknetics MDS100 US32D and MS100 US32D are both heavy duty electric strikes, and the Locknetics CS450-32D is part of the CS Series. Match the replacement to the latch and frame prep already in the opening.

The 3250SOM-LC addresses one Dor-O-Matic opening. For a double door, the Rockwood electric strike for double doors uses a 3/4 inch keeper and is Grade 1 and fire rated in the 310-1 Series. The HES Folger Adam 310-1(X) strike body accepts 1/2 inch, 5/8 inch, or 3/4 inch throw latchbolts and is Grade 1 and fire rated, which is useful when the two leaves carry different latch throws.

The 3250SOM-LC ships with the LC100 for surge and kickback protection plus two faceplates in aluminum and dark bronze finish. Among comparable strikes, the HES Folger Adam 310-4-2 is supplied as a complete electric strike pac for surface vertical rods, the Camden CX-ED1689L-4 includes four faceplates, and the Camden CX-ED1799L-8 includes eight. HES also catalogs separate accessory sets for the Grade 1 fire rated 1500 and 1600 Series strikes when parts are needed on their own.

No. The SDC 45F Series is a fire-rated electric strike built for a 5/8 inch latchbolt with a radius corner faceplate, which suits a hollow metal frame with a radius prep. The Trine 3250SOM-LC is fail-secure, not fire rated, and is the solution for Dor-O-Matic locks using the 3000 series mechanism in a vertical rod body. The two answer different openings, so the 45F should be specified where the frame and latch match it rather than as a Dor-O-Matic replacement.
