Trine 30LC Mechanism & LC100 - 11-28 AC/DC

The Trine 30LC is a compact, fail-secure electric strike mechanism designed for electronically controlled doors equipped with compatible cylindrical locks and deadlatches. Part of Trine's 3000 Series, it features ANSI/BHMA Grade 1 performance, over 1,500 lbs of static holding force, and a tested durability of more than 500,000 operating cycles. The mechanism accepts latchbolts with up to a 5/8-inch throw and requires only 1 inch of total backset. Its multi-voltage design supports 12/24V AC or DC applications, with an LC200 line conditioner required for continuous-duty DC operation. Interchangeable faceplates accommodate compatible wood, metal, and aluminum door frames.

Trine 30LC 3000 Series Grade 1 Fail-Secure Electric Strike Mechanism

The Trine 30LC Electric Strike Mechanism is a heavy-duty, compact electric door release designed for commercial access control systems using cylindrical locksets and compatible deadlatches. Manufactured by Trine Access Technology, the 30LC belongs to the 3000 Series of electric strikes, engineered to minimize door frame modifications while delivering reliable electronically controlled latch release. The mechanism features ANSI/BHMA A156.31 Grade 1 performance, over 1,500 pounds of static holding force, and a tested service life exceeding 500,000 operating cycles. Its standard fail-secure configuration keeps the door latched when electrical power is removed and releases the keeper when power is applied. Designed to accommodate latchbolts with up to a 5/8-inch throw, the 30LC supports commercial offices, apartment entrances, retail facilities, institutional buildings, and access-controlled interior doors where compact installation dimensions and dependable electric locking performance are required.

The Trine 30LC uses a stainless steel locking mechanism with a solid stainless steel keeper and precision electromagnetic release assembly. Its compact design requires only 1 inch of total backset, making it suitable for installations where conventional electric strikes require excessive frame preparation or available mounting depth is limited. The mechanism provides a 70 ft-lb dynamic force rating and accepts compatible cylindrical latchbolts and deadlatches within the manufacturer's specified dimensions. The 30LC is a fail-secure mechanism, meaning the strike remains locked when electrical power is interrupted while the mechanical lockset continues to provide its normal authorized operating functions. The corresponding Trine 30RS provides a fail-safe configuration for applications requiring the strike to release when power is removed. Mechanism spacers allow adjustment of the strike cavity depth by up to 1/8 inch, helping installers achieve proper latch engagement and alignment within compatible frame preparations.

The 30LC supports 12V and 24V AC/DC access control applications, with electrical operating characteristics determined by the selected power source and associated line conditioning equipment. For DC-powered installations, Trine specifies the LC200 line conditioner, which accommodates approximately 11-29 VDC input and conditions the electrical output for initial solenoid activation and reduced-power holding operation. This arrangement enables continuous-duty DC operation while providing surge and inductive kickback protection. Published DC electrical characteristics include 0.420A pull-in and 0.280A holding current at 12VDC, and 0.840A pull-in and 0.150A holding current at 24VDC, when used in the manufacturer's specified configuration. The LC200 must be installed within 15 feet of the electric strike mechanism. For AC installations, the manufacturer specifies direct low-voltage wiring to the 30LC mechanism without the LC200, with intermittent-duty operation and an audible buzzing sound during activation. The 30LC does not include a built-in access control reader or controller and requires appropriate external power and switching equipment.

The Trine 30LC features a modular electric strike design that supports interchangeable 3000 Series faceplates for different frame materials, lock types, and installation requirements. Compatible configurations include the 234 and 234X-375 faceplates for compact cylindrical lock installations, the 478 faceplate for standard ANSI-style preparations, and the 258 and 458 faceplates for compatible deadlatch and aluminum storefront applications. The Trine 323478LC kit combines the 30LC mechanism with selected cylindrical lock faceplates, while the 3258458LC kit includes faceplates designed for compatible aluminum frame and deadlatch installations. The mechanism itself is supplied separately from the complete faceplate kit, allowing installers to select the required mounting hardware for their specific application. Most 3000 Series configurations support non-handed installation, although certain 458 and 478 offset faceplates require attention to door handing and latch orientation. Proper installation requires verifying frame clearance, latchbolt projection, strike cavity alignment, and door closer adjustment to prevent excessive pressure against the electrically operated keeper.

The Trine 30LC is intended for commercial access control systems requiring compact, fail-secure electric latch release without replacing the existing compatible mechanical locking hardware. It can be integrated with appropriately rated keypad systems, card readers, intercom-controlled release circuits, access control panels, and remote door release switches, allowing authorized users to unlock the strike through an external electrical command. Compared with the Trine 3012 and 3024 fixed-voltage, intermittent-duty mechanisms, the 30LC supports multi-voltage operation and continuous-duty DC control when installed with the required LC200 line conditioner. The 30LC is particularly suited to retrofit applications involving restricted frame depth, including compatible wood, hollow metal, and aluminum door frames. The standard 30LC mechanism is not independently fire rated; fire-rated openings require an appropriately listed strike assembly and installation configuration. Trine does not recommend the 3000 Series for exterior door installations, and the operating temperature range specified in its installation literature is -4 F to 104 F (-20 C to 40 C). Installers must verify electrical duty cycle, line conditioner compatibility, latch engagement, mounting hardware, and applicable building and emergency egress requirements before placing the electric strike into service.
