Trine 323478LC Grade 1 Electric Strike Kit 12/24VAC/DC

The Trine 323478LC is a Grade 1, fail-secure electric strike kit from the 3000 Series, designed for cylindrical locksets and restricted door frame installations. Featuring a 1-inch total backset, stainless steel locking components, and a tested service life exceeding 500,000 cycles, it provides electrically controlled door release. The kit includes a 30LC mechanism and three interchangeable faceplates: 234-26D, 234X-375-26D, and 478-32D. Its compact design minimizes frame modifications while supporting compatible 12V and 24V AC/DC access control systems.

Trine 323478LC 3000 Series Grade 1 Fail-Secure Electric Strike Kit

The Trine 323478LC 3000 Series Electric Strike Kit provides electronically controlled entry for doors equipped with compatible cylindrical locksets. Designed for commercial offices, apartment buildings, storage rooms, and controlled-access entrances, the strike uses a fail-secure locking configuration that remains locked during a power interruption and releases the latch when electrical power is applied. The compact mechanism requires only a 1-inch total backset, making it suitable for hollow metal and wood door frames with limited installation clearance. Its stainless steel latch and locking components provide durability for repeated operation, while the mechanism is tested to ANSI/BHMA A156.31 Grade 1 performance requirements and rated for more than 500,000 operating cycles.

The 323478LC kit includes one 30LC electric strike mechanism and three interchangeable faceplates to accommodate different door frame preparations. The 234-26D faceplate measures 2-3/4 inches and features a satin chrome finish for compact ANSI-style installations. The 234X-375-26D faceplate also measures 2-3/4 inches but incorporates a 3/8-inch extended ramp for compatible Timely, Raco, Redi, and IDP door frames. The 478-32D faceplate measures 4-7/8 inches, features a satin stainless steel finish, and incorporates Trine's patented horizontal adjustment system for precise latch alignment. These configurations accommodate cylindrical latchbolts with up to a 5/8-inch throw, subject to door gap and installation requirements. Compared with conventional electric strikes, Trine specifies up to 60% less frame cutting with the 478 faceplate and 80% less with the 234 faceplate.

The Trine 30LC mechanism supports 12V and 24V AC/DC access control applications with electrical characteristics determined by the selected power source. For DC operation, the updated LC200 line conditioner regulates power during activation and reduces holding voltage for continuous-duty operation, helping limit heat buildup while providing surge and inductive kickback protection. The LC200 must be installed within 15 feet of the electric strike mechanism. Trine's current specifications require the LC200 for DC connections and direct wiring to the 30LC mechanism for AC applications. The strike provides silent operation with properly conditioned DC power, while direct AC operation produces an audible buzz and is rated for intermittent duty. Its electrically controlled release can be integrated with compatible card readers, keypads, access control panels, and remote release switches.

The 323478LC is designed to simplify new installations and electric strike retrofits by reducing the amount of material removed from the door frame. The modular faceplate arrangement allows installers to select the appropriate opening dimensions, while horizontal adjustment and available shims help establish proper latch engagement. The 3000 Series mechanism features a solid stainless steel latch, compact micro-solenoid assembly, and non-handed construction, supporting installation on compatible left-hand and right-hand doors. The strike is intended for protected interior applications and is not recommended for uncovered exterior doors. The standard 323478LC is not the fire-rated version; fire-rated openings require an appropriately listed alternative, such as the Trine 323478F-LC. The 478-CCFP competitor cutout filler plate is no longer included in the current 323478LC kit and must be obtained separately when required for a retrofit installation.
