Rutherford Controls (RCI) A71-05D 12VDC 7 Series Modular Insert Kit

The Rutherford Controls A71-05D is a 12 VDC, fail-secure modular electric strike insert designed for RCI 7 Series centerline electric strike assemblies. Manufactured by RCI, a dormakaba brand, this electrically unlocked strike insert provides controlled latch release for compatible cylindrical, centerline mortise, and exit device locksets. The A71-05D operates on continuous-duty 12 VDC power with a maximum current draw of 280 mA and maintains its locked condition when electrical power is removed. Part of the RCI 7 Series, it supports 500 lb static strength, 70 ft-lb dynamic strength, 250,000 operating cycles, and latchbolt projections up to 5/8 inch when incorporated into a properly installed compatible strike assembly. The non-handed modular design supports 1/8-inch horizontal keeper adjustment and a 1-1/2-inch frame cutout depth. Supplied with a lip bracket and installation hardware, the A71-05D requires a separately selected compatible faceplate. The RCI 7 Series is UL 1034 listed for burglary-resistant applications, making this insert suitable for commercial offices, retail entrances, educational facilities, and access-controlled door retrofits.

Rutherford Controls A71-05D 12VDC Fail-Secure 7 Series Modular Electric Strike Insert

The Rutherford Controls A71-05D is a commercial-duty modular electric strike insert designed for electrically controlled door locking applications. Manufactured by Rutherford Controls International (RCI), part of dormakaba, this model belongs to the RCI 7 Series Centerline electric strike family. The A71-05D is engineered to operate with compatible cylindrical locksets, centerline mortise locks, and selected exit devices, allowing authorized access through an electronically controlled strike mechanism. Its 12 VDC fail-secure configuration maintains the locked condition when electrical power is removed and releases the keeper when energized by a compatible access control system. The modular construction allows installers to select a suitable faceplate separately to match the door frame, making the A71-05D a versatile component for new installations, electric strike replacements, and access control retrofits in offices, retail facilities, schools, healthcare buildings, and other commercial properties.

The A71-05D utilizes a continuous-duty 12 VDC electromagnetic release mechanism with a maximum current draw of approximately 280 mA. Its fail-secure, or electrically unlocked, operation means the strike remains mechanically secured during a loss of power and releases when the electric strike coil is energized. This design helps maintain controlled entry during power interruptions while allowing mechanical egress through an appropriately configured lockset. The manufacturer specifies a nominal coil resistance of approximately 43 ohms at 25 C (77 F), with the 12 VDC model designed for quiet operation compared with the audible buzzing of AC-powered strike configurations. Electrical connections are made through the strike's terminal screws, and the coil is not polarity-sensitive under normal wiring conditions. Where a suppression diode is required by the access control equipment, installers must observe the diode's specified polarity and installation requirements. The A71-05D can be integrated with compatible access control panels, card readers, keypads, relays, and regulated 12 VDC power supplies.

The Rutherford Controls A71-05D is part of an electric strike platform engineered to provide 500 pounds of static holding strength and 70 foot-pounds of dynamic strength in a properly assembled and installed configuration. The RCI 7 Series is designed for a mechanical endurance rating of 250,000 operating cycles, supporting frequent daily use in commercial environments. Its strike mechanism accommodates latchbolt projections up to 5/8 inch (16 mm) and incorporates a horizontally adjustable keeper arrangement that permits approximately 1/8 inch (3.2 mm) of adjustment for proper latch alignment. The enlarged latch cavity supports compatible cylindrical, aluminum storefront, and centerline mortise locking hardware, including selected three-piece antifriction latch designs. A vibration-resistant keeper design helps reduce susceptibility to unauthorized manipulation through door or frame vibration. Correct latchbolt engagement, door clearances, and strike alignment are essential for maintaining the intended locking performance.

The A71-05D features a modular strike insert construction designed for a 1-1/2-inch-deep (38 mm) frame preparation. The RCI 7 Series supports compatible door thicknesses ranging from 1-3/8 inches to 2-3/8 inches (35 to 60 mm), depending on the lockset, frame geometry, and selected faceplate. The A71-05D is supplied as a modular electric strike assembly without a finished faceplate, allowing installers to select from compatible RCI 7 Series faceplate profiles for aluminum, hollow metal, and wood frame applications. Its non-handed construction supports both right-hand and left-hand door installations without requiring a different strike insert. The modular package includes the strike insert, lip bracket, trim plate, and associated installation hardware. The trim plate can help conceal irregularities around an existing frame cutout during retrofit installations. A compatible faceplate must be ordered separately to complete the installation.

Installation of the Rutherford Controls A71-05D requires selecting the appropriate RCI 7 Series faceplate and preparing the door frame according to the manufacturer's dimensional drawings. Compatible modular faceplates accommodate a variety of commercial door frame configurations, including aluminum storefront and conventional metal or wood frames. Installers must establish the correct horizontal and vertical latch centerlines, secure the insert to the lip bracket, attach the selected faceplate, and connect the strike to a suitable power supply. For cylindrical locksets, the latch centerline must align with the center of the strike opening; for mortise locks, the lip bracket ramps must be positioned correctly relative to the deadlocking trigger. The manufacturer also offers optional lip bracket extensions, mounting templates, and frame preparation accessories for installations involving deep frame reveals or replacement of existing strike hardware. Proper installation ensures that the latch can engage and release freely without binding or interfering with the lockset's deadlocking function.

The Rutherford Controls A71-05D is designed for use within the RCI 7 Series electric strike family, which is UL 1034 listed for burglary-resistant electric locking applications. The manufacturer's published specifications identify 500 lb static strength, 70 ft-lb dynamic resistance, non-handed installation, 250,000 operating cycles, and adjustable keeper positioning as key performance characteristics of the series. The modular strike design supports professional electronic access control installations where reliable electrically controlled entry must be combined with existing mechanical door hardware. Appropriate lockset compatibility, frame preparation, power supply sizing, and code-compliant egress arrangements must be verified before installation. The current RCI 7 Series manufacturer product page identifies a five-year limited warranty, while some older distributor literature specifies three years; applicable warranty terms should be confirmed for the supplied product. With its 12 VDC continuous-duty operation, fail-secure locking function, modular faceplate compatibility, and durable centerline strike construction, the A71-05D provides a practical electric strike component for commercial access control system upgrades and replacements.
