Description
Reliable Electric Locking for Commercial Timber and Steel Entrances
Managing traffic through busy commercial entrances requires a balance between seamless accessibility and dependable perimeter protection. In many public buildings, offices, and educational facilities, external doors undergo thousands of cycles every week. Traditional mechanical latching hardware often struggles under heavy footfall, leading to wear, alignment drift, and compromised perimeter security. When security managers need remote latch release connected to modern access control systems, selecting a dependable strike mechanism becomes essential.
The Adams Rite 7140-310-628 Electric Release Timber/Steel Door 12V Dc provides an industry proven solution designed specifically for modern metal and solid timber frames. Manufactured to interface directly with deadlatches such as the Adams Rite 4700 series, this electric strike replaces standard physical strike plates to provide remote unlocking capabilities. Operating smoothly on 12V DC power, it allows facilities teams to link their entry systems directly to keypad readers, proximity sensors, or intercom push-buttons without sacrificing mechanical structural integrity.
Featuring an architectural satin aluminium finish, this model combines a discrete aesthetic profile with solid internal mechanics. Whether you are upgrading an existing entrance during an access control retrofit or specifying a new build, this strike ensures smooth release action under regular use while maintaining the physical resistance required to protect assets and staff inside your premises.
Core Operational Features and Engineering Advantages
Electric strikes are the mechanical heart of remote access systems. The internal geometry of the Adams Rite 7140 series has been developed to deliver consistent latch release without excessive friction or binding, ensuring positive latch engagement whenever the door swings shut.
Engineered for Steel and Timber Frameworks
The faceplate geometry is configured to install flush into hollow steel posts or prepared hardwood jambs. This clean profile minimises visible disruption to the frame and maintains the architectural lines of modern commercial entrance systems.
Continuous Duty 12V DC Operation
Operating on standard 12-volt direct current power, this strike integrates seamlessly with mainstream commercial power supplies and access control control boards. The electrical coils are designed for steady low power draw and reliable latch actuation.
Durable Satin Aluminium 628 Finish
The clear anodised 628 finish delivers high resistance to atmospheric corrosion and regular handling. It blends cleanly with standard architectural aluminium door furniture, ensuring a cohesive look across corporate and public entries.
Dependable Latch Jaw Retention
The hardened release jaw retains deadlatches firmly when locked. Upon receiving an electrical signal, the jaw pivots open freely, allowing authorised users to push or pull the door open with minimal manual effort.
Installation and Integration Pipeline
Integrating the Adams Rite 7140-310-628 Electric Release Timber/Steel Door 12V Dc into commercial doors requires precise site preparation to achieve smooth operation and complete security.
Step 1 Frame Preparation
Measure and cut the mortice recess within the frame jamb using the supplied manufacturer template. Ensure proper depth clearance for internal electronics and rear wiring runs.
Step 2 Wiring Connection
Route standard low voltage cables through the frame cavity. Terminate the conductors cleanly to the strike terminals, verifying correct 12V DC polarity before seating the unit.
Step 3 Latch Alignment
Hang and close the door leaf to check latch bolt entry. The deadlatch bolt must fully drop into the strike jaw without pre load friction against the pivoting release mechanism.
Step 4 Commissioning
Secure faceplate fixings and trigger the access controller. Test multiple release and relatch cycles to ensure immediate jaw unlocking and silent reset on closure.

Practical Installation Considerations
When fitting the Adams Rite 7140 electric strike, alignment between the deadlatch and the strike jaw is critical. If the door leaf rests under tension against the strike jaw, often called door pre load, the internal release solenoid can struggle to pull clear under standard power. Ensuring that door closers are adjusted properly and that perimeter seals do not force the door leaf against the strike will ensure long service life and reliable release on every cycle.
For timber frames, carpenters should ensure the mortice pocket provides ample room for the back body without forcing wires against sharp edges. In steel frames, using dedicated fixing tabs or mounting brackets provides firm anchoring against door slams. Connecting a surge protection diode across the DC terminals is good practice to prevent back electromotive force from damaging sensitive access controllers.
