Introduction to the CDVI MVM Motorised Electric Deadbolt
CDVI MVM Motorised Deadboltis a compact, surface-mounted electric deadbolt designed for both indoor and outdoor access control installations. Engineered for robustness and reliability, it combines a motorised locking mechanism with a manual override, a non-handed design that fits left- or right-opening doors, and an IP57 rating for demanding environmental conditions. Supplied with a round cylinder and keys, the MVM is positioned as a retrofit-friendly solution for gates, heavy doors, cages and a wide range of controlled access points.

- Weight: approx. 1.25 kg
- Finish / material: Plated steel; varnished electronics
- Included items: Round cylinder, keys, manual override thumb turn
- High holding force (1,500 kg): This level of resistance makes the MVM suitable where physical security is paramount — perimeter gates, storage cages, and access points where forced entry must be resisted.
- Non-handed design: Eliminates the need to stock separate left- and right-handed units, reducing inventory complexity and simplifying on-site selection and installation.
- Surface mount package: Ideal for retrofit projects where cutting into door faces is undesirable or impossible. The rim lock style fits many existing installations with minimal modification.
- Outdoor-ready construction: Varnished electronics and nylon gears increase resistance to moisture and dust. The IP57 rating indicates strong protection against dust and temporary immersion — useful for exposed gates and exterior doors.
- Manual override: Provides peace of mind in the event of power loss — users can still operate the lock mechanically using the supplied cylinder and keys or the internal thumb turn.
- Flexible power options: Accepts 12 18 V AC or DC, making it compatible with a wide range of access control power supplies and installers existing systems.
Use Cases and Scenarios Where the MVM Excels
The CDVI MVM is suitable across a range of commercial, industrial and institutional applications. Here are typical scenarios where its attributes deliver strong value:
For gates exposed to weather, mud and dust, the IP57 rating and varnished electronics provide enhanced longevity compared with non-weatherproofed units. Its high holding force helps resist climatic or forced stresses on gates, and the audible alert on locking errors provides a clear indicator of problems that need attention.
In warehouses, gyms, or communal residential storage areas, the MVM offers a compact, surface-mounted lock that secures cages or rooms without requiring extensive door modifications. The included manual cylinder and keys support operational flexibility for managers and security staff.
Where doors are thick (40 60 mm) or of heavy construction and cutting for a mortice lock is impractical, the rim-style surface mount is an ideal solution. Installers can replace existing rim locks with minimal change to door structure.
With a 12 18 V power window and a NO/NC relay output, the MVM integrates readily with access control panels, intercoms and building management systems. Its modest inrush current helps when planning power budgets for systems with multiple locks.
Comparisons with Similar Products
When comparing the MVM to other locking technologies, it helps to weigh the typical trade-offs: strength vs. aesthetics, retrofit simplicity vs. flush fit, and outdoor readiness vs. indoor-only designs.
Mortice deadbolts offer a flush appearance and can be highly secure, but they require cutting into the door for installation. The MVMs surface-mounted rim design avoids that work, making it faster and often less expensive to install in retrofit situations. For sites where door integrity must not be compromised, or where installers prefer faster deployment, the MVM is typically the better choice.
Electric strikes are commonly used with access control for entry doors but depend on the existing latch or lock hardware and the door frame. The MVM provides a self-contained locking solution with its own deadbolt and very high holding force, which can be advantageous where frames are weak or where a standalone secure lock is preferred (e.g., gates, metal doors, storage cages).
Solenoid locks can be fast-acting and compact but sometimes trade off holding force and durability. The MVMs motorised mechanism with nylon gears and varnished electronics offers a balance of durability, torque and environmental resistance, and includes audible feedback on faults — features installers appreciate for reliability in heavy-use or exposed locations.
If an installation requires a completely flush aesthetic, a mortice solution may be preferable. Also, for extremely high-frequency access points requiring sub-second operation cycles, some solenoid solutions are quicker — however, they may not provide the same holding force or environmental protection as the MVM.
Customer Feedback and Installer Perspectives
Formal customer testimonials specific to this product were not provided here. However, based on the MVMs design and typical installer experience with similar CDVI motorised deadbolts, common feedback themes include:
- "Non-handed design reduces mistakes on site and simplifies stocking — a real time-saver for installers."
- "Surface mount retrofit is straightforward and avoids cutting doors, which customers appreciate on existing properties."
- "IP57 rating and varnished electronics give confidence for outdoor installs, especially on exposed gates."
- "The manual override and included cylinder/keys are practical for emergency or power-out situations."
These representative comments reflect the practical benefits installers and site managers often cite when specifying a robust, weatherproof rim-style deadbolt for access control projects. For project-specific references and reviews, consult installer forums or request case studies from suppliers.
Installation, Safety and Documentation
Installation is straightforward for qualified technicians. Key points to observe:
- Surface mount design allows easy replacement of existing rim locks; check the manufacturers dimensions for fixing and cut-out positions before drilling.
- Electrical input: 12 18 V AC/DC; plan wiring and fusing per local electrical regulations. Note inrush current of approximately 410 mA when sizing power supplies for multiple locks.
- Isolate power before wiring and follow the CDVI installation manual. Installation should be performed by a qualified installer or electrician.
