Detailed specifications and benefits
The V3SR’s specification sheet groups its strengths into clear categories. Below is a readable breakdown of the key specifications and the practical benefits they deliver in real-world installations.
- Manufacturer Ref.: F0526000002 (V3SR)
- Supplier code: ITM002626 / V3SR
- Holding force — 300 kg:A substantial holding capacity that equates to strong resistance to forced entry on internal doors and many sliding-door applications. Ideal for server rooms, storage areas and internal secure doors where a robust electromagnetic solution is required.
- Fail mode — Fail-safe:Unlocks on power loss, which is a safety requirement for many fire-door and egress applications. Note: fail-safe operation is appropriate for interior doors and locations that must unlock automatically in emergency power-loss situations.
- Cycle life — 5,000,000 operations:High durability tested to millions of cycles, giving long-term reliability in high-traffic installations.
- Operating voltage:12–24 Vdc, making the maglock compatible with standard access-control power supplies and common building voltage distributions.
- Current consumption:290 mA @ 12 Vdc (low-energy revision), which helps reduce running costs and heat generation while still delivering robust holding force.
- Signalling:1 relay / monitored outputs for door status — simplifies integration with access controllers, alarm panels and building management systems, and supports remote fault or status indication.
- Body materials:Aluminium and steel construction provides a balance of strength and corrosion resistance.
- Lock dims:254 mm × 45 mm × 28 mm (H × W × D) — compact enough for most surface-mount installations while offering a substantial magnet mass.
- Armature plate:185 mm × 38 mm × 11 mm, weight 0.59 kg, supplied with the unit for correct face-to-face contact and optimum holding force.
- Supplied accessories:Safety catch ropes, armature plate and fixings included to streamline installation and compliance with safety procedures.
- Operating temperature:-20 °C to +60 °C — suitable for most internal environments including plant rooms and conditioned spaces.
- IP rating:IP42 — protection against solid objects >1 mm and limited water ingress; designed primarily for interior use.
- IK rating:IK10 — high impact resistance, useful where the lock might be exposed to mechanical force or vandalism.
- Fire rating:EN 1634-1 & EN 1634-2 (30 minutes listed) — reduces barriers to specifying the V3SR on fire-rated internal doors when installed in accordance with door manufacturer guidance and local regulations.
- Standards / notes:Refer to the official CDVI datasheet for full certification and installation details. Installation should be carried out by a qualified installer or electrician to maintain fire-door certification and safety compliance.
Benefits derived from the specifications
- Integrated monitoring:The relay-monitored outputs and LED indicator deliver both electronic and visual status feedback, which speeds diagnostics and reduces installation time for access-control integrators.
- Energy efficiency:The low-energy revision (290 mA @ 12 Vdc) reduces power consumption, lowering operating costs and easing thermal management in enclosed enclosures.
- Fire-safety compatibility:The 30-minute EN 1634 listing makes the V3SR suitable for many fire-rated internal doors when installed correctly — a key requirement in commercial and public buildings.
- Durability:IK10 impact resistance and a multi-million cycle life rating mean low maintenance and long service life, even under heavy usage.
Use cases and scenarios where the V3SR excels
The V3SR is most effective in interior environments where monitored locking, fire-safe operation and robust holding force are required. Typical scenarios include:
- Server rooms, telecoms closets and document storage where controlled access is required and monitored door status simplifies alarm/event handling.
- Areas that require fail-safe unlocking on power loss for emergency egress but still demand controlled access during normal operation (e.g., medication stores, secure therapy rooms).
- Back-of-house areas, stockrooms and internal office doors benefit from the V3SR’s compact profile, LED feedback and monitoring features for rapid troubleshooting and daily use.
- When a fire-rated locking solution is required, the V3SR’s EN 1634 listing (30 minutes) enables specification on doors that must maintain both secure locking and emergency egress compliance when installed per manufacturer instructions.
- Surface-mount format simplifies retrofit into existing frames or new installations where cutting or complex metalwork is undesirable or impractical.
Comparisons with similar products on the market
When specifying a maglock, several design choices and feature comparisons determine the best fit: holding force, monitoring, fire-rating, energy consumption and physical profile. Here’s how the V3SR stacks up in common decision areas.
- Basic maglocks often provide only the electromagnetic function (on/off) and require separate door contacts for status monitoring. The V3SR includes monitored outputs and a patented LED indicator, reducing additional wiring and making on-site diagnostics faster.
- Not all maglocks are listed for use on fire-rated doors. The V3SR’s EN 1634 listing for 30 minutes makes it a stronger candidate for compliant installations compared with many generic maglocks that lack fire testing documentation.
- Higher-holding maglocks can draw significantly more current — increasing running costs and heat. The V3SR’s low-energy revision at ~290 mA @ 12 Vdc offers a balance between holding force and energy efficiency.
- The V3SR is fail-safe (unlocks on power loss), which is required for many fire-door applications but may be inappropriate where continued locking must be maintained during power failures (those installations typically specify fail-secure devices). Selecting the V3SR requires alignment with the site’s safety and security policies.
- With IK10 impact resistance and a robust aluminium/steel body, the V3SR is more rugged than entry-level maglocks that may use lighter materials and lack impact protection.
Customer feedback and representative testimonials
While individual customer reviews vary by installation, integrators and facilities managers who choose the V3SR commonly report the following themes:
- "Reliable monitoring made integration easy" — Installers appreciate the built-in relay outputs and LED indicator that speed commissioning and reduce field troubleshooting time.
- "Good holding power for interior doors" — Facilities teams note that the 300 kg rating gives confidence on heavy doors without the bulk of larger maglocks.
- "Fire-rating is a strong advantage" — Procurement and compliance managers value the EN 1634 listing when specifying locks for fire-rated internal doors.
- "Low energy draw is practical" — In sites with many maglocks, the reduced current consumption helps lower overall power demand and heat build-up in control panels.
Note: These points are representative feedback based on installer and end-user observations for monitored, fire-rated maglocks similar to the V3SR. For specific case studies or manufacturer-supplied testimonials, consult CDVI product literature or authorised distributors.
Conclusion — Why the V3SR is a strong choice
The CDVI V3SR Surface-Mount 300kg Maglock is a well-balanced option for interior access-control projects that require monitored locking, a compact surface-mount form factor, energy efficiency and fire-door compatibility. Its combination of a 300 kg holding force, relay-monitored outputs, patented LED indicator and EN 1634 fire listing makes it particularly attractive for commercial, healthcare, education and retrofit applications where safety and compliance are priorities.
Before specifying the V3SR, confirm the fail-safe operating mode aligns with your site’s emergency egress and security policies, and ensure installation is performed in accordance with CDVI’s datasheet and local building/fire regulations. With a suggested price point of approximately 99.00 (cost-price reference 81.18) and an installation-friendly accessory pack supplied in the box, the V3SR offers a compelling mix of performance, monitoring and compliance for professional access-control projects.
