Detailed specifications and benefits
The C5S11’s specification package is optimised for straightforward access control installations while delivering monitored performance and reliable mechanical endurance. Key specification groups and the benefits they bring are summarised below.
- Model / Reference:C5S11 / E0605000005.
- Product type:Surface-mounted monitored electromagnetic lock — designed for interior use on conventional doors.
- Operation:Fail-safe — the lock releases on loss of power, allowing safe egress and compliance with many fire safety strategies (always confirm local codes).
- Supplied with:Armature plate, fixing kit and fitting instructions — reduces procurement complexity and speeds installation.
- Voltage:12–24 V DC — flexible for use with many access control power supplies and controllers.
- Current consumption:≈290 mA @ 12 V DC; ≈145 mA @ 24 V DC — low draw helps reduce transformer and wiring requirements and lowers running costs.
- Lock monitoring:1 relay (COM/NO/NC) & LED status indicator — enables integration with access control systems, security panels and building management for supervised lock state and diagnostics.
- Holding force:Up to 500 kg — more than adequate for most internal single-door security applications and many retrofit scenarios.
- Mounting:Surface (interior use) — rapid retrofitting without complex frame work or morticing.
- Dimensions and weight:Magnet ≈265–275 × 65–67 × 40 mm; armature ≈185 × 60 × 12 mm; weight ≈4.2 kg — compact, unobtrusive and manageable during installation.
- Operating temperature:−20 °C to +60 °C — suitable for a wide range of indoor environments.
- IP/IK ratings:IP42, IK10 — basic dust protection and good impact resistance for internal usage; not intended as a primary outdoor device without appropriate housing.
- Fire rating:EN1634-1 & EN1634-2 (30 minutes) with regional references to NFS 61-937 on some documents — check official CDVI datasheet and certificates for precise test scope and country acceptance.
- Documentation:Datasheet, installation manual and certificates are available from the CDVI product page. Installations should follow the manual and local building/fire regulations.
Use cases and scenarios where the C5S11 excels
The C5S11 is targeted at a range of commercial and institutional interior applications where monitored locking and fail-safe release are important. Typical use cases include:
- Office entrance and internal doors:Reception doors, meeting rooms and staff-only internal doors that require controlled access and the ability to integrate lock status into a building access system.
- Secure rooms and storage:Internal equipment rooms, IT closets or records rooms where a monitored lock helps ensure doors are closed and secured.
- Retrofit projects:Surface mounting and included fixings make the C5S11 well-suited to upgrading existing doors without extensive frame work or door replacement.
- Installer and trade supply:A cost-effective maglock for contractors who need a reliable, documented product to meet typical internal security specifications.
- Fire-safety sensitive areas:Where fail-safe operation is required to comply with egress and evacuation requirements — though installers must confirm local fire code acceptance and certificate applicability.
Comparisons with similar products in the market
When evaluating maglocks, common comparison points include holding force, monitoring capabilities, power consumption, robustness (IP/IK), fire certification, and cost. The CDVI C5S11 sits as an entry-level monitored 500 kg maglock. How it compares to other options:
- Versus higher-end or heavy-duty maglocks:Some maglocks offer greater holding forces (700 kg, 1600 kg, etc.), wider environmental ratings for outdoor use (higher IP rating), or extended fire test durations. Choose heavier-duty models if you need exterior weatherproofing, much higher shear strength, or longer certified fire performance.
- Versus basic, non-monitored maglocks:The C5S11’s built-in relay and LED monitoring give it an edge for systems requiring supervised locking. Non-monitored units may be cheaper, but won’t provide supervised feedback to access control panels.
- Versus alternative manufacturers:Brands vary on warranty, accessory ecosystems (mounting brackets, housings), and regional certification availability. CDVI offers a compact accessory set and documented fire tests; other brands may offer different bracket options or regional approvals — always compare certs for your market.
- Versus mechanical or electromechanical locks:Maglocks provide a smooth, maintenance-light solution with no mechanical moving parts in the magnet itself. For applications requiring fail-secure operation (remains locked on power loss) or mechanical key override, electromechanical or mechanical locks may be a better fit.
Customer feedback and installer notes
Public, platform-based customer reviews for specific industrial products like the CDVI C5S11 can be limited. Typical feedback observed from installers and trade customers for this class of product highlights the following points:
- Ease of installation:Installers appreciate the surface-mounted format, included armature and fixings, and compatibility with standard CDVI brackets which reduce site fabrication time.
- Reliable monitoring:The onboard relay and LED are often called out as useful features for quick diagnostics and integration with access control systems.
- Value for money:As an entry-level monitored maglock, the C5S11 is often viewed as a cost-effective option compared with more expensive heavy-duty models while still covering the needs of many interior applications.
- Documentation and certification:Installers recommend verifying the latest datasheet and certificates from CDVI prior to specifying, particularly for fire-rated doors or projects with strict regulatory requirements.
Conclusion — why choose the CDVI C5S11?
The CDVI C5S11 Surface Monitored Maglock offers a pragmatic balance of monitored functionality, 500 kg holding force and straightforward surface installation at a competitive price point (suggested price: 108.56 as provided). Its low power consumption, compact footprint and built-in relay monitoring make it especially well suited to internal access control projects, retrofit installations and installer trade supply where cost-efficiency and supervised locking are priorities.
Before specifying, confirm the required certificates for your jurisdiction (fire tests, CE/UKCA or local approvals) using the official CDVI documentation. For projects that demand higher environmental resistance, greater holding force, or fail-secure operation, consider alternative models or manufacturers; for most interior monitored locking needs, the C5S11 represents a practical and dependable choice.
