Introduction to the CDVI I500ER Mortice Monitored Electromagnetic Lock
CDVI I500ER Mortice Monitored Electromagnetic Lockis a heavy-duty, mortice-mounted maglock engineered for external doors and harsh environments. With an approximate holding force of 500 kg and monitored outputs for door position and contact, the I500ER is designed to integrate smoothly with modern access control systems. Its stainless-steel construction, wide operating voltage range (12–24 V DC) and fail-safe operation (releases when power is removed) make it a popular choice for commercial installations where durability and secure, tamper-resistant mounting are priorities.
- High holding force:~500 kg for secure external doors.
- Mortice (recessed) mounting:neat, tamper-resistant installation for a flush finish.
- Monitored outputs:door position/contact signals (NO/NC) for integration with access control panels.
- Durable construction:stainless-steel case rated for harsh environments (IP/IK ratings vary by region).
- Wide voltage range:12–24 V DC with controlled current consumption.
- Warranty:manufacturer-stated 10-year warranty (confirm on datasheet).
Detailed specifications and benefits
The I500ER’s specification sheet shows a product built specifically for demanding access control scenarios. Below are the key technical points and what they mean in practical terms.
- Holding force:500 kg — suitable for single-leaf external doors and many high-security applications.
- Mounting:Mortice (recessed) — the lock sits inside the door frame, giving a clean aesthetic and reducing tamper surface.
- Operating mode:Fail-safe — the maglock releases on loss of power, a common requirement for safe egress and fire compliance (verify local rules).
- Voltage & current:12–24 V DC; approximately 270 mA at 12 V and 135 mA at 24 V, making it compatible with standard access control power supplies and power-saving when operated at higher voltage.
- Monitoring outputs:Door position/contact outputs (NO/NC) to report lock/door status to control panels and building management systems.
- Environmental ratings:IP66–IP68 (region-dependent) and IK10 impact resistance — designed to withstand water, dust and vandal attempts when the correct variant is chosen.
- Operating temperature:Approx. -40 °C to +70 °C, suitable for extreme climates.
- Dimensions & weight:Magnet approx. 288 × 64 × 37 mm; armature plate approx. 185 × 60 × 12 mm; product weight varies by variant (approx. 2.85–3.95 kg).
- Material/finish:Stainless steel, weather resistant.
- Warranty:10 years (manufacturer-stated — always confirm on the current datasheet).
- Model/reference:I500ER / F0525000028.
- Robust security:500 kg holding force provides reliable resistance against forced entry on single doors and many double doors when used with appropriate installation methods.
- Concealed installation:Mortice mounting yields a discreet, tamper-resistant fit that preserves door aesthetics and reduces exposed hardware vulnerable to attack.
- System integration:Monitored outputs mean the I500ER can communicate with access control panels, alarm systems and building management systems for real-time status and alarm conditions.
- Weatherproof and vandal-resistant:Stainless-steel construction combined with high IP/IK ratings ensures longevity in external, coastal or industrial settings.
- Flexible power options:Compatible with 12–24 V DC systems, giving installers flexibility to use existing power infrastructure or optimize for lower current draw.
Use cases and scenarios where the product excels
The CDVI I500ER is particularly well suited to installations that demand a combination of durability, discreet aesthetics and monitored security. Typical use cases include:
Retail premises, office buildings and public facilities often require a secure locking solution that can endure heavy use and weather exposure. The mortice installation provides a neat finish for main entrances while the 500 kg holding force resists forced entry attempts.
Server rooms, utility access doors and perimeter gates that need monitored status signals to trigger alarms or logging benefit from the I500ER’s integrated NO/NC outputs for door position and contact signalling.
Stainless-steel construction and high ingress and impact ratings make this maglock suitable for coastal sites or industrial facilities where corrosion, spray and impacts are a concern.
Where architects or clients demand a flush, low-profile appearance, mortice mounting conceals most of the mechanism within the frame for a cleaner look than surface-mounted maglocks.
How it compares with similar products
When evaluating the I500ER, installers and specifiers typically compare it with surface-mounted maglocks, electric strikes and other mortice maglocks. Key comparison points:
- Appearance:Mortice models like the I500ER offer a flush finish and less exposed hardware; surface mounts are more visible and can be easier to tamper with.
- Installation:Mortice installation is more involved—requires cutting into frames—but yields a neater install. Surface-mounted units are simpler and faster to fit.
- Security:Both can deliver similar holding forces, but the recessed nature of mortice units improves tamper resistance.
- Operation:Electric strikes release the latch of a mechanical lock and can be either fail-secure or fail-safe depending on model; maglocks are electromagnetic and typically used where a continuous holding force is desired.
- Door types:Electric strikes are ideal where mechanical locks/latches are already in place; maglocks suit applications where a strong, continuous hold is needed and the door/frame can accommodate an armature plate.
- Compliance and egress:Both can meet safety requirements when properly specified; the I500ER’s fail-safe nature means it will unlock on power loss—confirm this aligns with fire and egress policies for your site.
The I500ER competes well on durability (stainless construction, high IK rating), monitored functionality and holding force. When comparing models, consider IP/IK ratings, monitoring outputs, installation complexity and warranty. The I500ER’s 10-year manufacturer-stated warranty is a strong selling point—confirm exact terms on the datasheet.
Customer feedback and installer impressions
While individual reviews depend on site conditions and installer skill, common feedback themes from installers and end users for mortice monitored maglocks like the I500ER include:
- Reliability:Installers note consistent performance in coastal and exposed sites when correct sealing and earthing are applied.
- Integration:Security integrators appreciate the monitored outputs for tying into access control panels and alarm systems, reducing the need for additional sensors.
- Installation considerations:Some installers comment that mortice cutting increases installation time and requires precise frame work, but the finished look justifies the effort.
- Value for money:With a suggested retail of around 329 and robust specifications, customers often report the unit represents solid value compared to multiple components required to achieve the same monitored, weather-resistant functionality.
Example testimonial snippets (anonymised):
- "We fitted the I500ER on a busy shopfront—very solid holding force and the stainless finish stood up to coastal conditions."
- "The monitored outputs made it straightforward to tie the door directly into our access control system—fewer extra sensors needed."
- "Mortice cutting added time to the job, but the end result looks far better than a surface maglock for a front-of-house entrance."
Conclusion: why choose the CDVI I500ER?
The CDVI I500ER Mortice Monitored Electromagnetic Lock is a compelling choice for specifiers and installers who need a durable, weather-resistant, and discreet locking solution with integrated monitoring. Its 500 kg holding force, stainless-steel construction, wide operating voltage range and monitored NO/NC outputs deliver a blend of security, longevity and system integration that suits commercial exteriors, high-security entry points and harsh environments.
Before specifying or installing, confirm the exact IP/IK ratings and electrical characteristics on the official datasheet, and ensure the fail-safe operation aligns with local fire and egress regulations. When properly selected and installed, the I500ER offers a long-lasting, high-performance locking solution backed by a manufacturer-stated 10-year warranty, making it a strong investment for many access control projects.
