Alarmtech MC 240: Grade 2 Magnetic Contact For Recessed Mounting
The Alarmtech MC 240 is a heavy-duty, universal magnetic contact designed for high-reliability monitoring of doors and windows. Built with a robust aluminium-alloy housing shaped like a threaded screw, it is specifically engineered for easy recessed mounting into wood or plastic frames. Its superior build quality, featuring epoxy-sealed internals, makes it completely water-resistant (IP67) and suitable for both alarm and access control systems. While designed for recessed use, its extensive range of accessories allows it to be adapted for surface mounting or installation into high-security steel doors and garage entries.

Full Description
Heavy-Duty, Threaded Magnetic Contact for Seamless Security
The Alarmtech MC 240 is a professional-grade, universal magnetic contact designed for high-reliability monitoring of doors and windows. Engineered for recessed mounting, this contact is ideal for both alarm and access control systems where a discreet, tamper-resistant installation is required.
Constructed from a robust aluminium alloy, both the contact and magnet are shaped like threaded screws, making them exceptionally easy to install directly into wood or plastic. For more complex environments, the MC 240 is available with 6 or 10 meter length cable options (standard 2m), providing the flexibility needed for large-scale commercial or industrial projects.
Alarmtech MC 240 Key Features:
- Threaded Screw Design: The Al-alloy housing features a threaded exterior, allowing the unit to be screwed directly into pre-drilled holes for a secure, permanent fit without the need for additional adhesives.
- Grade 2 Security: Fully certified to EN 50131-2-6 Grade 2, ensuring it meets the rigorous standards required for modern residential and commercial security systems.
- Water-Resistant Construction: The contact part is sealed with a special epoxy, achieving an IP 67 rating. This makes it completely water-resistant and suitable for use in damp or outdoor-adjacent environments.
- Universal Application: While designed for wood and plastic, a wide range of accessories allows this contact to be used for surface mounting or installation in steel doors, safety valves, and garage doors.
- High Durability: Features a high-quality Alnico 5 magnet to prevent demagnetisation over time and ensure consistent “make/break” distances.

- Manufacturers Data Sheet
Benefits:
- Discreet Aesthetics: Recessed mounting hides the sensor within the door or window frame, maintaining the architectural look of the building while protecting the sensor from physical attack.
- Weatherproof Reliability: The IP 67 rating ensures the sensor won’t fail due to condensation or moisture ingress, common in external-facing doors.
- Installation Flexibility: The availability of long-run cables (up to 10 meters) eliminates the need for unsightly junction boxes near the opening.
- Robust Material: Unlike plastic contacts, the metal housing of the MC 240 resists cracking and environmental degradation.
Ideal Applications:
- High-End Residential: Discreet monitoring of wooden doors and windows.
- Commercial Offices: Integration with access control systems for door status monitoring.
- Industrial Sites: Monitoring safety valves or heavy-duty steel gates (when used with appropriate accessories).
- Harsh Environments: Areas prone to moisture or extreme temperature fluctuations.
The Alarmtech MC 240 combines the strength of metal construction with the precision of Grade 2 sensing. It is the definitive choice for installers who require a recessed contact that is as easy to install as it is difficult to bypass.
