Product information

Description

Alarmtech KONTAKTRON CYLINDRYCZNY MC340 is a compact cylindrical magnetic contact (reed) sensor intended for monitoring doors and windows in wired security systems. The sensor detects changes in the magnetic field when an access point is opened or closed, providing a reliable input to alarm panels and control units. Its slim, cylindrical form factor allows installation in frames, casings, or other narrow mounting locations where a low-profile contact is required.

Advantages

The magnetic contact offers a simple normally-closed or normally-open switching behavior depending on installation and wiring, enabling straightforward integration with most wired alarm panels. Its cylindrical design reduces visual impact and can be recessed into frames for protection against tampering. The sensor is passive, requiring no internal power source, which simplifies maintenance and reduces lifecycle costs.

Suitable for

Monitoring residential doors and windows
Securing commercial access points and cabinets
Integration with wired alarm control panels and access control systems
Use in narrow or recessed mounting locations such as frames or profiles

Key specifications

Type: Cylindrical magnetic reed contact for doors and windows
Mounting: Recessed or surface in narrow profiles and frames
Connection: Wired contact suitable for alarm panel inputs
Power: Passive device (no internal battery required)
Compatibility: Designed for integration with standard wired security and access control systems

How to use

Install the cylindrical magnet and reed sensor so that the magnet aligns closely with the reed switch when the door or window is closed. Secure the sensor body in a recessed hole or on the frame using appropriate fasteners, and route the connection leads to the alarm panel input following the system wiring diagram. Configure the alarm panel to recognize the contact as normally-closed or normally-open according to the chosen wiring and desired behaviour. Test the contact by opening and closing the monitored access point and verifying the panel status changes accordingly.

Usage recommendations

Position the sensor and magnet with minimal gap for reliable operation and avoid mounting near strong external magnetic fields or large ferrous objects that could affect switching distance. Use suitable cable routing and strain relief to protect the leads, and verify compatibility with the alarm panel input specifications before finalizing installation.
