Frequently Asked Questions

Q: What is a recessed door magnetic switch sensor and how does it work?

A: A recessed door magnetic switch sensor (such as the RC-33 / MC-33) is a two-part security device consisting of a Hall-effect magnetic sensor and a corresponding magnet. The sensor is installed flush into the door frame while the magnet sits in the door itself. When the door opens, the magnet moves away from the sensor, triggering the switching output and signalling your alarm or access control system that the door has been opened.

Q: What alarm or security systems is the RC-33 magnetic switch compatible with?

A: The RC-33 magnetic switch features a standard switching transducer output rated at 100V DC and 300mA, making it compatible with most wired home security alarm panels, access control systems, and DIY security setups that accept normally-open (NO) or normally-closed (NC) magnetic contact sensors. Always verify compatibility with your specific control panel before installation.

Q: Is installation of the recessed door magnetic switch difficult?

A: Installation is straightforward for anyone comfortable with basic DIY tasks. The sensor and magnet are designed to be recessed (flush-mounted) into pre-drilled holes in the door and frame, resulting in a clean, professional look. A drill, appropriate drill bit, and basic wiring knowledge are typically all that is needed.
