Electromagnetic Door Interlock Diagram

Electromagnetic door interlock systems reduce cross-contamination by ensuring specific doors never open simultaneously. The central control module connects to electronic maglocks, allowing up to 6 interlocking doorways. Maglocks engage with 600lb of holding force and can be easily disabled in case of an emergency.
