Door Screening

Always detecting before, not beyond the door, Ferroguard Guardian is wall-mounted outside the MRI door in Zone III, rather than inside the doorframe like alternative ferromagnetic detection systems (FMDS). This means no detection gaps or sensor activation delays—even with outswing doors.

An FMDS mounted inside Zone IV is simply too late to meet ACR guidance to use FMDS for screening persons and devices approaching Zone IV. Choose Ferroguard Guardian and be confident that your FMDS will alert you in those crucial seconds that make the difference between incident and catastrophe.
