FerrAlert Halo II Plus - The Latest Advancement in Ferromagnetic Detection for MRI!

Safety FerrAlert™ Halo II Plus guards at the entrance into the MRI exam room, providing the most precise and reliable detection of medium to large ferromagnetic threats. FerrAlert™ Halo II Plus provides significant assistance in the prevention of serious injury to patients and staff or equipment damage. FerrAlert™ detectors are recognized to be the most accurate ferromagnetic detectors for MRI due to their exclusive location-specificity feature.


  • Proprietary AMR Sensor Technology used in FerrAlert™ detectors proven and independently tested to be most sensitive in "Real World" MRI environment due to its unique and patented sensor technology.
  • Raw sensitivity is only meaningful if you are in the ocean looking for an isolated ferromagnetic object ( e.g. submarine). In such environment there are few other ferromagnetic, moving objects to interfere with sensing. In the real environment of a hospital, where many ferromagnetic objects are moving all the time, you must be able to discriminate between "real" threats and objects that are ferromagnetic but not a threat.


  • The GREEN LED HALO array illuminated around the MRI entrance indicates that the detector is scanning and there are no ferromagnetic threats detected.
  • A YELLOW beacon light indicates that a threat is approaching the portal.
  • The RED LED HALO array flashes the entire portal, indicating a major threat such as a ventilator or oxygen cylinder approach the portal.
  • The greater the threat, the further away the pre-warning is activated.
  • Ferrous objects not approaching the entrance to Zone IV do not trigger an audible warning. A ferrous object is not a threat until it tries to enter the Magnet Room.


  • Pinpoints Location of the ferromagnetic threat allowing the Technologist to quickly and easily identify and remove it. NO invasive pat-down or hand-held detectors required.
  • Intelligent Visual Warning is triggered by approaching ferrous objects well outside the magnet room. The greater the threat, the further away the pre-warning is activated. Ferrous objects not approaching the entrance to Zone IV do not trigger a warning. Ferrous object is not a threat, until it tries to enter the Magnet Room. No irrelevant warnings.
  • Escalating Alarm Status is always visible from both inside and outside the magnet room thus giving the Technologist full control. ACR and The Joint Commission require control of Zone IV at all times.
  • Most Flexible Installation for all facility architectural layouts. Mounts unobtrusively with both in-swing and out-swing MRI room doors. Alarm Indicator Lights NOT blocked by out-swinging doors.
  • Patented Technology suppresses false alarms while providing the highest sensitivity to ferromagnetic threats. The use of 24 sensors and 18 detection zones ensures uniform sensitivity and detection reliability from head to toe.
  • Reduces Alarm Fatigue by not producing acoustic alarm on moving doors (in-swing and out-swing), exit from MRI room and cross traffic. Audio alarm is activated only at the threshold if advanced visual warning was ignored.
  • Ferromagnetic Incident Log Manager model F500 is available as an upgrade (sold separately). A Continuous and Automatic Visual Record of Potential and Actual Projectile Incidents.


  • Continuous Magnetic Disturbance Monitoring provides instant feedback via integrated and highly visible bar graphs
