3.3 Operational Siting Requirements-Performance
Since SuiteSentry Single Screener is designed to detect moving ferrous objects passing near or
approaching the Sensor Array Column, the selected site should be away from extraneous moving
objects such as printers, office chairs, and file cabinet drawers. Special hardware and software
design reduces the sensitivity to moving ferromagnetic objects on the sides and behind the Sensor
Array Column, but separation of movable ferromagnetic masses from the sides of the Detector
System is also desirable.
Maintain separation from electrical devices, especially those which contain transformers, electrical
motors or other moving parts as these devices create magnetic fields which can mimic moving
ferromagnetic objects. Distance should be maintained from electrically locked or electrically
opening doors. Some doors have magnets mounted on them to activate switches used to indicate
that the door is closed. Plan your installation to maintain separation from these doors and devices.
Summary of Operational Siting Requirements:

Remove electrical devices 9 feet (3 meters) away from the installed detector to prevent false
positive alarms.

Ensure area of installation is free from electrical and electromagnetic interference when
possible.

If electronic equipment is within 9 feet (3 meters) the detector may very well exhibit false
positives. Determine the object/device that causes this condition and remove from immediate
vicinity of the detector and allow the detector to stabilize to the environment.
3.4 Operational Considerations-Usage
The highest sensitivity to moving objects occurs within 3 inches of the Sensor Array Column. All
efforts should be made to minimize traffic in the area of the Sensor Array Column during the
screening process as this traffic may have ferromagnetic objects which can cause unintended
alarms.
The change from standby to active mode is determined by adjusting the Passive Infrared (PIR)
motion sensor located in the Top Control Panel display. Even small ferromagnetic objects on a
person or staff member that routinely enter the magnet room may trigger an alarm as these ferrous
objects will be magnetized by exposure to the MRI’s magnetic field. Once magnetized, some small
objects will cause an alarm identical to a larger-in-mass object. To minimize these alarms, staff
should be trained to minimize wearing of ferrous objects; such as, underwire bras, shoes with steel
shanks or springs, belt buckles, pens, badges, eyeglasses, and hair clips.
Summary of Operational Considerations:

Staff wearing ferrous material in their clothing will cause the detector to alarm. REMOVE all
clothing that exhibits alarms to ensure consistent screening results.

The detector will alarm for attire such as watches, belts, shoes, and underwire bras. If you feel
it pull at or near the bore, the detector will alarm on the object within several feet (5’) or more.

The SuiteSentry Single Screener is to be used only as a prescreening device.

All staff should acknowledge the detector alarms and not enter zone III if an alarm is displayed
until offending ferrous object is removed.
CAUTION!
The SuiteSentry Single Screener detector MUST be placed in area that has LESS
than a 2 Gauss field strength. Ensure that it is functionally capable of performing
in the preferred area of operation prior to permanent mounting!
