5.0 OPERATION PROCEDURES
5.1 General Description of Operation of SuiteSentry Single Screener
When SuiteSentry Single Screener is in operation, the device passively senses the magnet fringe
field of the specific environment it is placed in and “normalizes” to it. If an approaching object is
made of ferromagnetic material, the sensors in the vertical Sensor Array Column detect the
object’s ferromagnetic content, analyzes its ferromagnetic mass and threat potential and if it
exceeds the preset sensitivity threshold, the detector displays a visual alarm in the approximate
area of the offending ferromagnetic object as well as an audible alarm.
SuiteSentry Single Screener series detectors have three (3) distinct modes of
operation:
1. Standby Mode - Detector is passively scanning the ambient environment for threats or
ferromagnetic disturbance
2. Active Mode: Detector is now ready to scan – person is near enough to trigger the detector
from standby mode and now the Sensor Array Column is showing green LED’s
3. ALARM & LOCATION Mode – Detected object is above alarm threshold and is a projectile
threat in magnet room– Visual Location lights AND Audio Alarm

STANDBY Mode: No Green LED’s in Sensor Array Column, only the purple POWER ON
indicator in the top Display and nothing more. If a ferromagnetic object is brought in proximity
to the SuiteSentry Single Screener, an 8 segment blue LED light Ferromagnetic Disturbance
Level bar graph in the top display window will indicate the magnitude of the ferromagnetic
threat due to the approaching object. The more bar segments that are illuminated, the larger
the ferromagnetic disturbance is. The blue lights will indicate ferromagnetic material moving
near the detector even if the object or person has not come close enough to trigger the motion
detector and put the SuiteSentry Single Screener into the ACTIVE Mode.

ACTIVE Mode: will not be enabled until the object/person is within the adjustable “physical
presence” area, approx. 6-10” in front of the detector. As person moves in to the sensing area,
the PIR will detect your proximity and cause the system to automatically change into the
Ready-to-Scan or ACTIVE Mode and illuminate 6 green indicator lights in the Sensor Array
Column as long as motion is detected and for about 3 seconds after motion ceases.

ALARM & LOCATION Mode: If an object on the person is creating a magnetic disturbance
greater than the pre-set threshold , the system will then automatically change into the
ALARM Mode . The system will show the LOCATION of the offending ferromagnetic object on
the Sensor Array Column body through a series of 4 flashing Amber lights nearest to the
detected object. Additionally, the SuiteSentry Single Screener also displays the location in
the top bar graph with a flashing Amber light at the same relative height, allowing the
supervising screener to identify the area while standing back to observe the screening process
without causing alarms from the supervising screener’s personal attire. Refer to Figure 12 for
example.
The detected object(s) should then be removed.
The person should then be rescreened until no ferrous objects are detected by the SuiteSentry
Single Screener. Then the patient or staff can safely enter Zone III. Indicating the location of the
ferromagnetic object is vital. For example, if the bottom group of amber LEDs is activated, the
object is near the floor. There are 6 groups of 4 amber LOCATION indicator lights on the Sensor
Array Column with each group representing about 1 foot (30cm) of height. If multiple groups of
indicators are illuminated, a number of sensors have been activated, usually indicating a more
significant threat.

Nevertheless, if SuiteSentry Single Screener detector does NOT react/alarm, one should NOT
automatically assume that there are no ferromagnetic risks. Using this device is a
supplement to existing procedures.
WARNING!
This device has not yet been fully evaluated for its efficacy in detection of
ferromagnetic objects inside the body, such as IMPLANTS
