4.3.3 SENTINEL SENTRY 110 & SENTINEL SENTRY 330 Annual Maintenance
Requirements
These gamma-ray source projectors must receive inspection and maintenance at least once a year.
The locking mechanism and outlet port mechanism must be removed from the gamma-ray source
projector and disassembled for proper cleaning, inspection and lubrication of components that are critical
to safety.
These procedures can only be performed on an empty gamma-ray source projector, which
requires transfer of the radioactive source assembly into an approved storage container.
The inspection and maintenance procedures must be performed by personnel specifically trained and
qualified for this work. QSA Global, Inc. service engineers will service these systems at one of their
service centers or in the field upon request.
