This British Standard gives recommendations for the provision of lone worker
device (LWD) services. The standard is applicable to suppliers of LWD services,
either for their own operations or to customers. It gives the principles and
operational procedures to be implemented by an alarm receiving centre (ARC)
so that controllers can verify activation messages received from LWDs and assist
response services when reacting to requests for assistance from lone workers.
This standard is also intended to minimize the number of false alarms received
by response services.
