The contractorSentry system comprises
of one or more transmitters, carried or worn by the contractor(s) which when activated, send an alarm signal back to the portable
receiver unit. The signal is then in turn transmitted out to pagers, or mobile phone using the autodialler.
The Lone worker transmitter can be carried in a pocket, or worn in the
carrying pouch (supplied). It features buttons, which allow a worker to call for help, and it also features a tilt switch,
which automatically triggers an alarm should the worker collapse, or be injured.
The pull-cord is a security feature, which may be clipped to a belt, and
should the unit be forcibly removed, an alarm will be triggered.
The portable receiver unit is a small carry case, which houses the electronics,
the battery with integrated mains charging system, and stores the portable pagers and lone worker transmitters, when
not in use.
Using a lead/acid battery, allows many rechargings of the battery itself,
and also allows it to be ‘topped up’ each night, by simply plugging in the mains plug into a mains supply.
