Four alarm-system
01 July 2014
New to the UK, after establishing itself as a lone working market leader in North America, is the Loner SMD (Safety Monitoring Device), available from Castle Group.

The system is so customisable that it is said to accommodate even the most unique organisational structures, helping businesses deal with lone working issues once and for all.
The worker clips the device onto their waist and as soon as the device is switched on, the operator is safeguarded by four main alarms:
• Emergency Alarm – activated by pulling a cleverly designed latch avoiding accidental false alarms
• Silent Alarm – designed for hostile situations, a vibrating acknowledgement allows the operator to be assured help has been called for without alerting anyone in the surrounding area
• Man-down Alarm – the Loner SMD can distinguish falls from other activities that can be expected in some manual job roles
• No-motion Alarm – this sends a distress alarm when the operator hasn't moved for the pre-set timeframe.
The alerts are managed in a web-based portal, allowing access from any device, anywhere in the world.
