It’s powerful audio and vibration alarms, IP67 rating and 6 different alarm presets, completely configurable to your needs, makes this an ideal lone worker device for noisy & complex work environments. Use the ID card to; raise an alert in an emergency, set timers for added security and engage in two way communication to reassure & support your lone workers in the event of an incident.
Tailor to specific working positions.
The Twig SOS card is fully configurable; this means we can change the settings, features and functionality to meet your specific preferences. (E.g. the angle at which the tilt function is set at). This lone worker device can also be worn with a lanyard or belt clip – whichever is best for your lone workers and their job role. Wearing with a lanyard provides another way for an alert to be raised; via the rip alarm. When the lanyard is detached from the ID card an alarm will be raised automatically.
