How does the lone worker alarm device work?
Incident
detection
Customisable alert criteria to best suit your operators and ensure reliable triggering without false alarms. Optional: SOS button functionality.
Escalation chains and
alarm verification
After incident detection, the LWP device sends notifications to the individuals in the escalation chain. Alarms are sent to computers or phones via our mobile lone worker app.
Location tracking for
faster response times
Once the alert is managed, supervisors locate the lone worker in distress to provide rapid assistance: the position is available on mobile phones or the web portal.

FAQ - Lone Worker Device
What is a lone worker device (LWD)?
A lone worker device is a system dedicated to the protection of lone workers. It enables the detection of incidents either manually (SOS button) or automatically (fall or immobility detection using sensors).
Is a lone worker device mandatory?
Equipping lone workers with LWP systems is not a legal obligation in itself. However, protecting lone workers is a mandatory requirement for the employer. Furthermore, case law highlights the necessity for employers to implement the protocols and systems required to protect lone workers in order to comply with regulations.
How to choose your lone worker protection system?
- Ergonomics and ease of use
- Available communication networks, dead zones
- Site size
- Presence of basements or indoor areas
- Specific standards related to site activities (ATEX, IP, etc.)
- Alert criteria
- Need for localisation in the event of an incident detection
- etc.
What is the price of a lone worker device?
The price of a lone worker device ranges from €50 to over €1,200 per year. The cost depends on several factors: mobile or fixed-site operators, site size, advanced features, ATEX certification, and specific IP ratings.
