Flic Duo. Fall detection in a wearable button.
A dual-button SOS device for lone-worker deployments, built around accelerometer-based fall detection, real-time location sharing, and a three-year battery. Small enough to clip to a vest, explicit enough to trust when the wearer cannot reach a phone, and available with clip, lanyard holder, silicone sleeve, and custom-printing options for deployment fleets.

Fall Detection
Detect the fall, confirm the pattern, route the alert.
Flic Duo uses its accelerometer to identify the Low-G, High-G, and Stillness pattern of a possible fall. Server-side temporal algorithms confirm the event, the wearer gets a 10-second on-device cancel window, and a no-cancel event routes onward with accelerometer telemetry for the response team.
- verified Low-G + High-G + Stillness phases
- verified 10-second on-device cancel window
- verified 30 to 60 seconds from fall onset to dispatch
- verified Full accelerometer trace per event
- verified Evaluation Kits available for ARCs, GSOCs, and lone-worker platforms
SOS when the worker can push. Fall detection when they cannot.
Flic Duo is our recommended hardware for lone-worker deployments. SOS with real-time location sharing fires on a single push; hold-and-twist gives operators a discreet alert pattern without looking at the device. Fall detection covers the moment when the wearer is incapacitated or cannot reach the button.
- verified SOS with real-time location
- verified Hold-and-twist stealth alert
- verified Fall detection (Evaluation Kit available)
- verified Wearable: clip, lanyard holder, or pocket carry
- verified Silicone sleeve for weather protection
- verified White-label dispatch app + open API
Wear it, protect it, print it.
Flic Duo is designed for real deployments, not desk demos. The accessory set includes a clip, a lanyard holder, and a silicone sleeve for weather protection. The Duo can also be custom-printed for customer fleets and white-label services, just like Flic Smart Buttons.
- verified Clip for vest, belt, pocket, and equipment carry
- verified Lanyard holder for visible staff and lone-worker wear
- verified Silicone sleeve for outdoor and weather-exposed environments
- verified Custom printing for logos, alert symbols, and deployment IDs
Two buttons for clear, deliberate actions.
Beyond fall detection, Flic Duo gives operators two physical buttons plus tactile patterns such as push, double-push, hold, and hold-and-twist. The 3-color LED gives audio and visual feedback so teams know the alert registered.
- verified Two physical buttons
- verified Push, double-push, hold, and hold-and-twist
- verified 3-color LED with audio feedback
- verified Available in matte black or white
