The Sentinel Pulse device works outside the home by using a cellular connection. ### What happens when the button is pressed?

Yes, with the optional GPS and geo-fencing add-on, for faster response and caregiver visibility. ### What is geo-fencing? Geo-fencing, part of the optional GPS add-on, alerts families and caregivers if a user leaves a safe area designated by the user. ### How long does the battery last if the power goes out? The Sentinel Pulse PERS device offers up to 77 hours of battery life when fully charged. ### What does the IP67 rating mean? IP67 means the device is protected from dust and temporary water immersion. It is water-resistant, not waterproof. ### Can family members be contacted first? Yes.

Sentinel Services offers longer battery life, optional fall detection and GPS safety tools, customized care plans, and U.S.-based support you can trust. ### Is there any delay in fall protection and how sensitive is it? With the optional Fall Detection add-on, the device raises an alert when it measures a fall or an impact above a set force. Fall detection is not 100% accurate and cannot detect every fall, so press the button whenever you need help. ### How approximate is the GPS location and how often does it update? With the optional GPS add-on, your Sentinel Pulse PERS device updates its location regularly. Accuracy depends on signal conditions. ### How can I wear the Sentinel Pulse PERS device?
