Alert1 Reviews

trust icons, alert1 medical alert systems

I fell on a walk and Alert1 got me the help I needed so fast. I didn't even need to push the pendant button before you were asking if I was OK. Thank you for saving me!

Fall Detection Protection On The Go

No phone? No problem. No base unit, cell phone, or landline phone is necessary with Kelsi Pro automatic fall detection systems.

Kelsi Pro uses a microphone and speaker to enable simple, 2-way communication to the Alert1 Command Center.

GPS, Wi-Fi, and cellular coverage is used in your mobile medical alert to find you if you don't know where you are.

Automatic fall detection technology senses falls and automatically notifies the Command Center.

Kelsi Pro is worn comfortably around the neck so you can take peace of mind with you on the go.

What Is Mobile Fall Detection?

Man Walking Dog mobile fall detection medical alert

Kelsi Pro provides mobile automatic fall detection. This GPS fall alert system contains sensors that are designed to differentiate between a fall and ordinary movements.

The mobile fall detection pendant is worn around your neck or clipped at the waist. If it senses a fall or you press the help button, you will be connected to a kind and compassionate US-based operator from an Alert1 Command Center.

*Does not detect 100% of falls - you should always press your button if you need help

What If I Don’t Know Where I Am?

Once you press your mobile help button, we use GPS, Wi-Fi, and cellular coverage to locate you. We then alert your emergency responders so they can come to your aid.

If your responders aren’t available, we will contact local 911 emergency services to help you. We stay on the line as you wait for emergency responders to help in your time of need.
