If you have been researching medical alerts, you may have run into the term personal emergency response system, or PERS. It sounds technical, but it describes something simple and familiar: a device that lets an older adult call for help at the press of a button. Healthcare providers, agencies, and researchers tend to use the term PERS, while most families call the same thing a medical alert. Here is what a PERS is and how it works.
Quick Answer
A personal emergency response system (PERS) is a device that lets an older adult call for help at the press of a button. It connects the user to a 24/7 monitoring center, where a trained response specialist can speak with them, send help, and stay on the line until it arrives. A PERS is also known as a medical alert system.
What Is a PERS, in Plain Terms?
A PERS has two parts: a help button the person wears, usually as a pendant or on the wrist, and a connection to a 24/7 monitoring center. When the button is pressed, it opens a two-way voice link to a trained response specialist who can talk with the person, understand what is happening, and send the right help. Personal emergency response system is simply the formal name for the medical alert devices many families already know.
How Does a Personal Emergency Response System Work?
Press the button and the system connects you to the monitoring center. A specialist speaks with you through the device, assesses the situation, and dispatches the help you need, whether that is a neighbor, a family member, or emergency services, then stays on the line until it arrives. In-home systems work through a base unit in the home, and mobile systems use built-in cellular and GPS so help can find you anywhere. There is nothing to dial and nothing to remember. For a closer look, see our guide to how a medical alert system actually works.
The Types of PERS
A personal emergency response system comes in a few forms. The right one depends on where the person spends their time and what they will comfortably wear.
| Type | Where it works | Best for |
|---|---|---|
| In-home PERS | Throughout the home and nearby yard, through a base unit | Time spent mostly at home |
| Mobile PERS | Anywhere there is cellular coverage, with built-in GPS | An active life outside the home |
| Wearable PERS | On the body as a pendant, wristband, or smartwatch | Those who want help always within reach |
Medical Alert offers each of these: the Home System for always-at-home protection, the Mobile System and Mini Mobile System for help on the go, and the Smartwatch for those who prefer the wrist.

What to Look For in a PERS
Features that matter in a personal emergency response system
- 24/7 monitoring by trained, U.S.-based response specialists
- Clear two-way voice so the person can speak with a specialist
- Water resistance, so it can be worn in the shower where many falls happen
- Long battery life and simple charging
- Reliable coverage, whether through a home base unit or cellular
- Optional automatic fall detection
- A comfortable design the person will actually wear
A note on fall detection
Automatic fall detection can sense a fall and connect the person to help even if they cannot press the button. One honest limit to keep in mind: no fall detection technology detects 100 percent of falls; always push your button when you need help.
Who Can Benefit from a PERS?
A personal emergency response system is a good fit for older adults who live alone, anyone who wants to keep aging in their own home, people recovering after a fall or a hospital stay, and those managing ongoing health conditions. For families, it is also peace of mind: a reliable way to know a loved one can reach help the moment they need it, even when you cannot be in the room.
Help should be one button press away, at home and on the go. See which Medical Alert system fits your life.
