How Do Medical Alert Systems Work?

Medical alert systems are devices designed to provide peace of mind and security to seniors and individuals with medical conditions who live independently. These systems typically consist of a wearable device, such as a pendant or wristband, that can be activated in case of an emergency. When the device is activated, it sends a signal to a base unit, which then contacts a monitoring center staffed by trained professionals.

What is a Medical Alert System?

A medical alert system is a device worn on the body or placed in the home to provide immediate access to emergency services in case of an accident or medical emergency. Typically, these devices consist of a small, portable button or pendant worn around the neck or wrist.

When pressed, the button sends a signal to a base station connected to the user’s home phone line or cellular network. The base station then contacts a monitoring center, where trained operators can assess the situation and dispatch emergency services if necessary.


Medical alert systems provide a quick and easy way for users to call for help in an emergency. Beyond calling for help there are medical alert systems that call family.

Frequently Asked Questions

Do Medical Alert Systems Require a Landline?

In the past, most in-home medical alert systems required a landline phone connection to work. This was because the systems used a landline to communicate with the monitoring center in case of an emergency. However, with technological advances, many medical alert systems also offer cellular options.

These systems use cellular networks to communicate with the monitoring center, eliminating the need for a landline connection. Cellular medical alert systems can be a great option for those who don’t have a landline or who want the added security of a backup communication option in case their landline goes down.

Do Medical Alert Systems Require Wi-Fi?

Some mobile medical alert systems require Wi-Fi, while others use cellular networks. Wi-Fi-connected medical alert systems are typically designed for in-home use and rely on a Wi-Fi connection to communicate with the monitoring center. This means that the system will only work within the range of the Wi-Fi signal.

On the other hand, cellular medical alert systems don’t require Wi-Fi and can be used anywhere with cellular coverage. These systems are ideal for those who are frequently on the go or who don’t have a reliable Wi-Fi connection at home.

Can Medical Alert Systems Detect Falls?

Many medical alert systems offer fall detection features that automatically signal the monitoring center if a fall is detected. These systems use sensors to detect sudden movements or changes in position that may indicate a fall.

If a fall is detected, the system will automatically send an alert to the monitoring center, and help will be dispatched if needed. Fall detection can be especially useful for seniors who may be at a higher risk of falls or who may not be able to reach the help button in time.

Do Medical Alert Systems Work Outside of the Home?

Yes, many medical alert systems work outside the home as long as cellular coverage exists. Some systems come with a mobile device that can be taken with the user wherever they go, while others require the user to have a mobile phone.

It’s important to check with the provider to ensure that the system will work outside the home and in the specific areas where the user will be traveling.
