What a Personal Emergency Response System Does
A personal emergency response system (PERS) is a device you wear or keep at home that connects you to a monitoring center when you press a button. You press the button, trained operators answer, listen to what happened, and send help — usually an ambulance or a family member — to your location. The system works 24 hours a day, and you do not have to speak clearly or be conscious for it to work; the monitoring center can dispatch emergency services based on your address alone.
The device itself is usually a wristband, pendant, or small box you keep on a table. It communicates with the monitoring center through a landline, cellular connection, or internet connection, depending on the system you choose. When you press the button, a two-way speaker activates so the operator can hear you and you can hear them. If you do not respond or say you need help, the center follows a protocol: they call your emergency contacts, then call 911 and send paramedics to your address.
PERS is not the same as a medical alert app on your phone. A phone app requires you to have your phone with you, unlock it, and open the app — steps that may be impossible if you have fallen or are confused. A PERS device works with one button press, even if you are unconscious or unable to speak.
Key Takeaways
- A PERS device connects you to a live operator 24 hours a day when you press a button, and the operator can send emergency services to your home without you speaking.
- Monthly costs range widely depending on whether you use a landline, cellular, or internet connection, and whether you add fall detection or other features.
- Wearable devices (pendants or wristbands) work best if you wear them consistently, and some systems offer waterproof versions for use in the shower.
- You will need to set up emergency contacts and give the monitoring center your address, medical history, and any medications you take.
- Some systems are monitored by the company that sells them; others use third-party monitoring centers, which can affect response time and how your information is handled.
Types of PERS Devices and How They Connect
PERS devices come in three main forms: wearable pendants or wristbands, stationary devices you keep on a table or nightstand, and mobile devices you can carry with you. Wearable devices are the most common because they stay with you if you fall in the bathroom or another room. Stationary devices work well if you spend most of your time in one place and do not want to wear something. Mobile devices are cellular-based and work outside your home, but they cost more and require you to carry them.
The connection method matters because it affects reliability and cost. Landline-based systems use your existing phone line and are the cheapest option, but they only work if you are home and near the phone jack. Cellular systems use a built-in cell signal and work anywhere, but they cost more and require a monthly cellular plan. Internet-based systems use your home WiFi and are often less expensive than cellular, but they stop working if your internet goes down or your power fails (unless the device has a backup battery).
Some devices add fall detection, a feature that automatically alerts the monitoring center if the device detects a sudden fall. Fall detection is useful if you are at risk of falling and might not be able to press the button, but it is not perfect — it can miss some falls and trigger false alarms. Fall detection typically adds $10 to $20 per month to your bill.
Monthly Costs and What They Cover
PERS monthly monitoring fees range from about $20 to $60 per month, depending on the system and features. Landline-based systems are usually the cheapest because they use your existing phone line. Cellular and internet-based systems cost more because the company maintains the connection. Some companies charge an upfront equipment fee of $50 to $200; others include the device free with a contract.
The monthly fee covers 24/7 monitoring by trained operators, not the device itself. If you cancel the service, you own the device but it no longer connects to the monitoring center. Some companies offer month-to-month plans with no contract, while others require a one- or two-year commitment. Canceling early on a contract may result in an early termination fee.
Additional features add to the cost. Medical alert jewelry (a bracelet or ring that identifies you as a PERS user) may cost extra. Some systems offer medication reminders, activity monitoring (which alerts a contact if you have not moved in a set time), or integration with smart home devices. Read the fine print to understand what is included in the base price and what costs extra.
Setting Up Your System and Emergency Contacts
When you sign up for PERS, the monitoring center will ask for your address, phone number, medical history, current medications, allergies, and the names and phone numbers of at least two emergency contacts. They will also ask whether you live alone, whether you have pets, and whether you have any mobility issues or conditions they should know about. This information helps the operator respond appropriately if you call for help.
You will receive training on how to use the device — usually a brief phone call or video showing you how to wear it, how to test it, and what to expect when you press the button. Most systems include a monthly test button so you can confirm the device is working without triggering a real emergency response. Some companies send a technician to your home to install the device and walk you through setup in person.
Your emergency contacts should be people who can reach your home quickly — a family member, neighbor, or friend who has a key. The monitoring center will call these contacts before calling 911, so they can check on you first if it is a minor issue. Make sure your contacts know they are listed and understand what to expect if the monitoring center calls.
Monitoring Center Differences and Response Time
Not all PERS companies operate their own monitoring centers. Some large companies (like Life Alert or Medical Guardian) monitor their own calls. Others contract with third-party monitoring centers that handle calls for multiple companies. This matters because it affects how quickly you get help and how your information is stored.
When you press the button, the monitoring center should answer within 30 to 45 seconds. The operator will ask if you need emergency services, and if you say yes or do not respond, they will dispatch 911 to your address. Response time from 911 depends on your location and how busy the local emergency services are — typically 5 to 15 minutes in urban areas, longer in rural areas. The PERS monitoring center does not send paramedics; they only call 911 on your behalf.
Ask the company whether their monitoring center is in the United States or overseas. Some companies use overseas call centers, which may have longer response times or language barriers. Ask whether the company stores your medical information on find servers and whether they share it with third parties. This information should be in their privacy policy, which you can request before signing up.
Common Mistakes and How to Avoid Them
The most common mistake is not wearing the device consistently. A pendant or wristband only works if it is on your body when you fall or have an emergency. Many seniors take off their PERS device at night, in the shower, or when they think they will not need it — and that is often when emergencies happen. Choose a device you are comfortable wearing all day, and consider a waterproof version if you want to wear it in the shower.
Another mistake is not testing the device regularly. Most systems include a monthly test button that lets you confirm the device is working without triggering a real emergency response. If you do not test it, you may not realize the battery is dead or the connection has failed until you actually need help. Set a calendar reminder to test your device on the same day each month.
A third mistake is not updating your emergency contacts or medical information when your situation changes. If you move, change your phone number, start taking a new medication, or your emergency contact moves away, tell the monitoring center right away. Outdated information can delay help or send paramedics to the wrong address.
Alternatives and When PERS May Not Be Right for You
PERS is not the only way to get emergency help. A smartphone with a medical alert app, a smartwatch with fall detection, or a straightforward phone call to 911 are all options. Medical alert apps are cheaper (often free or $5 to $15 per month) but require you to have your phone with you and be able to use it. Smartwatches with fall detection (like Apple Watch or Fitbit) cost $200 to $400 upfront but may be worth it if you already use a smartwatch.
PERS may not be right for you if you live with a family member or caregiver who is usually home, if you do not fall or have health emergencies often, or if you cannot afford the monthly cost. In those cases, a simpler solution like a phone with large buttons, a medical alert app, or a plan to check in with a family member by phone each day may be enough.
If you have cognitive decline or dementia, a PERS device with fall detection and activity monitoring may be more useful than a basic system, because you may not remember to press the button. Some systems designed for dementia include GPS tracking so family members can locate you if you wander. These systems cost more but may give you and your family more peace of mind.
Frequently Asked Questions
Do I need a landline to use PERS?
No. Landline-based systems require a landline, but cellular and internet-based systems do not. If you do not have a landline, choose a cellular or internet-based system. Cellular systems work anywhere but cost more. Internet-based systems are cheaper but only work at home if your WiFi is on.
What happens if I press the button by accident?
The monitoring center will answer and ask if you need help. If you say no or that it was an accident, they will end the call and not send emergency services. There is no charge for accidental button presses, and the center will not judge you. If you have frequent false alarms, ask about adjusting the button sensitivity or switching to a device with a two-step set up.
Will PERS work if I am unconscious or cannot speak?
Yes. If you do not respond when the operator calls, they will follow your pre-set protocol — usually calling your emergency contacts and then calling 911 to send paramedics to your address. The operator can hear background noise (like a fall or a cry for help) and will dispatch help based on that. Your address is enough for 911 to send an ambulance.
Can I use PERS if I travel or spend time away from home?
Landline and internet-based systems only work at home. If you travel, you need a cellular-based PERS device that works nationwide. Some cellular systems work in Canada and Mexico as well. Ask the company about coverage in the areas where you spend time, and confirm that the device will work in your car and in other buildings.
How do I know which company to choose?
Compare the monthly cost, the type of connection (landline, cellular, or internet), whether the company monitors its own calls or uses a third party, and whether the device is waterproof and comfortable to wear. Read reviews from other seniors, and ask whether the company offers a trial period so you can test the device before committing to a contract. Check whether the company is accredited by the Better Business Bureau or has complaints filed against it.
