A practical guide
Personal Emergency Response Systems
The fear that keeps adult children up at night is specific: mom falls, can't get to the phone, and lies on the floor for hours before anyone knows. A personal emergency response system — a PERS, or "medical alert" — exists to answer that exact fear. Press a button, and help is on the way.
They're genuinely valuable. They also have one well-known flaw families need to plan around. Here's the honest guide.
What a PERS actually is
At its core, a PERS is a button your parent can press to summon help. The button — a pendant, a wristband, or a clip — connects to either a base unit in the home or a small cellular device. Press it, and you reach a 24/7 monitoring center or it dials family directly. Newer systems add automatic fall detection, which calls for help even if the button is never pressed.
"PERS," "medical alert system," and "medical alert button" all mean the same thing.
The 4 choices to make
Choosing a system is really four smaller decisions stacked together.
1. In-home vs. mobile (GPS)
In-home systems work within range of a base unit — right for a mostly-homebound parent. Mobile/GPS systems work anywhere and can locate your parent if they fall away from home — right for a parent who still drives, walks, gardens, or goes out.
2. Monitored vs. unmonitored
Monitored systems connect to a professional 24/7 call center for a monthly fee — a trained operator talks to your parent and dispatches help. Unmonitored systems skip the monthly cost and simply dial programmed family numbers. Monitored is the safer default if no one is reliably available to answer at 3am.
3. Fall detection — yes or no
Automatic fall detection calls for help even when your parent can't press the button — important because in a serious fall they may be unconscious or disoriented. It usually adds a small monthly fee and isn't flawless, but for a parent with fall risk it's worth it.
4. What it costs & who pays
Equipment is often low-cost or free with a plan; monitored service runs a modest monthly fee, with fall detection and mobile/GPS adding a little more. Original Medicare generally does not cover PERS. Some Medicare Advantage plans include a medical-alert benefit, and some Medicaid HCBS waivers cover it — check the plan and ask the Area Agency on Aging before paying out of pocket.
The flaw: a button only works if they wear it
Here's what the sales pages don't lead with. A PERS only helps if your parent is wearing it and can press it. In practice, a lot of seniors leave the pendant on the nightstand — it feels like a label, an admission. And in a severe fall, your parent may be unconscious or unable to reach it.
Fall detection helps with the second problem but not the first, and it isn't perfect. The deeper issue is that a button is built for one moment — the acute emergency — and does nothing for the slower dangers: a parent who's stopped eating, growing confused, increasingly isolated, or who got up from a fall they should have reported.
Where Call Mabel fits
A PERS button and a daily check-in solve two different failure modes — and most families want both. The button handles the acute fall. Mabel handles everything around it:
- Nothing to wear or press — Mabel calls your parent's regular phone every day, so there's no device they have to remember
- Catches the slow problems a button can't — not eating, confusion, low mood, a fall they got up from
- Family alerts by text within minutes when your parent sounds distressed, hurt, or off
- Daily companionship on top of it all — the loneliness layer a button was never meant to touch
For many families the right setup is a monitored fall-detection button for the acute moment plus Mabel for daily presence and early warning. See how Mabel's safety net works without a wearable.

Frequently asked questions
What is a personal emergency response system?
A device — usually a wearable button plus a base unit or cellular unit — that lets a senior summon help fast in a fall or emergency. Pressing it connects them to a 24/7 monitoring center or dials family. Many add automatic fall detection. "PERS" and "medical alert system" mean the same thing.
Does Medicare pay for it?
Original Medicare generally does not. Some Medicare Advantage plans include a medical-alert benefit, and some Medicaid HCBS waivers cover PERS for eligible seniors. Check the plan and ask the Area Agency on Aging before paying out of pocket.
What's the biggest weakness?
The button only helps if your parent wears it and can press it — and many leave it on the nightstand or can't reach it in a serious fall. Fall detection helps but isn't perfect. Pairing the button with a daily check-in covers the slower problems a button can't.
