Medical alert systems compared, in plain English

The main types

• Home system. A button plus a base unit in the house. Good for someone who doesn't go out much.
• Mobile system. Works at home and out and about, using cellular and GPS, so help can find you.
• Monitored. The button reaches a 24/7 call center. There's a monthly fee.
• Unmonitored. The button calls family or friends on a list. Some can call emergency services if no one answers.
• Built into a phone. Some senior phones have a help button. Lively's Jitterbug phones have Urgent Response, which Lively says is available 24/7 on certain plans.

Questions to ask before you buy

1. Is it waterproof? AARP notes many falls happen in the bathroom.
2. Does it detect falls automatically, or must you press the button?
3. How long does the battery last, and does it warn when it's low?
4. Does it need a landline, and is there a battery backup if the power goes out?
5. Who runs the call center, is it open 24/7, and how fast do they answer?
6. What's the full cost? Ask for every fee: equipment, activation, monthly monitoring.
7. What's the cancellation policy? Look for a trial period and no penalty to cancel.
8. Test it in every room, and outside if they'll use it there.
