A call button is a promise that someone will answer when your parent cannot reach a phone. The device matters less than the chain behind it. Before you pick a service, find out who picks up, who gets called next, and what happens when the system does not work the way the brochure says.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

Ask who answers, and when

Find out whether the monitoring center is staffed around the clock, where it is located, and whether the operators can see your parent's information during a call. Ask what they do when there is no answer from your parent: which contacts they call, in what order, and whether you can change that order. Ask whether they will call 911 and under what conditions. Write the answers down.

Test the reach

Press the button from every room your parent uses, including the bathroom, the hallway, the back step, and the bedroom at night. Check whether the base unit is close enough to the outlet and whether the button still works through a closed door. Ask the company how far the range is in an ordinary house and what can block the signal. Do the test yourself, not only once during setup.

Ask about automatic fall detection carefully

Some systems include motion sensors that try to detect a fall. Ask how the feature was tested, what it misses, how often it sends false alerts, and whether it can be turned off. Do not treat any automatic feature as the only safeguard. The button your parent presses is still the most reliable part of the system, so the press has to be easy for them to remember.

Check the battery and the charging routine

Ask how long the battery lasts, how the device warns about low power, and whether it needs a daily charge. Decide who checks the battery each week and what you will do if the warning comes at night. A dead pendant is the same as no pendant.

Read the fees and the cancellation terms

Look for the monthly fee, any equipment charge, the setup fee, and what happens if you cancel. Ask whether the contract auto-renews and how to end it in writing. Save the terms and the confirmation of cancellation, if you ever need them.

Put yourself on the call tree

Make sure your number is on the list, in the right order, and that the company has a second contact in case you do not answer. Give the service a short plain-language note about your parent's usual routine, their hearing, and the language they speak. For what to do when an emergency is happening right now, call your local emergency number first and then the monitoring service.
