This model works on the buddy system principle. So the first thing you’ll need is a “buddy” or secure partner, who is willing to either provide or send for help in case of an emergency. If your buddy gets a secure partner system too, you can be their secure partner.
This kit includes one sonic alert base station, one wireless transmitter to be hung permanently in the bathroom, and a second transmitter to put in the bedroom within easy reach.
For this system to work, you give your secure partner (buddy) your sonic alert base station (that plugs into any wall outlet) and your secure partner can give you his if he also has a system.
This model (short range and lower cost) can transmit throughout the same floor as well as to one floor above or below. It can cover an area of up to four apartments when they are located in an apartment building or a condominium complex. It can even reach a nearby neighbor (private home).
