Home medical alert systems consist of a medical alarm pendant, medical alarm console (also called medical alert base unit), and monitoring center. The alarm pendant is worn around the neck, on wrist, or even on the belt and features a transmitter. On pressing the help button of the transmitter, the signal transmits to the console, which in turn passes through the telephone line. The signal then reaches the person at the medical monitoring center or a neighbor, depending on how the system is set up.
If connected to the monitoring center, the dispatcher immediately communicates with the person who pressed the button. The console has a loud speaker and a sensitive microphone for communication. The dispatcher determines the need of the user and acts accordingly. The monitoring center will charge a small monthly fee for this service.
Some of the models come with built-in accelerators, which automatically relay a distress signal. These models are useful in situations such as when people are incapacitated by a fall.
When home medical alert systems are set up for elderly persons, it is better to have a lockbox at the front door. These lock boxes are small and secure boxes with home keys inside. Hence, it is easier for the neighbor or a trusted person to enter the house and provide necessary help.
Home medical alert systems guarantee safety to disabled or senior citizens while providing them with a sense of independence. In general, these systems serve as emergency equipments and provide confidence and security to those individuals who lead a lonely life at homes.
