Abstract: A device capable of being worn by a person includes a fall sensor responsive to the physical effect of a fall by a person wearing the device to generate a sensed-fall signal. A wireless transmitter can send a wireless alert signal in response to the sensed-fall signal without requiring participation by the person wearing the device. A base transmitter locatable on a premises where the device is to be worn can be enabled in response to the wireless alert signal to transmit a responder request to a remote responder. A two-way voice communicator separate from the wearable device can be located on the premises with the base transmitter. A remote responder can enable the two-way voice communicator for two-way voice communication with the person wearing the wearable device.
