An emergency hailing device for use by elderly, physically challenged, addicted and medically at-risk users, particularly when living alone. The device periodically interrogates the at-risk user and in absence of a prompt response to the automatic interrogation signal cue, the at-risk user is presumed to need help and an emergency service or prearranged care-provider is automatically beckoned. The device may be worn or set near the at-risk user, available for immediate manual acknowledgment after the interrogation cue signal occurs. Failure to return a prompt response within a presettable time or response absence indicates that a problematic situation may exist and an emergency signal is activated assuring the at-risk user that help will be promptly hailed even if physical or mental incapacitation occurs. Emergency signal may include a bell or siren, a flashing-light to attract neighbors, or a predetermined telephone may be auto-dialed to hail a prearranged care-provider.
