Abstract
A method and system that allows individuals to transmit an alarm signal from a personal alarm device having a keypad, programmable register, a transmitter, and electrical power source. The keypad facilitates entry of a call-back telephone number into a programmable memory register and triggering the transmission of an alarm signal. The alarm signal is transmitted to a central alarm monitoring server that processes the alarm signal and initiates the necessary actions, including notifying relevant emergency response authorities and selectively contacting the individual at the call-back telephone number, if provided, or at a telephone number previously stored in a user preferences database in association with the user's account. The personal alarm device may have either normal and duress alarm buttons or have a keypad for entry of either a normal PIN code or a duress PIN code.
