Abstract: The aspects of the present invention relate to intelligent alarm systems and methods of using the intelligent alarm systems. In certain embodiments, the intelligent alarm system includes: one or more personal alarm devices, one for each user, and an intelligent alarm controller. Personal alarm device includes a transceiver module and a personal alarm module. Intelligent alarm controller includes a proximity detection module, a transceiver module, and an alarm control module. When at least one user carrying personal alarm device approaches the intelligent alarm controller within a predetermined distance range, the intelligent alarm controller detects the user using ultra-wide band (UWB) radio frequency signals, turns on a controller alarm device using alarm control module, and instructs the personal alarm device in the predetermined distance range via the transceiver module of the personal alarm device to turn on one or more alarms on the personal alarm device using the personal alarm module.
