Faraday Defense DEFCON EMP Alert System

Know when an EMP or CME-related electrical disturbance is occurringAn EMP or solar event may not be obvious until electronics begin failing. The DEFCON EMP Alert System monitors both ambient electromagnetic disturbances and power-line conditions, then provides distinct audible and visual warnings so you can take protective action such as opening the main breaker.Key features Detects E1/E2 high-frequency impulses and E3 line-voltage disturbances Monitors ambient air and power lines Three distinct audible alarm patterns for fast pulse, E3 overvoltage and E3 undervoltage conditions Red visual indicators when a detection occurs 85 dB alarm Hardened analog design with no digital electronics Plugs into a standard 120 V AC receptacle Draws less than 50 mA, roughly comparable to a 5 W nightlight Designed and manufactured in the USA This is an alert/detection device. It is intended to warn the user so additional protective action can be taken.
