DEFCON™ EMP Alert System

What is the DEFCON™ EMP Alert System?

The DEFCON™ EMP Alert System is the first low-cost device designed to detect electrical disturbances resulting from an electromagnetic pulse (EMP) or a solar coronal mass ejection (CME). The DEFCON™ EMP Alert System plugs into any standard 120-volt AC receptacle and draws less than 50 milliamps of current, about the same as a 5-watt nightlight.

How does the DEFCON™ EMP Alert System detect E1, E2 and E3 of an EMP/CME?

E1 and E2 are detected by a very high-speed circuit capable of detecting electromagnetic disturbances as brief as nanoseconds in duration. E3 is detected by a circuit that continuously monitors the power lines.

How does DEFCON™ EMP Alert System warn of an EMP/CME?

The DEFCON™ EMP Alert System provides three distinct audible alarms:

• (1) a brief ‘beep’ when a very fast E1/E2-type pulse is detected

• (2) a long sustained ‘beeeeep’ when an E3 overvoltage condition is detected

• (3) a pulsating ‘beep-beep-beep’ when an E3-induced undervoltage condition is detected.

Red lights also become visible when any detection occurs.

Won’t I already know if an EMP/CME occurs?
