We use the DMC 2000 ped and have experienced spurious alarms for the following reasons:
- Welding - during welding process, became too close to components and alarmed due to frequency.
- Battery issues - battery compartment became damaged or cover not installed correctly
- iPam - ped incorrectly installed
- Security - ped alarm due to armory door sensor - frequency
- cell phone - again frequency,
- check other components or RF equipment being used in area.

Subject: Powernet: Invalid EPD Dose Rate Alarms
Sent by: [email protected]
Duke Energy Progress-Brunswick site is experiencing a higher than usual occurrence of invalid EPD dose rate alarms, using the DMC2000. Other than the human performance factor (dropping, bumping etc), does anyone have any information concerning any configuration/ operational issues with the EPD proper that may be a contributor to spurious rate alarms?
Thank you for your time
