D.L.S. is accredited to all the EMC procedures listed in the voting standard.
We all remember the fiasco of the 2000 presidential election when, because of some hanging chads, the tabulation of the votes for president was delayed. After the election the Federal Election Commission began encouraging voting districts to move toward electronic voting machines. Out of this move to electronic voting machines, a comprehensive standard was developed.

The EMC portion of the standard was essentially recommended by myself. I chose to use a similar process used in Europe for ITE equipment since it has worked so well over these past 22 plus years. D.L.S. is now accredited to these standards.

What does this mean to you?
We can help you meet those requirements here in the Chicago area, just 20 minutes from O'Hare International Airport.

Electromagnetic Compatibility
Electrical Power Disturbance

     e. Electric power increases of 7.5% and reductions of 12.5% of nominal specified power supply for a          period of up to four hours at each power level.

Electrical Fast Transient
Vote scanning and counting equipment for paper-based systems, and all DRE equipment, shall be able to withstand, without disruption of normal operation or loss of data, electrical fast transients of:
     a. 2 kV AC & DC external power lines;
     b. +1 kV all external wires >3m no control; and
     c. +2 kV all external wires control.

Lightning Surge
Vote scanning and counting equipment for paper-based systems, and all DRE equipment, shall be able to withstand, without disruption of normal operation or loss of data, surges of:
     a. +2 kV AC line to line;
     b. +2 kV AC line to earth;

Electrostatic Disruption
Vote scanning and counting equipment for paper-based systems, and all DRE equipment, shall be able to withstand ±15 kV air discharge and ±8 kV contact discharge without damage or loss of data. The equipment may reset or have momentary interruption so long as normal operation is resumed without human intervention or loss of data. Loss of data means votes that have been completed and confirmed to the voter.

Conducted RF Immunity
Vote scanning and counting equipment for paper-based systems, and all DRE equipment, shall be able to withstand, without disruption of normal operation or loss of data, conducted RF energy of:
     a. 10V AC & DC power; and
     b. 10V, 20 signal/control >3m.

Magnetic Fields Immunity
Vote scanning and counting equipment for paper-based systems, and all DRE equipment, shall be able to withstand, without disruption of normal operation or loss of data, AC magnetic fields of 30 A/m at 60 Hz.
