Popular Industry Terminologies Sneak Current - This is current that develops on the line through an outside source such as an electrical cross or grounding problem. The voltage level is not high enough to trip the standard 5-pin module so it stays on the line. It is usually too weak to cause immediate damage, but if unchecked could potentially create harmful heating effects destroying the voice/data system on the other side. Current Limiters - These are additional technologies included in 4-Series Modules that provide effective protection from Sneak Current Faults. Heat Coil - These devices employ a very high AWG element placed between the input and output side of the module. if a surge comes down the line it will melt the connection between the input and output, thereby protecting the equipment. Some heat coils have springs in them, so that when a surge breaks the circuit their tension is released permanently closing the line. These units are one-time use and will need to be replaced after each occurrence. PTC (Positive Temperature Coefficient) - This new state of the art self-resetting technology employs a carbon based alloy covered in a polymer connecting the input and output sides of the module. When an undesirable level of milliamps (heat) is reached, the unit will open the circuit not allowing anything to pass through to the CPU. When the issue is fixed the unit will cool down and automatically close the circuit. All of the Circa 4 Series Modules employ this vastly superior technology. Response Time - The time it takes for a module to redirect overvoltage current to ground. These times are measured in Nanoseconds (equal to one billionth of a second). Electricity travels at the speed of light or one foot per nanosecond. Test Points - Access points at the top of each module allowing a Test Points continuity test to ensure the unit is wired and working properly.
