Popular Industry Terminologies 5-Pin Technology - This is the industry standard of Protection Modules. Each module protects one voice/ data line (pair). The first two pins are input Tip & Ring, the second two shorter pins are output to the Customer Premise Equipment (CPE) and the 5th pin is the ground for overvoltage. DC Voltage Break Over - The level at which a module is set to react and shunt overvoltage current to ground. Industry standard is 350v for Gas Tube Modules and 300v, 240v, 75v and 30v for Solid State Modules. 30 Gas Tube (Analog) - This technology has been around since the early 50’s. Being strictly a Life Safety Device the module is not set to redirect current until 350v hits the line. The gases in the module are set to react at 350v redirecting the surge to ground. Like the gases in a fluorescent light bulb this process can sometimes linger causing upwards of 650+ volts to enter the system. Circa does not recommend this type of module when sensitive voice/data equipment is involved. 3 Element Gas Tube/Balanced - These modules use a single gas tube for both Tip & Ring allowing both sides to simultaneously shunt to ground regardless of what side of the pair the current appears. 2 Element Gas Tube/Unbalanced - These modules utilize dual 2-element tubes, which create scenarios where one side of the device could ionize faster than the other leaving a path for the current to pass on through to the equipment. Solid State (Digital) - These modules employ a balanced Solid State Thyristor that is far superior to the Gas Tube Technology in speed of response and are virtually immune to overshoot, aging and failure due to repeated tripping within rated limits. Unlike the Gas Tube you can choose the amount of voltage you allow to pass through before they react. These modules come in Industry Standard 300v, 240v 75v & 30v Models.
