A low side surge is when the surge actually comes into the equipment via the ground, commonly as a result of a nearby lightning strike dissipating into the earth. When lightning strikes the earth, the millions of volts do not just "disappear' " The volts are dissipated (discharged) into the earth -- the same earth that your equipment is connected to via the wiring.

Model ILD-PB Questions & Answers

What is an Intelligent Line Disconnect®???

The ILD is an active and automatic Equipment Protection System that has the same effect as when you PULL THE AC PLUG from the wall outlet, DISCONNECT COAX and/or PHONE LINES from your electronic equipment when it is not in use and turned off. This means that not only are your 1/0 lines disconnected from the external wiring, but they are also connected and shunted together and to a common ground. With conventional surge suppressors, your equipment remains connected to the power source, coax, and telephone lines even when your equipment is turned off or not in use.

The ILD provides absolute security from hackers or unauthorized users when your computer is not in use. Your private and valuable information is totally disconnected and isolated from intruders, hackers, etc.

Questions & Answers about the Intelligent Line Disconnect®

Q. What is an ILD? What does it do that conventional surge suppressors don't do?

A. The ILD is an ACTIVE & AUTOMATIC Equipment Protection System that has the same effect as when you PULL when it is not in use and turned off. This means that, not only are your equipment inputs and outputsTHE AC PLUG from the wall outlet, and/or DISCONNECT COAX and TELEPHONE LINES from your electronics when it is not in use and turned off. This means that, not only are your equipment inputs and outputs disconnected from the external wiring, (which is the path surge voltages take to damage equipment but the inputa and outputs are also connected or shunted together and to a common ground. This action combats the potentially damaging low side surge. With conventional surge suppressor protection devices, your equipment remains connected to the power source, coax, and telephone wiring even when your equipment is turned off or not in use.

Q. What is a low side surge? How is equipment damaged from it? What is the best protection from it?

A. A low side surge is when the surge actually comes into the equipment via the ground, commonly as a result of a nearby lightning strike dissipating into the earth. When lightning strikes the earth, the millions of volts do not just "disappear' " The volts are dissipated (discharged) into the earth -- the same earth that your equipment is connected to via the wiring. Because a surge suppressor is a passive (remains connected) and ground referenced device, it will pass an over-voltage (surge) in either direction. In the case of the low side surge, a surge suppressor can pass the surge from the power (or phone line) to ground, or from ground into the power (and/or phone line) and straight into your equipment. This is why a great deal of equipment is damaged even though it was connected to an ordinary surge suppressor. Equipment can also be damaged from a low side surge if there is more than one "ground" connected to the equipment, (such as the electrical ground from the power cord and an external ground like a ground rod,) and the grounds are not tied together to form a "common ground." It has long been said (and proven) that the surest way to protect equipment is to disconnect all wiring and unplug it. That is exactly what the ILD does, automatically, when you are not using your equipment. It must be clearly understood that when you are through using your equipment or a storm approaches, you must power down and turn off your equipment in order for the Intelligent Line Disconnect® to protect it.

Q. Why do I need an ILD when I have a UPS with my computer/modem?

A. Even with a UPS, your equipment is still electronically connected to the AC power, which means that there is still a potential for a damaging surge from lightning to go through the lines to your equipment. The ILD isolates your equipment from that electrical potential.

Q. How do I operate the ILD What exactly does it do? How do I know it's working?

A. When you want to use your computer, first you turn on the power switch on the UPS and then press the pushbutton on the front of the ILD unit. A RED LED (equipment "Connected" indicator) comes on indicating that the telephone line is connected to your Modem, coax cable connections are made (if you are on a network) and that AC power (from the UPS) is now connected to all of your equipment (computer, monitor, printer). Next, turn on your equipment as you always have, and the GREEN LED (equipment "Disconnected" indicator) is no longer illuminated. That's all there is to it. You just use your equipment as you always have. When you are finished and turn off all of your equipment (either individually or with the one switch on the Multiple outlet strip,) the ILD senses that you have turned everything off, and AUTOMATICALLY DISCONNECTS the Modem, coax, and AC inputs to all of your equipment and grounds them, until you want to use the equipment again. To indicate that the equipment is protected, the GREEN LED illuminates indicating "DISCONNECTED", and the RED LED goes out. It's that simple, that safe.

Q. Does the ILD have any built-in safe guards or fail safe features?

A. Yes, the ILD Protection System has a built-in SAFE GUARD. Say you push the button on the ILD unit but you get a phone call, and don't turn on your equipment within about 30 seconds. The ILD Protection System will AUTOMATICALLY DISCONNECT all your equipment inputs, and revert to the protected mode. This is so you don't get distracted and accidentally leave your equipment on to get "fried". In addition, the ILD has a fail safe. If, for instance, you have your home entertainment equipment connected to the ILD and the AC power to your home goes off (even momentarily) the ILDTm unit will automatically disconnect your equipment and revert to the protected mode. This protects your equipment from damaging surges due to power on/off cycles or lightning on the power line, in the event the disruption is due to an electrical storm.

Q. Are there any limitations on how many pieces of equipment one ILD unit can protect?

A. The ILD can provide a maximum of 10 AMPS of AC power to connected equipment, normally enough for a home entertainment system or a complete computer setup (cpu, monitor, printer, etc.,)--just add up the amps on the labels of the individual pieces of equipment. The ILD also provides for one coax and data line Input and Output.
