Lightning & Surge Protection



Lightning and Surge Protection



MAXIMUM LIGHTNING PROTECTION™ for 66 BLOCKS

Maximum Lightning Protection on a 66 Block with Ground Bus, with a Test ShoeThe Phone Company always provides basic Lightning Protection at the entrance to a building.

Basic protection prevents an old style non-electronic telephone along with the wiring in the building from burning up. This basic protection lets so much voltage and current through that anything electronic will likely get blown up.

Click to see bigger picture of a Maximum Lightning Protector Module

Our Maximum Lightning Protection™ modules are engineered to protect specific types of telephone and data equipment attached to phone lines, based on the type of phone line, and the equipment attached.

Maximum Lightning Protection™ modules are Solid State, automatically clamp large surges down to 10-15 volts, and have self-resetting Over Current Protection to handle up to twice the damaging current of any other Lightning Protector.


We call it Maximum Lightning Protection™ because this is the best lightning protection money can buy...

Unless you use an expensive device that converts to fiber and back (lightning will never get past fiber!)


While the Phone Company has a single type of protector they install on every line (called primary protection... see an explanation below*), if you have electronic phone equipment you also need the Secondary Protection offered by our Maximum Lightning Protection™ modules.

The biggest risk of lightning damage? An OPX (Off Premise Extension), where an electronic or analog station port leaves a building... even for 5 feet!

If you have OPXs leaving a building going to another building,
you ABSOLUTELY need the correct Maximum Lightning Protection™
module for the type of equipment on the line.

It doesn't matter whether the cable goes 10 feet or 10 miles, whether it's in conduit or just buried in the ground 2 inches or 2 yards deep, lightning will find that cable and damage your expensive electronic equipment. Conduit will not prevent lightning from getting to a cable running outside a building.

Maximum Lightning Protection™ Features:

Always use an AC Outlet Tester to see if an outlet is wired correctly!

Lightning Protectors won't do anything without a
GOOD GROUND!

When used with our Maximum Lightning Protection™ Modules, the ground diverts high voltage from lightning or a surge to the earth, instead of letting it get to the electronic equipment.

In the old days, a cold water pipe was considered the best ground available. Today, you should never use a cold water pipe for a ground since there is so much PVC (non-conductive) pipe out there.

The Phone Company ground at the NI (Network Interface) is not considered a good ground. It may not even be attached to anything!

The best ground to use today is the electrical panel, which should be grounded to a ground rod driven into the earth just outside the wall where the panel is located. Be sure to check that there is a ground on the outlets with an AC Outlet Tester (above right).

NOTE: An AC Outlet Tester will tell you if the outlet is wired correctly and if a ground is present, but not the quality of the ground. You should look to make sure the AC power panel is physically wired to the ground rod. If you're not sure, special testers are available that will verify the quality of a ground.
 

IMPORTANT!   In rocky and sandy areas (like on a mountain or beach) you'll need a professional to come out and install the best ground possible. A regular ground rod won't give you a good ground in rock, gravel, clay or sand. This applies to both voice and data lightning protectors and AC powered devices with AC surge protectors.

Our Ground Plug with 10' Ground Wire will save you a ton of time running a separate ground to the power panel. Just plug it into an AC outlet, run the wire over to the 66 Block, and attach the wire to the Ground Lug that's included with the Ground Bus.

Never let a pair into or out of a building without
Maximum Lightning Protection™!

Phone systems have no protection built-in for stations, so almost any surge will knock out an expensive analog or digital station card. Phone system manufacturers know that the CO lines are coming from outside the building, so they build basic lightning protection into the trunk cards. They figure only a very small percentage of stations will leave a building, so they build no protection into stations (since all of their customers would have to pay for the very small percentage of customers using OPXs).

Don't even think about running a station outside of a building, even for 5 feet, without the correct Maximum Lightning Protector™.

How do you know if a Lightning Protector has worked?

Lightning or Surge Protection (AC or telephone) has worked if the equipment isn't blown up after a storm!

If the equipment is damaged, the Protector(s) should be tested to see if a component is damaged.

If the equipment is damaged, and the Protector isn't damaged, that means there was a bad ground (or no ground) attached to the Protector. A Protector should fail shorted to ground before allowing damaging voltage or current to get to the equipment it's protecting.

Unlike a Protector with a "Sneak Fuse," our Maximum Lightning Protectors™ have a solid-state self resetting electronic fuse that prevents service calls in all but the worst lightning storms (where the whole Protector will be blown-up, saving the telephone equipment).

So what's the difference between Primary and Secondary Lightning Protection?

Primary Protection is normally a carbon or gas tube protector with a good ground (usually installed by the phone company) that diverts high voltages of over 500V or so to ground, in 100ns or more. Secondary Protection will divert the high voltage surge to ground at a much lower voltage, much faster, and will also usually add over current protection.

NOTE: Nothing will stop a direct hit from lightning. A direct hit (or even a hit in the general area) is so powerful that it can blow up battery operated devices like smoke detectors. Regular business insurance generally doesn't cover telephone systems that are damaged by surges, flood or water leaks. It's not a bad idea to check out EDP (Electronic Data Policy) insurance, which will cover you for this type of damage to your computers as well as telephone equipment (subject to a deductible).

So far every direct hit has resulted in the Maximum Lightning Protector™ turning into a glob of bad smelling plastic. It gave its life to protect the equipment, but it failed shorted to ground (so the equipment can't be damaged by further lightning hits) and will need to be replaced.



MLP-270 1 CO LINE PROTECTOR

Click to see bigger picture of Maximum Lightning Protector Module

You need one Protector for each regular phone line or analog station port (pair) with ring voltage.

If the line doesn't have ring voltage, use one of our lower voltage Protectors (below).

If you're putting this on an analog station port going to another building (OPX), be sure to put them at BOTH ENDS of the cable leaving the building!

MLP-070 1 PAIR DIGITAL EXTENSION PROTECTOR

You need one Protector for each line (pair) with a maximum DC voltage of 70V.

Be sure to put them at BOTH ENDS of the cable leaving the building!

NOTE:   We received a report that the MLP-050A didn't work on a digital station port on a Samsung system, which the customer measured at 55VDC. The MLP shorts the line to ground if the voltage on the pair is higher than the voltage the MLP is rated at, which is what it's supposed to do.

The MLP-070 will work on a digital station port up to 70VDC.

Be sure to put them at BOTH ENDS of the cable leaving the building!

MLP-050A 1 PAIR DIGITAL EXTENSION PROTECTOR

You need one Protector for each line (pair) with a maximum DC voltage of 56V. For higher voltages on digital extensions, use the MLP-070 with a maximum DC voltage of 70V (below).

Be sure to put them at BOTH ENDS of the cable leaving the building!

This is the most common Protector used for a digital or electronic station port, or ISDN (with or without DC sealing current).

NOTE: Some electronic phone systems use two pairs for the electronic stations, but the first pair is actually also an analog station port with ring voltage (examples would be most Panasonic systems and the AT&T/Avaya Partner). In that case, you would use an MLP-270 Protector on the first pair, and an MLP-050A Protector on the second pair that you send outside the building.

66 BLOCK TEST SHOE

66 Block Test ShoeClick to see bigger picture of Maximum Lightning Protection on a 66 Block with Ground Bus, with a Test Shoe

If you need to test one line in the middle of a bunch of lines, it can be hard to get your Butt-set clips on the 66 block.

The 66 Block Test Shoe lets you test a line by removing a 66 Regulator, 66 Lightning Protector, or 66 Line In-Use Indicator, and placing the Test Shoe in its place. Attach your Butt-set to the clips on the front, and push the red switch to open the line and disconnect the equipment during testing.

Remember that the phone line always comes in on the left on an RJ-21X block, and the CPE equipment is always on the right.

3 PRONG AC OUTLET TESTER

Always use an AC Outlet Tester to see if an outlet is wired correctly!





Use it for every piece of equipment that plugs into AC!

Just plug it into an AC outlet! It tells you whether the outlet is wired correctly, and if there's a ground on the third prong. Without a ground, electronic equipment may not operate properly, which is also the case if hot and neutral are reversed.

If something strange is happening this is the first thing you should check!

NOTE: An AC Outlet Tester will tell you if the outlet is wired correctly and if a ground is present, but not the quality of the ground.

Style may vary.

1080 JOULES AC SURGE SUPPRESSOR

1080 Joules AC Surge Suppressor

Great Inexpensive AC Surge Protector!

Has three AC outlets on the front

EMI / RFI Filtering

125 Volt, 15 Amp, 1800 Watt, Full 3 Line AC Surge Protector


This is really a great surge protector!   When our engineer was investigating AC surge protector manufacturers he looked at this one, checked the specs, checked the components used, and decided it will give you great surge protection for phone systems and most modern electronic equipment.... At a great price!

There is a difference between this surge protector and others!  Some surge protectors continue to provide power to the outlets after they've been damaged by a surge (they will all go bad eventually). A light may go off on some, which nobody will ever notice, or on high end surge protectors a beeper will go off indicating there is no longer any surge protection.

On this Surge Protector, the power will shut off when the
internal protection is damaged by an electrical surge.

That means the phone system, computer or whatever is plugged into it will go dead, because the power to it has been shut off by the Surge Protector. Is that a good idea? I think so, but you should consider the application before using this type of AC Surge Protector.

Even if you are using a Battery Backup with surge protection, most of them will still provide power after the internal surge protection is damaged. They'll usually light a cryptic light on the front panel that gives you no clue of why it's on.

If your phone system or computer goes dead after the Surge Protector is damaged, at least you'll have a chance to replace the surge protector... which isn't always your option with surge protectors that just light a light when they're damaged.

IMPORTANT NOTE: Like our phone line protectors, this AC Surge Protector won't survive a direct lightning strike, which is so strong that it will often damage a battery operated device (like a battery operated smoke detector!). That's a good reason to make sure you have electronic equipment insurance coverage on your business insurance policy (believe it or not, it's not automatically included unless you ask for it).
