Tsunami Multipoint Version 1.3 Installation Guide
Where Should the Protection Units be Located?
At least one unit should be installed near every outdoor Tsunami unit. General guidelines are:
▪ Locate protection unit as close to the outdoor Tsunami unit as possible, where the lightning protection
unit can be securely mounted to a flat surface and grounded properly. Ideally, this should be no
further than five feet away from the outdoor unit.
▪ Locate one unit at the roof penetration point, outside, so that the cable immediately enters the
building after the protection unit. This unit is optional if the distance from the first unit to the roof
penetration point is relatively short (under 15 feet).
Installing two units provides the maximum protection against lightning damage to the outdoor Tsunami
unit and the indoor power adapter, especially if the CAT5 cable length is greater than 15 meters.
