Testable using LSR-Tester

The LSR2 can be installed at any location on the down-conductor route between the air terminal and the earthing

system. Where possible, avoid installing the LSR2 in a position where it is exposed to direct sunlight. This can be

achieved by installing the LSR2 in a suitable mounting cabinet.

The LSR2 should be mounted in line with the down-conductor as shown in Figure 1. If using flat down-conductor

use the plastic spacer provided, as per Figure 2. To remove or relocate the LSR, use a small flat bladed screwdriver

to release the clip on the latching mechanism on the cable tie.

Lightning Strike Recorder LSR2

LPI

Lightning Strike Recorder (LSR2) is a lightning event counter. The LSR2

is simply mounted at any location along the down-conductor route. Its purpose

is to record the number of lightning strikes captured by the lightning air

terminal and conveyed by the down-conductor.

The LSR2 operates by sensing current by means of an inductive pick up loop.

The loop passes along the inside surface of the bottom of the enclosure. This

loop detects lightning current impulses on the down-conductor and sends a

trigger to the counter, which turns the counter over to register the event. The

Recorder is mounted in a polycarbonate enclosure rated IP 65.
