D9412GV2/D7412GV2 Operation and Installation Guide 2.0 Lightning Strikes

2.0 Lightning Strikes

The control panels are designed to significantly reduce electromagnetic interference and malfunction generally caused by lightning.

2.1Effects

Any electronic system can be struck directly by lightning or be adversely affected by a lightning strike near the system. When lightning strikes, several things happen:

•An electromagnetic wave spreads from the point of the strike inducing high voltages in nearby conductors.

•The voltage changes substantially on electrical grounds near the lightning strike.

•High voltages are induced upon anything directly struck by lightning.

Symptoms of installations that lightning might strike or affect are Missing Trouble, Missing Alarm, or Point Bus Trouble events. Occasionally, Reboot and Watchdog events might be sent because the control panel tried to reset itself.

Electronic systems, including control panels, cannot be completely immune to direct or indirect lightning strikes; however, some proven installation practices might greatly reduce the risk of undesirable affects.

2.2Precautions during Installation

To minimize the risk of undesirable effects from lightning strikes on high risk installations that use a point-bus technology:

•Do not run wiring outside the building.

•If you must install the unit in a metal building, keep the wiring at least 0.61 m (2 ft) away from external metal surfaces.

•Earth ground the unit correctly. Do not use an electrical ground or telephone ground.

•Avoid running wires near telephone, data, or power lines inside a building. Historical evidence shows that locating control panel wiring at least 0.61 m (2 ft) away from telephone, data, or power lines is successful at minimizing lightning damage. When your data lines must cross the path of AC or other wiring, cross the lines perpendicularly.
