Lightning

The control panel design significantly reduces the adverse effects of lightning. Taking
installation precautions can further reduce these adverse effects.
Effects of lighting
Electronics involved in a direct lightning strike or near a lightning strike can show adverse
effects. When lightning strikes, several things happen:
–
–
–
The effects of lightning can include trouble events, alarm events, and physical damage.
Installation precautions
To minimize the undesirable effects from lightning:
–
–
–
–
–
Warranty regarding lightning
The warranty does not cover physical damage due to lightning.

Power

Caution!
Remove all power (AC and battery) before making any connections. Failure to do so might
!
result in personal injury and/or equipment damage.
Caution!
Do not short-circuit the terminals of the transformer: Shorting the terminals opens the
!
internal fuse, causing permanent failure. Connect the transformer to the control panel's AC
power terminals before plugging it into the power source.
Notice!
Plan ahead
Route telephone, SDI2 bus wiring, and sensor loop wiring away from any AC conductors,
including the transformer wire. AC wiring can induce noise and low level voltage into adjacent
wiring.
Warning!
High current arcs are possible. The positive (red) battery lead and the terminal labeled BAT+
!
can create high current arcs if shorted to other terminals or the enclosure. Use caution when
working with the positive lead and the terminal labeled BAT+. Always disconnect the positive
(red) lead from the battery before removing it from the terminal labeled BAT+.

An electromagnetic wave spreads from the center point of the strike inducing high
voltages onto nearby conductors.
The voltage changes substantially on electrical grounds near the lightning strike.
High voltages are induced onto anything directly struck by lightning.
Do not run wiring outside the building.
If you install the unit in a metal building, keep the wiring at least 2 ft (0.61 m) away from
external metal surfaces. Make a proper earth ground connection.
Earth ground the unit correctly. Do not use an electrical ground or telephone ground.
Avoid running wires near telephone, data, or power lines. Locating control panel wiring at
least 2 ft (0.61 m) away helps reduce the effects of lightning.
When your data lines must cross the path of AC or other wiring, cross perpendicular to
the lines.
