Power Sources.
Usually, the main power source at a post is a local
public utility.
The interest of the guard force begins at the points at
which feeder power lines enter the post. An alternate source of power should
be provided where the primary one is subject to interruptions or failures.
Standby gasoline-driven generators with automatic starters will ensure
continuous light. These generators begin to run upon the failure of outside
power. However, they may be inadequate for sustained operations of the post.
Generator or battery-powered portable and/or stationary lights should be
available at key control points.
They can be used in case of a complete
failure. This is one in which even the secondary power supply of the post is
rendered ineffective.
