Principles of Operation SIGALARM's
Power Line Proximity Alarm performs in two different
modes:
1. As an automatic early warning system.
Anytime the system is turned on, whether activated
at engine start up (wired through the ignition) or
by the power switch on the front of the control
panel, it will automatically be set at its most
sensitive setting. At this setting, the system can
sense as little as 110 volts AC, warning the
operator (and crew) that he is in the vicinity of a
high-voltage power line. The operator need not set
or adjust the system for it to operate in this early
warning mode --- it occurs automatically!
2. As a
Proximity Alarm Once the operator has been alerted
to the presence of an energized power line in the
vicinity of his work area, he may choose to stay far
away. If the job assignment calls for working in
close proximity to the power line --- please, no
closer than 20 feet --- the system can be set to
alarm any time the boom comes within the preset
distance. The entire length of the SIGALARM sensor
antenna continuously receives (detects) the signal
(electrostatic field) produced by all energized
power lines. This signal is amplified by the
electronics on the main control unit. "Course" and
"Fine" controls allow the operator to set the alarm
circuits to "go off" at a predetermined distance
from the power lines, producing both visual and
audio warnings. The repetition rate of both the
visual and audible alarms increases as the boom or
extension moves closer to the "hot" power line.
SIGALARM continues to warn until the boom is
withdrawn from the danger zone.
