For your safety:
Failure to follow operating instructions could result in death or serious injury. Please read and
follow all instructions and guidelines before using products.
United Safety Incorporated and its distributors cannot be held responsible for improper or
neglected maintenance, improper installation, or behavior that violates State, Federal an
international laws and guidelines.
THIS IS AN ASSISTIVE AND INTERACTIVE DEVICE-it cannot guarantee operator safety
Do not use product or machinery within 20’ from overhead power lines.
Do not operate any part of equipment directly above or below overhead power lines.
Contact with high voltage will result in serious injury or death. Observe general safety
precautions when near high voltage power lines.
If product is damaged or collides with obstructions, remove unit immediately and return to the
manufacturer for repair or replacement. Operating a damaged unit could lead to system failure.
This device is used to detect 50 and 60 Hz OVERHEAD power lines greater than 5000V volts
By using United Safety Incorporated products you understand and agree the dangers of
operating machinery or equipment near overhead power lines and are familiar with associated
risks.
In no event shall United Safety Incorporated or its distributors be liable for any direct, indirect,
punitive, incidental, special consequential damages, to property or life, whatsoever arising out of
or connected with the use or misuse of our products.
The Voltek NS does not measure or indicate distance. Power line proximity alarms measure
relative strength of electromagnetic elds surrounding overhead power lines. Proximity alarms
are interactive devices provided to assist you the operator in avoiding contact with power lines.
It is the expressed goal of United Safety Incorporated to provide you with the best safety
products available, however it is imperative that the operator takes time to become fully
educated in the potential hazards his or her work environment. We work to provide you with an
extra measure of safety, however it is ultimately up to you to maintain a hazard-free job-site.
Have a safe and productive day and let us know if we can do anything further to help you with
your power line safety needs.
Sincerely,
United Safety Incorporated staff

• Detects 60Hz (domestic) and 50Hz (foreign) overhead
Voltek Ns features:
SPOTTER features:
power lines greater than 5 kV AC
• Dust and waterproof enclosure (IP 67 rated)
• Operates on 12-24 V DC
• Back-lit LED display
• Adjustable sensitivity level
• 120db external siren
• Sensitivity recall function
• E-stop/hydraulic integration can shutdown equipment
or hydraulics when you are too close to power lines
• Antenna self test
The Spotter allows you to operate the Voltek NS remotely.
It features the same controls and user interface as the NS
with the addition of a warning button to sound the siren in
an emergency and a shutdown button to stop or shutdown
your equipment (if integrated).
• 500’+ transmission range
• 40+ hours continuous run time between charges
• Back-lit display
• IP67 water, dust, and shock resistant
• “Warning” button allows operator to sound the siren for
emergency situations
• “Shutdown” button allows operator to shut down
equipment in emergency situations
• Quickly and wirelessly links with any Voltek NS
how it works:
• Power lines are surrounded by an electric eld (E-eld).
• The strength of the E-eld surrounding the power line is dependent on several variables such
as but not limited to: voltage, the presence of multiple lines, and distance
• The NS uses a wire antenna running the length of the boom or mast of the equipment on
which it is installed to detect E-eld along it’s entire length.
• The NS detects the relative strength of the E-eld, translating it into audible and visual cues
to help you stay away from power lines.
• Adjustable sensitivity allows the NS to compensate for higher or lower voltage power lines or
overall distance from a power line
• The NS can be connected to the E-stop or hydraulic “dead-man” circuit on your pump
