Non-Contact Voltage Test (VoltAlert™)
VoltAlert is a non-contact voltage (NCV) test of the
incoming voltage to the ballast of a fluorescent light fixture.
The fluorescent light fixture must be turned on for this test.
The blinking red LED is a self-test feature for visual
confirmation of battery and power on. It provides a double
flash every 2 seconds.

Warning
To prevent possible electrical shock, fire, or
personal injury:
•
Do not use VoltAlert if the LED test indicator
does not blink when you enable the function.
•
Test VoltAlert on a known voltage source
before and after use to make sure the
Product functions properly.
•
Completely collapse the rod extender
during the VoltAlert test.
•
Do not allow the rod extender to contact
live voltage.
•
When using VoltAlert, if the test indicator
does not glow or the beeper does not sound,
hazardous voltage could still be present.
VoltAlert indicates active voltage in the
presence of electric fields of sufficient
strength generated by the source (MAINS)
voltage. If the field strength is low, the
Product may not provide indication of
hazardous voltages. Lack of an indication
may occur if the Product is unable to sense
the presence of voltage which may be
influenced by several factors including, but
not limited to:
-
Shielded wire/cables
-
Adjacent grounded conductors
-
Thickness and type of insulation
-
Distance from the voltage source
-
Fully-isolated users that prevent an
effective ground
-
Receptacles in recessed sockets
and/or differences in socket design
-
