Description

The Nardalert XT family of RF personal monitors is de­signed to satisfy the needs of virtually all individuals who
use an RF personal monitor.

· Models are available that closely conform to all major
worldwide standards.

· The adjustable alarm feature allows one alarm to be
set at a level equal to the upper tier of two-tier stan­dards, such as “Occupational” or “Controlled” limits,
while the second alarm can be set to the lower tier,
such as the “Uncontrolled” or “General Population"
limits.

·

The ultra-broadband sensors cover almost the entire
usable RF spectrum in a single monitor.

·

The unique tri-sensor design handles every possible
signal format, from complex multi-signal communica
tion environments to military platforms with both com
munications and radar signals.

·

The five flashing high-intensity LED level indicators
can be seen while wearing the monitor, even out
doors in the sun.

·

There are four different ways to wear the monitor –
pocket clip, belt clip, soft case with belt clip (optional)
and soft case for climber’s harness (optional).

·

The audio alarm has two distinct sounds that are as
sociated with the two different alarm thresholds. Both
alarm thresholds can be adjusted using the optional
Interface Kit.

· The user can select an audio alarm, a vibrator alarm,
both audio and vibrator, or an optional remote vibra­tor. The remote vibrator can be used in areas with
high ambient noise when the user is wearing heavy
clothing that would prevent the detection of the inter­nal vibrator.

· The data logger is always on. The logging interval can
be adjusted using the optional Interface Kit.
At the default setting, the average field strength is
logged every five seconds with the data logger retain­ing more than 40 hours of information before it starts
to write over the oldest data.

·

Either one or both of the two LEDs that indicate the
lowest levels (10% of Standard and 20% of Standard)
can be deactivated using the optional Interface Kit for
applications where it is desirable to indicate only
higher field strengths.

Applications

-

Nardalert XTs are usable over their entire rated frequency
range when worn on the body as an RF personal monitor.
The patented sensor design detects the electric field over
an extremely broad frequency band regardless of signal
format or polarization.

·

The low frequency sensor is a low impedance, sur
face-area sensor designed to detect the radial fields
that are characteristic of low-frequency communica
tion systems. The compensated diode detector yields
accurate results even in highly complex, multisignal
environments.

50 Years of

Excellence

The diode-dipole design complements the low

·

frequency sensor in the UHF region by detecting
vertically polarized fields. The combination of the two
sensors detects all polarizations.

The microwave band sensor uses thermocouple

·

detectors. Thermocouple arrays function primarily
as dipole antennas up to about 10 GHz. At higher
frequencies, the sensor increasingly functions in the
traveling-wave mode of detection. This enhances the
sensor’s sensitivity and allows it to function accurately
up to 100 GHz and beyond. Thermocouple
detectors are always true RMS detectors and yield ac
curate results even with extremely narrow radar
pulses.

The 8861 Series is specifically designed for use in strong
ELF fields, such as where wireless antennas are mounted
on towers that carry high voltage 50/60 Hz utility power.
The 8860 and8862 Series NardalertXT models arenot de
signed for this environment and false alarms may occur.

The 8864 Series is specificallydesigned tobe wornon the
outside of RF protective suits since monitors do not func­tion properly when worn underneath these suits. RF pro­tective suits generally provide a minimum of 10 dB (10:1)
protection. The 8864 Series monitorssound an alarm at high
field levels to warn the wearer that they are in an area where
the RF protective suits may not be sufficient protection.

Personal and Area Monitors

The pocket clip supplied
with the monitor allows
you to wear the monitor in
side your shirt pocket
while maintaining the top
of the monitor near the top
of the pocket, regardless
of pocket size. This allows
you to view the LED
level-indicators.

-

The belt clip supplied with

-

the monitor snaps on the
monitor case in place of
the pocket clip. It has a
strong spring and retain
ing hook that makes an ac
cidental detachment from
your belt unlikely.

Model 8865 Interface Kit

The Model8865 Interface Kit, although not required, allows
Nardalert XT users to perform two important functions:

·

Adjust several monitor parameters, such as
alarm-threshold settings and data-logging rate

·

Download and analyze logged data

The Nardalert XT is ready to use upon receipt. If you want
to take advantageof these additional features all you need
is one Interface Kit per location. For example, if your New
York office has 30 Nardalert XTs, all you need is one Inter
face Kit. Of course, if you also have monitors in another
city, then you will probably want a kit for every city.

The Model 8865 Interface Kit is comprised of:

·

A small electronic module that connects the Nardalert
XT to any Windows

·

The Nardalert XT User’s Software (CD)

·

A cable to connect the module and the PC (RS-232)

·

A cable to connect the module and the monitor

·

A plastic storage box

The User’s Software is very easy to use. Although a com
plete manual is included on the CD and is available from
the help menu, fewusers ever needto referto the manual.
A “tool tip” appears for every control and window when
you pause the cursor near the control. Anyone familiar
with Windows programs has seen the words “Cut” or
“Paste” appear in other programs.
