Warnings and Cautions
A. Signal Words
The following signal words, as defined by ANSI Z535.4-1998, are used in the ToxiPro-
NGSG Operator’s Guide.

will result in death or serious injury.
indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.

affected area, and to return only after further testing determines that the area is
once again safe for entry. Failure to immediately leave the area may result in
serious injury or death.

tolerance must be replaced immediately. An instrument equipped with a toxic gas
sensor that fails calibration may not be used until testing with known concentration

again fit for use. Instruments equipped with an oxygen sensor that fail calibration
may not be used until testing with fresh air determines that accuracy has been

1. Overview
The ToxiPro is a single sensor gas detector
that can be configured to detect either oxygen
) or one of a variety of toxic gases. The
(O

ToxiPro’s sensor type is shown on the front of
the instrument and is also shown on the
display during the start up sequence. The
ToxiPro includes numerous features designed
to meet specific user requirements.
1.1 Methods of sampling
The ToxiPro may be used in diffusion mode,
or with the manual sample draw kit that is
available separately. In either mode, the
atmosphere must reach the sensor for the
instrument to register a reading. In diffusion
mode, the atmosphere reaches the sensor by
diffusing through the sensor port on the front
of the instrument. Normal air movements are
enough to carry the sample to the sensor.
During remote sampling, the gas sample is
drawn into the sensor compartment through
the probe assembly and a length of tubing.
See section 2.9 for more details on
sampling the atmosphere.
1.2 Sensors
All versions of the ToxiPro except the O
model use an electrochemical toxic gas
sensor. The ToxiPro O
uses a galvanic
2
oxygen sensor. Both types of sensor have
been designed to minimize the effects of
common interfering gases. These sensors
provide accurate, dependable readings for
gases commonly encountered in industrial
applications.
A sensor cross sensitivity chart is provided in
Appendix A at the back of this manual.
1.2.1 ToxiPro sensor ranges
Specific toxic sensor ranges and resolutions
are provided in the sensor replacement chart
in Appendix B.
1.2.2 ToxiPro O

warning state the LED’s will flash, yellow. In
the danger state the LED’s will flash, red.
Two oxygen alarm set points have been
provided for ToxiPro O
instruments. The
2
danger alarm is sounded for oxygen
deficiency and the warning alarm is sounded
for oxygen enrichment.
ToxiPro instruments equipped with a toxic gas
sensor have up to four alarm set points:
Warning, Danger, Custom, TWA (Time
Weighted Average) (if enabled) and STEL
(Short Term Exposure Limit) (if enabled).
The custom alarm level can be set to a level
greater than/equal to the danger alarm level
for toxic sensors and less than/equal to
danger level for oxygen sensors using the IQ
System software. The custom alarm is a
latching alarm. The custom alarm looks and
sounds similar to the DANGER alarm but,
with the warning symbol turned on and the
DANGER icon not being set. If the custom
alarm level has been reached then the alarm
can only be silenced by putting the instrument
in the dock (successful IrDA connection) or
successful connection to BioTrak. If the
custom alarm value is zero then the custom
alarm is disabled and “OFF” will appear on
the instrument’s LCD during the startup
sequence. If the danger alarm has been
disabled then the custom alarm is also
disabled.
Note: In the standard ToxiPro
configuration with toxic gas sensors, the
STEL and TWA alarms are not enabled.
The STEL and TWA alarms may be
enabled at the factory or through BioTrak
software. Call Honeywell Analytics for
more details.
1.3.2 Calibration and bump test due
notices
The ToxiPro includes bump test and
calibration due notices.
For more information on the calibration
due notices, see section 2.4 below.
1.3.3 Battery replacement Warning
If a new battery has been installed or the
existing battery was removed and replaced
the ToxiPro will show “F 0” on the display and
will beep 6 times upon startup. It will then go
into the set time/date mode.
1.3.1 Gas alarms
ToxiPro gas alarms are user-adjustable and
may be set anywhere within the range of the
specific sensor. When an alarm set point is
exceeded a loud audible alarm sounds. In the

1.3.4 Low battery alarms
The ToxiPro is designed with two battery
warning alarms that are activated when the
battery voltage is reduced to specific levels.
For more details on the battery alarm, see
section 2.5 below.
1.3.5 Missing sensor during startup
If the ToxiPro fails to detect
a sensor during startup, it will show “F 1” with
the caution symbol and then shut itself off.
For more details, see section 2.1.
1.3.6 Corrupt memory
The ToxiPro
continuously monitors its
onboard memory. If the
instrument determines
that the memory is
corrupt, it will display “F 4” and proceed to
shut itself off.
If “F 4” is displayed, contact Honeywell
Analytics for further details.
1.3.7 Vibrating Alarm Error
If the vibrating alarm fails “F 6” will be shown
on the display. Contact Honeywell Analytics
for further details.
1.3.8 Heartbeat Feature
A blinking heart is an active indicator,
notifying the user that the instrument is
operating normally.
1.4 Functions
1.4.1 Security beep
The ToxiPro includes a security beep that can
be enabled or disabled with BioTrak software
through the PC’s IrDA port. If the security
beep is enabled, the ToxiPro will emit a short
beep coupled with an LED flash at a specific
interval to remind the user that the instrument
is active.
1.4.2 Latching alarms
The ToxiPro includes latching alarms that can
be enabled or disabled with BioTrak software
through the PC’s IrDA port. With the alarm
latch enabled, the audible and visible alarms
will continue to sound even after the
atmospheric hazard has cleared. To turn the
alarm off once the hazard is no longer
present, simply press the MODE button.
1.4.3 Enhanced Latching Alarm
Note: V9.20 or greater ToxiPro firmware and
V8.00 or greater is required of all IQ System
software to support the Enhanced Latching
Alarm.
The enhanced latching capability can be
enabled for the danger alarm using an IQ
System template and apply the template in
ToxiPro IQ Express.
The user can specify the duration for latching
of the Danger alarm. When the instrument
goes into the danger alarm for greater than or
equal to the user defined duration for latching
then the alarm is latched.
When the alarm is latched and if the gas level
goes below the alarm level, the audible and
visual alarms will continued.
If alarm latching is enabled and the
instrument is in alarm for less than the
latching duration, the alarm will not latch
when the gas level drops below the alarm
level.
Latch Acknowledgement
A latched alarm latch can be acknowledged
by two methods. The first is either by mode
press or inserting the instrument into the
dock. The second is by dock insertion only.
The method is selectable in the IQ System
template.
Note: For more information on creating
and assigning templates, please refer to
the Database Manager Reference manual.
1.4.4 Silence warning alarms
The ToxiPro’s audible and vibrating (if so
equipped) alarms can be turned off during an
alarm condition by pressing the MODE button
if this function has been enabled with BioTrak
software. The visual warning alarm light and
readings will continue to indicate the alarm.
1.5 IQ Dock Compatibility
The ToxiPro must be equipped with
instrument firmware version 4.30 or higher to
be compatible with the IQ Express Docking
Station. The IQ Express Dock is an
automatic calibration station coupled with a
data management system. The IQ Express
Dock must be equipped with firmware version
6.53 or higher. Instrument firmware in the
ToxiPro may be upgraded at any time. See
section 5.2 below for details on software
upgrades.
