Chapter 1
Set-up and Configuration
The user must be familiar with the procedures in the FiveStar
Alarm Instruction Manual, including all cautions and warnings.
The FiveStar Alarm can be configured in many ways to meet
your changing gas detection needs. There are four means for
making instrument configuration changes (the first two are
described in the instruction manual, the third is described in this
chapter, and the fourth is accessible only with FiveStar LINK):
1. At instrument turn-ON,
the following setup option is available:
•Fresh Air Setup (if enabled).
2. When attaching the battery to the instrument,
the following setup options are available:
•Language for displays (if enabled)
•Operating Beep
•Peak / STEL / TWA displays (all/none)
•Set time and date
•Sensor configuration.
3. During Sensor setup or sensor autoconfiguration,
the following setup options are available:
•LEL versus CH4combustible display
•Gas sensors installed
•Reset alarm settings to factory defaults.
4. FiveStar Link is a separately-supplied software package for
communicating to the FiveStar instrument with a personal
computer. To operate, FiveStar Link requires a set of
software and an Infrared adapter. These components may
be purchased together (as P/N 710988) or separately.
With FiveStar Link software, the following options can be reset:
Technical Manual Chapter 1, Setup and Configuration
FiveStar Alarm 1-1

•Eight-character instrument "name" shown on
instrument startup (default is "PASSPORT")
•Change alarm setpoints
•Set backlight time-out (1 minute to 20 minutes)
•Operating beep
•Individually turn ON/OFF Peak, STEL
and/or TWA pages
•Disable Fresh Air Setup (available only in
instruments with software V1.2 or higher)
•Set Time and Date (available only in instruments
with software V1.2 or higher)
•Disable Autoconfigure (available only in instruments
with software V1.2 or higher)
•Enable or disable Data Tagging
(software V2.0 or higher)
•Enable or disable the "display alarms" on start-up
option (software V2.01 or higher)
•Enable or disable the multilingual function
(English/Spanish/Canadian French
software V2.01 or higher)
•Disable Autocalibration capability
(software V3.0 or higher)
•Change Periodic Datalog intervals
(software V3.0 or higher).
Sensor Autoconfiguration
and Replacement
When a sensor is replaced, when a new type of sensor is
installed or when a sensor is removed, the FiveStar Alarm steps
the user through an "autoconfiguration" program. All instruments
leave the factory with the autoconfigure feature enabled. The
FiveStar Link program may be used to disable this feature if the
user desires.
Chapter 1, Setup and Configuration Technical Manual
1-2 FiveStar Alarm

The autoconfiguration feature allows the user to change the
instrument sensor configuration as the user’s gas sensing needs
change. The unit steps through the autoconfiguration sequence
(listed later in this chapter) when the instrument recognizes that:
•a new serial number sensor is installed (a replacement)
•a sensor is removed
•a new type of gas sensor is added.
"CAUTION
When removing or installing the combustible gas sensor,
remove the battery pack. Otherwise, the sensor pins may
short to the case and cause an "ERROR 5" message (damage
to the combustible sensor circuit).
Replacing a Sensor
To replace a sensor in your FiveStar Alarm:
1. Verify that instrument is OFF; remove the battery pack.
2. Remove sensor cover screws and cover.
3. Gently lift out and properly dispose of sensor to be replaced.
4. Inspect the condition of electrical contact "Zebra Strip" located
below the sensor.
•The "Zebra Strip" is a small, black conductive elastomer
which makes contact to the sensor memory chip on the
bottom of the sensors (see Chapter 4, FIGURE 4-1).
•If this is not in place or is not making good contact,
the instrument will not properly recognize the
installed sensors.
5. If the Zebra Strip is damaged or missing,
replace it with a new Zebra Strip (P/N
655188) before installing new sensor.
6. If replacement sensor is equipped with a
shorting plate, clip or wire attached to
its pins, remove plate, clip or wire
before inserting the replacement
sensor.
7. Carefully align the new sensor contact
pins with the sockets on the Sensor
Board. Figure 1-1.
Sensor Replacement
Technical Manual Chapter 1, Setup and Configuration
FiveStar Alarm 1-3

8. Press the new sensor into place.
9. Replace the sensor gasket and sensor cover.
10. Re-install screws to hold down the sensor cover.
"CAUTION
Do not operate the instrument without the sensor cover
fully installed. The zebra strips require pressure to enable
proper contact. Without proper contact, data may be written
improperly to the sensor memory and the data may become
corrupted, rendering the sensor unusable.
NOTE: NO, Cl2, ClO2, and NH3 sensors are "biased"
sensors. As such, they require approximately 12
hours once installed (with battery pack attached, but
turned OFF) for the output to stabilize. Allow the unit
to stabilize before calibrating and using in the field.
11. Replace cover before turning instrument back ON to
verify configuration.
•The sensor cover holds the sensors down firmly against
the Zebra Strips to ensure proper electrical contact.
12. Turn the instrument ON and proceed through sensor setup.
•The instrument proceeds to a sensor update mode similar
to that for adding or deleting a sensor. See "Sensor
Autoconfiguration" later in this chapter for instructions.
•If instrument autoconfiguration is disabled, the instrument
shows an error message. See "Manual Sensor
Configuration" later in this chapter for instructions on
manual configuration.
"WARNING
Verification of calibration response is required; otherwise the
instrument will not perform as required and persons who rely
on this product for their safety could sustain serious personal
injury or death.
Installing a New Type of Sensor
1. Verify that unit is OFF.
2. Remove battery.
3. Remove sensor cover screws and sensor cover (FIGURE 1-2).
Chapter 1, Setup and Configuration Technical Manual
1-4 FiveStar Alarm

4. Verify that the electrical
contact Zebra Strip
below sensor is not
missing or damaged.
•The Zebra Strip is a
small, black
conductive elastomer
which makes contact
to the sensor memory
chip on the bottom of
the sensors
(FIGURE 4-1).
•If Zebra Strip is not in
place or making good
contact, the unit will
not properly
recognize the installed
sensors.
•If the Zebra Strip is
damaged or missing,
replace it with a new
Zebra Strip
(P/N 655188) before
installing the sensor.

•Pressing PAGE (SKIP) exits the autoconfigure sequence.
•The instrument displays the FIGURE 1-13 screen to remind the
user to:
•check the sensor cover to ensure that "missing sensor"
labels (P/N 710478) cover slots where sensors are
not installed
•verify there are no "sensor missing" labels over any
position where a sensor is installed.
"CAUTION
Failure to install the "Missing Sensor" label exposes the sensor
cavity to dirt and water and may lead to instrument damage.
This can also increase instrument response and clear times
when operated in pumped modes.
•Pressing the PAGE (QUIT) button powers down the instrument.
•Pressing the RESET (OK) button sends the unit into the
calibration mode.
•See Chapter 2 for "Calibration Procedure."
NOTE: Once the instrument has performed the
autoconfiguration procedure, any newly installed
sensor must be calibrated prior to use.
NOTE: For instruments with software versions lower than 1.2,
all calibration data will be reset to the default values
in the sensor memories; the entire instrument must
be recalibrated.
It is recommended that all sensor calibrations be checked
after autoconfiguration is run and prior to instrument
use.

Calibration
Optional Fresh Air Setup
The FiveStar Alarm can be set to allow the user to automatically
zero the measurement systems and calibrate the oxygen system
when the unit is turned ON.
Activating the Fresh Air Setup Option
Configuration of the Fresh Air Setup is done by way of the MSA
LINK program. See instructions in the MSA LINK program
software for this information.
When this feature is activated and the instrument is turned ON,
the FiveStar Alarm completes its self-tests and asks if a Fresh
Air Setup is desired (FIGURE 2-1).
To Cancel Fresh Air Setup
•If the PAGE (NO) button is pressed or if no button is pressed
within five seconds, the instrument does not perform a Fresh Air
Setup. Instead, it goes on to operate in the normal measure
mode and displays the Exposure page.

To Perform Fresh Air Setup
Press the RESET (YES) button within five seconds.
•The FiveStar Alarm begins to perform a Fresh Air Setup.
•Oxygen is set at 20.8 percent.
•All other gases are set at zero.
NOTE: If the Fresh Air Setup feature is activated and an error
message is displayed, press the RESET button to
exit the Fresh Air Setup and enter the Measure
mode. This may occur if the original readings were
outside of the limits for the Fresh Air Setup feature.
This is to protect the user from zeroing out
potentially hazardous gases.
Persons responsible for the use of the FiveStar Alarm must
determine whether or not the Fresh Air Setup option should be
used. The user’s abilities, training, and normal work practices
must be considered when making this decision.
Calibration Adjustment
FiveStar Alarm calibration can be adjusted easily by using gases
of known mixtures and concentrations.
Preparing to Calibrate
Before starting, be certain that the instrument is in normal fresh
air, free of combustible or toxic gases. If the ambient air has
contaminants, use bottled zero air (20.8% oxygen in nitrogen)
when applying fresh air. To prepare to calibrate:
1. Turn OFF the FiveStar Alarm.
2. Allow the instrument to stabilize for several minutes in fresh
air at the temperature and air pressure of intended use.
"WARNING
The FiveStar Alarm does not provide any protection while
the calibration is being adjusted. Do not rely on the
instrument for protection at this time; otherwise, serious
personal injury or death could result.
