FiveStar Alarm
Technical Manual
Chapter 1, Setup and Configuration
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 CH4 combustible 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:
FiveStar Alarm

Chapter 1, Setup and Configuration
Technical Manual
• 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.
1-2
FiveStar Alarm
Technical Manual
Chapter 1, Setup and Configuration
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.
2.
3.
4.
Verify that instrument is OFF; remove the battery pack.
Remove sensor cover screws and cover.
Gently lift out and properly dispose of sensor to be replaced.
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
Figure 1-1.
Board.

Chapter 1, Setup and Configuration
Technical Manual
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).
1-4

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

Special Instructions for Instruments
with Chlorine Dioxide Sensors
Calibration
FiveStar Alarms equipped with chlorine dioxide sensors may be
calibrated directly, using s third party-supplied chlorine dioxide
generator, or using cylinders of chlorine gas.
When calibrating with a chlorine dioxide generator you must
either ensure the flow supplied by the generator exceeds the
FiveStar pump draw (typically between 0.25 and 0.40 lpm) or you
can supply the gas directly through a calibration cap. Hooking the
pump directly to the generator may result in altering the
concentration supplied; therefore, a "Tee" must be used to bleed
Figure 2-12.
Setup for Chlorine Dioxide Generator Bypass
off the excess flow (FIGURE 2-12).
If a "Tee" is used, you must make sure the flow through the free
leg of the tubing is positive to be sure no air is being drawn in,
reducing your sample concentration. Once set up, follow the
instructions in the Technical manual (P/N 710440) for calibrating
the FiveStar Alarm and set the chlorine dioxide reading to the
known concentration from the generator.
When using a cylinder of chlorine gas, set the reading to one-half
the known concentration of the cylinder (e.g., for MSA P/N
710331, 2 ppm, set the reading to 1.00 ppm chlorine dioxide).
