IMPORTANT! BUMP TEST THE MONITOR BEFORE EACH DAY’S USE
Prior to each day’s use, every gas detection monitor should be bump tested to confirm the response of
all sensors and activation of all alarms by exposing the monitor to a concentration of target gas that
exceeds the low alarm set point. A bump test is also recommended if the monitor has been subjected to
physical impact, liquid immersion, an Over Limit alarm event, or custody changes, or anytime the
monitor’s performance is in doubt.
To ensure greatest accuracy and safety, only bump test and calibrate in a fresh air environment.
The monitor should be calibrated every time it does not pass a bump test, but no less frequently than
every six months, depending on use and exposure to gas and contamination, and its operational mode.
• Calibration intervals and bump test procedures may vary due to national legislation.
• Honeywell recommends using calibration gas cylinders containing the gas that is appropriate to the
sensor you are using, and in the correct concentration.
Sensor Specifications, Cross-Sensitivities, And Calibration Information
For information on sensor specifications, cross-sensitivities, and calibration information, refer to RAE
Systems Technical Note TN-114: Sensor Specifications And Cross-Sensitivities (available for free
download from www.raesystems.com). All specifications presented in this Technical Note reflect the
performance of standalone sensors. Actual sensor characteristics may differ when the sensor is
installed in different instruments. As sensor performance may change over time, specifications provided
are for brand-new sensors.
Make Sure Firmware Is Up To Date
For best operation, make sure your monitor is running the latest firmware. Check
www.raesystems.com for updates.

5. Operation
Make sure the battery is installed before operating the MeshGuard LEL IR or MeshGuard CO2 IR.
Refer to page Error! Bookmark not defined. for information on battery installation and
replacement.
Note: The MeshGuard CO2 IR should be operated with a RAE PowerPak external battery.
5.1. Turning The Instrument On
Hold down the [MODE] key and release it when the instrument beeps. The monitor is now on, as
indicated by the display:
The display briefly shows the firmware version (for example, “F1.0” means firmware version 1.0,
“F2.0” means firmware version 2.0, etc.):
Then the display shows “SOn” as the sensor comes on.
It begins a sensor warm-up and counts down by seconds from 60 to 1.
The instrument initiates network communication and shows these displays in alternation:
Note: If the insrument is unable to find a radio network to connect with, it searches, and the display
alternates between “rdo” and “Srh” (for “radio search”).

MeshGuard LEL IR & CO2 IR User’s Guide
16
Next, if a network is located, an antenna icon appears (if no network is found, then the icon is not
shown; press [Y/+] to search for a network). The current gas concentration reading is also
displayed:
The instrument is now operational.
5.2. Turning The Instrument Off
Hold down the [MODE] key through the “5…4…3… 2… 1… Power Off” sequence. The monitor is
off when the display is blank. Release the [MODE] key.
The instrument is now off.
5.3. Low Battery Indicator & Action
The internal battery is designed for up to 2 months’ continuous operation in STD mode (MeshGuard
LEL IR only), and the external battery for up to 4 months when powering the MeshGuard LEL IR,
up to 80 days when powering the MeshGuard CO2 IR. When the battery gets low, the instrument’s
alarm beeps once per minute. It is recommended that the battery be changed immediately, to
minimize disruption.
When the battery is completely depleted, the LCD displays “OFF,” and the LED and buzzer alarms
activate once per second. The battery icon also blinks on and off. The instrument shuts down after
you press any key, or shuts down automatically if you do not press a key for 60 seconds.
.
5.4. Over Range Alarm
When a gas concentration exceeds 100% of LEL or 5% of CO2, the instrument displays “OVR” and
its buzzer and LED are activated.

MeshGuard LEL IR & CO2 IR User’s Guide
17
5.5. Wireless Communication Indicator
When wireless communication is turned on, the LCD displays the wireless link status in
the upper left corner:
If the instrument finds and joins a wireless network, an antenna icon is shown in the
display. If no link or a weak link is established, no antenna icon is shown. Press [Y/+] to
manually search for a network.
In RTR mode, the antenna icon flashes on and off, indicating that the modem is always
active and transmitting. With an external RAE BatteryPak, the MeshGuard LEL IR can run
for up to 45 days, the MeshGuard CO2 IR up to 40 days.
In STD mode, the antenna icon is shown continuously (solid), indicating that the modem is
active whenever alarm data is transmitted. This conserves battery power. With an external
RAE BatteryPak, the MeshGuard LEL IR can run for up to 4 months, the MeshGuard CO2
IR up to 80 days.
5.6. Operation Modes
The instrument can operate in Standard (STD) or Router (RTR) mode. In STD mode, it transmits
data to the host at a set interval (the default is 30 seconds) or anytime an alarm occurs. In RTR
mode, the MeshGuard LEL IR or MeshGuard CO2 IR transmits data in real time, and it can also
work as a router as needed to relay data from STD devices back to the host.
Note: Operating in RTR mode reduces battery life. The transmission interval can be changed in
Programming Mode to extend battery life. See page 21 for details.
In addition, there is a Detection Mode for standard operation, Programming Mode for making
changes to values (such as the High Alarm, etc.), Diagnostic Mode (for servicing and checking the
sensor, etc.), and Diagnostic Programming Mode, which is for selecting between Standard (STD) &
Router (RTR) modes, etc.
The diagram on the next page shows how to enter and step through the menus in each mode.
