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.

Operation
4 Operating The MeshGuard
Make sure the battery is installed before operating the MeshGuard. Refer to page 34 for information on battery
installation and replacement.
4.1 Turning The MeshGuard On
Hold down the [MODE] key and release it when the MeshGuard beeps. The monitor is now on, as indicated by the
display:
The MeshGuard performs a self-test, followed by warm-up and zero calibration. 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 MeshGuard initializes the wireless network and displays this information:
Note: If MeshGuard is unable to find a radio network to connect with, it searches, and the display alternates
between “rdo” and “Srh” (for “radio search”).
Page 12
MeshGuard User’s Guide
12
Next, the display tells you that MeshGuard is initiating network communication:
Next, if a network is located, an antenna icon appears (if no network is found, then refer to “Join Mesh Network” on
page 27). The current gas concentration reading is also displayed:
Note: When adding a MeshGuard detector to a new network for the first time, it is recommended that you press
[Y/+] to manually initiate a search for the network.
The MeshGuard is now operational.
4.2 Turning The MeshGuard Off
Hold down the [MODE] key through the “5…4…3… 2… 1… oFF” sequence. The monitor is off when the display is
blank. Release the [MODE] key.
The MeshGuard is now off.
4.3 Low Battery Indicator & Action
The MeshGuard’s battery is designed for up to six months’ life in STD mode (in RTR mode, including the
MeshGuard Router’s normal operation, battery life is up to 10 days). When the battery gets low, the MeshGuard
beeps once per minute and an empty battery icon appears. 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, buzzer and vibration alarm activate
once per second. The battery icon also blinks on and off. The MeshGuard shuts down after you press any key, or
shuts down automatically if you do not press a key for 60 seconds.
Page 13
MeshGuard User’s Guide
13
4.4 Wireless Communication Indicator
When wireless communication is turned on, the LCD displays the wireless link status in the upper left corner:
If the MeshGuard 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 search for a network. (See “Join Mesh Network” on
page 27.)
A flashing antenna means the MeshGuard is in Router Mode (RTR), and the radio is always on.
5 Operation Modes
The MeshGuard can operate as a standard (STD) or a router-mode (RTR) device. In STD mode, the MeshGuard
transmits data to the host at a set interval (the default is 30 seconds) or anytime an alarm occurs. In RTR mode, the
MeshGuard receives 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 the MeshGuard in RTR mode reduces battery life.
The interval can be changed in Programming Mode. See page 13 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 STD & RTR modes, etc.

5.2 Manually Sending Data
While the MeshGuard typically sends reading data to the network on a fixed interval, you can send the data anytime.
When the monitor is connected to the network, press the [Y/+] key. The screen displays “Ini” and “nEt” one time,
and the monitor sends the current sensor data, and returns to the detector reading.
5.3 Detection Mode (When Portable Mode Is Enabled)
When Portable Mode is enabled (see page 32), pressing [MODE] steps through three more screens, STEL, TWA,
and Peak:
The initial screen is the reading display:
Press [MODE], and it displays STEL. The STEL (short-term exposure limit) is the average reading of the gas
concentration for the last 15 minutes.
Note: The STEL reading does not appear until 15 minutes have elapsed. If the MeshGuard has not been on for 15
minutes, it displays three dashes:
Page 16
MeshGuard User’s Guide

10 Appendix A: Installation
Two methods for mounting MeshGuard make it easy to install. The first method uses a magnet that screw onto the rear of
the MeshGuard, making ideal for moving from one location to another. The second method uses a specially designed
stainless-steel enclosure that is permanently mounted. It protects the plastic-body MeshGuard from damage in industrial
settings.
10.1 Magnet-Mount Installation
For
Mounting
MeshGuard
This magnet is powerful enough to support the MeshGuard when it is placed against a flat steel or iron surface.
Important! Keep the magnet away from computer hard drives. The strong magnet can corrupt or erase data on these.

Slip the screws through the two holes that are side by side in order to mount the enclosure to a vertical pole.
Otherwise slip the screws through the two vertically aligned holes to attach the enclosure to a horizontal pole.
Loosely assemble the clamp parts around the pole. Note that the screws have nuts that fit into the clamp parts. The
clamp parts are designed to hole the nut so that you do not need to use a wrench. Hand-tighten the parts until snug.
Tighten the hex screws from the front of the enclosure:
Once the clamp parts and the enclosure are securely held against the pole, stop tightening.
Note: The pole must be between 25mm (1″) and 63mm (2.5″) in diameter.

Next, place the MeshGuard into the enclosure:
1. Lift up the hinged cover of the enclosure.
2. Slide the MeshGuard into the enclosure from the top.
3. Close the cover of the enclosure.
4. Insert the hex screw into the cover’s locking portion, and tighten it.
5. The MeshGuard is now ready to use.
MeshGuard User’s Guide
Note: The sensor cover on the bottom of the enclosure can be removed so that the filter and sensor can be
inspected without removing the MeshGuard from the enclosure. Simply pull off the cover and follow the
maintenance procedures in this guide.

10.3 Magnetic Mount Alternative Installation
The magnet-mount disc can be attached to the steel enclosure instead of the clamps. This approach provides the
protection of the enclosure with the ease of installation afforded by the magnetic mounting.
1. Insert screw through magnetic disc.
2. Place the magnetic disc over the bottom hole on the rear of the enclosure.
3. Tighten the screw until the disc is snug.
