4 Operating The MeshGuard

Make sure the battery is installed before operating the MeshGuard. Refer to page 39 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”).

MeshGuard User’s Guide

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 the icon is not shown; press [Y/+] to search for a network). The current gas concentration reading is also displayed:

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.

MeshGuard User’s Guide

4.3 Low Battery Indicator & Action

The battery is designed for up to six months’ life in RFD mode. When the battery gets low, the MeshGuard beeps once per minute. It is recommended that the battery be changed immediately, to minimize disruption.

When 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.

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.

A flashing antenna means the MeshGuard is in Full Function Mode (FFD), and the radio is always on.

MeshGuard User’s Guide

5 Operation Modes

The MeshGuard can operate as a Reduced Function Device (RFD) or a Full Function Device (FFD). In RFD mode, the MeshGuard transmits data to the host at a set interval (the default is 30 seconds) or anytime an alarm occurs. In FFD mode, the MeshGuard receives data in real time, and it can also work as a router as needed to relay data from RFD devices back to the host.

Note: Operating the MeshGuard in FFD mode reduces battery life.

The interval can be changed in Programming Mode. See page 18 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 the sensor type, etc.

11 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 MeshGuard from damage in industrial settings.

11.1 Magnet-Mount Installation

Magnet For Mounting MeshGuard

Rear of 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.

MeshGuard User’s Guide

11.2 Fixed Installation

Four reinforced holes in the rear of the enclosure allow for a screw to pass through to the mounting brackets.

The enclosure can be mounted to a vertical or horizontal pole.

ertical pole Horizontal pole

MeshGuard User’s Guide

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.

MeshGuard User’s Guide

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.

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.

MeshGuard User’s Guide

11.3 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.
