FMC2000 Controller MeshGuard
MeshGuard RTR & STD Modes
MeshGuard can operate in either Router Mode (RTR) or Standard Mode (STD). In RTR, the modem is always on and data is constantly
exchanged with the FMC2000, plus the MeshGuard can act as a router to extend the range between MeshGuards and the FMC2000.
In STD mode, the MeshGuard's modem is usually off, conserving power. The modem is turned on when an alarm occurs, plus it is
turned on periodically to transmit data when no alarm is sounding. This keeps the FMC2000 informed of its online/offline status.
Note: When in STD mode, battery life in a MeshGuard EC is up to 6 months. In RTR mode, the battery life in a MeshGuard EC is up to
10 days.

Standard Network
In a typical "star" configuration,
MeshGuard monitors are in Standard
Mode (STD) and only communicate
with the FMC2000. The MeshGuards
in the network do not communicate
with each other or act as routers.
Network Configurations Using The
®
FMC2000 Controller & MeshGuards
The hub of any MeshGuard network is the FMC2000 wireless controller,
which can act as the wireless base station for up to 24 MeshGuard
monitors. Housed in stainless steel and equipped with a backup battery,
the FMC 2000 is the ideal controller for MeshGuard systems used on
drilling rigs and during plant maintenance operations requiring gas
detection. Dependable and simple to install and operate, a MeshGuard
network can be configured and reconfigured mostly by just physically
relocating MeshGuard detectors.

RTR
Mesh Network
In a mesh network, MeshGuards set in
Router Mode (RTR) are capable of com-
municating not only with the FMC2000
base station, but with each other, so that
obstacles are more easily overcome, and
if any monitors go offline, the network
"heals" itself. Finally, when a MeshGuard
is in RTR Mode, its modem is always on,
so real-time data is always being deliv-
ered to the FMC2000.

Hybrid Network
Because the FMC2000 can communi-
cate with MeshGuards in both RTR and
STD modes simultaneously, multiple
"subnetworks" and mixed networks can
be used. The example shown here has
four "subnetworks," with the MeshGuards
in RTR Mode acting as routers for those
in STD Mode, as well as providing real-
time data to the FMC2000 at all times.
