10.1 LonWorks
®
Installation
Midas
®
can be directly integrated within a LonWorks
®
network using an optional interface module (MIDAS-
T-LON). This gateway provides both power and
communications to the Midas
®
transmitter and
creates a LonWorks
®
node on the network. All
gas readings, faults and other sensor data are
transmitted via the LonWorks
®
protocol. Any Midas
®
transmitter can be easily configured to connect with
the LonWorks
®
interface module.
The Midas
®
LonWorks
®
interface module is installed
behind the standard Midas
®
gas detector as shown
in Diagram 10-1. Power and data connections are
supplied directly to the LonWorks
®
interface module.
All power to the Midas
®
unit is provided via the
LonWorks
®
interface.
