A.4 LONWORKS COMMUNICATIONS BOARD
When fitted to a Transmitter Unit the LonWorks communications board provides an interface
between the unit and an open LON standard network.
The board consists of a Neuron micro-processor and associated memory and logic interface
components. Isolation to the network and correct signal levels are provided by an FTT-10A
transceiver device.
A.4.1 LonWorks Network Variables
The LIFELINE II gas detector has fourteen Network variable outputs, two network variable inputs
and four network configuration inputs as shown in the following LonMark Object Diagram.
Some or all of these may be bound to a LonWorks network. Descriptions of each variable are given
in the subsequent sub-sections. For more information consult Honeywell Analytics.
