RS-485 Overview

By using the RS-485 network capability of the IR3 detector and additional
software, it is possible to connect up to 32 detectors in an addressable
system with 4 wires only (2 for power and 2 for communication). Using
repeaters, the number of detectors can be much larger (32 detectors for
each repeater) up to 247 on the same 4 wires. When using the RS-485
network, it is possible to read each detector status (FAULT, WARNING, and
ALARM) and to initiate a BIT for each detector individually.

For more details, contact SPECTREX.
