RS-485 Overview

By using the RS-485 network capability of the Multi IR 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.
