RS-485 Overview

C.1 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 four (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 four (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 to each detector individually.

For more details, consult Sierra Monitor.
