1.2 Product recycling/disposal
Recycling of equipment and packaging should be taken into consideration and disposed of in accordance
with local and national legislation/regulations.
1.3 Scope
Digital communication with the Rosemount 975 Flame Detector allows the operator to monitor the
status of the detector, determine factory settings and initiate field tests.
This document provides guidance for establishing HART communication and
structure when using the Rosemount 975 Flame Detector with a HART Handheld
computer, or another process interface device that supports Device Description Language (DDL).
1.4 Purpose
This manual is designed for use by system integrators and end users to compliment other
documentation (for example, the user manual for your Rosemount 975 Flame Detector) by providing a
complete, unambiguous description of the HART Host Application and Communication.
1.5 Reference documents

2.1 Rosemount 975 Flame Detector Product Overview
The Rosemount 975 Series Flame Detectors are a family of Flame Detectors that incorporate advanced
optical spectral analysis of flames. Rosemount 975 Flame Detectors operate reliably in the harsh
conditions of offshore drilling and production platforms, FPSO vessels, fuel loading facilities, LNG and
LPG plants, oil refineries, aircraft hangars, paint spray booths, gas turbine power stations, chemical and
petrochemical plants.
Rosemount 975 Flame Detectors employ the latest UV/IR (Ultra Violet & Infrared), and IR3 (Triple IR
patented multi-spectrum detection) Flame Detection technologies.
Depending on the specific model, the Rosemount 975 Flame Detector may include the following
interfaces: 4-20mA current output, HART communication, relays, RS485 ModBus communication,
status LEDs.
