1 Introduction
1.1

Product overview

The Rosemount 975 series is based on proven technologies, including triple infrared (IR3)
and ultraviolet infrared (UV/IR). The Rosemount 975 series provides the fastest response
to fire, longest distance detection, and revolutionary UV/IR technology, coupled with
superior immunity to false alarms, functioning in harsh conditions with unparalleled
reliability and durability.
The series is suited to meet the challenges of wide range of industrial and commercial
applications with long distance and fast response detection, providing superior protection
of high value property and personnel to keep an eye on your safety.
Detection performance can be easily adapted to all environments, applications, and
requirements, by changing the detector's configuration parameters. Adjusting these
parameters, as well as performing other maintenance and monitoring tasks, is possible by
means of RS-485-based Modbus

Models

The Rosemount 975 Flame Detectors are electro-optical devices designed to identify fire
events, enabling alarm activation. The detectors are intended for indoor or outdoor use
and can be used stand alone or connected to an alarm/automatic extinguishing system.
The Rosemount 975 series comprises the following detectors:
Rosemount 975MR
The Rosemount 975MR, an ultra-fast multispectrum triple infrared (IR3) flame detector,
provides superior, longest distance detection of hydrocarbon fires at up to 295 ft. (90 m),
exceptional ultra-fast detection in under 50 msec, and unparalleled reliability. The
Rosemount 975 is based on proven IR3 technology, ensuring highest sensitivity with best
immunity to false alarms.
Rosemount 975HR
The Rosemount 975HR is a multispectrum IR flame detector that provides superior,
longest distance detection of hydrogen (at up to 165 ft. [50 m]) and hydrocarbon fires (at
up to 295 ft. [90 m]), exceptional ultra-fast detection in under 50 msec, and unparalleled
reliability. The Rosemount 975HR is designed to deal with the challenges of invisible fires
based on proven triple IR (IR3) technology, ensuring highest sensitivity with best immunity
to false alarms.
Rosemount 975UF
The Rosemount 975UF is an ultra-fast ultraviolet (UV)/IR flame detector, which is able to
detect in under 20 msec and features a unique dual sensor with selectable UV and IR
channels that can be used separately or combined. The detector is designed to detect a
range of fires, such as hydrocarbon-based fuel and gas, hydroxyl, hydrogen, metal, and
inorganic.
