Introduction
To comply with local standards and jurisdictional authorities, perform end-to-end loop
testing of fire protection alarm systems, including detectors, periodically. Many safety
authorities and plant managers of high value/high risk assets and facilities insist on
quarterly end-to-end testing of their entire fire protection systems using an external flame
simulator.
Rosemount Flame Simulators emit electromagnetic radiation in a unique sequential
pattern corresponding to and recognizable as fire by the specific Rosemount 975 Flame
Detector. This allows the detector to be tested under real fire conditions without the
associated risk of an open flame.
Rosemount Flame Simulators are ATEX certified EExd for use in Zone 1 and Zone 2
hazardous areas and are powered by rechargeable lithium ion batteries. When fully
charged, the flame simulator will operate for at least 100 tests without recharging.
The Rosemount Flame Simulator is the only non-hazardous and safe method to test the
flame detector's sensors, internal electronics, alarm activation software, cleanliness of the
viewing window/lens, wiring integrity, actual relay activation, and proper functionality of
any other outputs used (mA, RS-485, or HART

Features and benefits
•
Used for maintenance and testing of flame detectors.
•
Can activate the flame detector from a distance of 23 ft (7 m).
•
Includes rechargeable battery.
•

1.3
Principles of operation
The simulator includes a reflector which accumulates the infrared energy and directs it
towards the detector. The Rosemount FS-UVIR-975 also includes a sight in order to point
the simulator to the center of the flame detector.
