Page 6: Introduction
FlameSpec IR3 User Manual F120V0020.05 1. Introduction The FlameSpec-IR3 flame detector provides ultra-fast response, high performance and reliable detection of all types of hydrocarbon fires (visible and non-visible). The detector addresses slow growing fires as well as fast eruption of fire using improved Triple IR (IR3) technology. It operates in all weather and light conditions with highest immunity to false alarms. -
Page 7: Internal Tests
FlameSpec IR3 User Manual F120V0020.05 1.3 Internal tests During normal operation, the flame detector performs self-tests of its optics, electronics and software. These include a periodic BIT (Built-In-Test) in which the sensors and window cleanliness are tested. Any detected fault is indicated as shown in Table 4 (in section 5.1). -
Page 8: Installation
FlameSpec IR3 User Manual F120V0020.05 2 Installation The detector is intended for use as part of a complex system where many detectors and other devices are integrated with different vendors’ systems and interface communication to a variety of different types and configuration control units and panels including control of instrumentations computers. - Page 9 FlameSpec IR3 User Manual F120V0020.05 Environment ▪ Environmental conditions including but not limited to dust, snow or rain can reduce the detectors sensitivity and require additional maintenance. Welding ▪ Arc welding should not be performed within 15 ft. (5m) of the detector. It is recommended that the system be inhibited during welding operations in situations where the possibility of a false alarm cannot be tolerated.

Page 10: Preparations For Installation
FlameSpec IR3 User Manual F120V0020.05 2.2 Preparations for Installation The installation must comply with local regulations and standards applicable to flame detectors (e.g., NFPA 72) and all local and common engineering practices. It is recommended to consult with a safety engineer. - Page 11 FlameSpec IR3 User Manual F120V0020.05 • The equipment is certified for use in ambient temperatures in the range of -67°F to +167°F (-55°C to +75°C) or -67°F to +185°F (-55°C to +85°C) and should not be used in temperatures outside this range.

FlameSpec IR3 User Manual F120V0020.05 3 Configuration options Some functions of the detector can be configured using an RS-485 modem connected to a computer with the “FDG communicator” software. These configuration options are listed in the following table along with their factory default values. -

3.6 Modbus Address The detector can communicate with the “FGD communicator” software using a Modbus RTU compatible protocol on RS-485. This protocol allows for a network of detectors to be connected, each with a unique Modbus address. The address of the detector can be set to any value in the range 1–247. -

Page 21: Operation
FlameSpec IR3 User Manual F120V0020.05 5 Operation The FlameSpec-IR3 is a triple-IR flame detector ready for detecting fire approximately 30 seconds after power up. During this startup time the LED flashes Yellow. If the startup is successful, the indication LED turns to green, the 0-20mA indicates 4mA and the fault relay is closed. -
Page 22: Testing
The BIT process runs automatically at startup and periodically during the operation of the detector. The BIT can also be initiated manually by short circuiting the “Manual BIT” terminal and the “24 VDC (-)“ terminal for one second (see Table 3) or by using the FGD communicator software (connected through RS-485). -
