FlameSpec IR3-H2-HD User Manual F140V0020.03 1. Introduction The FlameSpec-IR3-H2-HD flame detector provides ultra-fast response, high performance and reliable detection of hydrogen (H2) fires. The detector addresses slow growing fires as well as fast eruptions of fire using improved IR3 technology. The detector operates in all weather and light conditions.
FlameSpec IR3-H2-HD User Manual F140V0020.03 1.2 Model Number Description Model No are defined as follows: FLS-IR3-H2-HD - X S X 1 1 - M25 2 - ¾” NPT A – FM, ATEX 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.
FlameSpec IR3-H2-HD User Manual F140V0020.03 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.

FlameSpec IR3-H2-HD User Manual F140V0020.03 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 2 ft. (0.5m) 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.
FlameSpec IR3-H2-HD User Manual F140V0020.03 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.

FlameSpec IR3-H2-HD User Manual F140V0020.03 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.
FlameSpec IR3-H2-HD User Manual F140V0020.03 3.1 Sensitivity The detector can be configured to one of four sensitivity levels: low, medium, high and extreme. The following table lists for each sensitivity setting the maximum distance, in which a standard H2 fire would be reliably detected.
NTSC or PAL format, depending on the “Video analog output” setting. 3.7 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.
FlameSpec IR3-H2-HD User Manual F140V0020.03 4 Detector Wiring WARNING The sensor module in the front half of the detector contains no serviceable components and should never be opened. The terminal compartment at the back is the only part of the housing that should be opened by the user.

FlameSpec IR3-H2-HD User Manual F140V0020.03 5 Operation The FlameSpec-IR3-H2-HD is a triple-IR flame detector that includes a built-in high-definition video camera module. The video module automatically records video of alarm events, and can provide live video of the detection zone to a screen in the control room.
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).
