8 | 87 Product and Variant concept SafEye 950 & 960: Flash Source unit (Tx) – 3 for different distances:  Tx for 5 up to 20m  Tx for 15 up to 40m  Tx for 35 up to 80m The UV Source unit emits UV radiation pulses at the rate of pulse per second. The front of the source has a internal reflector that collimates the UV beam for maximum intensity. The sources models have the same electronics and optical device. The only difference is in the apparatus. Toxic Open Path Gas Detector SafEye 950 & 960 SafEye 950 & 960 Models and Types

9 | 87 Product and Variant concept SafEye 950 & 960: Detector unit (Rx) – 2 for different gases:  SafEye 950 for Hydrogen sulfide (H 2 S)  SafEye 960 Ammonia (NH 3 ) The Detector receives the transmitted pulsed radiation signals from the UV Source. The signals are then amplified and fed into an analog to digital signal converter to be processed by the internal microprocessor. When the signals drop below a prescribed level, the internal microprocessor will compensate for them. This will allow the signal to be maintained even in severe weather conditions. The data is sent to the output interface section. In the UV band, H 2 S has characteristically strong absorption in the solar blind range of 189–270 nm and NH 3 within the range of 189 - 210 nm. Aromatic Hydrocarbons such as Benzene, Toluene, Xylene, Styrene, etc., have the unique “conjugated double bonding” chemical configuration responsible for their spectral absorption in the UV band. In the UV band, the aromatic compounds have a typically strong absorption in ranges of 200 –230 nm and 250-270 nm. Toxic Open Path Gas Detector SafEye 950 & 960 SafEye 950 & 960 Models and Types

Operational Modes: Maintenance Call Mode (3 mA Output) The Maintenance Call Mode indicates a low signal or low signal ratio that may be caused by a dirty window, misalignment, poor source, or one of the Detector’s parameters is at the “limit” value. The Detector continues to function and reads any gas present, but provides a (3 mA) pre-warning signal that a maintenance procedure is required. Zero Calibration Mode (1mA Output) This mode calibrates the base level from which the Detector read gas to zero. It should only be performed in the following situations:  There are no combustible gases present  A clear path exists between the UV Source and Detector  Clear weather conditions are present Zero Calibration must be performed after installation, re-alignment and window cleaning, by using the handheld unit, Host software on PC or the magnet. Toxic Open Path Gas Detector SafEye 950 & 960 SafEye 950 & 960 Features & Functions

Fault Modes In Fault Mode, there are three fault types:  Fault 1 (2 mA Output): Non critical This occurs due to a blockage, very low signal or partial obscuration, or full beam block. In this situation, detection is no longer possible. The Detector’s proper operation can be restored (Auto reset) during operation if the condition causing the problem is removed or resolved. This mode occurs after a delay of 60 sec. from the moment of the fault. This delay is important to eliminate momentary obscuration due to an object/person passing through the beam.  Low Voltage Fault (1 mA Output) In this situation, detection is disabled due to low voltage being supplied to the Detector. The Detector returns to proper operation only when proper voltage level restored.  Fault 2 (1 mA Output): Critical In this situation, the detection is disabled due to an electrical/software operational failure or a central device (memory, processor) fault. Such a fault causes the Detector to cease operation. If there is a fault in the 0-20 mA loop, the output is 0 mA. Toxic Open Path Gas Detector SafEye 950 & 960 SafEye 950 & 960 Features & Functions

Installation Guidance: The Source (Tx) and Detector (Rx) The appropriate Detector should be selected for the length of open path to be monitored. To allow for ageing of the Source and a reduction of the UV signal due to adverse weather, we recommend using a Detector that is not at the limit of its operating range. The open path between the Source and Detector, and the immediate surroundings, should be kept clear of obscuration that might hinder the free movement of air in the protected area or block the infrared beam. Guidance Tips for Gas Detector Locations The following are guidance tips for gas detector locations, in order to provide the best detection coverage:  For heavier than air gases: below potential leak source  For lighter than air gases: above potential leak sources  Along the expected leak trajectory: near to leak sources, taking into account prevailing wind directions  Between leak source and potential ignition sources  In areas with expected heavy fog, rain or snow, consider the effect of long range installation and install the Detector at a shorter range, with the maximum intensity model available.

Use the following certification instructions:  The cable entry point may exceed 182°F (83°C). Suitable precautions should be taken when selecting the cable.  The equipment may be used with flammable gases and vapors with apparatus groups IIA and IIB +H2 T4 in the ambient temperature range -67°F (-55°C) to +149°F (+65°C).  Installation should be carried out by suitably trained personnel, in accordance with the applicable code of practice e.g. EN 60079-14.  Inspection and maintenance of this equipment should be carried out by suitably trained personnel, in accordance with the applicable code of practice e.g. EN 60079-17. Toxic Open Path Gas Detector SafEye 950 & 960 Installation & Commissioning

Wiring: For wiring, use color-coded conductors or suitable wire markings or labels. The wire cross-section must be between 1 mm² to 2.5 mm² (18- 14 AWG). The selected wire gauge should be based on the number of Detectors used on the same loop, and the distance from the control unit. The maximum number of wire connections in one terminal is two (2) wire cross-sections, each of 1 mm². Conduit/Cable Installation The conduit and cable installation must comply with the following guidelines:  To avoid water condensation in the Detector, install it with the conduits/cable entries facing downwards.  Use flexible conduits/cables for the last portion that connects to the Detector.  When pulling the cables through the conduits, ensure that they are not tangled or stressed. Extend the cables about 12 inches (30 cm) beyond the Detector location to accommodate wiring after installation.  After the conductor cables have been pulled through the conduits, perform a continuity test. To fully comply with EMC directive and protect against interference caused by RFI and EMI, the cable to the detector must be shielded and the detector must be grounded. The shield should be grounded at the detector end. Toxic Open Path Gas Detector SafEye 950 & 960 Installation & Commissioning

Toxic Open Path Gas Detector SafEye 950 & 960 Installation & Commissioning 1.Switch from ‘Normal’ to ‘Alignment’ mode indication. 2.Switch from ‘Alignment’ to ‘Standby’ mode. 3.Switch from ‘Standby’ to ‘Zero Calibration’ mode.  The 0-20mA output should now be at 1mA.  Wait up to 60 seconds until it switches to ‘Normal’ mode.  The detector reading is now set to normal.  The 0-20mA output should now indicate 4mA. Magnet Switching from each position (first three instructions below) can be done by HOST HART or RS485, or by moving the magnetic mode selector above the magnetic switch (see sketch).

Functional Check : The Functional Check Filter is a convenient operational check used to confirm that the response has not changed from previous readings. The filter is not used for calibration, since it is not necessary in the procedure, nor does it equate to a particular quantity of gas. Toxic Open Path Gas Detector SafEye 950 & 960 Installation & Commissioning Notes: 1.This functional verification procedure is for a standard 0-20 mA output. 2.Prior to starting the Functional check, verify that the power to the units is on, and that the current of the 0-20 mA channel is stable. Record the reading. To perform the functional check: 1.Position the Functional Check Filter in front of the SafEye Detector. 2.Center the Functional Check Filter’s window over the viewing window of the Detector. 3.Wait 20 seconds. 4.Read the 0-20 mA current. Determine the difference between the reading taken with and without the Functional Check Filter. This difference is the 0-20 mA current variance. 5.Record the 0-20 mA current variance in the Maintenance Logbook. If the variance is more than a 30% change when compared to the previous check (see delivery form), repeat the alignment. Caution: Do not allow automatic activation, and disconnect any external device that should not be activated during the Calibration check.

Maintenance & Troubleshooting General Maintenance SafEye Quasar 950/960 requires only simple periodic maintenance to provide satisfactory service and achieve maximum performance. The Detector and Source units can be maintained with the use of common tools and equipment. Record the periodic test results in a Maintenance Logbook with a copy of the delivery form inside. Note: Inspection and maintenance of this equipment shall be carried out by suitably trained personnel in accordance with the applicable code of practice such as EN 60079-17. Periodic Maintenance It is recommended that the Source and Detector viewing windows be kept as clean as possible, as it is an active device. Perform proper maintenance periodically to allow the SafEye system to retain maximum performance and reliability. To perform periodic maintenance:: 1.Perform alignment procedures each time that the Source or the Detector unit has been opened or moved for any reason. 2.The Signal Verification Check corroborates the current signals from the UV Source compared to that of previous alignments. It is recommended to perform this check every 6-12 months. The signal should be checked according to threshold levels. 3.Perform the Functional Check every 6 months 4.Perform the alignment procedure only if the signals are below threshold value 5.Perform Zero Calibration every time the Detector or Source is realigned or the windows are cleaned. Note: The frequency of cleaning operations is ultimately dependent upon the existing environmental conditions and the application. Toxic Open Path Gas Detector SafEye 950 & 960 Testing & Maintenance

63 | 87 Routine Optical Surface Cleaning To clean the optical window, proceed as follows 1. Turn off the power to the SafEye detector and source. 2. Where dust or dirt has accumulated, clean the optical surface with a small, soft-bristle brush. 3. The surfaces must then be washed thoroughly with water and a mild non-abrasive detergent. 4. Thoroughly rinse the glass surface with clean water; ensuring no residue is left behind. 5. Dry the glass with a clean dry soft cloth. 6. Enter in the maintenance logbook: date, name of person and company who performed the maintenance service. 7. Turn on power to the SafEye detector and source. 8. Perform signal verification. 9. Perform zero calibration. 10. Perform functional check. Note: Maintenance should be performed by suitably qualified personnel, who are familiar with local codes and practice. Maintenance requires ordinary tools. Toxic Open Path Gas Detector SafEye 950 & 960 Testing & Maintenance

64 | 87 Maintenance & Troubleshooting Signal Verification The Signal Verification check determines the proper operation of the open path. It checks the alignment and cleanliness of the window or any problem in Source or Detector. Use the PC Host software to measure the signal verification. Functional Check of Unit The SafEye Quasar has been calibrated at the factory per the user’s specific gas or vapor detection requirements. This procedure validates the functional operation. The functional check should be performed periodically. To perform the functional check: 1.Position the Function Check Filter in front of the SafEye Detector. 2.Center the Function Check Filter’s window over the viewing window of the Detector. 3.Wait 20 seconds. 4.Read the 0-20 mA current. Determine the difference between the reading taken with and without the Function Check Filter. This difference is the 0-20 mA current variance. 5.Record the 0-20 mA current variance in a Maintenance Logbook. If the variance is more than a 30% change when compared to the previous check (see delivery form), repeat the alignment. Caution: Do not allow automatic activation, and disconnect any external device that should not be activated during the Calibration check.

It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at −33.3 °C (−27.94 °F), and freezes at −77.7 °C (−107.86 °F) to white crystals. Combustion - when mixed with oxygen, it burns with a pale yellowish-green flame. At high temperature and in the presence of a suitable catalyst, ammonia is decomposed into its constituent elements. Ignition occurs when chlorine is passed into ammonia, forming nitrogen and hydrogen chloride; if chlorine is present in excess, then the highly explosive nitrogen trichloride (NCl 3 ) is also formed.
