BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 4 of 23 1. General description The Gas Trainer has been specially developed to safely simulate situations where the use of a four gas meter needs to be trained. No use is made of real gases; instead, transmitters (electronic beacons) are used to simulate a cloud of gas. As the transmitters are equipped with a field strength regulator, it is possible to simulate both large and small clouds of gas. The system is capable of simulating four different types of gas: - explosive gas (%LEL) - Oxygen (O2) - Hydrogen Sulfide (H2S) - Carbon Monoxide (CO) The trainee’s gas meter (Student Unit) measures the strength of the signal of the transmitters, thus simulating one of the four gases (selectable). An alarm sounds if the measured value exceeds the preset alarm value. Per gas type, two alarm levels can be set by the Instructor. The instructor also receives an alarm signal if one of the alarm values is exceeded. One gas type (user selectable on the Instructor Unit) will be simulated by the transmitters, the other three gases can be adjusted on the Instructor Unit. The Student Unit and Instructor Unit communicate with each other using a wireless link. The Student Unit will always follow the Instructor Unit’s settings for the three gases that are not simulated by the transmitters. The set consists of: 1 Gas Trainer Instructor Unit 1 Gas Trainer Student Unit 3 Gas Trainer transmitters 1 Gas Trainer measuring probe 1 AC/DC Power Supply 1 DC Power splitter cable 1 User Manual

BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 6 of 23 3. Use 3.1 Transmitters The transmitters form the source of the simulated cloud of gas. In order to control the size of the cloud of gas, all transmitters are equipped with a field strength regulator, allowing the range to be set. Positioning - Position one or more transmitters in the area in which the gas cloud is to be simulated. The control unit can be positioned out of sight, and the much smaller transmission points can be positioned inconspicuously, as long as the Student Unit can receive information from the transmission points. The best effects are achieved when all three transmitters are positioned in such a way that they combine to form a circle within which the gas cloud can be detected (figure 3.1). figure 3.1: Position the transmitters in a circle for the best results
BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 7 of 23 Operation Controls and indicator on the transmitter (figure 3.2): (1) Power indicator (Red) (2) Charger indicator (Green) (3) High setting (large gas cloud) (4) Low setting (small gas cloud) (5) Charging connector (6) Power switch Switching on - Push the left-hand switch upwards (6). The power indicator (1) will flash, and the set signal will be emitted. Field Strength The transmitter has two different field strengths, to be able to make larger and smaller gas clouds. High field strength - Push the right-hand switch upwards (3). The transmission points now have a range of approx. 8 meters (10% LEL) in an open space. The range is greatly dependent on reflections in the area. It is therefore possible for the range to vary in the vicinity of obstacles. Low field strength - Push the right-hand switch downwards (4). The transmission points now have a range of approx. 5 meters (10% LEL) in an open space. The range is greatly dependent on reflections in the area. It is therefore possible for the range to vary in the vicinity of obstacles. Switching off - Push the left-hand switch downwards (6). The indicator (6) will stop flashing, and the transmitter will stop emitting signals. figure 3.2: Controls of the Transmitter
BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 8 of 23 Charging - Connect the transmitter’s charging connector (5) to the battery charger and plug the wall adaptor in the wall outlet. The transmitter will then be switched off electronically, irrespective of the position of the on-off switch. The green charging indicator will start blinking. When the battery is full, the charging indicator lights continuously. When a battery is completely empty before recharging, the device will start a trickle charge cycle to prevent battery damage. The green charging indicator will immediately light continuously. Leave the charger connected, the charger will recover the battery in a safe way. After approximately four to six hours, the battery will be fully charged. A normal full charging cycle will take approximately 4 hours. The charging circuit continuously monitors the battery status and switches to trickle charge when the battery is fully charged. Generally speaking, it is sufficient to charge up all the transmitters at the same time as the Instructor Unit and Student Unit, to always have a working set. If the range of a transmitter becomes significantly weaker before the batteries of the Instructor Unit or Student Unit are empty, the battery power level is very low and must be charged up before continuing with the training. The transmitter is not equipped with a dedicated battery indicator. However, when the battery is empty, the power indicator will light continuously. The transmitter will not operate reliable anymore, the battery needs to be recharged.
BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 9 of 23 3.2 Student Unit Operation The Student Unit is operated by means of a single button, controlling all the functions of the gas meter.

BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 10 of 23 Measuring - Use the device to “search” for gases, as one would do with a normal gas meter. The meter will display a reading if the holder enters the area of range of a transmitter, or if the Instructor has manually changed a value. If one of the measurements exceeds the preset lowest alarm level A1, the meter will give a normal alarm signal; the optical alarms will flash in red and a sound will be emitted. If one of the measurements exceeds the preset highest alarm level A2, the meter will give a fast alarm signal; the optical alarms will flash fast in red and a faster sound will be emitted. The text of the gas causing the alarm will blink to indicate the cause of the alarm. An alarm will continue as long as one of the measurements is beyond the alarm limit. Taking measurements using an external measuring probe The supplied measuring probe can be used to take spot measurements. The built-in sensor is deactivated automatically when the probe is connected to the Student Unit’s connector (2). Measurements are then only taken using the probe. - Take the probe and connect the probe’s connector to the connector (2) of the Student Unit.

BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 18 of 23 4. Channel and language setup In order to use more than one set in the same area, the Gas Trainer set has eight different channels. Please note that these are so called software channels; every channel uses the same radio frequency using different Device ID’s. Therefore, using more than one set in the same area might result in a slightly slower response between Instructor Unit and Student Unit. The Gas Trainer set allows the user to set the language for indicating the explosive gas measurement. These options are available from the setup menu: • %LEL • %LIE • %UEG All settings are made on the Instructor Unit, and are then transmitted to the Student Unit. All Student Units within the reach of the wireless link will receive the settings, even if they are on a different channel. Upon reception of these settings, a Student Unit will ask the user to accept (press and hold the power button) or decline (press the power button shortly) these settings. Be sure to set up the settings correctly before accepting or declining them on the Student Unit. A Student Unit will only ask for confirmation once. If a user accidentally makes the wrong decision (e.g. declining instead of accepting), then leave the Instructor Unit in setup mode and switch the Student Unit off and on. The Student Unit will then ask for confirmation again. Entering setup menu on the Instructor Unit - Be sure that the Instructor Unit is switched off. - Press and hold the mode button. - With the mode button pressed, switch the device on. - Release the mode button. The setup menu will appear on the display. - Use the mode button to switch between language and channel. - Use the up and down buttons to change the value. - Leave the Instructor Unit in setup mode until you have confirmed the settings on the Student Unit Leaving setup menu on the Instructor Unit After the settings have been accepted or declined on the Student Unit (see next page), the user can leave the setup menu and go back to measurement mode. - Leave the setup menu on the Instructor Unit by pressing and holding the power button. The device will shortly show the BullEx logo and then return to measurement mode. figure 4.1: Setup menu on Instructor Unit

BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 20 of 23 Accepting or declining settings on the Student Unit Whenever a Student Unit receives setup information from any Instructor Unit in the neighborhood, the Student Unit will ask for confirmation by showing a settings menu on the display (figure 4.2). Since all Student Units in the neighborhood will receive this information, the user can either accept or decline these settings. The user can accept the settings by pressing and holding the power button on the Student Unit: - Be sure that the Student Unit is switched on and that you see the settings display - Press and hold the power button until the Student Unit goes into measurement mode The Student Unit now stores the received settings. The user can decline the settings by pressing the power button shortly on the Student Unit: - Be sure that the Student Unit is switched on and that you see the settings display - Press the power button shortly until the Student Unit goes into measurement mode The Student Unit doesn’t store the received settings and continues with the current settings. figure 4.2: Setup menu on Student Unit
BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 21 of 23 5. Inspection and maintenance In order to ensure trouble-free training sessions, we recommended that you regularly carry out the following checks, preferably before every training session: • Inspect the system for damage to the casing or cables. Do not use the system if the cables are damaged or if the casing is damaged to such an extent that one could expect the system not to function properly or to pose a potential safety risk to the student or instructor. In that case, contact the manufacturer and have the system repaired. • Check the proper functioning of the system. Switch on one transmitter, and use the Student Unit to check that it is working properly. At the same time, check whether the measured value is being sent to the Instructor Unit. Then do the same for the other transmitters. • Make sure that the system is adequately charged when starting a training exercise. Low battery power can give rise to unwelcome training interruptions. • The usable lifetime of the batteries is limited. An average battery will last for 1 to 2 years. If the length of time that one can work with the unit on a fully charged battery diminishes noticeably, then we recommend that you have the batteries replaced. In order to get maximum benefit from the system, we recommend that all the batteries are replaced at the same time. The batteries will also last longer if you use the system regularly, and regularly recharge the batteries. If the system is not used for a period of one month or longer, you should completely charge the set before using it.
BullEx USER MANUAL Gas Trainer PROTOTYPE! Page 22 of 23 6. Precautions and safety instructions • The Gas Trainer system is a simulation system. For reasons of safety, the system does not detect gas but ultrasonic signals. The system therefore cannot be used as a real gas meter. Do not use the system in an environment in which you suspect that there may actually be a potentially explosive mix of gases! • The system is not waterproof. Never use it in the rain or in places where fire-extinguishing materials are used. Contact with water may permanently damage the system, in which case any resulting damage will not be covered by the product guarantee. • Never use the system if the casing or cables are damaged and if you suspect a potential risk for the instructor or trainee. In this event, contact the manufacturer and have the system repaired. • If necessary, clean the equipment with a damp cloth (using a mild all-purpose household cleaning agent if necessary). The casing is not resistant to chemicals such as alcohol, thinner or acetone. • If no units are being charged, disconnect the battery charger from the mains power. • Once the training session has been completed, it is best to store the set back in the supplied carry case. You can thus be sure that the system will be well protected. 7. Guarantee From date of purchase, the Gas Trainer system carries a year's full guarantee on materials, call out charges and hourly rates. Defects caused by wrongful use, damage caused by falling or external factors that damage the Gas Trainer system are not covered by the guarantee.

If you have any doubts, please feel free to contact HAAGEN Fire Training Products. Problem: Possible solution: The Student Unit is not detecting anything from the transmitters Check whether all the transmitters set out are switched on. Check whether all the power LEDs on the transmitters are flashing. If the LED is not flashing but the device is switched on, the transmitter’s battery power is probably too low. Charge the transmitter and try again. If the problem persists, contact the manufacturer. The Instructor Unit cannot detect the Student Unit, although both devices are switched on. The Instructor Unit is not showing the measured values on the Student Unit. Check whether both devices are set to the same channel. Check whether both batteries are sufficiently charged, and check whether both devices are within range. For the purposes of this test, hold them less then two metres apart. Switch off both devices and then switch on the Instructor Unit first, followed by the Student Unit. If the problem persists, contact manufacturer. Either the Instructor Unit or the Student Unit is not responding to the button being pressed, or one of the units is showing strange symbols on the display. Connect the device to the battery charger for at least five minutes, then disconnect it and switch the device back on. When switching on the Instructor or Student Unit, it shows the BullEx logo, but then immediately switches itself off The battery is completely empty and the device switches itself off in order to prevent battery damage. Recharge the unit completely using the battery charger and try again. If the problem persists, contact manufacturer.
