    • Recessed on a wall or ceiling

    • Surface mounted

    • On a rigid Junction Box

    • All of the above

    Correct Answer

    VLQ Configuration options:

    • DIP Switch settings

    • VSC Software

    • QSC Software

    • Option A & C

    Correct Answer
    A. Option A & C
    Explanation
    The correct answer is Option A & C. This means that the VLQ configuration options include both DIP switch settings and QSC software. DIP switch settings are physical switches that can be toggled to configure certain settings on the device. QSC software, on the other hand, refers to the software provided by QSC that allows for further customization and configuration of the VLQ. Therefore, by selecting both Option A (DIP switch settings) and Option C (QSC software), you are able to fully configure the VLQ according to your needs.

    DIP switches on VLQ:

    • Set detector parameters

    • Over-ride software settings

    • Are over ridden by QSC

    • Option A & C

    Correct Answer
    A. Option A & C
    Explanation
    The DIP switches on VLQ are used to set detector parameters and can be over-ridden by QSC. This means that both option A and C are correct. The switches allow for manual adjustment of the detector settings, overriding any software settings that may be in place. Additionally, the QSC has the ability to override these manual settings if needed.

    How do you correct fault 47?

    • Measure Power supply Voltage

    • Check sample hole size and number

    • Clean the pipes if dirty

    • Option B and C

    Correct Answer
    A. Option B and C
    Explanation
    To correct fault 47, you need to check the sample hole size and number as well as clean the pipes if they are dirty. This implies that both option B and C need to be performed in order to fix the fault.

    How do you log into VLQ?

    • No Log on necessary

    • PC using QSC

    • Options B & D

    • Display Panel

    Correct Answer
    A. Options B & D
    Explanation
    The correct answer is Options B & D because logging into VLQ can be done either through a PC using QSC or through the Display Panel. No log on is necessary, so option A is incorrect.

    On the Display when is “Sb” displayed:

    • When Standby mode is enabled

    • Shortly before power up

    • During airflow normalization

    • During Auto learn

    Correct Answer
    A. When Standby mode is enabled
    Explanation
    When "Sb" is displayed on the display, it indicates that the Standby mode is enabled. Standby mode is a state where the device is powered on but not actively performing any tasks. It is a low-power mode that allows the device to conserve energy while still being ready to be used. Therefore, when the device is in Standby mode, the "Sb" message is displayed on the screen to indicate this state to the user.

    Connecting to VLQ with QSC software is done by?

    • Plug the USB lead to a running VLQ

    • Run Software and select correct coms port

    • Option A then B

    • 9 pin serial lead

    Correct Answer
    A. Option A then B
    Explanation
    To connect to VLQ with QSC software, the first step is to plug the USB lead into a running VLQ. Then, the software needs to be run and the correct coms port should be selected. Therefore, the correct sequence is Option A (plug the USB lead to a running VLQ) followed by Option B (run software and select correct coms port).

    Which VLQ sample hole configurations may be used?

    • Use ASPIRE2 to determine

    • 2 X 6.5mm Sample holes

    • B & D

    • 4 X 4.5mm Sample holes total

    • None of the above

    Correct Answer
    A. B & D
    Explanation
    The correct answer is B & D. This means that the VLQ sample hole configurations that may be used are those with 2 X 6.5mm sample holes and those with 4 X 4.5mm sample holes.

    Capillary tubes may be used with VLQ:

    • If shorter than 2 meters

    • If concealed in wall cavity

    • VLQ does not support capillaries

    • If less than 300mm long

    Correct Answer
    A. If less than 300mm long
    Explanation
    The correct answer is "If less than 300mm long". This means that capillary tubes can be used with VLQ if they are shorter than 300mm in length. This suggests that there is a specific length requirement for the capillary tubes when using them with VLQ, and if they are shorter than 300mm, they can be used.

    VLQ airflow normalizing:

    • Can be done through QSC

    • A & D

    • Is not required

    • Can be done through the display panel

    Correct Answer
    A. A & D
    Explanation
    VLQ airflow normalizing can be done through QSC and the display panel. This means that there are two methods available to perform this task. It is not necessary to perform VLQ airflow normalizing, but if it needs to be done, it can be accomplished using either QSC or the display panel.

    What is quiescent current consumption?

    • 190mA

    • 4 Amps

    • 1.2 Amps

    • 170mA

    Correct Answer
    A. 170mA
    Explanation
    Quiescent current consumption refers to the amount of current that a device or circuit consumes when it is in a standby or idle state. In this case, the correct answer of 170mA indicates that the quiescent current consumption is 170 milliamperes. This means that when the device is not actively performing any tasks or functions, it still consumes 170mA of current.

    VLQ requires what voltage to operate?

    • 120 – 240 VAC

    • 18 - 30 VDC

    • Solar or Wind Power

    • 12 VDC

    Correct Answer
    A. 18 - 30 VDC
    Explanation
    VLQ requires a voltage range of 18 - 30 VDC to operate. This means that the VLQ device can be powered by a direct current (DC) voltage between 18 and 30 volts. This voltage range is necessary for the proper functioning of the VLQ device.

    A suitable Application for a VLQ is:

    • 100m² or less risk areas

    • 500m² risk area

    • 6 Sample point installation

    • 150m² risk areas

    Correct Answer
    A. 100m² or less risk areas
    Explanation
    A VLQ (Very Low Quantity) application is suitable for areas that have a risk of 100m² or less. This means that the VLQ system is designed to handle small quantities of hazardous materials, making it appropriate for smaller risk areas where the potential for accidents or incidents is limited. It may not be as effective or necessary for larger risk areas or areas with higher quantities of hazardous materials.

    How can Alarms be made non-latching?

    • Set dipswitch 7 ON

    • Set dipswitch 6 OFF

    • Set dipswitch 1 ON

    • Set dipswitch 8 OFF

    Correct Answer
    A. Set dipswitch 6 OFF
    Explanation
    Setting dipswitch 6 OFF can make alarms non-latching. This means that once the alarm is triggered, it will not stay activated indefinitely until manually reset. Instead, it will only sound for a certain period of time and then automatically turn off.

    Using Dipswitches 1 – 3 set Pre-Alarm to 0.5%/m

    • OFF, OFF, ON

    • ON, OFF, ON

    • ON, ON, ON

    • OFF, OFF, OFF

    Correct Answer
    A. OFF, OFF, ON
    Explanation
    The correct answer is "OFF, OFF, ON". This means that Dipswitch 1 is set to OFF, Dipswitch 2 is set to OFF, and Dipswitch 3 is set to ON. This configuration sets the Pre-Alarm to 0.5% per minute.
