  • Page 4: Introduction

    Fires can cause very great damage to the environment and to property. In addition, there is a high potential risk to humans. The primary goal of the LOX system is to prevent fire in a specific area or to drastically reduce the risk of fire. A fire that does start, despite of the precautions, will remain limited and will develop less quickly.
  • Page 5: Precautions And Safety Instructions For Nitrogen Generators

    Precautions and safety instructions for nitrogen generators General safety standards When working with the nitrogen generator of FX Prevent, there are some safety risks that have to be considered. The risks involve subjects such as dangerous voltage, high pressure and dangerous gas to inhale. This is addressed in this chapter. It is highly recommended that the safety risks are observed before work on the devices is commenced.
  • Page 6 For the precautions and safety instructions of miscellaneous components that are related to the nitrogen generator, please refer to the enclosed instructions of those components that are provided by the respected manufacturers. These can be found with the specific components upon delivery or are included within the technical file of system of which the nitrogen generator is part of.

    Door display at each entrance door except for automatic sluices. If the LOX oxygen reduction system is used to protect a refrigerated area where the temperature is below 0 °C, an alternative assembly is used. In this application, the following components are placed outside the protected areas: •...

    As soon as there is a temporary voltage drop, the compressor must be activated manually. The compressor switches off for safety reasons and may not be switched on automatically. The LOX system switches itself on again and reports a power failure in the log.
  • Page 10: Lox Opstelling

    Depending on the dimensions, the shape of the room and the objects present, nitrogen is injected at one or more locations. If several rooms are protected with one LOX installation, the distribution is regulated by means of valves. The supply of nitrogen is automatically controlled via the LOX control software and is not described separately in this manual. LOX controller The LOX controller is the nerve center of the installation.

    If a single sensor shows a large deviation, this may indicate an abnormal oxygen content or a defect. This is immediately indicated by an alarm message. The oxygen sensors are part of the LOX installation and are therefore not described separately in this manual. Operation takes place via the LOX controller.

    Operation takes place via the LOX controller. A second possibility is that the LOX system is connected to the fire alarm system or is part of a quick release system. In these cases, the details are given in the relevant manual.
  • Page 14: Ecd Display

    ECD Display The ECD Display is the main control device that the operator can use to work with the LOX system. It is included in the leading N2 Controller and is connected to the LOX Control (ECD) components. With the ECD display, the user can do several things, such as view the status of the LOX system, view active measurements, view settings and adjust settings with the buttons on the display.

    Status LED’s Below the ECD display there are 2 columns of LED lights which give the user direct information on the status of the LOX system. Which LED lights are featured at the ECD display and what their functions are is described in the following table.
  • Page 18: Assembly Instructions

    The LOX system is a combination of several machines. The joint purpose of the combination of machines is to condition the room that needs to be secured by means of nitrogen supplementation. To achieve the goal of oxygen reduction, it is necessary to assemble the system in the right way.
  • Page 19: Errors

    The LOX Controllers (ECD) are software-controlled devices. This means that in case of a defect, error or alarm, a message is generated to inform the user that something is wrong. If an error or alarm occurs, there are several ways in which the LOX system will inform the user.
