    The following apply to instruments that are to be used in compliance with the CSA certification: Radius BZ1 Area Monitor is CSA-certified according to the Canadian Electrical Code for use in Class I, Division 1 and Zone Classified Hazardous Locations within an ambient temperature range of T : -20 °C to +55 °C.

  • Page 12: Warnings And Cautionary Statements

    : -20 °C to +55 °C. This is applicable when the monitor is used in the diffusion or aspirated mode and has been calibrated to 50% LEL CH In addition to the certifications listed below, refer to the Industrial Scientific websites for the most up-to-date information about wireless product certifications.

    • Train instrument users. Placement Guidelines To develop a placement plan for each unique, in-field application of Radius BZ1 instruments, keep in mind all relevant gas, site, and LENS™ Wireless (Linked Equipment Network for Safety) factors, which include but are not limited to the following.

    Table 1.4. These recommendations are provided to help support worker safety and are based on field data, safe work procedures, industry best practices, and regulatory standards. Industrial Scientific is not responsible for determining a company’s safety practices or establishing its safety policies, which may be affected by the directives and recommendations of regulatory groups, environmental conditions, operating conditions, instrument use patterns and exposure to gas, and other factors.

  • Page 17: Biased Sensors

    • When the module is not installed in a Radius Base, its biased sensors will be powered by the module’s backup battery to help maintain sensor stability. When a biased sensor is in use and the Radius BZ1 emits a low battery warning or a low backup battery warning, complete the steps noted below.

  • Page 18: Remote Sampling

    The power requirements of biased sensors can exceed the setpoint for the low backup battery warning. When a sensor’s required power exceeds what the backup battery can supply, the Radius BZ1 will indicate a sensor error, so in some cases, the cause of sensor error for a biased sensor may need to be treated as a low backup battery warning as described above.

  • Page 19: Care And Storage

    • Industrial Scientific recommends the SafeCore Module be stored in the Radius Base; this will help support conservation of the module’s backup battery, a power source that maintains the module's clock and is needed when biased sensor are installed.

  • Page 21: Product Information

    The Radius BZ1 can be operated as a stand-alone gas-detection instrument for area monitoring. This is suitable for applications where the goal is use a Radius BZ1 in a manner that will alert nearby workers to gas hazards and provide optional, instructional messages for specific hazards.

  • Page 22: Key Features

    Key Features Modularity The Radius BZ1 Area Monitor consists of the SafeCore® Module and Radius Base. When installed in the Radius Base, the SafeCore Module, serves as the instrument's central processing unit. It houses the gas sensors, electronics, firmware, data log, settings, wireless radio, clock and clock battery, and the pump (aspirated instruments only).

  • Page 23: Lens Wireless

    • View instrument status summaries. Messaging Radius BZ1 instruments give the safety team a variety of options to provide instrument operators with customized on-screen messages**. This includes a custom start-up message, which displays during the power-on process. A unique instructional message, or "alarm action message", can be set for each of these gas events for each sensor: gas present (low alarm and high alarm), STEL, and TWA.

  • Page 93: Supplemental Information About Gases And Sensors

    Appendix A Supplemental Information about Gases and Sensors Cross Sensitivity and Toxic Gases A sensor is designed to detect for and measure the presence of a particular gas, the "target gas"; however, it may also respond to other gases. When this is the case, the sensor is said to have "cross-sensitivity" to another gas, which will interfere with the target-gas readings.
  • Page 94 For example, if the instrument reads 10% LEL in a pentane atmosphere, and was calibrated to methane, the actual percentage LEL is determined as follows: Locate the table cell where the sample gas (pentane) intersects with the calibration gas (methane). Multiply the cell's value (2.02) by the instrument's LEL reading (10%) to calculate the actual concentration of 20.2% LEL.
