    3.2 Mounting the Enclosure Install the detector to a wall or bracket using the predrilled mounting flanges with I.D. 0.25 on 5 inch centers (Figure 1). If conduit is rigid and able to support the weight of the universal detector, the mounting bolts may be omitted. After you have determined the appropriate location for your gas detector, it is important to securely mount the gas detector using the predrilled mounting flanges on the enclosure.

  • Page 19: Chapter 5 Calibration Procedure

     Periodic bump tests are recommended if detector has potentially been exposed to incompatible gases to ensure correct operation  Follow these calibration guidelines to ensure proper operation of your RC Systems, Inc. gas detector:  Calibration accuracy is only as good as the calibration gas accuracy. RC Systems recommends calibration gases with National Institute of Standards and Technology (NIST) traceable accuracy to increase the validity of the calibration.

  • Page 20: Figure 9 Calibration Diagram

    Figure 11 Calibration Diagram Prior to beginning your calibration make sure you have the following items: 1. A cylinder of calibration gas with concentration equal to the SPAN GAS VALUE setting (RC Systems typically recommends choosing a value at 50% of full scale.) 2.

  • Page 21: Routine Calibration Procedure

    5.2 Routine Calibration Procedure Use the following step-by-step procedure to perform Zero and Span calibrations (Figure 1-2 may be used for reference to the Menus.): Note: The first three steps must be performed before the timer in the bottom right corner expires, 15 seconds, otherwise the SenSmart 6000 will exit back to the Data Display Screen.

  • Page 22: Bump Test Procedure

    5.3 Bump Test Procedure Note: A bump test, when performed correctly, is meant to check both sensor and alarm functionality. This results in expected alarms, and proper precautions should be taken. Also known as a functionality test, a bump test is not meant to test the accuracy of the detector, and no calibration settings are changed during the test.

  • Page 23: Chapter 6 Maintenance Procedure

    RC Systems recommends performing calibrations at regular intervals to ensure proper functionality of the Universal Gas Detector. During routine calibration, RC Systems recommends a visual inspection of sensor head, enclosure and conduit entries to check for cleanliness and physical integrity. Cleaning the detector is recommended when necessary, but be aware that some cleaning compounds may be detected by an operational detector depending on the sensor type.

    Appendix 5 Antenna Selection Antenna Transmission Range The distance radio signals can travel is dependent upon several factors including antenna design, transmitter power and free-space losses. In order for a wireless link to work, the available system operating margin (TX power - RX Sensitivity + Antenna gains) must exceed the free-space loss and all other losses in the system.

  • Page 37: Yagi Antennas

    Yagi Antennas Yagi antennas are directional along the central beam of the antenna. The folded element is towards the back and the antenna should be pointed in the direction of the transmission. Yagis should also be mounted with at least 1 to 2 wavelengths of clearance from other objects. The polarity of the antenna is the same as the direction of the orthogonal elements.

  • Page 39: Connections To Other Equipment

    Connections to other Equipment Surges can enter the wireless unit from connected devices, via I/O, serial or Ethernet connections. Other data devices connected to the wireless unit should be well grounded to the same ground point as the wireless unit. Special care needs to be taken where the connected data device is remote from the wireless unit requiring a long data cable.
