  • Page 10: Introduction

    1 Introduction This manual provides specific information concerning the installation, operation, calibration, and maintenance of the SensAlarm Plus Universal Gas Monitoring System. SensAlarm Plus is capable of detecting the presence of potentially hazardous concentrations of Combustible vapors and gases, Toxic gases and Oxygen deficiency.

  • Page 11: Standard Features

    1.2.4 Transportable Calibration SensAlert Plus sensors have transportable calibration capabilities. Sensors may be calibrated in the shop or at Sensidyne and then installed in the field without any special tools or adjustments. When a new sensor is installed in the unit, the Monitor automatically adjusts to recognize the new gas type and range and adjusts system function accordingly.

  • Page 12: Factory Installed Options

    The sensor is mounted in a sensor interface assembly on the bottom of SensAlarm Plus. It can, however, be located up to 100 feet away. In this manner, the detection of heavier or lighter than air gases and the use of special fixtures such as sample draw or duct mounting can be easily done.
