  • Page 6: General Description

    VDC (DC Voltage) SENSALERT IR The SensAlert IR Transmitter is designed to be used with the SensAlert IR Sensor. The SensAlert IR is a microprocessor based intelligent transmitter continuously monitoring information from the gas sensor. The LCD of the SensAlert IR displays the gas concentration and sensor status. The SensAlert IR has one (1) “Alarm”...

  • Page 7: Operation

    The first step in the installation process is to establish a mounting location for the SensAlert IR Transmitter and Sensor. Select a sensor location that is typical of the atmosphere to be monitored or close to the anticipated source of a dangerous gas.
  • Page 8 Wire insulation should be temperature rated for greater than or equal to 70°C. There are 2 earth screws on the SensAlert IR Transmitter. One is on the outside of the enclosure and the other is located on the inside of the enclosure. Both are marked with earth ground symbols and green screws.

  • Page 9: Current Output

    0 for status code information If a fault is detected, the SensAlert IR Transmitter will display a fault notification on the LCD display giving the error code in decimal. Refer to section 10 for more information on the error codes.

  • Page 10: Optional Features

    5.2. Data Card Option The Data Card Option of the SensAlert IR Transmitter uses a MMC card to log different events to help track and changes or sensor behavior. See below for events that get logged: Gas Change Events- When a gas level rises or falls according to a pre-determined delta (change) threshold, a gas record is entered into the log by the SensAlert IR Transmitter, containing the timestamp and gas level at the time of the event.
