• The gas detection and alarm system is a safety unit, not an analyzer or densitometer which performs
quantitative/qualitative analysis/measurement for gases. You must understand the features of the
indicator/alarm unit before using it, so that you can use it properly.
• The indicator/alarm unit displays a gas concentration on the character LCD (digital and bar meter display
<three colors of green, yellow, and red>) according to a signal from the detector head. Gas
concentrations are displayed in different colors according to danger levels, i.e., in green if neither of the
alarm setpoints is exceeded, in orange if the first alarm setpoint is exceeded, and in red if the second
alarm setpoint is exceeded.
• The indicator/alarm unit has two-step gas alarm contact and fault alarm contact.
• The indicator/alarm unit outputs gas concentration in 4 - 20 mA or digital data (RS-485: option).
