INTRODUCTION
The Model 20/20MI-32-S-F is a Triple IR spectrum flame detector designed to provide maximum fire protection. It uses innovative tech-
nology of advanced digital signal processing to analyze the dynamic characteristics of fire. Three sensitive IR channels process the
signals. Detection performance is controlled by a microprocessor and easily adapted to all environments, applications and requirements.
The result is a unique and superior flame detector, which provides excellent detection sensitivity with extreme immunity to false alarm.
Although there are more than one basic model of the 20/20MI Triple IR flame detector and each has numerous features, only the models
20/20MI-32-A-F* and 20/20MI-32-S-F features are applicable to vehicle fire protection using the CHECKFIRE SC-N detection module.
Only the 20/20MI-32-S-F features are addressed in this manual.
