2.0 Introduction
2.1 General
Description
Fire is a phenomenon of combustion. Combustion is the continuous chemical
reaction of a reducing agent (fuel) and an oxidizing agent (oxygen, etc.) with the
evolution of thermal energy (heat). Fire is usually manifested in heat (IR), smoke,
light (visible), and flame (UV). Flame is the gaseous region of a fire where
vigorous combustion chain reactions take place. These reactions emit radiation
covering the Infrared, Ultraviolet and the Visible Spectral Regions.
The General Monitors Model FL3102 is a Dual Frequency Infrared (DFIR) Flame
Detector (Figure 14). The Model FL3102 detects the Infrared spectral regions of
flame to produce a system, which is highly immune to false alarms caused by
lightning, arc-welding, hot objects, and other sources of radiation. In addition, the
FL3102 can see through most smoky type fires such as diesel, rubber, etc.
The Model FL3102 has features that include:
•
Compact unitized design.
•
Continuous optical path monitoring.
•
0-20mA, alarm relays and MODBUS RTU-485 standard.
•
Wide field of view.
•
High false alarm immunity.
