1.0 Introduction
1.1 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 FL3112 is a Digital Frequency Infrared (DFIR) Flame
Detector. The Model FL3112 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 FL3112 can see through most
smoky type fires such as diesel, rubber, etc.
The Model FL3112 features include:
•
Compact unitized design.
•
Continuous optical path monitoring.
•
Wide field of view.
•
High false alarm immunity.
•
0-20mA, Relays, Field Loop and Modbus RTU RS-485 serial communications output
versions.
