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 FL3100 is an Ultraviolet/Infrared (UV/IR) Flame
Detector (Figure 2-A). It detects the Ultraviolet and 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.
The Model FL3101, is an Ultraviolet (UV) flame detector (Figure 2-B). It only
responds to UV and has been optimized for speed of response.
Both units may be used with the General Monitors TA40X Modules, FL802
controller, or with other equipment which accepts the 4 to 20mA output. They
may also be interfaced directly with alarm/suppression devices or with switched
input modules using integral relays.
NOTE - Model FL802 is not CE Marked and, therefore, cannot be supplied to the
EU.
