Model FL4000H
2.0 Product Overview
2.1 General Description
The General Monitors’ FL4000H is a Multi-
Spectral Infrared (MSIR) Flame Detector
(Figure 6). The FL4000H employs state-of-
the-art infrared (IR) detectors and a
sophisticated
artificial neural network
(ANN)
based signal processing to produce a system
that is highly immune to false alarms caused
by lightning, sunlight reflection, arc-welding,
hot objects, and other sources of radiation. In
addition, the FL4000H can see through most
smoky type fires such as diesel, rubber, etc.
The FL4000H is certified as explosion proof
for use in hazardous locations (Section 8.3.2).
It can also be used for general-purpose, non-
hazardous applications.

2.2 Features and Benefits
High False Alarm Immunity
: Provides reliable flame detection performance by utilizing a
proprietary ANN processing algorithm to minimize false alarms. Please refer to Sec. 8.4 for more
details on the behavior of the instrument in the presence of false stimuli.
Wide Field of View (FOV)
: Encompasses a larger area of detection with uniform sensing and no
blind spots.
Modular Design
: Results in low maintenance and reduced total cost of ownership.
Compact Unitized Design
: Enhances ease of installation and maintenance.
Continuous Optical Path Monitoring (COPM)
: Regularly monitors the optical path to ensure the
window is not dirty.
0-20 mA Analog Output
: Transmits alarm and fault indication to a remote display, computer, or
other device such as an alarm, dispensing device, or master controller.
Dual Redundant Modbus RS-485 User Interface (Standard FL4000H Configuration)
:
Provides
the capability to operate the FL4000H remotely, using 2 redundant channels. This interface allows
the user to remotely change the alarm and warning relay settings, clear selected faults, clear error
counters, change baud rates, and change formats for serial communication lines.
HART Protocol
2
(Optional HART Configuration):
The HART equipped FL4000H supports the
HART communication protocol version 6. Using this protocol, users can transmit diagnostics,
settings, and other device status information that improves the efficiency of remote communication.
NOTE:
FL4000H HART should not be used with General Monitors TA402A and FL802
Controllers.
