1.1 OVERVIEW
The Model 3600I is a flame detector that utilizes improved IR3 technology to provide
state-of-the-art fire protection. The 3600I uses patented digital signal processing to
analyze the spectral and dynamic characteristics of the measured infrared radiation, to
identify fire events with exceptional sensitivity and extreme immunity to false alarms.
All 3600 series detectors include a heated optical window for improved performance in
icing, snow and condensation conditions.
Detection performance can be easily adapted to all environments, applications and
requirements, by changing the detector’s configuration parameters. Adjusting these
parameters, as well and performing other maintenance and monitoring tasks, is
possible by means of RS485-based Modbus communication or HART communication
(in models with 0-20mA output).
The detector enclosure is ATEX certified EExd flameproof with an integral, segregated,
rear, EExe terminal compartment (avoiding exposure of the sensors and electronics to
surrounding environment). Hence the combined approval EExde IIB + H2 T5 (75°C) or
T4 (85°C).
The 3600 detectors are designed to operate as a stand-alone unit directly connected to
an alarm system or an automatic fire extinguishing system. The detector can also be a
part of a more complex system, where many detectors and other devices are integrated
through a common control unit.
