1.1 Overview
The 40/40R Single IR Flame Detector detects hydrocarbon-based fuel and
gas fires using advanced flame tools.
All 40/40 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 SharpEye 40/40 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.
