1.1 Overview
The 40/40M Multi IR Flame Detector is specifically designed for detection of
hydrocarbon and hydrogen flames. It detects hydrocarbon-based fuel and
gas fires at long distances with the highest immunity to false alarms. The
40/40M can detect a gasoline pan fire at 215 ft/65m or a hydrogen flame at
100 ft/30m in less than 5 seconds.
All 40/40 series detectors include a heated optical window for improved
performance in ice, 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 as performing other
maintenance and monitoring tasks, is possible by means of RS-485-based
Modbus communication or HART communication (in models with 0
– 20mA
output).
The detector enclosure is ATEX certified Exd flameproof with an integral,
segregated, rear, Exe terminal compartment (avoiding exposure of the
sensors and electronics to the surrounding environment). Hence the
combined approval:
Ex II 2G D
Ex db eb op is IIC T4 Gb
Ex tb op is IIIC T96°C Db
(
–55°C ≤ Ta ≤ +75°C)
or
Ex II 2G D
Ex db eb op is IIC T4 Gb
Ex tb op is IIIC T106°C Db
(
–55°C ≤ Ta ≤ +85°C)
The SharpEye 40/40 detector is 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.
