Product Overview
There are 2 versions of the 40/40 Series UV/IR Flame Detectors:
•
Model 40/40L (and LB) provides a combination of UV and IR sensors, where
the IR sensor operates at a wavelength of 2.5
–
3.0µm, and can detect
hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as
metal and inorganic fires.
•
Model 40/40L4 (and L4B) is identical to the 40/40L, except that the IR sensor
works at a wavelength of 4.5µm and is only suitable for hydrocarbon-based
fires.
The Built in Test (BIT) feature is only included in models 40/40LB and 40/40L4B.
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 confi
guration 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).
Warning:
The detector is not field-repairable due to the meticulous alignment
and calibration of the sensors and the respective circuits. Do not
attempt to modify or repair the internal circuits or change their
settings, as this will impair the system’s performance and void the
SPECTREX product warranty.
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.

Approvals
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)
