Product Overview
There are 2 versions of the 40/40 Series UV Flame Detectors: Model 40/40U and
model 40/40UB, which also includes a Built-in-Test (BIT) feature.
The 40/40UV Flame Detectors detect hydrocarbon-based fuels and gas fires,
invisible hydrogen flames and fires from hydride, ammonia, saline, and other
organic fires.
Note:
This type of detector should not be exposed to a UV radiation source,
such as welding, sparks, or an electronic arc, as it will result in a false
alarm.
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).
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)
