Ultraviolet and infrared flame detection provides high immunity to false alarms
The FlameGard 5 UV/IR-E Flame Detector is
designed to detect unwanted fires and provide
alarm outputs directly from the detector while
maintaining false alarm immunity. It detects
fires by monitoring in both the ultraviolet and
infrared (UV & IR) spectral ranges making it
highly immune to false alarms caused by
lightning, arc welding, hot objects and other
sources of radiation.
The detector’s electronics are integral within
an explosionproof housing, allowing detector
information to be processed at the point of
detection. The electronics are fully separated
from the EExe wire compartment, offering pro -
tection during installation and service. The
model is available in a number of output
configurations:
 4–20 mA stepped output + single serial
communications port
Dual serial communications ports
Warning, alarm and fault relays
Alarm and fault relays with on-board EOL and
alarm resistor
4–20 mA stepped output only
The serial communication port(s) allows 128
units (247 using repeaters) to be linked up to
a host computer using the Modbus RTU
protocol. The communication registers provide
alarm status, fault and other information for
operation, trouble shooting or programming
the unit.
The COPM (Continuous Optical Path Monitor -
ing) self test feature checks the optical path
integrity (window cleanliness) and the de -
tector’s electronic circuitry once every minute.
