F-Guard UV-IR User Manual

Doc. No. F110V0020.06

Introduction

The

F-Guard-UV-IR

flame detector provides an ultra-fast response, high performance and reliable detection

of a large variety of fires including hydrocarbon fires (visible and non-visible), as well as hydrogen fires (F-

Guard-UV-IR only).

The detector is certified for use in hazardous area locations; it may also be used in other areas not classified

as hazardous. The two cable/conduit entries on either side of the lower part of the detector housing are for

connecting power and outputs to associated signalling equipment.

The detector addresses slow-growing fires as well as fast eruptions of fire using improved UV-IR technology.

The detector operates in all weather and light conditions. It will automatically record a fire event (1 min

pre/post alarm) using the internal data logger.

During normal operation, the flame detector performs self-tests of its optics, electronics and software. These

include a periodic BIT (Built-In-Test) in which the sensors and window cleanliness are tested.

This manual covers two UV/IR detector models:



F-Guard-UV-IR:

Hydrogen and hydrocarbons flame detection. UV radiation 0.18-0.26 micron range.

Spectrum response of IR radiation in the 2.5 - 3.5 micron range.



F-Guard-UV-IR-F:

Hydrocarbon flame detection. Spectrum response of IR radiation in the 4.0-5.0 micron

range.

1.1

Key Features

•

High immunity

: To false alarm

•

Ultra-fast detection mode:

Within 5 milliseconds for Hydrogen fireballs or explosions

•

Extreme sensitivity

: Up to 100 ft. (30m) for a 1ft2 (0.1m2) n-heptane pan fire

•

Built-in-Test (BIT)

- Automatic and manual self-test of window cleanliness and the overall operation

of the detector.

•

Improved speed of response option

- (0.5s) for automotive applications in compliance with NFPA 33

•

Window heater

to avoid condensation and icing.

•

Tilt mounting bracket -

for accurate detector positioning.

•

UV and IR warning levels - 0-20mA

- current output warning when elevated UV or IR radiation is

detected.
