F-Guard UV-IR-HD User Manual

76-M-6010-02-02

1. Introduction

The

F-Guard-UV-IR-HD

flame detector provides 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. 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. The detector provides high-definition (HD) video

output of the monitored area with clear imaging of a fire event and of personnel at distances up to 100 ft

(30m) allowing rescuers to discover the exact situation before entering the hazardous area. It will

automatically record a video of a fire event (1 min pre-alarm/up to 3 mins post-alarm).

The integral HD quality video, with event recording, on top of the proven superior capabilities of UV-IR flame

detection together provide a very powerful safety tool to protect your personnel, plant and process. As

an option, the color HD camera can be replaced with a near IR camera if greater flame definition is needed.

This manual covers two UV/IR detector models:

F-Guard-UV-IR-HD

: 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-HD

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

micron range

Key Features

•

High immunity

: To false alarm

•

Ultra-fast detection mode

: Within 5 milliseconds for Hydrogen fireballs or explosions

•

Hydrogen and hydrocarbons flame detection

•

High sensitivity

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

•

HD video output

: With automatic HD video recording of fire events

•

Option: Improved speed of response:

(0.5s) for enclosed spare protection, like automotive

applications in compliance with NFPA 33 or printing presses and conveyors.

•

Data/Event logger

: Alarms, faults and other relevant events are logged to non-volatile memory

•

Ethernet communication

: In addition to the standard methods, such as 4-20mA and Modbus

•

Built-in-Test (BIT)

: Automatic and manual internal self-test of window cleanliness and the overall

operation of the detector (for both IR and UV channels)

•

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.
