F-Guard IR3 HD User Manual

1 Introduction

The F-Guard-IR3-HD (F-Guard-IR3-HD) will detect fires and explosions extremely

quickly allowing preventative action to be initiated rapidly to help minimize the

consequences!

•Detection within 40 milliseconds of fireballs or explosions

•Standard fire is detected within 1.5s from 100 ft. (30m), 4.1s from 230 ft. (70m) and

9.0s from 262 ft. (80m).

The detector provides fast response, high performance and reliable detection of all types of

hydrocarbon fires (visible and non-visible). The detector addresses slow-growing fires as

well as the fast eruption of fire using improved triple IR (IR3) technology. It operates in all

weather and light conditions with the highest immunity to false alarms.

In addition, the detector provides high-definition (HD) video output of the monitored area

with clear imaging of a fire event and personnel at distances up to 100 ft (30m). This allows

the rescue team to be aware of the exact situation before entering the hazardous area. The

detector automatically records a video of a fire event (1-minute pre- and up to 3 minutes

post-alarm initiation). These features, along with the built-in event logger, provide additional

means to study the cause and development of fire events.

As an option, the colour HD camera can be replaced with a near IR camera if the greater

flame definition is needed.

Key Features

•Extreme sensitivity - up to 260ft (80m) for a 1 ft2(0.1m2) N-heptane pan fire.

•1.5 second detection time - for 1 ft2(0.1m2) N-heptane pan fire at up to 100 ft. (30m) distance.

•Ultra-fast detection mode - detection within 40 milliseconds for fireballs or explosions.

•HD video output with Automatic HD video recording of fire events. Data/Event logger: Alarms,

faults and other relevant events are logged to non-volatile memory.

•Option: Improved false alarm immunity in high CO2 applications, like aircraft hangars or

helidecks.

•Option: Improved speed of response - (0.5s) for enclosed spare protection, like automotive

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

•Built-in-Test (BIT) - Automatic (and manual) self-test of window cleanliness and the overall

operation of the detector.

•Window heater to avoid condensation and icing.

•Tilt mounting bracket for accurate detector positioning.

Model Number Description

Model No is defined as follows:

F-Guard-IR3-HD - A SX X

Standard with RGB camera

Like model 1 with Near IR camera

Like model 1, but recommended for Hangar, Helideck,

Petroleum Loading Racks with RGB camera

Like model 3 with Near IR camera

Like model 1 but with a fast response mode that is designed

for, but not limited to, automotive spray paint applications

where compliance with 0.5s response (per NFPA 33) is

needed. With RGB camera

M25

¾” NPT

1.2.1 Enhanced performance options

•Option 3: Increased false alarm immunity in presence of hot CO2. Recommended for

Hangar, Helideck and Petroleum Loading Racks

•Option 5: Design for, but not limited to, automotive spray paint applications where

compliance with 0.5s response (per NFPA 33) is needed

Internal tests

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. Any detected fault is indicated as shown in Table 4 (in section 4.1).

During the “Dirty Window” fault the detection sensitivity is significantly reduced, while “Fault”

refers to critical faults which prevent flame detection.

Accessories

1.5.1 Mounting Bracket

The detector should be mounted using the

stainless-steel tilt mount part number 85-

6000-TMO-HD. This allows the detector to be

securely attached to a wall, pole or other

solid surface using appropriate fixings. See

sections2.5 and 2.6 for further details.

FIGURE 3-TILT MOUNT

1.5.2 Weather Cover

The weather cover P/N 85-6000-WC-SS-

protect the detector from extreme weather

conditions such

as heat, rain and snow

1.5.3 Pole mount

The pole mount enables the detectors tobe

installed with its tilt mount brackets. The pole

mount kit we supply is suitable for 2-inch or 3-

inch poles. Part number F-Guard-PMA-S23.

FIGURE 5-POLE MOUNT

1.5.4 Air shield

The air shield P/N F-Guard-ASD-S02 allows

the installation of flame detectors in harsh

weather conditions where they may be

exposed to dust, sand, and other particulate

matter. The connection point can be mounted

in the 3, 9 or 12 o’clock locations.
