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.
