F-Guard IR3 H2 HD User Manual

Model Number Description 

Model No are defined as follows

F-Guard-IR3-H2-HD - A     S    X    X

Standard with RGB Camera 

Like model 1 with Near IR Camera 

Design for, but not limited to, automotive spray paint applications 

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

with RGB Camera.  Generally used for enclosed spare protection. 

M25 

¾” NPT 

1.2.1

 

        

Enhanced performance options 

Option 5: Design for, but not limited to, automotive spray paint applications where compliance with 0.5 s 

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 “Dirty Window” fault the detection sensitivity is 

significantly reduced, while “Fault” refers to critical faults which totally prevent flame detection.
