Duct Mount  

The duct mount (P/N 777670) is suitable for use with the SharpEye 40/40 Series 
Optical Flame Detectors 40/40L, LB, L4 & L4B, for both the aluminum and st.st. 
enclosure.  

The duct mount allows flame detection in areas where high temperatures exist or 
where the detector cannot be installed inside the area. It comprises a special duct 
mount arrangement with a specific optical window to allow installation in high 
temperature duct applications.  

The duct mount limits the cone of vision of the installed detector to 65° 
horizontal and 65° vertical. 

The temperature allowed for the duct mount to be installed is:  

–

55°C to +200°C / 

–

67°F to +392°F.
