Description
The Omniguard® 660 and 860 Series Flame Detectors are optically
based, self-contained, microprocessor controlled, ultraviolet/infrared
(UV/IR) and high-speed ultraviolet (UV) flame detectors . The 860 Flame
Detector utilizes the patented Fire Event Analysis (FEA)™ discrimination
technology . These Flame Detectors are compatible with most alarm
panels without the need for a controller . All electronics are housed
within a copper-free aluminum, high temperature, TGIC-Polyester
coated enclosure with a 3/4-14NPT or M20-1 .5 conduit entry .
A stainless steel enclosure is also available .
The 660 and 860 Series Flame Detectors are suitable for use in Class
I, Division 1, Groups B, C and D (explosion-proof) areas and Class II,
Division 1, Groups E, F, and G (dust-ignition-proof) areas or

.T5 or T4 for gas,
Ex tb IIIC T100°C or T135°C Db for dust .
The housings are Type 4X or lP66, dust-tight and watertight . The
detectors are approved for both indoor and outdoor installations .
