Gent Intrinsically Safe Dual Angle Optical Heat Detector - Please use Base 805590.

The galvanic isolator, part number 17740-30, must be positioned as near as it can be to the Ex zone being monitored (Zone 1), preferably inside a Vigilon Mains powered Interface housing, either S4-34440-02 or S4-34440-12. Its specification covers EN 54-7: 2006 / -5 B: 2000 / A1: 2002 and CEA 4021, with VdS approval G 204061 and CE certificate 0786 - CPD - 20105/20106.

803374.EX is an O2H-multisensor detector serving Intrinsically Safe Areas Detection within the Gent by Honeywell IS range. The Ex protection code is Ex ib IIC T4, and ATEX category II 2G applies with the safety barrier, Part No. 764744, while the examination certificate number is TÜV 09 ATEX 554910.

Its standard specification is EN 54-7: 2006 / -5 B: 2000 / A1: 2002, CEA 4021, with VdS approval G 204061 and CE certificate 0786 - CPD - 20105/20106. Type of sensor is Smoke, covering max. 110 m² over a mounting height reaching max. 12 m. Quantity of detectors is limited to a maximum of 8 per zone.

Quiescent consumption reads 60 μ A @ 19 V DC, with 8 V DC to 42 V DC as the working supply. Entity limits read 21 V DC input voltage, 252 mA input current, 10 mA output current and 1 nF internal capacity. Ambient temperature for the multisensor is -20 °C to +65 °C, where the ATEX range figure is - 20 °C to + 70 °C.

Storage temperature runs from -25 °C to +75 °C, with humidity at ≤ 95% relative, non-condensing, and air velocity across 0 to 5.000 ft/min. The white ABS body, similar to RAL 9010, has a mass of approx. 110 g and an outline with base of Ø 117 mm, H = 62 mm, with IP 43 following from a base plus the optional base gasket.
