Overview
What it is and how it fits the system.
The Gent 803271.EX is a rate-of-rise heat detector listed as an intrinsically safe detector in the S4 mains powered interface unit order and product reference. It is specified for intrinsically safe detection circuits served by that interface unit.
Technical overview
The 803271.EX is an Intrinsically Safe Gent rate-of-rise heat detector designed for use with the S4 mains powered interface unit. It operates across an 8 V DC to 42 V DC range and is certified to EN 54-5A1R : 2000 / A1 : 2002 for heat detection performance. The device features a red flashing LED alarm indicator and is constructed from white ABS housing with an IP 43 rating when installed with the base and optional gasket.
It functions within ambient temperatures of -20 °C to +50 °C and tolerates up to 95% non-condensing relative humidity. Storage conditions extend from -25 °C to +75 °C. The detector carries VdS approval G 204059, CE certification 0786 - CPD - 20103, and Ex-protection classification Ex ib IIC T4 for use in intrinsically safe circuits. Physical dimensions with base are Ø 117 mm and height 62 mm, with a weight of approximately 110 g.
Compatibility requires the detector base (SKU 805590) and a Z-System Zener barrier (SKU 764744) for safe operation in ATEX II 2G environments. It is commonly deployed alongside other intrinsically safe devices in the S4 system, such as the 803371.EX optical smoke detector and related heat-sensing variants. Wiring details are specified in the installation manual.
