INTRODUCTION

INTRODUCTION

The S200+ range of triple IR flame detectors comprises five flame detector variants. The detectors share the same flame detection circuitry, optics and main mechanical housing. Each variant is available as an Intrinsically Safe (i) or Flameproof (f) version except the S261+ which is available only in the Flameproof version. The five variants are:
VARIANT
Conventional 2-Wire Interface
4-20mA Current Loop Interface
Analogue Addressable Loop Interface
Relay Interface
MX Digital Interface

The S200+ Advanced Flame Detector offers a major improvement in both flame detection capability and immunity to blackbody radiation. The S200+ is available in intrinsically safe and flameproof models except for the
