Autronica Gas Detection

In the demanding environments of the petrochemical oil and gas industry, fire and gas detection has to deliver optimal results at all times. Autronica gas detection  offers traditional detectors with 4-20 mA and/or relay output, but we have also taken the IR point gas detection a step further.

Product Introduction

A key feature of the HC300PL IR gas detector is the built-in PowerLoop system technology, enabling the detector to communicate with AutroSafe Integrated Fire and Gas (IFG) systems on a single pair of wires. This compatibility, called the PowerLoop technology, is a two-wire power and signalling bus connected in a ring topology and galvanically isolated from the rest of the system, saving cable cost and weight. Each detector has a built-in short-circuit isolator, hence no detectors will be lost because of a single break or short-circuit in the PowerLoop lines. All alarms and faults are signalled via the PowerLoop. The Fire and Gas Detection Systems supplier  does not require any local power supply.
