Manning Systems Airscan IRF9 Quick Start Guide

Manning AirscanTM IRF9 SPECIFICATIONS

Refrigerant, Ammonia
and Carbon Dioxide Detector

General Specification

Use Infrared (diffusion) type sensor that works in conjunction with any Honeywell Analytics Manning readout or alarm unit.

This sensor platform can detect either Ammonia, Carbon Dioxide, or a number of refrigerant gases.

Sensor Specifications

Response Time T90 = 10 seconds

with full-scale calibration gas @ .75 litres/min. flow rate

Ranges R Gases: 0-500 ppm, 0-1,000 ppm, 0-3,000 ppm
CO

Sensor Viability Test SensorCheck, an internal microprocessor determines the sensor’s electrical viability every 24 hours. If the
viability test fails a 0.5 mA signal will indicate a fault. An internal light will show if a sensor is dried up or
disconnected.

Enclosure 16 gauge painted steel or stainless steel. NEMA 4, UL 508 listed, CSA certified for use with industrial control equipment.

Weight 4.4 lbs.
