2 INTRODUCTION

2.1 General Description

Thank you for purchasing our low prole cGas DetectorTransmitter. The cGas Detector is designed

for use in publicly occupied spaces:

• where integrated demand controlled ventilation (DCV) is used for air quality and energy

savings

• for continuous monitoring of refrigerants where high-eciency, high volume refrigerant

cooling and heating systems (VRF) are used to keep the indoor environment comfortable

• for other continuous monitoring of hazardous gases in publicly frequented areas
