CO (Carbon Monoxide), NO 2 (Nitrogen Dioxide), CH 4 (Methane), C 3 H 8 (Propane), H 2 (Hydrogen), O 2 (Oxygen), NH 3 (Ammonia), H 2 S (Hydrogen Sulfide), Cl 2 (Chlorine)

Features • High-accuracy Electrochemical Cell sensor for toxic gases and Catalytic (Pellistor) for flammables • 3 or 4-stage SPDT relay outputs with LED status indicators • NEMA 3 Robust Enclosure • Microprocessor-based control. • 10-Step Bar-Graph Display of gas levels • Programmable time delays to avoid nuisance alarms • Optional 4-20mA, 0-1V DC, 0-5V DC or 0-10V DC analog output • Optional remote sensor

Applications Energy savings through the intermittent operation of ventilation equipment in enclosed areas • Commercial or industrial locations where a sudden build-up of toxic and/or flammable gases may occur • Car Parking and Bus Maintenance Garages, Tunnels, Warehouses, Factories Food Processing and Bottling Plants, Wastewater Treat - ment Plants, Steel Mills, Cryogenic laboratories and Incineration Rooms • Stand-alone with relay outputs or analog outputs for direct connection to the existing Building Management System (BMS) or DDCS

T he Acme UniSet, with its microprocessor-based system, features a high quali - ty stand-alone controller providing all the necessary hardware for the continu - ous monitoring of a variety of toxic and combustible gases. This unit is prima - rily geared towards providing alarm activated relays for simple applications such as small parking garages
