Gas
Two major driving forces behind gas sensor selection are Demand Control Ventilation Systems and concerns over air quality. ACI has been supplying Carbon Dioxide sensors for years and is well versed in their application and technical support. ACI also carries a comprehensive line of CO, NO2, Toxic, Combustible, & Refrigerant Sensors.
Carbon Dioxide Sensors
- Multiple sensor outputs (0-5VDC, 0-10VDC, & 4-20mA)
- Background Calibration
Toxic, Combustible, & Refrigerant Sensors
- Field configurable
- Addressable RS-485 digital communication
- Numerous enclosure types

Interface Devices
Interface Devices are primarily used to transfer, modify, condition and isolate signals between controllers and HVAC devices such as damper actuators, heating/cooling valves, fans, and chillers. DDC systems often require Interface Modules to link equipment from different manufacturers and technologies.
Interface Devices help Building Automation System managers address the need to improve energy efficiency, regardless of the software, firmware or hardware involved. They offer you greater flexibility in several areas and can potentially save time, money, and energy. More importantly, they can show your clients your ability to be a problem solver!
