Frequently Asked Questions

1. What is a duct carbon monoxide (CO) transmitter?
   The Ace Instruments Duct Carbon Monoxide Monitor (AI-CO-D) is a rugged, economical device designed to track CO levels within HVAC ducts. It provides simultaneous measurement and transmission of CO levels to a central controller or Building Management System (BMS) , housed in a durable duct-mounting ABS plastic enclosure.

2. Why is it important to monitor CO in HVAC ducts?
   ‍Carbon monoxide is a colorless, odorless, and highly toxic gas. Monitoring CO in ducts helps improve occupant comfort and the overall building environment. It is an essential component for Demand Control Ventilation (DCV) , ensuring that fresh air is automatically introduced when dangerous gas levels are detected in commercial buildings, cleanroom environments, and industrial facilities.

3. What sensing technology does the AI-CO-D use?
   To ensure high accuracy and long-term reliability, the AI-CO-D utilizes an electrochemical type sensor. For maximum safety and compliance, this sensing element meets strict global requirements, including UL2034, EN50291, and EN54-31 standards

4. What are the measuring range options for the AI-CO-D?
   The AI-CO-D is customizable to your facility's safety requirements, offering range options up to 500 ppm. Depending on your specific application, you can select from measuring ranges of 0-100 ppm, 0-250 ppm, or 0-500 ppm.

5. Can the AI-CO-D be used in retrofit applications?
   The AI-CO-D, serves as a part replacement for Greystone CMD5B Series (Duct Carbon Monoxide Detectors), Siemens Q-Series (specifically QPA/QPB Duct CO Sensors), Honeywell HSCM & E3Point Series (Carbon Monoxide Transmitters), Dwyer Series GSTA & GSTC (Carbon Monoxide Transmitters), Belimo 22CG Series (Duct Gas Sensors).
   
   
6. How fast is the response time of the AI-CO-D?
   The AI-CO-D has a T90 response time within 60 seconds.
   

7. How does the AI-CO-D connect to a Building Management System (BMS)?
   The instrument connects seamlessly to controllers using industry-standard analog outputs, which are field-selectable between 4-20mA and 0-10 VDC. For advanced digital networks, the AI-CO-D also features optional RS-485 Modbus communication.
   

8. Can the AI-CO-D control ventilation equipment directly?
   Yes, the instrument features an optional 1 No. relay output (CO/NO/NC). This allows for the optimal control of CO levels directly within HVAC ducts, meaning the sensor can trigger exhaust fans, open dampers, or sound local alarms even without relying solely on the central BMS.
