Gas detection is crucial for maintaining safe and compliant environments in various commercial and industrial settings. Whether you’re working in a manufacturing facility, laboratory, or a commercial building, the ability to detect dangerous gases can be a life-saving measure. AGS Controls offers versatile gas detectors like the ACi and ACiS Detectors, which are ideal for duct-mounted applications, providing reliable monitoring of a wide range of gases such as natural gas, carbon monoxide, LPG, hydrogen, nitrogen dioxide, and carbon dioxide.

What Are Duct-Mounted Gas Detectors?

Duct-mounted gas detectors are installed within a building’s air ventilation and duct systems to monitor the air being circulated. These detectors ensure that hazardous gases are identified early, allowing building management systems (BMS) or building automation systems (BAS) to take preventive actions, such as activating alarms or shutting down HVAC systems, to mitigate risks.

Duct-mounted detectors are highly beneficial in applications where gas buildup may not be concentrated in a single location, but rather, distributed through a building's ventilation system.

Applications of ACi and ACiS Gas Detectors

The ACi and ACiS detectors from AGS Controls offer flexible installation options, including both duct mounting and wall mounting, making them suitable for various environments.

1. Commercial Buildings (Offices, Shopping Malls, Hotels)

In commercial settings, HVAC systems play a significant role in maintaining indoor air quality. Gas leaks in such environments can be distributed throughout the building via ventilation ducts. With the ability to detect gases like natural gas (methane) and carbon monoxide, the ACi and ACiS Detectors are an excellent choice for protecting the health and safety of building occupants.

• ACi Detector: This gas detector is equipped with a compact design, LED status display, and BMS/BAS communication capabilities, making it an ideal choice for seamless integration into a building's automation system.
• ACiS Detector: Featuring a traffic light indicator, the ACiS detector visually displays gas levels, giving immediate clarity to building operators about air quality. Its in-built audible alarm also ensures that quick action is taken in the event of a gas leak.

2. Industrial Facilities (Factories, Warehouses)

Factories and warehouses that handle materials like LPG (propane), hydrogen, and other combustible or toxic gases require advanced gas detection systems. Duct-mounted gas detectors help monitor large areas where gases may disperse through the facility's ventilation system. Installing an ACi or ACiS Detector in duct systems provides 24/7 monitoring, ensuring that potential gas leaks are detected before they become hazardous.

• Hydrogen Detection: Given hydrogen's increasing use in clean energy, these gas detectors are essential in preventing explosive hazards in hydrogen storage and production facilities.

3. Laboratories and Research Facilities

Research environments often involve the use of nitrogen dioxide (NO2), carbon dioxide (CO2), and hydrogen sulphide (H2S). These gases, if undetected, pose severe risks to researchers and equipment. Duct-mounted detectors are advantageous in ensuring air circulated through the lab is free from these harmful substances.

• Carbon Dioxide Monitoring: In laboratory environments, where CO2 is frequently used, duct-mounted detectors like the ACiS Detector help maintain safe levels of this gas, protecting against asphyxiation hazards.

4. Kitchens and Food Service Areas

Kitchens, especially in commercial settings, often utilize natural gas for cooking. Duct-mounted detectors ensure that any undetected gas leaks are quickly identified and mitigated, preventing dangerous buildup in confined spaces.

• Natural Gas Detection: The ACi Detector, with its plug-and-play installation, allows for quick setup and integration into kitchen duct systems, ensuring compliance with safety standards.

How Duct Mounting Works

Duct mounting a gas detector involves placing the sensor directly inside or adjacent to a ventilation duct, allowing it to monitor the airflow for traces of harmful gases. The detector is installed using a duct mount kit, which is an additional accessory designed to secure the device in place and ensure accurate readings.

Duct-mounted detectors are highly effective in facilities where gases might escape from localized points but become diluted and distributed throughout the air system. By monitoring the duct air, these detectors provide broader coverage than wall-mounted options in certain applications.

Key Features of AGS Controls’ ACi and ACiS Detectors

1. Multi-Gas Detection: Both the ACi and ACiS Detectors support a wide range of gases, making them versatile for different industry needs, including the detection of methane, LPG, carbon monoxide, hydrogen, carbon dioxide and more.
2. BMS/BAS Integration: These detectors can communicate with building automation systems, allowing facilities to monitor air quality centrally and automate emergency responses.
3. Compact and Modern Design: With a sleek design and easy installation, both detectors blend seamlessly into their environments, whether in ducts or on walls.
4. Visual and Audible Alerts: The ACiS Detector uses a traffic light display indicator for clear visual alerts, while both models feature in-built audible alarms to ensure swift action when gas levels rise. The ACi Detector uses an LED indicator.
5. Plug-and-Play Installation: Both the ACi and ACiS Detectors offer simple installation, reducing downtime and making it easier for facility managers to ensure safety.
