Agni Universal Air Smoke Sampling Duct Detector Enclosure
The Universal Air Smoke Sampling Duct Detector Enclosure is designed to detect smoke inside HVAC and ventilation ducts before it spreads throughout a building. The enclosure supports both conventional and addressable smoke detectors and ensures reliable smoke detection by continuously sampling airflow through specially designed inlet and outlet tubes. It features a transparent inspection cover, high-strength ABS enclosure, and supports airflow speeds from 0.2 m/s to 20 m/s, making it suitable for commercial HVAC fire detection systems.

Description
The Universal Air Smoke sampling Duct Detector Enclosure is designed to detect smoke inside HVAC and ventilation ducts before it spreads to other areas of a building. Installed directly on air ducts, the enclosure continuously samples airflow through specially designed inlet and outlet tubes to monitor smoke particles inside ventilation systems.
This early smoke detection mechanism prevents smoke generated from fire from circulating through air-conditioning ducts and reaching unaffected areas of a facility. The system supports both conventional and intelligent addressable smoke detectors, allowing flexible integration with most fire alarm systems.
The enclosure is constructed using high-strength ABS plastic and features a transparent front cover, enabling easy inspection of the installed smoke detector without opening the housing.
Designed from reliable performance in HVAC environment, the detector enclosure operates effectively at airflow speeds ranging from 0.2 m/s to 20 m/s, making it suitable for commercial buildings, hospitals, shopping malls, factories, and large infrastructure projects.
The device include a 250 mm sampling tube and standard with additional tube length available for wide ducts. These tubes incur proper airflow through the detector chamber for accurate smoke detection and enhance fire safety.
How it Works
How does the Universal Air Smoke Sampling Duct Detector Enclosure Work?
The Agni Adam Voice Alarm Series Plus Exit Point Navigator Sounder operates as an intelligent voice evacuation device within a fire alarm system. It not only produces a loud audible alarm but also delivers clear multilingual evacuation instructions to guide occupants safely.
Commonly Used
- Shopping Mall HVAC System
- Hospital Ventilation System
- Data Center Cooling System
- Commercial Office Building
- Industrial Factory Ventilation
Step-by-Step Air Smoke Sampling Duct Duct Detector Enclosure Working Principle?
01
Air is Sampled from the HVAC Duct
Sampling tubes installed across the air duct collect air from inside the ventilation system as it flows through the duct.
02
Air Passes Through the Detector Chamber
The sampled air travels through the enclosure and enters the smoke detector chamber installed inside the unit.
03
Smoke Particles Are Detected
If smoke particles are present in the airflow, the smoke detector identifies the particles and switches to alarm mode.
04
Alarm Signal is Sent to the Fire Alarm System
Once smoke is detected, the detector sends a signal to the fire alarm control panel connected to the building’s fire safety system.
06
Safety Systems Activate
The building safety system can trigger automatic actions such as: Activating fire alarms, Shutting down HVAC fans, Closing fire dampers, Initiating evacuation alerts.

Job to be Done
Primary Job
Detect smoke inside HVAC ventilation ducts at an early stage and trigger the fire alarm system to prevent smoke from spreading through the building’s air circulation system.
Safety Job
Protect building occupants and infrastructure by identifying smoke inside ventilation ducts early and preventing dangerous smoke circulation through HVAC systems.
Functional Jobs
Detects smoke within HVAC duct airflow and triggers the fire alarm system to stop ventilation and alert occupants before smoke spreads through the building.
FAQ
What is Universal Air Smoke Sampling Duct Detector Enclosure?
A Universal Air Smoke Sampling Duct Detector Enclosure is a device installed on HVAC ducts to detect smoke inside ventilation systems. It samples air flowing through the duct and triggers a fire alarm when smoke particles are detected.
How does a duct smoke detector enclosure work?
The enclosure uses inlet and outlet sampling tubes to draw air from the HVAC duct into the smoke detector chamber. When smoke particles are detected in the airflow, the connected smoke detector activates the fire alarm system.
Do I need a smoke detector inside an HVAC duct?
Yes, Smoke detectors inside HVAC ducts detect smoke moving through ventilation systems. This prevents smoke from spreading to other areas of the building through air circulation.
Is this enclosure compatible with any smoke detector?
Yes, The Universal Air Smoke Sampling Duct Detector Enclosure supports both conventional and addressable smoke detectors, making it compatible with most fire alarm systems used in commercial buildings.
Why is early smoke detection in ducts important?
Smoke can travel quickly through the ventilation system. Early detection helps stop smoke circulation and protects building occupants from smoke inhalation.
