Agni Veiga Series Intelligent Addressable Analog Photothermal Detector (Multi-Criteria)
The Agni Intelligent Addressable Analog Photothermal Detector combines advanced smoke and heat sensing with intelligent algorithms to deliver early fire detection while minimizing false alarms, making it ideal for critical and complex environments.Â
Description
The Agni Veiga Series Intelligent Analog Photothermal Detector is a multi-criteria point detection device designed to provide reliable and early fire warnings by continuously monitoring both airborne smoke and temperature variations within the protected area.Â
This detector integrates photoelectric smoke sensing with thermal detection (fixed temperature and rate-of-rise), allowing it to respond quickly to a wide range of fire conditions while maintaining excellent immunity to false alarms. Intelligent algorithms analyze data from both sensing elements to ensure genuine alarm activation without compromising safety.Â
Built with a Dust Restrictor Chamber (DRC), the detector offers enhanced protection against airborne contaminants, improving long-term stability and performance. The low-profile design blends seamlessly into modern interiors, while high-visibility LEDs provide a full 360-degree status indication.Â
The detector communicates via AGNI’s fully digital intelligent communication protocol and supports auto-addressing on compatible fire alarm control panels. It is fully compliant with EN54 standards and designed in accordance with IS 2189 installation practices, making it suitable for commercial, industrial, and institutional fire alarm systems.
Job to be Done
Primary Job

How does the Agni Veiga Sounder / Horn Cum Strobbe Work?
1. Continuous Air & Temperature Sampling
The detector continuously monitors the surrounding environment by sampling airborne particles and ambient temperature within its sensing chamber.
2. Smoke Detection via Photoelectric Sensor
When smoke enters the chamber, the photoelectric sensor detects light scattering caused by smoke particles, indicating the presence of combustion products.
3. Heat Detection & Temperature Analysis
At the same time, the thermal sensor monitors fixed temperature levels and rate-of-rise changes to identify abnormal heat conditions.
4. Intelligent Multi-Criteria Evaluation
Data from both smoke and heat sensors is analyzed using intelligent algorithms to determine whether the combined pattern represents a real fire event.
5. Alarm Confirmation & Visual Indication
Once a genuine fire condition is confirmed, the detector activates its alarm state and provides a clear 360-degree LED visual indication.
6. Digital Alarm Communication to Panel
The detector transmits a digital alarm signal with its unique address to the fire alarm control panel, enabling precise location identification and rapid emergency response.
Product in One LineÂ
I need a reliable multi-criteria detector that senses smoke and heat accurately, reduces false alarms, and triggers timely evacuation and response during real fire events.Â
