Agni Veiga Series Intelligent Addressable Optical Photoelectric Smoke Detector
The Agni IND-OP is an intelligent addressable optical smoke detector designed for early fire detection. Using photoelectric light-scattering technology, it reliably detects slow-smouldering fires while offering high immunity to dust and false alarms.Â
Description
The Agni Veiga Series IND-OP Optical / Photoelectric Smoke Detector is a high-performance point smoke detection device engineered for intelligent addressable fire alarm systems. It continuously monitors air conditions within the protected area and provides an early warning of fire by detecting smoke particles using advanced optical sensing technology.Â
The detector operates with an infrared LED and photodiode housed inside a specially designed optical chamber. When smoke enters the chamber, light is scattered onto the sensor, triggering an alarm signal. The advanced smoke inlet and optical chamber design offer strong resistance to dust ingress, significantly reducing false alarms while maintaining high detection accuracy.Â
Equipped with Dust Restrict Chamber (DRC) technology, the detector provides enhanced immunity against airborne contaminants, making it suitable for offices, commercial buildings, and large installations. The low-profile, aesthetically pleasing design blends seamlessly into modern interiors.Â
The IND-OP detector supports intelligent digital communication, auto-addressing on compatible fire control panels, and programmable alarm thresholds. It is fully compatible with AGNI’s digital communication protocol and fire alarm control e quipment, ensuring reliable system integration and performance.
Job to be Done
Primary Job
When designing or upgrading a fire alarm system, I need a detector that can identify real fire conditions early, so occupants can evacuate safely and emergency response can begin without delay.
Safety Job
it performs the critical safety job of detecting smoke at an early stage and alerting the fire alarm system to protect life and property from fire hazards.
Functional Jobs
Feel confident that the building is protected at all times, Trust the system to activate only during genuine fire events, Reduce stress related to unnecessary evacuations or system faults.
How it Works
How does the Agni Veiga Optical Photoelectric Smoke Detector Work?
The Agni Veiga Optical / Photoelectric Smoke Detector works by using an infrared light source and sensor inside an optical chamber. When smoke enters the chamber, it scatters the light onto the sensor, triggering an alarm signal that is digitally sent to the fire alarm control panel, ensuring fast and accurate fire detection while minimizing false alarms through its dust-resistant chamber design . Â

How does the Agni Veiga Photoelectric Smoke Detector Works ?
1. Air Sampling
The detector continuously allows surrounding air to enter its optical chamber for constant monitoring.
2. Infrared Light Emission
An internal infrared LED emits light inside the chamber under normal, smoke-free conditions.
3. Smoke Entry
When a fire begins, smoke particles enter the chamber through specially designed smoke inlets.
4. Light Scattering Detection
Smoke particles scatter the infrared light onto the photodiode sensor, creating a detection signal.
5. Alarm Decision & Communication
The intelligent circuitry confirms the alarm condition and digitally sends the signal to the fire alarm control panel with the detector’s address.
6. System Alert & Response
The control panel activates visual and audible alerts, enabling quick evacuation and fire response actions.
Product in One LineÂ
To detect smoke early and instantly notify the fire alarm system, enabling timely evacuation and protection of life and property.
