Agni Veiga Series Intelligent Addressable Thermal Fixed Temperature Heat Detector
Intelligent addressable thermal detector combining rate-of-rise and fixed temperature detection for early and reliable fire alerts in challenging environments.Â
Part Number: VEIGA-IND-HT | Category: Intelligent Analog Addressable Detector
Description
The AGNI Thermal Rate of Rise Cum Fixed Temperature Detector is a precision-engineered intelligent heat detector designed to provide early fire warning by continuously monitoring temperature variations.Â
By combining rate-of-rise detection with a fixed temperature threshold, these detectors are not suitable. It communicates digitally with compatible AGNI fire alarm control panels and supports auto addressing for easy system configuration.
Its low-profile design, 360-degree LED visibility, programmable alarm thresholds, and built-in magnet test facility make it ideal for commercial, industrial, and institutional fire alarm installations requiring accuracy, durability, and compliance. Â
Job to be Done
Primary Job
Help building owners and safety teams detect fire caused by abnormal heat rise or overheating and trigger an early, reliable alarm in environments where smoke detectors are not suitable.
Safety Job
Prevent fire-related injuries and property damage by reliably detecting abnormal heat rise or overheating early and activating timely fire alarms for safe evacuation and rapid response.
Functional Jobs
Detect rapid temperature increases caused by electrical faults or sudden combustion, Detect slow-developing fires when temperature reaches a fixed threshold, Provide precise addressable fire location to the control panel.

How does the Agni Veiga Thermal Detector Operate?
1. Continuous Temperature Sensing
The detector continuously monitors the surrounding air temperature using its built-in thermal sensing element.
2. Temperature Pattern Analysis
It analyzes both the rate of temperature rise and the absolute temperature value in real time.
3. Rate-of-Rise Detection
If the temperature increases rapidly at 7°C–10°C per minute, the detector identifies a fire condition and prepares to trigger an alarm.
4. Fixed Temperature Detection
If the temperature rises slowly and reaches approximately 57°C, the detector activates the alarm based on the fixed temperature threshold.
5. Alarm Signalling & Visual Indication
Once an alarm condition is confirmed, the detector sends its addressed digital signal to the control panel and activates 360° LED indication.
6. System Activation & Reset
The fire alarm control panel triggers alarms and safety responses. After the event is cleared, the detector resets and resumes normal monitoring.
Product in One LineÂ
Detect dangerous heat buildup early and trigger a reliable fire alarm in environments where smoke detection is not effective.
