Description

The Agni Veiga Series Intelligent Addressable Photothermal Multi Detector (IND-OH) is a multi-criteria point fire detection device that combines an optical smoke detection chamber with a thermal sensing element. An onboard microprocessor processes the smoke and heat information using sophisticated algorithms to provide fast and accurate fire detection. Unlike a detector that responds to a single sensing parameter, the IND-OH evaluates optical smoke and thermal data together. This multi-criteria approach is designed to provide a faster response to genuine fire conditions while reducing the risk of unwanted alarms caused by environmental conditions. The detector is designed for mission-critical commercial and institutional environments where accurate and dependable fire detection is important. It can be used across different application environments, from clean office areas to electrically dense equipment rooms. The detector incorporates a Dust Restrictor Chamber (DRC) to help resist contamination from airborne dust and particulates over its service life. Its low-profile housing and 360° status LEDs provide a discreet appearance while allowing clear visual identification during inspection and fault checks. The Veiga IND-OH communicates using Agni's fully digital intelligent protocol and supports auto-addressing on compatible fire alarm control panels, helping reduce commissioning time for large addressable loops. ________________________________________ Key Features: • Intelligent addressable photothermal multi-criteria detector • Model: IND-OH • Combines optical smoke and thermal detection • Onboard microprocessor with advanced detection algorithms • Evaluates smoke and heat data together • Designed for fast and accurate fire detection • Helps reduce unwanted environmental alarms • Dust Restrictor Chamber (DRC) technology • Low-profile housing • 360° status LED visibility • Agni fully digital intelligent communication protocol • Supports auto-addressing on compatible fire alarm control panels • Designed for large addressable fire alarm loops • Suitable for commercial and institutional applications ________________________________________ How It Works: 1.
