A Bengaluru IT park manager was stunned when his facility received a show-cause notice despite having a functional fire alarm system and passing three consecutive inspections. The issue? While the building had conventional fire alarms, the fire department’s new interpretation of NBC 2016 “best practices” and anticipation of NBC 2025’s mandatory addressable system requirements meant the facility was falling behind evolving standards.
If you’re responsible for fire safety in an Indian building, this scenario should concern you. Fire detection technology is evolving rapidly, and NBC 2025 draft provisions make it clear: addressable fire alarm systems aren’t just “nice to have” anymore—they’re becoming mandatory for buildings above 15 meters.
India reported over 11,000 fire-related deaths in 2022 according to NCRB data. Many of these incidents occurred in buildings with fire safety certificates and functioning fire alarm systems. The problem? Traditional conventional fire alarms often can’t provide the precise location information that emergency responders need to act quickly.
This is where addressable fire alarm systems—and the emerging AIoT (Artificial Intelligence + Internet of Things) integration—change everything.
The NBC 2025 draft provisions released in March 2025 (Reference: CED 46(26992) WC) introduce specific technology requirements that represent a fundamental shift in Indian fire safety standards:
Modern AIoT fire safety systems go far beyond traditional smoke detectors. Advanced multi-sensor devices combine smoke, heat, carbon monoxide, and air quality sensors with AI algorithms that can distinguish between actual fire threats and false alarms. These systems analyze environmental patterns, occupancy data, and historical incident information to provide early warnings with unprecedented accuracy.
For instance, AI-powered video analytics can detect the visual signatures of smoke or fire in real-time, while machine learning algorithms process data from hundreds of sensors simultaneously to identify fire patterns that might be missed by individual devices. Companies like NFire are pioneering these advanced AIoT fire safety solutions, developing systems that combine multiple detection technologies with sophisticated AI algorithms to provide unprecedented accuracy in fire detection and response. This multi-layered approach dramatically reduces false alarms while improving response times.
AIoT systems are revolutionizing emergency response through intelligent evacuation management. During an emergency, these systems can:
Addressable Fire Detection Systems Mandatory
IoT-Enabled Fire Alarms Compulsory
Smart Evacuation Systems

If you’re still using conventional fire alarm systems (zone-based detection), you’re facing:
How they work:
Problems in Indian buildings:
Real impact:
In a 2023 Mumbai high-rise fire, responders lost 8 critical minutes searching a large zone before locating the actual fire source. The conventional system indicated “5th floor” but couldn’t specify which apartment or room.
How they work:
Advantages:
Real impact: In a 2024 Pune IT park, an addressable system identified “Server Room 3, Smoke Detector SD-312” triggering immediate CO2 suppression in that specific room while keeping rest of building operational. Zero casualties, minimal equipment damage, no building-wide evacuation needed.
Modern addressable systems like NFire AIoT go beyond basic addressability by adding artificial intelligence and IoT connectivity:
Beyond just detection, intelligent addressable systems address the most common compliance failures:
Problem: Manual fire drill and system test documentation often incomplete
AIoT Solution:
Problem: Weekly/monthly testing often skipped or not documented
AIoT Solution:
Problem: Reactive maintenance after complete failure
AIoT Solution:
Problem: Siloed fire safety systems don’t communicate with building management
AIoT Solution:
Problem: Critical minutes lost identifying fire location
AIoT Solution:
Challenge: 12-story IT park with conventional 8-zone system faced frequent false alarms (40+ per year) and struggled with NBC 2016 documentation requirements.
Solution: NFire AIoT addressable system with 240 intelligent detectors, cloud connectivity, and BMS integration.
Results:
Challenge: 200-bed hospital needed NBC 2016-compliant horizontal evacuation strategy with fire-rated compartments but lacked precise detection in patient areas.
Solution: NFire AIoT with device-level detection in each patient room, corridor, and service area. Integration with nurse call systems and automated door releases.
Results:
Challenge: 28-floor residential tower needed NBC 2025 compliance ahead of expected code adoption. Existing conventional system had 15+ false alarms annually causing resident complaints.
Solution: NFire AIoT addressable system with 400+ devices, resident mobile app, and multi-criteria detection algorithms.
Results:
Complete Replacement Needed:
Phased Upgrade Possible:
Hybrid Approach:
Upfront Costs: Addressable systems typically cost 1.8-2.5x conventional systems initially, but:
Long-Term Savings:
Typical ROI: 3-5 years for commercial buildings, 4-6 years for residential
Phase 1: Assessment (2-4 weeks)
Phase 2: Design (3-6 weeks)
Phase 3: Installation (6-12 weeks depending on building size)
Phase 4: Optimization (Ongoing)
Use this quick assessment to determine your upgrade urgency:
If you answered “NO” to 2 or more: Your system likely needs upgrade for NBC 2025 compliance
If you answered “NO” to 2 or more: AIoT integration could significantly improve your compliance posture
If you answered “NO” to 2 or more: Modern addressable systems would reduce your operational burden
If you answered “NO” to 2 or more: Consider upgrading sooner rather than later
Reality: While upfront costs are higher, TCO (Total Cost of Ownership) over 10 years is often lower due to reduced false alarms, maintenance efficiency, and insurance benefits. Financing options and phased implementation make it accessible for most budgets.
Reality: Modern addressable systems are actually easier to maintain than conventional systems. Precise fault identification means less diagnostic time. Many issues can be resolved remotely. Comprehensive training programs ensure staff competency.
Reality: Experienced integrators can implement zone-by-zone, maintaining fire safety throughout. Most installations complete in 6-12 weeks with minimal disruption. Critical areas can be scheduled during off-hours.
Reality: NBC 2025 will likely mandate upgrades regardless of system age. Early adoption provides competitive advantage, insurance benefits, and avoids rushed last-minute compliance upgrades when code is finalized.
Reality: Addressable systems can be installed in buildings of any age. Wireless addressable options exist for heritage or challenging buildings. Integration is designed to work with existing infrastructure where possible.
