Fire Detection & Alarm
System Design (FDAS)
Code-compliant fire detection and alarm system design for all building types — from concept to construction-ready drawings, cause & effect matrix, BOQ and specifications aligned with NFPA 72, BS 5839 and NBC India.
What We Offer
Fire detection and alarm system design is a life-safety critical discipline that requires specialist knowledge of detection technology, alarm signalling, evacuation strategy and regulatory compliance. ASDV Consultant provides professional FDAS design services ensuring every building meets the requirements of applicable fire codes and authority having jurisdiction (AHJ).
We design conventional, addressable (2-wire loop) and analogue addressable fire alarm systems for all occupancy types including commercial offices, residential towers, hotels, hospitals, industrial plants, data centres, warehouses and educational institutions. Our designs cover detector placement (heat, smoke, beam, aspirating), manual call points, sounders, strobes, fire alarm control panels (FACP), voice evacuation integration and connection to building fire suppression systems.
Every FDAS design is accompanied by a Cause and Effect (C&E) Matrix defining the response of all fire alarm zones to initiating events — including HVAC shutdown, elevator recall, door hold-open release, damper operation and suppression system activation.

What's Included
Our Design Process
Code Analysis
Identify applicable codes (NFPA 72, BS 5839, NBC India) and AHJ requirements based on building type, occupancy and jurisdiction.
Concept Design
Develop detection strategy, zoning plan, FACP location, evacuation strategy and system type (conventional vs addressable) for client approval.
Detector Placement Design
Calculate detector spacing per code, produce floor plan layouts with device locations, cable routes and conduit sizing.
C&E Matrix & Schematics
Prepare cause & effect matrix, riser diagrams, FACP terminal schedules and system schematics.
BOQ & Specifications
Produce itemised BOQ and vendor-neutral technical specifications for tendering.
Tender & Construction Support
Answer contractor RFIs, review submittals, conduct site visits and review commissioning test reports.

Frequently Asked Questions
A conventional fire alarm system divides the building into zones, identifying which zone is in alarm but not the specific device. An addressable system assigns a unique address to every device, enabling the FACP to identify the exact detector or MCP in alarm. Addressable systems are recommended for buildings with more than 2 floors, complex occupancies or where rapid evacuation response is critical.
A C&E Matrix is a table that defines the response of every controlled system to every initiating event in the fire alarm system. For example: 'Smoke detector in Server Room Zone 2 in alarm → FACP output: activate pre-action suppression, shut down HVAC AHU-02, release magnetic door holder at Fire Door FD-102, send signal to BMS.' It ensures the complete fire response strategy is documented and tested.
The primary standards are NBC India 2016 (National Building Code, Part 4 — Fire & Life Safety), IS 2189 (Indian Standard for fire detection and alarm systems), and NFPA 72 (widely adopted for international and premium projects). Many projects in India also reference BS 5839 for UK-standard specifications.
Yes. Aspirating smoke detection (ASD/ASD-L/VESDA) is specified for high-value areas requiring early warning — server rooms, heritage buildings, clean rooms, warehouses with high rack storage and areas where conventional point detectors are impractical. We specify VESDA, FAAST and equivalent systems.
Yes. High-rise fire alarm design involves networked, addressable systems with staged evacuation zones, voice evacuation (PAVA) integration, firefighter telephone systems, elevator recall, pressurisation system interfaces and compliance with NBC India 2016 high-rise requirements and local fire department approval.
