Fire Alarm Systems
Fire alarm system installation is one of the few building services where the design has to satisfy three different audiences at once: the occupants who need to get out, the state fire authority that issues your NOC, and the insurer whose surveyor will ask why a particular detector sits where it does. Foxnet Securitas designs, installs, commissions and maintains conventional and addressable fire detection systems for offices, factories, hospitals, data centres and warehousing across India, working with panels and field devices from EST, Notifier, Honeywell and Edwards. We take the system from cause-and-effect matrix through to the documentation pack your fire officer actually asks for.
What we deliver
- Addressable and conventional fire alarm system design sized to the building — detector spacing, zoning and loop loading worked out against the occupancy class rather than copied from a previous project.
- Panel supply, installation and commissioning using EST, Notifier, Honeywell and Edwards equipment, including networked panels where a campus needs several buildings reporting to one graphical head end.
- A written cause-and-effect matrix that defines exactly what each detector, each zone and each manual call point triggers — sounders, magnetic door releases, lift homing, AHU and damper shutdown, and the public address or voice alarm system.
- Fire alarm systems for office fit-outs where the base building already has a landlord panel, including interfacing your tenant floor devices back into the base build loop without orphaning either system.
- Integration with access control so that egress doors release on a confirmed alarm, and with CCTV so the command centre gets the camera view of the zone in alarm rather than a beeping panel and no context.
- Support through the state fire NOC process — drawings, equipment datasheets, test certificates and the completion documentation that the fire department reviews before issuing or renewing approval.
- Fire alarm AMC covering scheduled functional testing, detector cleaning and sensitivity checks, battery load testing, panel firmware and event log review, and a written test report you can hand to an auditor.
- Retrofit and phased replacement in occupied buildings, sequenced floor by floor or wing by wing so the building is never left without detection coverage overnight.
- Spares planning and end-of-life advice, so a panel that is approaching obsolescence is flagged before the day a board fails and the replacement is a twelve-week import.
How a Foxnet deployment works
1. Site survey and requirement capture. Our engineers walk the building with the architectural and services drawings, recording ceiling heights, void depths, occupancy class, hazardous or dusty areas, existing panel make and age, and the routes available for fire-survival cable. We also capture who currently holds the fire NOC and when it expires, because that dictates the sequence of everything that follows.
2. Design and BoQ. We produce zone drawings, a device schedule, loop loading calculations, battery standby sizing and the cause-and-effect matrix, then price it as a line-item bill of quantities. Where addressable and conventional both work, we show you both costs honestly rather than defaulting to the more expensive architecture.
3. Installation and commissioning. Containment and fire-survival cabling go in first, then devices, then the panel. Commissioning is device-by-device: every detector is tested with the appropriate stimulus, every call point operated, every interface output proven against the matrix, and the results recorded on a signed test schedule rather than a verbal confirmation.
4. Handover, training and documentation. You receive as-built zone drawings, the device address schedule, the cause-and-effect matrix, panel operating instructions and the commissioning test records. We train the security team and the facilities engineer on silencing, resetting, isolating a device for hot work, and reading the event log before calling anyone.
5. AMC and ongoing support. The system moves onto a scheduled maintenance programme with periodic functional testing, battery checks and detector servicing, plus reactive attendance for faults. Each visit produces a dated report, so when the fire officer or the insurance surveyor asks for the maintenance history there is a file to hand over.
Technical specifications and standards
The reference points below are the standards and design parameters the equipment and the installation are designed against. They are properties of the standards bodies and the manufacturers, not claims about Foxnet.
| Parameter | Reference point |
|---|---|
| Detection and alarm code of practice | IS 2189 — the Indian code of practice for selection, installation and maintenance of automatic fire detection and alarm systems, covering detector spacing, zoning and audibility. |
| Building code | National Building Code of India 2016, Part 4 (Fire and Life Safety) — occupancy classification, compartmentation, means of escape and the detection provisions expected per occupancy. |
| Panel architecture | Conventional zoned panels (devices grouped per zone circuit) versus addressable loop panels (each device individually addressed and reported). Loop capacity is typically stated per manufacturer, commonly in the region of 99–250 addresses per loop. |
| Detector types | Optical/photoelectric smoke, fixed-temperature and rate-of-rise heat, multi-criteria, projected beam for atria and warehouses, and aspirating detection for data halls and high-airflow spaces. |
| Notification appliances | Sounders and combined sounder-beacons selected on rated sound pressure level at one metre and on coverage volume; visual alarm devices are specified where ambient noise or hearing-impaired occupancy makes audible-only notification insufficient. |
| Cabling | Fire-survival and FRLS cable on detection and sounder circuits, segregated from power cabling, with loop wiring installed as a true return path so a single break does not disable the circuit. |
| Standby power | Sealed lead-acid battery sets sized for a quiescent standby period followed by a full alarm load period, calculated from the actual device count rather than assumed from panel size. |
| Interfaces and outputs | Addressable input/output modules and potential-free contacts for door release, lift homing to the fire recall floor, AHU and damper shutdown, fire pump status, and triggering of zoned voice evacuation messages. |
| Insurance considerations | TAC (Tariff Advisory Committee) fire protection guidance is frequently referenced by Indian insurers when rating a risk; equipment approval status and installation practice are both commonly examined during survey. |
| Special environments | Ingress-rated and flameproof device variants for dusty, wet or hazardous-classified areas in manufacturing and warehousing, where standard ceiling detectors would generate persistent false alarms. |
Where we deploy
Foxnet Securitas has field teams across 15+ Indian cities, including Delhi NCR, Noida, Gurgaon, Mumbai, Pune, Bangalore, Hyderabad, Kolkata, Chennai and Ahmedabad. Clients searching for fire alarm system dealers in Delhi usually discover the same thing once they scale: buying a panel is easy, but getting it commissioned, documented and re-tested every quarter across several sites is where single-city vendors run out of reach.
Fire NOC requirements are administered by state fire services, and the process genuinely differs from state to state — the forms, the fee structure, the drawing conventions, the inspecting authority's thresholds for building height and occupancy, and the renewal cycle are not uniform across Maharashtra, Karnataka, Telangana, Tamil Nadu, West Bengal, Haryana and Delhi. For a client with a plant in Pune, a development centre in Bangalore and a head office in Gurgaon, that is three different approval conversations. This is the practical argument for one integrator holding the design standard and the documentation set nationally, while local teams handle each authority.
Our multi-city work usually sits alongside the rest of the life-safety and security stack. At Avalara in Pune, a roughly 90,000 sq ft facility, we delivered cloud access control and CCTV — the kind of estate where fire detection, door release and camera call-up have to be considered as one interlocked system rather than three separate procurements. Regulated environments raise the bar further; our work with Sber Bank in Bangalore was a banking-grade security transformation where auditability of every system change mattered as much as the hardware itself.
Indicative investment
Fire alarm cost is driven by device count, panel architecture and cable route difficulty far more than by brand. The figures below are indicative ranges only — actual pricing depends on site survey.
| Tier | Typical scope | Indicative range (INR) |
|---|---|---|
| Small office | Single floor or small tenancy, conventional 4–8 zone panel, 40–120 devices, sounders and call points. | ₹1.5 lakh – ₹5 lakh |
| Mid-size building or campus | Addressable panel with two to four loops, 300–900 devices, interfaces to lifts, HVAC and access control, plus voice evacuation on key floors. | ₹9 lakh – ₹45 lakh |
| Enterprise multi-site | Networked panels across several buildings or cities, graphical head end, aspirating detection in critical rooms, standardised documentation across states. | ₹50 lakh – ₹2.5 crore+ |
Cost moves up with addressable architecture, aspirating or beam detection, voice evacuation, hazardous-area device variants, work restricted to night shifts in occupied buildings, and long fire-survival cable routes through finished ceilings. Cost moves down on new-build projects where containment can be laid before ceilings close, on repeat standard designs across sites, and where an existing loop is sound enough to reuse. AMC is quoted separately, typically as an annual percentage of installed system value, with the percentage depending on visit frequency, site count and whether spares holding is included.
Frequently asked questions
What is the difference between a conventional and an addressable fire alarm system?
A conventional panel groups detectors onto zone circuits, so an alarm tells you which zone is affected but not which device. An addressable panel gives every detector, call point and module its own address on a loop, so the panel reports the exact device and location, and can report dirt, drift and faults per device. Conventional suits small, simple premises; addressable suits anything where search time or per-device diagnostics matter.
What documentation is needed for a state fire NOC?
Typically the fire authority wants building and services drawings showing detection and escape provisions, equipment datasheets and approval documents, a zone plan, installation and commissioning test certificates, and confirmation that the system is under maintenance. Requirements differ by state, so the exact form set, fee and inspection sequence in Maharashtra will not match Karnataka or Delhi. We prepare the technical pack; the application itself is filed by the building owner or occupier.
How often should fire alarm AMC visits happen, and what does a statutory inspection cover?
Most Indian sites run quarterly preventive visits, with monthly in-house call point and sounder checks logged by the facilities team. A visit covers functional testing of a rotating sample of detectors, all call points, sounder audibility, battery load test, panel fault and event log review, interface outputs against the cause-and-effect matrix, and detector cleaning. Each visit ends with a dated, signed test report retained for inspection.
Can the fire alarm panel release access-controlled doors automatically?
Yes, and on escape routes it should. The panel drives a potential-free contact into the access control system or directly into the lock power supply, so that on a confirmed alarm the doors on the designated escape path unlock. Fail-safe locking is used where egress must be guaranteed, and the release logic is written into the cause-and-effect matrix and proven during commissioning, not assumed.
Can a fire alarm system be retrofitted in an occupied building?
Routinely. The work is phased so that every occupied area keeps working detection at the end of each shift, usually by running the new loop alongside the old system and cutting over floor by floor. Noisy and dusty activity is scheduled outside working hours, temporary detection covers any gap, and every isolation is logged and lifted before the site is handed back for the day.
Can one integrator handle fire alarm systems across several states?
That is the main reason multi-site clients consolidate. Foxnet Securitas has field teams across 15+ Indian cities, so the same design standard, the same panel platform and the same documentation format apply at every site, while local engineers deal with each state fire service. It removes the situation where three cities produce three incompatible systems and three different maintenance records.
