Integlex Multicrest N3060:

UL listed analog addressable fire alarm system with 10.4 inch larger color touch screen and versatile informative display modes. The system is networkable up to 64 nodes with maximum 12 SLC and 255 addressable devices per SLC capacity.


Integlex Multicrest S508:

UL listed analog addressable fire alarm system with maximum 4 SLC and 127 addressable devices per SLC.




UL / FM Listed aspirating early smoke detector with maximum coverage of 2400 / 2000 m2 and a bar graph display of smoke density on its display unit. Air-conditioning has a tendency to dilute and diffuse smoke and fumes, making the prompt detection of fire difficult thereby requiring recognizing the early signs of fire for protection of critical or irreplaceable items. The system was developed for use in locations where it is particularly necessary to prevent fire damage such as, rooms housing computers, servers and telecommunication equipment, national assets, and clean rooms.





The UL listed fire suppression system employs nitrogen gas and has storage cylinder valve with in-built function of discharge pressure control. The nitrogen gas occupies 78% of the air and has no adverse effect on the natural environment. It does not produce any toxic gases even when in contact with fire, making it safe for the user. The product uses side wall type discharge nozzles which provide flexibility when compared to the pendant type discharged nozzle.

The fire protection products market in India

Raghavan: There are many small & medium size integrator companies which are into installation of fire systems. They are supplied products by various global and local manufacturers. As per the recent Frost & Sullivan report, the fire and safety market is estimated to have earned revenue of approximately INR 12000 crores. Around 60% of the business was generated through sales of detection devices and the remaining came from suppression products. Currently, the total market is estimated to be growing at CAGR of 16.7% with the detection segment (consisting of fire and gas detection systems) growing at a CAGR of 15.4% and the suppression segment (comprising water-based, gas-based, and special suppression systems) growing at a CAGR of 18.5%.

Importance of Integrated Fire Systems

Takahira: Fire is a focused field and needs specialized fire engineers to look at all aspects of safety before, during and after the installation. Fire Systems need to be integrated, like the detection with suppression, smoke extract fans or even pre action
systems to reduce water damage in certain cases. There is also a need to create a cause & effect in many cases when the system is being designed. It is preferable to have the fire design made during the planning stages so that safety codes can be followed
in totality which also includes passive clear Fire exits,clear distance from the road for the fire vehicles to go around the building in case of any emergency.

India specific challenges

Raghavan: The major challenge industry faces in India is the delayed revisions of fire safety standards to keep pace with changes as compared to International standards. Most of the Indian standards have been adopted either form British Standards or NFPA. National Building Codes which is adopted by most of the states – as Fire rules are set by individual states has not been revised since 2005. While, some individual states have formulated their own Fire Standards depending on local requirements, MNC’s in India either follow NFPA or FM standards. However, the awareness is growing and many public institutions like hospitals and IT companies etc. are relooking at their fire systems.

The other challenge is that of getting skilled manpower. There are institutes which are training fire engineers; however, with the growth of the industry we need more institute’s which can train people. Currently even after an engineer is recruited he needs to be given substantial amount of training by the companies. Also, most of the engineers, Project Engineers/ Managers do not prefer to work in smaller cities.

Last but not the least, maintenance is a very important aspect for which regular equipment check is required. States like Maharashtra now mandates Fire licenses for installers approved by the relevant authorities and regular audits of the fire systems. We are hopeful that many more states will follow this practice.

What are some of the latest technologies & systems in fire protection segment?

Takahira: One of the latest technology is the automatic detection and suppression system which is used in high atrium areas. Atriums has always been a challenge for all designers as sprinklers are not effective in high ceiling areas. There are window sprinklers which need to be installed in buildings with glass facades. The new Cabinet based Gas Suppression system for smaller rooms are useful for completed projects where they have changed the occupancy or in case there is a need for gas suppression in high hazard small areas like telecom rooms or Base station sites.

Given the buildings are structurally & functionally getting complex, what are the essential fire safety systems?

Raghavan: The basic fire system consists of Fire Hydrants, First Aid Hose Reel systems, Sprinklers, Fire Detection systems and Gas suppression for High Asset rooms. Buildings with glass facade and atriums need to be treated with care as this could be a major fire hazard because of smoke spreading in case of a fire. Areas like basement parking needs sprinklers or foam systems. Transformers in building needs to be protected with high velocity water spray systems. The smoke extract system needs to be designed in case of high rise buildings. The cables need to be Fire Survival for critical circuits & fire stops should be applied to stop fire spread in the buildings. Fire Rated doors need to be provided at all entries & exits.

Company growth strategy for India

Takahira: Nohmi in India is mostly in execution of industrial projects and is working on many local commercial & industrial projects. Nohmi Bosai has regional offices in Mumbai, Bangalore & Chennai. We plan to make India as a major hub for providing design services across Asia and have recruited some very senior and experienced people to strengthen our presence in India in addition to our Japanese staff who come with major project execution & design experience. Iswar I.S. who has considerable experience in designing complex systems and who has considerable knowledge on both Indian
and International Codes and Standards has joined our team. Swarjita has joined our team in Mumbai as Regional Manager – West & Venkat has joined in as Regional Manager – South. Sooraj K has been recruited for product sales and he would be appointing distributors across India.

The company has recently launched Protecview Aspirating High Smoke Detection System & had already installed it in some major installation in India. Integlex Multicrest fire Alarm system another new launch is a system that is expandable up to 12 loops and has a large 10.4 inches colour touch screen. This is networkable & could be linked to graphics for large complexes.
