FAPA stands for Fire Alarm and Public Address — the detection, alarm and voice communication systems that warn occupants and guide evacuation during a fire.

Should FAPA be done by the same contractor as the fire fighting system?

It helps. Most of our FAPA work is delivered together with fire protection, which avoids interface gaps between the alarm panel, sprinkler flow switches and pumps.

Addressable or conventional?

Addressable systems identify the exact device in alarm and suit larger or multi-tower buildings. Conventional systems are simpler and suit small occupancies. We recommend based on building size and occupancy, not on what is easiest to sell.

Basement ventilation that clears the air — and the smoke.

Basement ventilation contractors in Hyderabad — jet fan and ducted systems, CO monitoring and smoke extraction, designed for the basement and balanced on site.

A basement is the one place in a building where ventilation is not about comfort. It is about carbon monoxide and smoke.

SASNIK EM designs and installs basement ventilation for residential towers, commercial buildings and industrial facilities across Hyderabad — jet fan systems, ducted supply and exhaust, CO monitoring and smoke extraction.

A basement system has two jobs: hold carbon monoxide within limits day to day, and clear smoke quickly during a fire. We design for both, and balance the system on site rather than assuming the fans will do what the catalogue says.

Standards & approach

Air-change based designSized to the basement, not a rule of thumb

CO monitoringSensors interlocked with fan staging

Balanced on siteAirflow measured at handover

Scope

What's included.

Jet fan systemsInduction fans that move air without a full duct network, laid out for the basement's shape.
Ducted supply & exhaustSupply and extract ducting where jet fans alone will not reach.
Smoke extractionFire-rated fans and dampers that clear smoke from escape routes.
CO monitoring & interlockSensors that stage the fans up and down with actual carbon monoxide levels.
Shafts, louvres & dampersIntake and discharge routes coordinated with the structure.
Testing, balancing & handoverAirflow measured and balanced, with records handed over.

FAQ

Questions clients ask.

Do you do basement ventilation along with HVAC?

Yes. On most projects it sits in the same mechanical package, which keeps shafts, fans and controls coordinated with the rest of the system.

Jet fans or ducted ventilation?

Jet fans suit most car park basements and avoid a full duct network. Ducted systems suit basements with obstructions or a layout that breaks up airflow. The geometry decides it.

Does the system handle smoke as well as carbon monoxide?

It should. We design so the same infrastructure handles day-to-day CO extraction and smoke clearance during a fire, with fire-rated fans and dampers where required.
