Fire Detection & Alarm
Smoke, Heat and Gas Detection in Bangladesh
Smoke, heat and gas detection means choosing the right sensor for each space so a fire or leak is found early without constant false alarms. A standard smoke detector fails in a dusty cutting room, a kitchen or a tall warehouse. Matching detectors to the hazard is what makes an alarm system trustworthy.

Scope
What’s included.
Everything below is done by our own engineers and installation team, so one company answers for the result.
- Hazard review of every room and process
- Detector selection and spacing layout
- Beam detectors for high-bay warehouses
- Aspirating detection for dusty or critical rooms
- Heat detectors for kitchens and boiler rooms
- Natural gas and LPG detectors with shut-off valves
- Integration with addressable or conventional panels
- Commissioning with test smoke, heat or gas
Which detector suits which space?
Optical smoke detectors suit offices, corridors and most clean rooms. Heat detectors suit kitchens, generator rooms and boiler houses, where smoke or steam is normal. Multi-sensor detectors combine both and reject many nuisance alarms. High warehouse roofs suit beam detectors, which send an infrared beam across the space and alarm when smoke obscures it.
Aspirating systems draw air through sampling pipes to a sensitive detector. They suit dusty textile areas with filtration, and server rooms where very early warning matters, often before a clean agent system discharges. Flame detectors see the infrared or ultraviolet signature of flame directly and suit fuel stores and open process areas where a fire may flare without much smoke.
Why does gas detection need different placement?
Because gases behave differently. Natural gas from the piped supply is lighter than air and collects near the ceiling, so its detectors go high. LPG from cylinders is heavier than air and pools near the floor, so its detectors go low, near the cylinders and appliances. Placing them the wrong way round is a common, dangerous mistake.
A gas detector can do more than sound an alarm. Linked to a solenoid valve, it can shut off the gas supply automatically, and it can start exhaust fans to clear the room. In boiler rooms and generator houses, we also check where ventilation openings are, because airflow changes where gas collects.
What causes false alarms, and how do we avoid them?
Most false alarms come from the wrong detector in the wrong place: smoke detectors over cooking, near steam presses or beside air diffusers, or in dust from cutting and spinning. Each false alarm teaches staff to ignore the next one.
We review every room's activity before choosing detectors, and keep detectors away from airflow that dilutes smoke. On addressable systems, sensitivity and alarm verification add a second layer of control. When a site already suffers repeated false alarms, we read the panel log, find which devices trigger and why, and replace or relocate those detectors rather than disabling them.
How it’s done
How we deliver it, step by step.
- 01
Review the hazards
We walk each area and note dust, steam, cooking, ceiling height, airflow and gas use.
- 02
Select detectors
Each area gets a detector type and spacing that fits its hazard and ceiling.
- 03
Install and align
Detectors are mounted, beam units aligned and aspirating pipes balanced to the design.
- 04
Prove with tests
Each detector is tested with smoke, heat or calibrated test gas and recorded.
Price guide
What sets the price.
Every site is different, so we price from a survey, not a rate card. These are the factors that move the number, and the written quote shows each one.
- Mix of detector types across the site
- Ceiling heights and access equipment needed
- Number of beam or aspirating units
- Gas types, detector count and shut-off valves
- Interface with the existing fire alarm panel

Frequently asked questions
Standard smoke and heat detectors are the lowest-cost devices. Beam, aspirating, flame and gas detectors cost more per unit but can cover difficult spaces with fewer devices. The total depends on the mix, the ceiling heights and how they connect to your panel. We price from a site survey.
A heat detector, not a smoke detector. Cooking produces smoke and steam that would trigger constant false alarms. Commercial kitchens with LPG cylinders should also have LPG detectors mounted low, and cooking hoods may need a wet chemical suppression system under NFPA 17A.
Point detectors on a tall roof respond slowly, because smoke cools and spreads before it reaches them. Optical beam detectors and aspirating systems are the usual choices. The right one depends on roof height, racking layout and whether forklifts or roof structure could block a beam.
Follow the manufacturer's calibration interval, which depends on the sensor type and environment. Gas sensors drift and lose sensitivity with age, so they should be bump-tested with test gas regularly and recalibrated or replaced on schedule. Keep a record for each detector.
