Purpose
To identify the presence of hazardous gases—flammable, toxic, or oxygen-depleting—and issue alerts before gas levels become dangerous.
Gases Commonly Detected
- Flammable gases: LPG, Methane, Propane, Hydrogen
- Toxic gases: Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), Ammonia (NH₃), Chlorine (Cl₂)
- Oxygen monitoring: For confined spaces—detects O₂ depletion or enrichment
Types of Gas Detectors
| Detector Type | Sensing Principle | Typical Use |
|---|---|---|
| Catalytic Bead | Heat of combustion | Flammable gas detection |
| Infrared (IR) | IR absorption | Hydrocarbons in hazardous zones |
| Electrochemical | Voltage from chemical reaction | Toxic gases like CO, H₂S |
| Semiconductor | Change in conductivity | General air quality monitoring |
| PID (Photoionization) | UV ionization of VOCs | Volatile organic compound detection |
Key Features
- Local and remote alarms
- Integration with exhaust/ventilation systems
- Continuous real-time monitoring
- Data logging and trend analysis
FIRE DETECTION SYSTEM
Purpose
To detect fire or smoke at the earliest stage and trigger alarms or suppression systems to prevent damage and injury.
Types of Fire Detectors
| Detector Type | What It Detects | Ideal For |
|---|---|---|
| Smoke Detector | Smoke particles (optical/ionized) | Offices, clean rooms, residences |
| Heat Detector | Sudden rise in temperature | Kitchens, warehouses |
| Flame Detector | UV/IR flame radiation | Refineries, turbines, fuel storage |
| Multi-Sensor Detector | Combination of smoke & heat | General industrial applications |
| Aspirating System (VESDA) | Smoke particles in air samples | Data centers, telecom rooms, museums |
Alarm & Response Mechanisms
- Fire alarm control panels (FACP)
- Hooters/sounders
- Manual call points (MCPs)
- Automatic suppression triggers (sprinkler/gas systems)
INTEGRATED GAS + FIRE DETECTION
For high-risk environments such as oil & gas facilities, chemical plants, battery storage units, and paint booths, both systems are often integrated for complete safety coverage.
Key Integration Features:
- Combined control panels for unified monitoring
- Automated exhaust or equipment shutdown
- BMS/SCADA system connectivity for remote alerts and automation
APPLICATION AREAS
| Environment | Recommended Systems |
|---|---|
| Battery Rooms | Hydrogen gas detectors, smoke/heat sensors |
| Chemical Factories | Toxic gas sensors, flame detectors |
| Server/Data Centers | VESDA smoke detection, clean agent suppression |
| Commercial Kitchens | Heat sensors, gas leak detectors, flame sensors |
| Underground Parking Areas | Carbon monoxide sensors, smoke detectors |
