Smoke & Heat Detctor

Key Features

1. Dual Detection Sensors:

   • Smoke Detection: Uses photoelectric or ionization technology to detect smoke particles.
   • Heat Detection: Monitors temperature changes using fixed-temperature or rate-of-rise heat sensors.

2. High Sensitivity with Reduced False Alarms:

   • Designed to minimize false alarms caused by cooking smoke, dust, or steam by requiring both smoke and heat thresholds to be met before activation.

3. Wide Coverage:

   • Covers larger areas and offers reliable performance in challenging environments.

4. Integration with Fire Alarm Systems:

   • Compatible with conventional and addressable fire alarm systems for centralized monitoring.

5. Self-Diagnostics:

   • Continuously monitors its own functionality and alerts to faults or maintenance needs.

6. LED Indicators:

   • Visual indicators for power, fault, and alarm status.

7. Built-In Sounder (Optional):

   • Some models include integrated audible alarms for local notification.

8. Battery Backup (Standalone Models):

   • Provides operation during power outages for standalone detectors.

9. Durable Construction:

   • Designed to operate reliably in various environmental conditions, including areas with high humidity or dust.

Applications

• Residential Areas:

  • Ideal for homes where a single detector type might not suffice, such as kitchens or garages.

• Commercial Buildings:

  • Offices, hotels, and retail spaces where comprehensive fire detection is essential.

• Industrial Settings:

  • Factories, warehouses, and workshops with varying fire risks.

• Public Spaces:

  • Hospitals, schools, theaters, and transportation hubs for enhanced fire safety.

Advantages of Combined Heat and Smoke Detectors

1. Comprehensive Detection:

   • Detects both smoke and heat, increasing reliability in identifying different types of fires.

2. Flexible Installation:

   • Suitable for diverse environments, including spaces prone to false alarms like kitchens or boiler rooms.

3. Cost-Effective:

   • Combines two detection technologies in one unit, reducing installation costs and space requirements.

4. Reduced False Alarms:

   • Advanced algorithms minimize nuisance triggers while maintaining high sensitivity to actual fire conditions.

5. Regulatory Compliance:

   • Meets fire safety standards for residential, commercial, and industrial use.

Types of Combined Heat and Smoke Detectors

1. Conventional Detectors:

   • Wired into specific zones on a fire alarm control panel. Ideal for smaller buildings.

2. Addressable Detectors:

   • Each device has a unique address, allowing precise identification of the location of an alarm or fault. Suitable for large or complex buildings.

3. Standalone Detectors:

   • Battery-powered models designed for independent use, ideal for small residential applications.

How to Use and Maintain Combined Detectors

1. Installation:

   • Mount detectors on ceilings or high walls in accordance with fire safety regulations and manufacturer guidelines.

2. Testing:

   • Test the detector monthly using the built-in test button or an external test device.

3. Cleaning:

   • Clean the detector regularly to remove dust, cobwebs, and debris that might affect performance.

4. Battery Replacement:

   • Replace batteries in standalone detectors as needed, typically once a year or when the low-battery indicator activates.

5. Replacement:

   • Replace the detector every 10 years or as recommended by the manufacturer.

How It Works

1. Normal Conditions:

   • The detector continuously monitors the environment for smoke particles and temperature changes.

2. Smoke Detection:

   • If smoke particles scatter the light in a photoelectric sensor or disrupt the ionization process in an ionization sensor, the alarm is triggered.

3. Heat Detection:

   • If the temperature exceeds a set threshold (fixed-temperature) or rises rapidly (rate-of-rise), the alarm is triggered.

4. Dual Activation:

   • Some models require both smoke and heat criteria to be met before activating, reducing false alarms in sensitive areas.
