FIRE DETECTION


We offer to our client an automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is either classified as automatic, manually activated, or both. Automatic fire alarm systems can be used to notify people to evacuate in the event of a fire or other emergency.

The fire detection system aims to monitor for the presence of fire to alert and allow control actions to be initiated manually or automatically to minimize the likelihood of fire escalation and the probability of people being exposed and to minimize the probability of a fire condition to develop and escalate.

A fire detection system is a network of sensors installed in a building designed to detect the presence of fire by sensing smoke, heat, or flames, and then trigger an alarm to alert occupants and emergency services about a potential fire, allowing for early intervention and evacuation. 

 
Key points about fire detection:
  • Types of detectors:
    • Smoke detectors: Most common, detect smoke particles in the air, further categorized as photoelectric (better for smoldering fires) and ionization (better for fast-burning flames). 
       
    • Heat detectors: Activate when a significant temperature increase is detected, suitable for areas where smoke detection might be unreliable like kitchens. 
       
    • Beam detectors: Utilize a light beam to detect smoke across large open spaces. 
       
    • Gas detectors: Specifically designed to identify flammable gases like propane or carbon monoxide, which can indicate a potential fire source. 
       
  • How they work:
    • Smoke detectors: When smoke enters the sensing chamber, it disrupts a light beam, triggering the alarm. 
       
    • Heat detectors: A temperature-sensitive element within the detector activates when the temperature exceeds a preset threshold. 
       
    • Beam detectors: An interruption in the light beam between the emitter and receiver triggers the alarm. 
       
  • Fire detection system components:
    • Sensors: The actual detection devices (smoke, heat, beam detectors) 
       
    • Control panel: The central unit that receives signals from the detectors, processes information, and initiates alarms 
       
    • Notification devices: Audible alarms (bells, horns) and visual indicators (strobing lights) 
       
  • Important considerations:
    • Location placement: Detectors should be strategically positioned based on fire risk and building layout. 
       
    • Maintenance and testing: Regular testing and cleaning are crucial to ensure proper functionality. 
       
    • Building codes: Most jurisdictions have building codes dictating the required fire detection system for different types of structures.
