FIRE DETECTION AND NOTIFICATION SYSTEMS

In principle, fire detection and alarm systems are divided into conventional and addressable systems. Conventional systems are designed to control relatively small spaces. Addressable detection and alarm systems are used where the spaces are larger, the risk is differentiated, and point detection is vital.

Fire Detection System aims to alert people in the environment as quickly as possible by detecting smoke, heat, combined detectors, Flame Detectors, which are positioned against the danger of fire in an environment. In this way, loss of life and property is greatly prevented.

In a facility insured against fire, property losses can be covered by the insurance company. However, if fire detection and notification systems, extinguishing systems are not installed

  • The time required for the facility to become operational
  • Fixed production – Unfulfilled orders
  • The period of examination and investigation required for the insurance to make a payment

will be recorded in the loss line of the enterprise.

When fire detection and notification systems and extinguishing systems are installed, there will be a significant reduction in fire insurance premiums. Thus, the investment made in these systems will return to the business coffers in approximately 3-5 years.

What is the purpose of Fire Detection and Notification Systems?

  • Early Detection; smoke, heat, flame, flammable- combustible gas, etc.
  • Identify and show the starting point of the fire clearly and accurately
  • Sound and light alarm
  • Control/ command and communication capability
  • Activating the extinguishing

Fire Detection System Design Principles:

A Fire Detection and Alarm System is designed by taking into account the architectural structure, usage and fire risks of the building or facility where the system will be installed for the specified purposes. Basically ;

  • Regulation on Fire Protection of Buildings / Turkey (2021)
  • EN 54/14 Fire Detection and Notification Systems Design and Application – 2018
  • BS5839 Part 1 British Fire Alarm System Design and Application Standard
  • NFPA 72 US Fire Alarm System Design and Application Standard

It is designed in accordance with one of the standards listed above. EN54/14 standard is valid in our country.

Fire Alarm and Detection System Types

  • Conventional Systems – Makes local notification
  • Addressable Systems – Provides spot and, if desired, regional notification

 

Conventional Systems (Regional Notification)

  • Independent wiring of a separate circuit to each zone
  • 20 -30 detectors and buttons in each circuit
  • Fire or fault warning is received on zone basis
  • If detail is needed, it is necessary to increase the zones
  • Limited use
  • Applicable for small spaces

 

Addressable Systems ( Spot Notification)

  • 100-126 detectors and buttons in one loop (Existing Classic Systems)
  • 250 detectors and buttons for one cycle (Next Generation systems)
  • Zones not connected to loops
  • Zones are defined with software on the panel
  • Individual recognition of an alerting or malfunctioning device
  • The address of the fire is clearly determined
  • Loop length varies according to the manufacturer (1000 – 1500 – 2000m)
  • Sensing cable cross-section 1x2x0.8mm – 1x2x1mm – 1x2x1.5mm
  • Widespread installation and use
  • Easy fault detection
  • Panel production with fixed or expandable loop option
  • Detectors can give pre-alarm
  • Pre-alarm and alarm threshold levels of detectors can be set
  • Detectors can warn of contamination and maintenance
  • Detectors can auto-calibrate their sensitivity
  • In case of a short circuit in the loop line, preventing the entire line from collapsing thanks to integrated or independent isolator modules integrated into the sensing elements
  • Networking between Control Panels
  • Possibility to make detailed programs
  • Graphic software capability
  • Remote access via software
  • Pairing and control with mobile phones

 

 

Challenges related to the Use of Fire Detection Systems

Today, a problem we frequently encounter with the use of fire detection systems is the false detection of these systems. In other words, the system perceives and evaluates a normal situation as a fire. In case of incorrect detector selection and incorrect detector placement, false detection is mostly caused by bad environmental conditions and environmental factors. Some of these factors are given below.

 

  • Dirty and dusty environments
  • Humid or water vapor environments
  • Areas with other liquid vapors
  • Electromagnetic interference and high frequencies
  • Cigarette smoke
  • Exhaust gases from vehicles
  • Natural phases of production such as smoke, heat, flame present in the environment, but deceptive fire symptoms
  • Airborne cotton and yarn particles in the textile industry

 

Addressable Fire Alarm System Components:

  • Detection and Notification Panels
  • Detection Detectors
  • Special Detectors
  • Zener Barrier/Galvanic Barrier
  • Control/operation/monitoring modules
  • Buttons
  • Siren/ Flasher Siren/Bell
  • Isolator ????
  • Energy Source
  • Emergency Lighting
  • Emergency Routing
  • Flammable-Explosive-Explosive Gas Detection
  • Announcement Systems
  • Detection and Warning Wiring
  • Data wiring
  • Supply Wiring
