How Fire-Detection System Work

Keeping the safety of the business facility is one of the significant responsibilities that one should manage to integrate every once in a while, since it upholds the well-being of the people inside the building. Let’s take for example a fire-detection system or fire alarm; it is a network of initiating and notification devices connected to a control panel that alerts people to an emergency in a building. The purpose of installing a fire alarm is to arrange to three fundamental safety procedures namely: to immediately send alerts to a control panel, the authorities, and building occupants so each can take the appropriate action.

Smoke alarms provide an early warning of a fire, giving people additional escape time. In 2009-2013, smoke alarms sounded in more than half (53%) of the home fires reported to U.S. fire departments. This statistical data describes the importance of fire alarms around residential areas specifically to places that are open to any hazardous materials and is prone to accidents just like how fire can quickly spread in any field. It is fundamental to know the different core functions of how to use a fire-detection system; this enables every establishment to test and see if it is useful for a quicker evacuation that affects every single person inside the building.

In this article, we will discuss the different ways how a fire alarm works, and the things that you should do to maintain the reliability of your fire-detection system.

How Fire-Detection System Work

Types of Smoke Detectors

  1. Optical Detectors – Sensors detect specific levels of heat or smoke that could be an indication of fire. Optical smoke detectors discover smoke by using infrared LED light sensors. When the identified smoke reaches the internal indicators of the system, it will eventually scatter light and will trigger the alarm to blare out signals for the public.
  2. Ionization Detectors – This type of smoke detectors has a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.

 

How to Maintain your Fire-Detection System

  • Check the Age of your Fire Alarm – It is essential to know if your fire-detection device is up to date with how your operations inside the establishment circulate; this is one crucial part of maintaining a fire alarm since most don’t have the leisure and resources to replace their old detection systems. But risking a quality fire-detection system to an obsolete fire detection system could cause chaos inside your facility. Temperature, humidity and even voltage fluctuations can produce components of your system to break down over time. The older a system gets; the more maintenance work will need to be done to them for them to function normally.
  • Annual Tests – Conducting tests during the period of installation and annual professional check-up is also needed to keep the usability of the detection system. To perform these tests and calibration, you will need to know about the specific sensors of the unit, failure modes, and re-installation requirements before testing the system.
  • Connection to Fire and Rescue – It is essential to check if your fire alarm is connected to the nearest fire and rescue station. One method of connection used to be a direct monitored line which used to be called a PW (dedicated private wire/line).

A fire alarm system is an active fire protection system that controls all the fire alarm modules in a building. It is vital for facility owners and managers to have the knowledge and time to maintain every bit of the available fire-detection system in the area, to preserve life, and to minimize unmanageable evacuation during active alarms.
