How Does a Fire Alarm System Work?

There are various options for setting up a modern and sophisticated fire protection system for buildings in Singapore, but do you know the basic ideas behind such systems?

Let’s break down the basics of the fire alarm systems used in buildings.

Smoke or Heat Detection
A fire protection system has sensors that detect smoke or heat levels, because these are the first indicators of a fire. Most detectors used in fire alarm systems in Singapore are either ionization detectors or optical detectors. The ionization detectors look for signs of smoke before it triggers the alarm. The smoke is detected through the chamber of the ionization. An optical detector on the other hand looks for signs of smoke using infrared LED sensors to trigger the alarm.

Bell or Siren
The bell or siren system alerts the people in the building that smoke has been detected and a possible fire may be ongoing. The detectors will send the signal to trigger the alarm. The type of alarm used in a fire protection system may vary, but most buildings in Singapore use bells, sirens, and flashing or blinking lights.

Other Monitors
Modern fire protection system in Singapore also consists of other monitors or detectors besides those already mentioned, because sometimes looking for signs of smoke may not be adequate in large buildings. For example, some fire alarm systems also include carbon monoxide detectors.

Sprinkler and Suppression Systems
A fire protection system for large buildings in Singapore may also include a dry pipe sprinkler system that discharges water when smoke is detected, and the alarms are triggered. In other fire alarm systems, a clean agent is used in rooms that house electronic equipment, because water will not work in such cases. This is an advanced fire prevention method to minimize losses as much as possible while waiting for response from the fire department.

Danger Notification
Not only are sophisticated fire alarm systems used to notify people of fires, but it can also be a means to alert people of other dangers and emergencies. The fire protection system can be connected to a notification system with speakers and other alarm systems to alert people of security threats, weather disturbances, and evacuation procedures.

Control Panel
A fire protection system’s primary purpose is to alert the people in the building and the authorities of a possible fire. The control panel serves as the brain of the entire fire protection system and is housed in a specific are in the building. In some cases, fire alarm systems may be set of manually if there are threats that were not detected by the system. Triggering this will cause the notification system to send signals to alert the occupants and authorities to take action.

Your fire alarm system provider might also recommend zoning and fire alarm categories depending on the size and complexity of the building and the number of occupants or residents.
