Components of fire Alarm system

Components of fire Alarm system

Basic Fire Alarm System Components
  • Fire alarm initiating devices
  • Fire notification devices
  • Fire alarm control panel
  • Primary power supply
  • Backup power supply

Fire Alarm Initiating Devices

The role of the alarm initiating devices in a fire alarm system is to activate the system when a fire occurs. There are two types of fire alarm initiating devices are 
Manual initiating devices
Automatic initiating devices

Manual initiating devices

Manual initiating devices need to be well marked and accessible to make it easy to identify and use. These devices include pull stations, break glass stations or buttons that need to be manually activated by someone in the building when they identify a fire. 

Automatic initiating devices

Automatic initiation devices trigger the fire alarm system automatically when a fire happens. These devices include heat, flame and smoke detection. When heat, flames or smoke is detected, the devices send a signal to a central control panel that activates the system.

Fire Notification Devices

The role of notification devices in an alarm system is to notify building occupants when a fire is detected. Some fire alarm notification devices include in Bells, Strobes, Horns, Chimes

Fire Alarm Control Panel

The fire alarm control panel is the central hub of the fire alarm and detection system. The control panel acts as the brain of the alarm system by monitoring and managing the initiation devices. When an initiation device is triggered, a signal is sent to the control panel and the control panel activates the notification devices. The status of the system is displayed on the control panel and allows you to see when an issue is detected and allows you to control it manually.

Primary Power Supply

The primary power supply for your fire alarm system is supplied by your power company. The primary power supply is typically 120- or 240-volt AC power sources.

Backup Power Supply

In the event of a power failure, the fire alarm system still needs to work in order to alert people if a fire occurs. A backup power supply is an important part of any fire alarm and detection system. The backup power supply includes 6- or 12-volt batteries to keep the system running when a power failure happens.

Other Important Components are 

  • Sprinkler systems
  • Exit lighting
  • Alarm monitoring
  • Voice communication systems
  • Remote controls and display panels

Sprinkler systems

When a fire is detected, the fire sprinkler system is activated to suppress or extinguish a fire.

Exit lighting

When a fire occurs, people need to be able to get out safely. Having a lights to show people how to exit safely is very important.

Alarm monitoring

Having a monitored fire alarm system alerts the authorities when the fire alarm system is activated.

Voice communication systems

Voice communication systems give verbal commands to building occupants telling them what to do during an emergency situation. Voice communication is especially helpful in high rise buildings, arenas and hospitals.

Remote controls and display panels

In a larger building such as a high rise building with a lot of floors, having remote controls and display panels throughout the building can be helpful. These devices allow personnel to easily check, activate, and deactivate alarms from remote part of the building.
