Common Fire Alarm Parts

Fire alarm systems are only as good as the parts they are built with. Commercial fire alarm systems are comprised of much more than a standard wall-mounted smoke detector. In general, there are only a few classes of devices which are as follow: Fire Alarm Control Panels, Initiating Devices, Notification Devices and accessories that extend system capabilities.

Here’s a quick rundown of some major fire alarm system parts and their purpose.
Fire Alarm Parts & Devices

  • Fire Alarm Control Panels
    • Fire Alarm Control Panels are the heart of the system.
  • Initiating Devices
    • Initiating Devices are the parts of a fire alarm system which trigger alarms.  Devices in this group include manual pull stations, CO detectors, Smoke Detectors, IR Sensors, Heat detectors and Light Sensors; to name a few.
  • Notification Devices
    • Notification Devices alert the occupants of a building or infrastructure in the event a fire or other emergency.  Today’s modern fire alarms utilize both visual and auditory beacons.  Often notification devices are integrated with other audio components like PA systems and intercoms.
  • Standard Manual Pull Stations can be activated by any passing individual who senses or spots a fire before an alarm does.
  • Strobe Lights and Horns are essential in any large building or complex, be it a school, store or office.
  • Duct Smoke Detectors are placed in air ducts to detect smoke within them—a standard for any multiple story building with a ventilation system.
  • Heat Detectors are necessary for sections of a building that experience intense heat such as large kitchens and boiler rooms.
  • Carbon Monoxide Detectors, which sense the release of escaping carbon monoxide, should be installed on or near rooms containing any gas-utilizing appliances or machinery.
  • Intercoms, coupled with fully customizable paging capabilities, allow for immediate and easy communication between all levels of a building.
  • The Warden Phone is a recommended addition, used to contact your district fire warden in the actual event of a fire.
  • Emergency Shutdown Devices for machinery (such as fans and elevators) are absolutely crucial for larger buildings and facilities with a high volume of human traffic.
  • This elaborate web of communication and data is automatically controlled from the fire-alarm panel. This control device uses an LCD display to reveal messages in an alphanumeric code that describes an assortment of actions and conditions of your fire alarm system.
