Mar 3, 2021 · A visual guide and discussion on the major components of a fire alarm system.
- Fire Alarm Control Panel
- Initiating Devices
- Notification Devices
This is the center of the fire alarm system. The fire alarm control panel monitors initiating devices and then activates notification devices when an alarm signal is received. These panels range in scale from a single zone to multiple buildings.
Initiating devices detect a fire emergency and communicate it to the fire alarm control panel. These can be triggered both manually (pull stations), as well as automatically in a response to heat, smoke or flame. When one of these initiating devices is triggered, the control panel will go into an alarm state. Another type of initiating device is a ...
After the control panel receives a signal for an initiating device and goes into an alarm state, the panel initiates output devices that signal to building occupants that there is an emergency situation. These include bells, horns, speakers, chimes, strobes and flashing lights that signal either audibly or visually that there is a fire emergency. A...
- Fire Alarm Control Panel. The fire alarm control panel, commonly abbreviated as FACU, is the system’s “brain.” It receives messages from the initiating devices, also known as inputs, and performs the following functions.
- Initiation Devices. Initiation devices initiate alarms, and, just like alarm panels, they can be either addressable or non-addressable. Some initiation devices, like water flow switches, are traditionally non-addressable, but connect with addressable modules.
- Pull Stations. A pull station is probably the fire alarm system component you’re most familiar with. It’s a manually operated device that initiates an alarm signal when someone pulls its handle.
- Smoke Detectors. A smoke detector is a device that initiates an alarm signal when it senses smoke. There are two classifications of these devices, depending on the type of sensor they use to detect smoke particles.

- Fire Detection. Most of us are familiar with smoke and heat detectors because these devices are installed in our homes. Detecting a fire is typically accomplished by installing smoke and/or heat detectors, manual pull stations and automatic sprinkler system water flow switches.
- Occupant Notification. When it comes to warning building occupants of a fire, you need both audible and visible alarms. Audible alarms include horns (the appliance that produces that loud and very annoying sound) or speakers that play a pre-recorded message and/or allow emergency responders to provide spoken instructions to the occupants.
- Control Functions. There are many different types of control functions that the components of a basic fire alarm system perform. The activation of a duct mounted smoke detector will shut down the heating ventilation and air conditioning (HVAC) equipment to prevent the migration of smoke to non-affected areas of the building.
- Fire Department Notification. The codes require that fire alarm signals be automatically transmitted directly to the local fire department, or to a central station monitoring service, notifying the fire department of the emergency.
Aug 7, 2020 · In essence, a fire alarm system has four key functions: detect, alert, monitor, and control. These sophisticated systems use a network of devices, appliances, and control panels to carry out these four functions.
A fire alarm system is a building system designed to detect, alert occupants, and alert emergency forces of the presence of fire, smoke, carbon monoxide, or other fire-related emergencies. Fire alarm systems are required in most commercial buildings.
