- 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.
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. They may include smoke detectors, heat detectors, and manual fire alarm activation devices ...

The fire alarm control panel functions as the central brain of your entire fire alarm and detection system. It monitors and controls the systems initiation devices. When an initiation device is triggered, it sends a signal to the control panel, which activates the notification devices or the alarm. The control panel also allows you to manually cont...
Initiating devices are responsible for activating the system in an emergency. There are two categories of initiating devices, including manual and automatic. Manual initiating devices require you to pull a switch or handle to initiate the alarm physically. Automatic initiation devices activate automatically upon detecting heat, smoke, flames, or ga...
Notification devices notify building occupants that a fire or emergency has been detected. They can be programmed to deliver visual and audible messages relevant to different emergencies and should include: 1. Strobes 2. Alarms 3. Bells 4. Horns 5. Sirens 6. Chimes 7. Voice Evacuation
The majority of fire alarm systems need a primary and backup power supply. The primary power supply usually comes from a 120- or 240- Volt AC power source that your property’s power company supplies.
As mentioned above fire alarm system also need a backup power supply just in case the primary power fails or is shut off. A backup power supply will typically consist of 6- or 12- volt batteries to ensure your fire alarm system continues to run when the primary power is out.

Aug 7, 2020 · The fire alarm panel is connected to the system’s initiating devices through either 2- or 4-wire circuits. This circuitry allows the control panel to monitor the state of its initiating devices, usually by zones, identifying whether the devices are in normal or alarm mode. The control panel shows these readings on its display panel.
Alarm initiating devices in a fire alarm system activate the system when a fire occurs. There are two types of fire alarm initiating devices: 1. Manual initiating device – These types of devices must be manually activated by a person in the building when they identify a fire emergency —they include pull stations, break glass stations or ...
