May 29, 2024 · They detect smoke, heat, or flames, alert occupants to evacuate, and notify emergency services. Understanding the different types of fire alarm systems can help you choose the right one for your needs. This guide will introduce you to five common types of fire alarm systems and their applications.
- 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.
Oct 8, 2024 · The different categories and subcategories of fire alarm systems provide varying levels of protection based on specific needs and risks. The M category includes manual systems, while the L and P categories focus on automatic detection and warning systems.
- Ionization
- Photoelectric
- Heat
- Combined Ionization and Photoelectric
- Two-Wire Fire Alarm Systems
- Wireless Fire Alarm Systems
- Conventional Fire Alarm Systems
- Analogue-Addressable Fire Alarm Systems
- Hybrid Fire Alarms
- Aspirating Smoke Detection Systems
Ionization smoke detectors rely on a constant electrical current. This current runs between two electrically charged plates within the device and is only disrupted when smoke enters. When this happens, it triggers an alarm signal to signal a fire. Typically, this fire alarm is touted for detecting fast-burning fires fast.
Photoelectric smoke detectors operate similarly to ionization detectors, however, instead of electricity, they rely on a laser beam. This light is scattered when it encounters smoke, signaling the alarm to sound. This is an incredibly reliable fire alarm that works well with small fires.
Heat detectors signal an alarm when they sense a change in air temperature due to flames. However, since it's temperature-reliant, these alarms do experience false alarms due to humidity or steam. For this reason, these are most often relied upon in storage facilities or warehouses.
A go-to in the industry, a hybrid of ionization and the photoelectric detector is often deemed the best option on the market. With both an electrical current and a light beam, this device is one of the fastest you can get, detecting smoke rapidly to sound a warning alarm. Fire alarm systems can be categorized into two types of commercial fire alarm...
A two-wire fire alarm is founded on the standard conventional system, however, it utilizes a two-wire system. With this structure, the call points, detectors, and alarm devices are wired to two zone cables, going back to the fire alarm control panel. This two-wire system allows for increased flexibility that also has additional benefits like detect...
With a wireless system, you'll have a fire alarm without cables connecting the detection device to the fire alarm panel. This system relies on multi-frequency links for heightened functionality, maintaining signal strength for constant protection. This system may be more expensive to purchase, but it's more flexible and quicker to install. Plus, it...
What is a conventional fire alarm system? It is a type of fire alarm system whose devices and panels are hardwired individually to the fire alarm control panel. A conventional fire alarm system is a 4-wire system that is frequently used in smaller properties. This system divides space into different detection zones, with each wired to a dedicated c...
The definition of an addressable fire alarm system is an intelligent system whose components are connected to each other and the control unit. An addressable fire alarm system allows you to set manual and automatic alarms in distinct parts of the building. Unlike conventional systemsthat share a detected fire based on the zone, analog-addressable s...
Hybrid fire alarm systems are the perfect combination because they allow the hardwired and wireless detection systems to work in harmony to create a more customized and efficient whole. In other words, if something damages the wires of the conventional system the addressable system can come in as a reliable backup.
One of the more sensitive fire detection options you can choose from, an aspirating system can pick up on extremely small fires much quicker than other systems. It does so with a fan that pulls in air from the building, which then passes through a pipe system, and a detector that checks for any signs of potential smoke particles. While it's highly ...
- Conventional Fire Alarm Systems. Functionality: In a conventional system, devices like detectors and manual call points are connected to the zones’ fire alarm control panel.
- Addressable (or Intelligent) Fire Alarm Systems. Functionality: Each device in this system has a unique address, and they’re all connected to the main control panel using a loop.
- Analog Addressable Fire Alarm Systems. Functionality: These are advanced versions of addressable systems. They can measure the environment in detail and provide data to the control panel.
- Wireless (or Radio) Fire Alarm Systems. Functionality: Instead of using physical cables, these systems use radio signals to communicate between the control panel and the individual alarm system components.
These systems can be broadly categorised into two main categories: those designed to protect life and those intended to protect property. Understanding the different categories and their specifications can help you determine which fire alarm system is best suited for your specific needs.
