In residential and commercial settings, fire alarm systems serve as indispensable tools for detecting and promptly notifying individuals of fire emergencies. Conventional and addressable fire alarm control panels (FACPs) are the two prominent choices available. Given the severe hazard fires present to life, property, and financial stability, it is essential to choose an appropriate fire alarm system to ensure the safety of your organization and all individuals within its premises. Selecting the right system will ultimately depend on the fire safety needs of your home or business, as well as your budget.
Conventional fire alarm systems will partition different areas in your building into multiple zones along a circuit called the initiating device circuit (IDC). During an alarm, the panel will recognize different zones in your building without knowing which specific device in that zone triggered the alarm. Meanwhile, addressable fire alarm control panels utilize the signaling line circuit (SLC) for input devices, and are considered more ‘intelligent’. Accordingly, they can report which device or detector in your building triggered the alarm and monitor device state. Due to their digital signaling, addressable systems have more advanced functionality and therefore are able to perform functions and services that aren’t possible with a conventional FACP.
While they have a higher upfront cost, addressable systems are considered safer and more advanced than conventional ones. The point identification of an addressable alarm system means that you can pinpoint the precise location of a disaster and fire professionals can respond more quickly to an incident. As a result, system reliability and maintenance is simpler, since devices may report faults and can be quickly serviced. While conventional systems can save you costs in the short term from not having to upgrade, addressable systems can increase the speed of responding to a fire, which can save lives and your business.
For Medium – Large buildings
If you are building a new fire alarm system or you are looking to upgrade, we recommend that you choose an addressable FACP. Not only can this potentially be cheaper in the long run due to less expensive installation and cabling, but it can also provide more flexibility and quicker response times to disasters. Moreover these types of systems have more programming options and can address complex safety needs.
For Small – Medium Buildings
If you are looking to protect a small home or office with a limited budget, a conventional panel will likely suit your needs. While conventional panels are good enough to protect small buildings, they face more limitations when it comes to medium to large sites. With longer radial circuits, it will be much easier to expend your entire budget on the cabling required to support a larger facility.
Ultimately, your selection of the FACP will be contingent upon the size and requirements of the premises. Moreover, factors such as occupancy class, your fire safety strategy, and your state / local fire codes will all influence the final decision regarding which components to select.
In the event of a faulty wire or device, an addressable system will be able to detect the problem and quickly send a notification to the control panel, along with the location of the faulty device. Additionally, subsequent devices in the circuit loop will still be active in an addressable system. In comparison, a conventional system will lose access to the connected zone without notifying the panel. As a result, addressable systems are much more fault tolerant and can allow you to address problems more quickly.
Installing an addressable system can help to reduce costly false alarms. While addressable systems can’t address tampering or ventilation issues directly, they promptly report detector issues and can adjust alert thresholds due to accumulating dust or contaminants. Additionally, the digital signal of an addressable system is less prone to interference compared to conventional analog circuits.
Care homes necessitate addressable fire alarm systems to meet the maximum life safety standards. As such, you must ensure prompt evacuation by assigning detectors unique addresses, aiding fire safety professionals in quickly locating alerted rooms to evacuate vulnerable occupants.
A conventional fire alarm system has multiple alarm zones, with each capable of accommodating up to 32 devices within a limited distance. Conversely, an addressable system offers the capacity to encompass broader areas and accommodate more devices.
Addressable systems are highly scalable because they require less overall cabling material, and they can locate faulty devices for servicing. Besides being much less expensive to expand your system, addressable systems also help fire professionals respond much more rapidly in the case of an emergency.
Meanwhile, conventional systems require much more cabling than addressable systems, which is becomes more apparent in large facilities. This is due to each zone being a large radial circuit that connects directly to the control panel. The installation for these devices will be more complex and costly, especially if you have a growing business with changing requirements. As your system grows in size, it will become more difficult to maintain and pinpoint the location of an alarm.
A zone is a designated area of the building. When a fire detector triggers an alarm state, a conventional system is unable to identify the precise fire location, indicating only the general zone. For instance, in a three-story building where each floor serves as a zone, the system would only signal which floor the fire is on, without specifying the exact room or location.
An addressable panel will have a single loop of wire connecting each device to the control panel. As a result, if the circuit wire is cut in one location, your other detectors will still remain active.
Conversely, a conventional panel has a single length of cable linking each detector to the next. This cable starts at the control panel and terminates at the last connected detector. Furthermore, conventional panel may have separate circuits running in parallel. Consequently, if a wire is cut, every following device in the circuit will be disconnected from the main control panel.
Due to its modern digital signaling, an addressable panel may have more advanced features than a conventional one. Some of these features include:
