TYPES OF FIRE ALARM SYSTEMS____________

Addressable Fire Alarm System

Addressable Fire Alarm Systems are more advanced and provide more detailed information about the location of the fire or fault. Each device connected to the system, such as detectors, call points, or modules, has a unique address. When activated, the system can pinpoint the exact location of the device that triggered the alarm. This enables quicker response times and simplifies troubleshooting. Addressable systems are commonly used in larger buildings, such as commercial complexes and high-rise structures. An addressable fire alarm system works by having every detection and notification device connected to each other and to the addressable fire alarm control panel. An addressable system sends digital signals in binary code, as opposed to a conventional fire alarm system which operates through electrical currents. Addressable systems operate like a computer and convert variations in voltage to binary code, various combinations of zeros and ones. This allows for an addressable fire alarm system to transfer critical information to the control panel with a broader range of information. An addressable system can pinpoint the exact location of smoke or fire, providing an increased level of safety and reliability. Because an addressable fire alarm system consists of several devices all individually identified and connected, advanced configuration allows for greater flexibility. Various protocols can be established for any mix of detection devices, input, or output modules. Addressable fire alarm control panels employ Signaling Line Currents, commonly referred to as SLC loops or just loops, allowing monitoring of just a few devices to several hundred. More complex fire alarm systems could employ multiple Signaling Line Currents. Quick recognition of detection location provides many benefits such as helping first responders know exactly where to go and providing quick evacuation in the most jeopardized and adjacent areas. This quicker response to saving lives has to be the greatest benefit of addressable fire alarm systems. Additional benefits of addressable fire alarm systems over conventional systems include improved reliability and reduced false alarms. Addressable systems also help to diagnose any component malfunction with self-monitoring capabilities for quicker repairs and consistent protection. While a conventional system may cost less up front, an addressable system could be less costly to install with less expenses for wiring, and can provide for easier, less expensive upgrades and maintenance in the future. With the flexibility and scalability of addressable systems, you can easily add new zones without disrupting operation.
