A conventional system, ideal for smaller buildings, uses single radial wiring into fire alarm zones or sounder circuits. It's a simple solution, indicating which zone the fire or fault is in, and cheaper. Addressable systems use a loop configuration, in which devices continuously communicate throughout the system, showing exactly where a problem is on the control panel, saving valuable time in an emergency. Addressable systems can accommodate more alarms and zones, and can be expanded indefinitely, making it the best choice for medium to large settings. Our range includes everything needed for either system, sourced from trusted brands.
