Addressable fire alarm system communicates directly to each device so in the event of a fire, the panel displays the exact location, allowing the fire to be located more quickly. More suitable for larger or higher risk sites, they can also be linked over many buildings to make one larger system

are more convinient to install, sometimes require wireless extenders, cost could be a little higher to both install and maintain due to batteries. Better for larger and listed buildings or outbuildings and great for temporary deployments.
