Fire detection and alarm systems can be complex or simple. The level of complexity is focused around what hazards require protection and what are the most effective means of providing protection and instructing people to evacuate a building, or portion thereof.A fire alarm system monitoring a small 2-story office building is not going to have the same level of complexity as a multi-use, multimillion-square-foot resort complex. The office building has occupants who are generally familiar with the environment and would recognize horn/strobe notification appliances as an abnormal condition that would require attention, leading to evacuation. A large casino resort hotel gaming complex has different types of occupants, different hazards, and unique conditions that may require evacuating only portions of the building.
