What kind of buildings primarily use non-coded alarm systems?

Non-coded alarm systems are typically found in older, small buildings due to several factors. These buildings often have simpler layouts and lower occupancy levels, making it less critical to have a sophisticated communication system that includes coded alarms. Such buildings may utilize conventional alarm systems that simply trigger alarms without the complex protocols associated with coded systems, which are designed to convey specific information to trained personnel during emergencies.

In contrast, larger commercial buildings, hospitals, and newer public facilities generally require more advanced fire alarm systems. These environments often have complex layouts, higher occupancy densities, and specific safety regulations to adhere to, leading them to implement coded systems capable of providing detailed information during emergencies. Thus, the use of a non-coded alarm system is more aligned with the needs and characteristics of old, small buildings rather than those found in more complex or large public structures.
