An automatic dry standpipe system is typically found in what type of buildings?

An automatic dry standpipe system is specifically designed to be used in unheated buildings. These systems are particularly useful in environments where the risk of freezing water could damage the system and render it ineffective during a fire emergency.

Unheated buildings often lack climate control, which means that water within a wet standpipe system could freeze, making it unusable when needed. The dry standpipe system, which is filled with air rather than water until needed, mitigates this risk. When a fire occurs, firefighters can connect their hose to the standpipe and supply water from a nearby source, ensuring that they have effective firefighting capabilities without the danger of frozen pipes.

Therefore, the defining characteristic of dry standpipe systems being suited for unheated buildings highlights their critical role in maintaining fire safety in environments where climate control is not present.
