What is the main purpose of the intermediate chamber in a dry pipe system?

The intermediate chamber in a dry pipe system is primarily designed to accommodate any potential leaks within the system. This chamber acts as a buffer, allowing the system to maintain the necessary air pressure without resulting in water entering the system prematurely. By providing this space, the intermediate chamber helps ensure that, in the event of a leak, additional air can fill the chamber without compromising the overall functionality of the dry pipe sprinkler system. This feature is vital for maintaining the integrity of the system, ensuring that it will perform as intended when activated, while also minimizing the risk of false alarms or water damage prior to an actual fire event.
