Which component of the dry pipe valve routes water to the alarm system after the clapper is open?

• A. A. Clapper latch assembly
• B. B. Intermediate chamber
• C. C. Water motor alarm
• D. D. Restricted orifice

Answer: (B)

The intermediate chamber is essential for the operation of a dry pipe valve system, particularly in how it functions with the alarm system. When the clapper within the dry pipe valve opens—triggered by the decrease in pressure caused by a fire event—the intermediate chamber provides a pathway for water to flow into the alarm system. This chamber serves as a transitional area where the water can be directed, activating the alarm to signal that water has entered the system in response to a fire condition. The importance of the intermediate chamber lies in its role in ensuring that the alarm can effectively notify occupants of a fire emergency as soon as the system is activated. Without it, the alarm would not receive the water flow necessary to function, compromising the entire fire protection system. Therefore, understanding the intermediate chamber's role clarifies how fire alarm systems integrate with sprinkler components to enhance safety and response effectiveness.
