What is allowed in a system consisting of slave cylinders?

In a system that utilizes slave cylinders, the correct understanding involves knowing the function and requirements of these cylinders. Slave cylinders are designed to enhance the distribution of the extinguishing agent and can be activated without the need for manual operation. Therefore, it is permissible to use slave cylinders that do not have manual actuators. This design allows for automatic activation and helps ensure efficient operation in fire suppression scenarios.

The absence of a manual actuator on slave cylinders contributes to the versatility of the system, especially in instances where rapid response is crucial. The design of having slave cylinders operate automatically simplifies the overall system and allows for effective fire control without the physical intervention of personnel at the time of activation.

In contrast, other options pertain to specific operational requirements that are not in line with the intended use of slave cylinders, which are designed for automated response in conjunction with primary cylinders that may have manual activation capabilities. Understanding these distinctions is essential for implementing effective dry chemical extinguishing systems following the NFPA 17 standards.
