How many manual actuators are required for self-contained skid-mounted systems?

For self-contained skid-mounted systems, the requirement is for one manual actuator. This single manual actuator is essential as it allows for manual activation of the dry chemical extinguishing system, providing a direct means for personnel to engage the system in the event of a fire. The presence of a single manual actuator ensures that operators have an accessible and straightforward way to initiate the extinguishing process without having to rely solely on automatic systems or other methods.

Requiring just one actuator simplifies the design and installation of the system while still meeting safety standards. This setup is particularly important in environments where quick manual intervention is necessary to control or extinguish fires effectively.
