What is the primary function of the manual actuator in a dry chemical system?

The primary function of the manual actuator in a dry chemical system is to allow for manual control of the system. This means that, in the event of a fire, an operator can directly initiate the discharge of the dry chemical extinguishing agent when deemed necessary. This manual intervention is crucial in situations where automatic activation may not be suitable or may not occur quickly enough to address an emerging fire.

Furthermore, having a manual actuator provides flexibility and decision-making power to the operator, who can assess the fire risk and make a judgment call on the best timing for system activation. This element of human control is essential in ensuring that actions taken are appropriate for the specific circumstances surrounding a fire incident.
