Which component is primarily responsible for releasing contents in the Freon bottle discharge system when activated?

• A. The frangible disk ruptures due to a release valve.
• B. The valve opens manually.
• C. A pressure sensor triggers venting.
• D. The frangible disk ruptures due to an explosive squib.

Answer: (D)

The release is accomplished by rupturing a frangible disk with an explosive squib. When the system is activated, an electrical squib fires and provides the rapid, focused impulse that breaks the disk. Once the disk is ruptured, the extinguishing agent can flow quickly into the discharge line and into the space being protected. The valve isn’t the primary release mechanism, nor is a manual act or a pressure sensor-triggered venting used to release the contents in normal operation. The squib-driven disk rupture is deliberate to ensure immediate, complete discharge.
