How many fire extinguishers are associated with the avionics smoke detection system?

The avionics smoke detection system on the A320 is designed to provide alerts regarding potentially hazardous conditions in the avionics compartment. However, it is essential to note that this system does not include a specific fire suppression mechanism, such as a fire extinguisher. Instead, the system primarily focuses on detecting smoke and alerting the flight crew to the presence of smoke, allowing them to take appropriate action if necessary.

In this context, stating that there are "none" directly correlates to the fact that the system relies on detection without the incorporation of fire extinguishing equipment specific to the avionics area. Fire extinguishers are typically located elsewhere in the aircraft for general use, rather than being exclusively tied to the avionics smoke detection system.
