Narrative:

Approaching destination the first officer left his seat to stretch and await the flight attendant to enter the cockpit for a restroom break. As he stood up; his head struck one of the agent toggle switches on the cargo smoke overhead panel. Approximately 15-30 seconds later; the 'smoke fwd cargo smoke' ECAM appeared momentarily. After further observation we noticed that the 'DISCH1' light was illuminated on the cargo smoke panel; indicating that the 1st bottle of smoke retardant had been fired into the forward cargo pit. After reviewing the flight manual and discussing the situation; we determined that the ECAM was the result of retardant being inadvertently discharged into the forward cargo pit. Upon taxi-in the second bottle automatically discharged itself into the forward cargo pit. Once parked at the gate we were met by a maintenance supervisor. After our debriefing with the maintenance supervisor; I spoke to flight operations and was told sufficient action had been taken on our part; but we should still file a report.
