How many smoke detectors are on the OFCR on the B777-300?

Explanation:
Smoke detection in a crew rest area is designed with multiple zones so smoke in any part of the space is detected quickly. The OFCR on the Boeing 777-300 is arranged so that each zone within the crew rest area is monitored by its own detector, including the separate sleeping compartments and the surrounding access/interaction areas. This comprehensive coverage results in six detectors in total, ensuring rapid warning from any location inside the OFCR. If a configuration had fewer detectors, some zones wouldn’t be monitored as effectively, while more detectors would not match the standard layout for this aircraft.
