Metro (subway) stations operate fire-protection equipment under harsh conditions (vibration, dust, humidity, 24/7). NFPA 130 applies to fixed guideway systems, and NFPA 25 governs ITM. Istanbul, London and Paris metros follow strict daily/weekly discipline.

- Jockey pump: running pressure check
- Fire alarm: random smoke test on 1 detector
- Smoke damper: 1/8 zone manual
- PA system: announcement test
Monthly Tests
- Standpipe: pressure-flow check
- Electric pump: 10-min flow test
