  - (3) **Engine-room fire.**
  - (4) **High bilge-level.**
  - (5) **Low lube-oil pressure for each main propulsion engine and each prime mover of a generator.**
  - (6) **For each main propulsion engine and each prime mover of a generator—**
    - (i) High lube-oil temperature; and
    - (ii) **High jacket-water temperature.**
  - (7) **For each reduction gear and each turbocharger with a pressurized oil system—**
    - (i) Low lube-oil pressure; and
    - (ii) **High lube-oil temperature.**
  - (8) **Loss of normal power for the alarms listed in paragraphs (a)(1) through (a)(7) of this section.**
- (b) Sensors for the high-bilge-level alarm required by [paragraph (a)(4)](#a-4) of this section must be installed in—
  - (1) Each space below the deepest load waterline that contains pumps, motors, or electrical equipment; and
  - (2) **The compartment that contains the rudder post.**
