Fusible plugs are fixed temperature heat detectors thatmelt at the required temperature.
Fire detection is due to loss of air/gas pressure in thefusible plug loop.
Melt point is 203 DegF (95 DegC) on AWPs
Melt point is 160 DegF (71 DegC) on APP

The Fire Water Manifold is pressurized at 10 barg by utility waterpumps. When the pressure drops to 6.5 barg or ConfirmedFire/Gas the first Fire Water Pump in the preset start sequencestarts. If the manifold pressure do not build to 10 barg in 30seconds, the second pump starts. If the manifold pressure still
does not reach 10 barg in another 30 seconds, the third pumpstarts. If 1st FW pump start and build pressure to 10 barg within 30s. 2nd
FW pump will not start But if the pressure drop below 10 barg after 30s. 2nd pump will start.
After 2nd pump start, if pressure drop below 10 barg, 3rd pump willstart. (With 30 seconds delay after 2nd pump started)
This logic is to prevent FW pumps start consecutively within 30seconds
