Power checks

Make sure the primary and secondary power supplies are charged and providing the correct voltage.

Make sure the primary and secondary power supplies are correctly connected to the jet interface
modules.

Check the voltage for each of the following:

Primary battery to port jet interface module.

Secondary battery to port jet interface module.

Primary battery to starboard jet interface module.

Secondary battery to starboard jet interface module.
The voltage should be 24V but a range of 18-32V will allow the system to operate.

Switch the power on to the control system.

Switch off the primary supply and make sure the system gets power from the secondary power supply.

Switch off the secondary power supply and make sure the system gets power from the primary power
supply.

Make sure that the station control panels still get power if either the port or starboard jet interface
modules are lost.
General checks

Make sure that the station control panel can still communicate with both jet interface modules:

If one of the two cables between the jet interface module and the station control panel is
disconnected.

If the cable between jet interface modules is disconnected.

Check that the alarm sounder is correctly attached.

Check all necessary relays, sensors and circuit breakers are correctly installed.
If all installation checks are acceptable, continue with system commissioning.
