IN THE CASE OF FIRE-FIGHTING MODULES WITH DIESEL MOTORS
Restarting tests.
1) Restart the diesel pump immediately after it stops, by pressing the "START" manual starting test button.
2) Press the "STOP" button on the electric panel to stop the pump.
During the test:
- check the oil pressure (using the pressure gauges, when applicable, or another suitable measuring device).
- check the temperature of the motor and the coolant liquid.
- check the oil pipes.
- perform a general inspection to check for any leaks (of the fuel, coolant, exhaust fumes, etc.).
Check correct operation of all the heating and ventilation systems required to guarantee the correct environmental conditions for
the unit.

 Check that the secondary supply of power provided by the Diesel generators is correct.
 Check the efficiency of the flow meters.
5.2.4 Biannual check
Each part of the biannual check must be performed at a frequency of no more than every six months.
These are (EN12845 para 20.3.3):
 Check the dry alarm valves and the other components of the system.
