On board your yacht there is a fire detection unit that can identify anomalous situations and diagnose them. It has a wide range of signals: alarm, pre-alarm, fault, warning, exclusion, tests, monitor. All reports are visible both and on display on both LEDs.
Each detection unit is equipped with its own output of alarm repetition, allowing the alarm to be repeated on the monitoring system.
Both the smoke control unit and the signal light/acoustic alarm unit are supplied with a buffer battery, in this way danger can be detected even without power supply.
If the main 24V power supply of the control unit should fail, the malfunction is indicated visually (alarm warning light) on its control panel.
If both power supplies (main and buffer battery) should fail, the control unit activates the smoke alarm siren.
CAUTIONThe control unit has been set and tested by RIVA.
Do not alter the programming controls, read the user manual for a correct operation reset, or better, address the RIVA After Sales & Service Department.
CAUTIONIn case the accumulator of the smoke detection unit is discharged, the siren starts automatically.
Use of the smoke control unit and of the signal light/ acoustic alarm unit

| Component | Maintenance | Notes and precautions |
| HFC227 gas fire extinguisher | Checks and tests | Check the charge status by means of the pressure gauge installed on the cylinder. The charge status can also be checked also by measuring the cylinder weight. The extinguisher is properly charged when the pressure and weight values comply with the specification reported on the extinguisher tag. Before installing, weigh the extinguisher (bracket excluded) and record the date and weight on the special tag. Check the weight (bracket excluded) every six months: if the weight has decreased with respect to the previous checks, recharge or replace the extinguisher. Have the preservation status of the container (cylinder) checked by qualified technicians at least at the beginning of each season. |
DANGERAccidental discharge of the fire extinguisher during handling or installation may cause serious injury. Insert the safety pin on the valve again until the installation or the check has been completed.
Protect your eyes during maintenance and installation operations.
DANGERDuring maintenance operations, pay attention not to unintentionally break the flask, because, even if the safety pin is inserted, if the flask breaks, the fire-fighting system activates.
DANGEROnce maintenance and installation have been completed, remove the safety pin from the extinguisher valve.
DANGERBefore entering the engine room, it is necessary to ventilate the rooms properly, so as to avoid risks of burns and poisoning, due to high temperatures and to noxious gases suspended in the air.
