System requirements:

  • The verification of the operation of the fire alarm (by simulation) must be carried out before departure, during training and at least once every 10 days:
  • When checking the operation of thermal signalling devices, they are warmed by directing a hot air current at the required temperature. It is forbidden to heat them with open fire.
  • Smoke alarms shall be checked by approaching them at a distance of 50 to 100 mm by means of a special device with a smoking agent.
  • If alarms need to be removed to check or repair a ship's fire alarm, new alarms must be installed in their locations immediately.
  • The results of the inspection of the fire alarm unit operation shall be recorded in the inspection logbook.
  • Once every four years, fire alarms must be inspected at technical maintenance bases to determine their compliance with technical requirements.
  • The warning signal for the release of vapour and fire-extinguishing gases into a room where there may be human beings shall be checked together with preventive checks on these systems, but at least once a month.

 

Testing systems

The manufacturer recommends that all sensors be tested at any time of the year. Fire alarm sound horns automatic door closure and ventilation braking must be switched off before testing. The verification of the system may be carried out only by a specialist who is qualified and familiar with the fire alarm system being tested.
Heat sensors are checked with special heat testing equipment recommended by the manufacturer. Attach it to the sensor in a marked place and hold it until a red tell-tale lights up on the sensor.
NOTE: The sensor should not be overheated when using other testing equipment. Excessive heat can damage the sensor, melt its body.
Check smoke sensors with special testing equipment recommended by the manufacturer. To this end, smoke is sprayed into the sensor for 1 second from a special capacity, repeating it every 10 seconds until a red tell-tale lights up on the sensor. When using other testing equipment, you need to make sure that the sensor is not damaged.
Fire sensors can be checked with a lighter. To this end, keep the ignited lighter at a height of about 5 cm in front of the sensor, at a distance of 5 to 2 meters and slowly moving it during testing until a red light is lit on the sensor.
