Passenger
ships must have an automatic sprinkler and alarm system in all control
stations, accommodation and service spaces, including corridors and stairways.
Spaces having little or no risk need not be fitted with an automatic sprinkler
system. [CO2 room, toilets etc.].
A
number of sprinkler heads are supplied with water under pressure, the system
being initially charged with fresh water to avoid corrosion. The system should
provide a minimum water flow of 5 l/m2/min
and the heads should provide complete cover. The pressure tank should provide one-minute supply without the pump and
have a volume of at least twice this amount. The pump should be dedicated to the sprinkler system only.
A
visual and audible alarm should be given automatically indicating which section
is affected; each section must have means of testing the alarm. A pump running
alarm is normally fitted.
The
system is provided with a shore connection and is connected to the fire main by
a lockable S.D.N.R. valve, normally closed. System pressures 5.5 to 8.5 bar.
A manual system
replaces the section valves with remote / manual operated valves and the pipes
between this valve and the sprinklers are empty. Operation is by opening the
required valve. There must be a separate fire detection system, which can be
arranged on a ‘double knock’ operation so that two fire detector heads in alarm
in any section will automatically open the required valve

A fire water pump is a critical component of a building's fire protection system. It is designed to provide water flow and pressure to sprinkler systems, hydrants, and other firefighting equipment in the event of a fire. Visit Fire Pump Room Installation
