Pressure Relief Assembly (Burst Disk)
All models are protected from over pressure of system. FG Models 25 – 240 and FD
150 – 1000 are protected by the design of the glass bulb temperature / pressure
relationship. Sea-Fire Marine maintains a Department of Transportation (DOT) Special
Permit, DOT-SP-11598 for these models.
FD Models 1025 – 1500 have a definite purpose Pressure Relief Device (designed and
manufactured per CGA S.1-1) installed on the manifold. Do not remove or perform any
maintenance on this device. Removing or loosening this device will cause the contents
under pressure to escape.
Interaction with Engines, Generators and Powered Ventilation (Blowers)
Sea-Fire offers optional engine interrupt systems which will automatically shut down
engines, generators and powered ventilation upon discharge of the fire suppression
system. They are available with 4, 6 or 8 control circuits and operate between 9 – 32
VDC. Shutdown may be accomplished by interruption of the electrical circuit between
the ignition switch and the engine coils.
It is the responsibility of the system designer /installer to comply with the following
instructions on Diesel and Gasoline Engines / generators.
Diesel Engines or Generators, Powered Ventilation (Blowers)
USCG, and American Boat and Yacht Council (ABYC) – Standard A-4, Fire Fighting
Equipment (Section A-4.7.3.3) both require the following:
The system shall be designed and installed so that the engine(s),
generator(s), and blower(s) located in the protected space shut down
automatically and after discharge the minimum required design
concentration must remain.
Gasoline Engines or Generators
It is optional to automatically shut down gasoline engines and generators, but it is
highly recommended. In the case of engine compartment fire, you must still manually
shut down engine(s) or generator(s) before manual discharge, or immediately after
automatic discharge of the fire suppression system.
Relationship to Portable Fire Extinguishers
Reminder: Sea-Fire pre-engineered systems shall be considered as supplementary to
the number of portable fire extinguishers required on-board and are designed and
intended for enclosed unoccupied compartment installations that are not subject to
direct weather or water.
