When using the pressure switch as a electrical disconnect for any equipment shutdown function,
a means of overriding (bypassing, shunting) the pressure switch must be provided in order to
return the affected equipment to an operational mode after extinguisher discharge has occurred.
The pressure switch is a single pole single throw (SPST) type that is normally closed (NC) with
the system in the charged condition. Discharge or loss of system pressure will release the
contacts to an open state thereby cutting off any electrical current flow.
NEVER USE PRESSURE SWITCH FOR ELECTRICAL LOADS OVER RATED CAPACITY.
SWITCH SPECIFICATIONS
4.0 AMPS AT 12 VDC
2.0 AMPS AT 28 VDC
For applications requiring larger load capacities, see optional equipment section in this manual or
contact factory.
ENGINES AND POWERED VENTILATION (BLOWERS)
DIESEL ENGINES
Continued operation of diesel engine(s) and or powered ventilation units will deplete the
extinguishing agent and may cause a fire re-flash. Diesel engine(s) must be automatically
shutdown upon extinguisher discharge.
Note: Power ventilation (blowers) that exceeds one air change per minute within the protected
compartment must be automatically shutdown upon extinguisher discharge.*
* ABYC Requirement- Standard A-4
GASOLINE ENGINES
Shutdown may be accomplished by interruption of the electrical circuit between the ignition switch
and the engine coils.
NOTE: Sea-Fire optional engine interrupt systems will automatically shutdown engines and
powered ventilation upon discharge of the fire suppression system. They are available in 12 and
24-volt models with 3, 5 or 8 control circuits. Refer to optional equipment section in this manual.
REMINDER: Sea-Fire 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.
