AUXILIARY EQUIPMENT AND SYSTEMS

A sub-system of components is used to provide auxiliary interlocks that occur at system

actuation. Such interlocks may include electrical connections, such as fan or process shutdown,

and/or mechanical operations, such as door or vent closure.

Where the continuing operation of equipment associated with a hazard being protected could

contribute to sustaining the fire in that hazard, the source of power or fuel shall be

automatically shut off.

NOTE This does not apply to lubricating oil systems associated with large rotating equipment,

where an extended discharge system is provided and that is designed to operate for the

deceleration/cooldown period.

All shutdown devices shall be considered integral parts of the system and shall function with

the system operation.
