3/4.3.3.8 FIRE OCTICT!0N INSTRLHENTATION l Operability of the fire detection instrunentation ensures that adequate  :

warning capability is available for the prompt detection of fires. 1 This capability is required in order to detect and locate fires in their early stages. Prompt detection of fires will reduce the potential for damage to safety related equipment and is en integral element in the overall facility fire protection pro ~ gram.

in the sitent that a portion of the fire detection instrumentation is  !

inoperable. the establishment.of frequent fire patrols in the affected I areas is required to providt detection capability until the inoperable '

instrumentation Js restored ts OPERA 8!LITY. l l
