LST700 SERIES FIRE ALARM PANEL
Certain fire alarm panel functions can be temporarily disabled (i.e. switched off) to suit prevailing
conditions. For
example, if there is a risk of a false alarm in a zone, say from vehicle exhaust
smoke
in a loading bay, it is possible for the user to disable that zone during the risk period and enable it
again afterwards.
Another example is the disablement of outputs during a routine test or temporary
fault.
Following is a list of options that may be disabled by the user at the fire alarm panel and the effect
their disablement will have on how the system works:-
