8.1.6 OPERATING SEQUENCE - SPECIFIC POINT DETECTOR DIRTY LEVEL
To recall a specific point's % Dirty level press:
where rrr is the responder number
ppp is the analogue point number
The FIP will access its internal database for the required information for the point and display
the % Dirty level.
The LCD briefly shows an asterisk, "*", in the top right of the display whenever data for the %
Dirty display is updated.
% Dirty information is displayed only for MPR smoke detector points. For all other points
there is no % Dirty level, thus the F4000 displays “No Recall Information Available”.
