Notes :-
1. T
hist
is shown on the analogue value
graph (see section 9.3).
2. Fire levels are calculated by
algorithms within the system (see
section 9.3). These fire levels change
with the device sensitivity.
3. Each channel of a multi-channel
device such as the Optical heat has
the same sensitivity.
