by the high input impedance op amp of a MAX951
(Figure 6). The comparator and resistor voltage divider
set an alarm threshold to indicate a fire.
Design and fabrication of the connection from the inter-
mediate plate of the ionization chamber to the nonin-
verting input of the op amp is critical, since the
impedance of this node must be well above 50M
. This
connection must be as short and direct as possible to
prevent charge leakage and 60Hz interference. Where
possible, the grounded outer electrode or chassis of
the ionization chamber should shield this connection to
reduce 60Hz interference. Pay special attention to
board cleaning, to prevent leakage due to ionic com-
pounds such as chlorides, flux, and other contaminants
from the manufacturing process. Where applicable, a
coating of high-purity wax may be used to insulate this
connection and prevent leakage due to surface mois-
ture or an accumulation of dirt.
