2. The C7, D1, Z1, C6, R6 components generate the DC Supply Voltage for the LS6505.
3. The R1, C1, R2, C2, R3, C3, R4, C4, R5, C5 components and the two on-chip Differential Amplifiers set a
nominal gain of 5,500 with bandpass filtering of 0.13Hz to 6Hz.

When operated in Mode B or Mode C,
the wall switch occupancy sensor shown
in Figure 3 can easily be adapted to op-
erate with a remote switch by adding an
R-C network to the occupancy sensor
module. R limits the current from the re-
mote module into Pin 11 of the LS6505
and C suppresses noise.
