NOTES
:
1
. The R8, R9, C8 network provides a 2.7V Peak-to-Peak AC signal input to Pin 5.
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 operate with a remote
switch by adding an R-C network to
the occupancy sensor module. R
limits the current from the remote
module into Pin 11 of the LS6505
and C suppresses noise.
