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.
