SET is switched out (channel 1 sensor inputs become open circuits) and SET 2
(3H, 3L, 4H, 4L) are connected to the four COM terminals. A given SET will
typically be connected to the common terminals for 20 ms.
With panel switch set to “2x32” mode, the w
SETs are labeled beginning with 1H, 1L and ending with 32H, 32L. In “2x32”
mode when the AM16/32B selects a given channel, the “H” sensor terminal is
relay connected to both COM “H” terminals and the “L” sensor terminal is
connected to both COM “L” terminals (COM ODD H connects to COM EVEN
H and COM ODD L connects to COM EVEN L when panel switch is in
“2x32” mode).
