AC/DC Input with Transformer
Sharing
Modules with this feature can share a
central transformer (16-24Vac, or 16-
36Vdc) throughout the system. Ensure
that the total power output of the
transformer is respected. There is no
specific polarity.

RS485 Access Bus
Connect to V32 RS485 Access bus.
Ensure that it is powered by an
external power supply (PS27D). This
will not be necessary with an
upcoming V32 hardware version,
which will supply the power (see
www.paradox.com for availability).
5
Battery Input
Connect a 12Vdc (4Ah or 7Ah)
rechargeable gel cell battery. Apply
AC power before connecting the
battery. If battery wires are extended,
use an external fuse to protect against
a short.
