D2D Jumper Settings; Setting The Light Flash Polarity - Python Responder LC Model 991 Installation Manual

D2D Jumper settings

The security system has the ability to work with a compatible module through
the D2D lines. There are two settings: one for using an internal docking module,
(p/n XK 400N) or an external docking XK module.

Setting the light flash polarity
Light flash (+) / (-) polarity
The internal fuse is used to determine the light flash output. In the (+) position, the
onboard relay outputs (+)12V on the WHITE wire, H1/11. In the (-) position,
the on-board relay will supply a (-) output. When wiring into a multiplex circuit,
you can replace the fuse with a resistor (paying attention to the polarity setting).
(Refer to diagram on p.16, H1/4 White/ Brown wire description).
Note:
For parking light circuits that draw 10 amps or more, the internal jumper
must be switched to a (-) light flash output. P/N 8617 or a standard automotive
SPDT relay must be used on the H1/11 light flash output harness wire.
