The four wires to the motion sensor, 2
normally closed wires are not connected
to the DSC 1550 alarm system. The other
2 power wires are connected to the aux.
Power of the DSC 1550 alarm system.

  I just want to close off all the six
zones of the DSC 1550 alarm system with
a wire, if this option is safe, or with
a wire with the end of line resistor
attached. Just to make the DSC 1550
think that all is well. This will turn
all the lights off on the keypad.
