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.

Thanks, Joe

You have to jumper out the zones on the 1550 if you're not using them.
If you turn on light #5 in option 12, you can use regular 22AWG wire
between the "zone" and "zone common" terminals otherwise you'll have to
use the 1K ohm resistors. Program all the zones as "perimeter" (03).
It's been quite a while since I worked with a 1550 panel. Good luck!!

Thanks,
I will turn on light 5 in option 12,
and I will just put a wire from the
common to each of the terminals 1-6. I
wasn't sure if I still needed a end of
line resistor with this option.
I had all ready programed in option 11 (1,3)
Thanks Again, Joe

Hmmmm....why bother having a keypad if he's not using any of the zones on
the DSC for detection but merely for powering the pirs?
What panel in existence doesn't have power to run a few pirs, that he has to
use a different panel as a power supplyWhat's powering the cellular?

...whole thing sounds goofy.

I'm surprised at you Crash. I'm pretty sure the OP didn't purchase the
equipment from Bass (aka "Goofy"). Although I can almost hear the
"bAssification"... "DSC isn't really the best choice for a burglar
alarm, but they do make for a good power supply". ;-)
