Any idea where to purchase the 2 resistors (2.2k ohm) from required or do they come with the expander module thanks.

It's already got connections for 2 wired zones without the expander module. Just don't know where the resistor goes.

Anybody know how to hardwire an external sounder to a powermax complete panel. There is 4 hard wired connections. I'm using a Texecom Odyssey X-B (E) and I have a 2.2k ohm resistor which I need to use but not sure where.
