I am using the xbee pro 900hp mesh kit, and using for remote building monitoring

i need a simple network, i have 3 buildings, 1- would be the receiver for the other 2 Xbees, relay contacts close on fault, transmit back to building one. this Xbee is receiver and will provide o/p to cellular modem.
i have setup 2 xbee,s i can see they are communicating. but i cannot get o/ps triggering.
i have same CM,ID,DH- is destination Xbee.
API mode 1
D4 is set to input on trans, set to output on receiver.
RP-5
IC-30
IR-64

customer asked to use this kit, he has no experience. and neither do I.
reading User guide tonite,again

thanks for any help

I am not sure what you need help with. If properly configured, when a status changes on the input module, an API frame should be sent out the receiver.
