....... I am using several eagle eye sensors with the DS-7000 consol. Try un hooking the wires from the DS-10A door/window magnetic reed switch and hooking them up to a set of normally closed contacts on a relay or other n/c device and use the DS-10A as an interface.
I think what your saying is: Hack the EagleEye so instead of the sensor sending a RF signal.... it would close the contacts on a (magnetic reed switch removed) DS10A - door window sensor.
That would be quite a hack. Do you have a link to some instructions?
Wouldn't it be much simpler for the average guy to just let the EagleEye sensor send it's RF signal which could then trigger a Universal Module (UM506) which could trigger [open] the (magnetic reed switch removed) DS10A - door window sensor.
