thanks

Whatever the Sensor output wire is that goes to the alarm, you would cut that line or I like to say, Interupt that line with a relay. So one side of the cut wire goes to 30 and the other side goes to 87a. The coil of the relay would then be controled by whatever constant output your going to use trigger the bypass. If it's a negative output, then that will go to 85 and 86 connects to +12v, or if positive output, that goes to 85 and 86 would connect to GND.

so what ur saying is i don't need a relay with a diode on it! just a regular relay!

Well, you could put a diode across the coil if you wish too, but as far as using it to isolate the sensor, I don't see the need in this circumstance. Think of a diode as a one-way street. It only allows current to flow in one direction.
