Walkera RX802 Receiver Failsafe

I am using a Walkera RX802 receiver.

Does anyone know if it is compatible with the Devo 8S Deviation failsafe?

i.e. when the signal is lost or the transmitter is turned off, it will automatically activate the failsafe on the Naza Lite flight controller?

How do I activate it, at Bind time?

If not, is there any type of failsafe unit I can add to my system, between the receiver and the U channel on the Naza maybe?

Thanks.
