S14a Alarm + Hazzards Issue

I have a problem where my car hazards wont flash when I lock and unlock my car.
If you sit inside whilst locking it you can hear a relay in the center console click on and off twice and also when the alarm should be going of it clicks continuously.
I assume this is for the hazards tied into NATS.
The hazards work fine off of the switch in the car and the remote locking also works fine.
From what I have gathered my NATS fuse may have blown, does anyone know how and where it is located?

Cheers,
Sam
