Motion sensor alarm with manual override

Motion sensor alarm with manual override I have a small shop with a carport off the back. I am installing a custom (okay hillbilly) motion sensor alarm system, to protect the carport area. I have installed a motion sensor (RAB STL-110) that feeds a mechanical timer (so I can set when the motion sensor is active). Down stream of this timer I installed a flashing red light with an alarm (to startle the ne’er do wells) and an LED light facing my house (I can see this light from my living room as a visual indicator that the motion sensor has activated). Everything has gone well up to this point and all the components work. I now want to add a manual switch on the exterior of the shop, so that if I want to access my carport, I can hit this switch and interrupt the power that feeds the red light/alarm. Then, when I’m done… I hit the switch and re-energize power to the red light/alarm (this helps avoid false triggers….and mad neighbors). If it was just a switch….I could do that. But…. I also want this switch to send power to another light when I turn it off (SPDT?). This other light is a “reminder” light. It would stay lit until I flipped the switch back to the red light/alarm. That way I don’t accidently leave the motion sensor alarm system de-energized. Switch in position #1 energizes the red/light alarm and interrupts power to the “reminder” light. Switch in position #2 interrupts power to the red light/alarm and sends power to the “reminder” light The other criteria is that the motion sensor can not lose power (when it re-energizes it defaults to “test mode”) Can someone provide a sketch/wiring diagram for how I get this accomplished? I now have a SPDT switch and I also have a 120-volt relay (OONO Mod # F-1056) I’ve done basic wiring (I did the lights and outlets in the shop), but I’ve never wired a SPDT nor a relay (if the relay is even needed).
