Prevent PIR turning Lights off

I have inherited a job where there is some 240v PIR's wired to a aux input unit. the inputs are set to bell press and when the GA goes on it triggers a Scene in the PAC to turn on 4 outside lights. it then turns it off when the GA turns off.
They also have individual control of each of the 4 GA's on some DLT's. problem is when they turn the lights on maunually the PIR turns them off after movement.
i have tried the following in PICED but it doesn't work if the lights are turned on during the Bell press. There is a GA in the Scene that is used to track wheter it has been turned on.

once (GetLightingState("pir rear") = ON) and
(GetLightingState("#hexled6") = OFF) and
(GetLightingState("#outside right side entry") = OFF) and
(GetLightingState("#outsidepillarrearclr") = OFF) and
(GetLightingState("#outsidewalkwayleft") = OFF) then
begin
SetScene("PIR Rear On");
end;
once (GetLightingState("pir rear") = OFF) and
(GetLightingLevel("REARPIRTrack") = 100%) then
begin
SetScene("PIR Rear Off");
end;

Can anybody suggest another way to do this? Thanks

 

I do this......

{Auto light on, if not on by switch}
once GetLightingState("C4K Pantry")then
if (GetLightingLevel("Pantry Downlights") < 99%) then
begin
SetLightingLevel("Pantry Downlights", 98%, "0s");
end;

{auto light off, if not on by switch to 100%}
if (ConditionStaysTrue(GetLightingState("C4K Pantry") = OFF, "0:00:10"))
and (GetLightingLevel("Pantry Downlights") < 99%) then

begin
SetLightingLevel("Pantry Downlights", 0%, "15s");
end;

{auto light off after 10 mins, if on by switch to 100%}
if ConditionStaysTrue(GetLightingState("C4K Pantry") = OFF, "0:10:00") then

begin
SetLightingLevel("Pantry Downlights", 0%, "30s");
end;



The "C4K" is from my alarm PIR and turns light on to 98%, if no movement for 10 seconds light goes off. This is "over-ridden" when the light switch is used to turn it on to 100%, it then has a 10 min no movement time (or you may wish to have no off time).

Hope this is of some help.
