some help please with my 1st job some simple logic

Ive got a small system possibly with 3, 2adimmers 3 , 1a diimers 4 ,12way relay
and a bus cupler also a pac unit. Can someone tell me how to do this ive got a smoke detector output into the buscupler on term1 i would like to turn on some lighting circuits when the alarm is activated and when the alarm is de activated i would like the lights to go off (or to previous light levels).I have other Questions but i would like to sort this 1st.

 

Logic in Output Units

Hi,

You should be able to do exactly what you're after using Logic in your dimmers/relays, which will be far simpler than writing PAC code.

You just need to:
Assign a lighting group to the bus coupler input with the smoke detector.
Open your dimmer/relay UI's in toolkit, go to the logic tab, select the group you set the bus coupler too in the 'Logic Group' drop box, then apply Max (Or) logic to the channels you wish to go on when smoke is detected.
(Checkout the help file for more detail, there is an example called "Adding logic control to channel programming" which is very similar to what you're after)

The dimmer/relay channels will now go to the higher of their normal or logic group, so when the logic group is off they will operate normally, when logic group is on they will be on.

Cheers,
Mark.

 

Smoke Alarm to control Lights

{when the Smoke Alarm is in alarm condition, turn On some
lights}

once (GetLightingState("Smokey") = ON) then
begin
SetLightingState("SomeLights", ON);
end;

{when the Smoke Alarm is disarmed, turn OFF some
lights}

once (GetLightingState("Smokey") = OFF) then
begin
SetLightingState("SomeLights", OFF);
end;

The Bus Coupler would need to be set to "Bell Press"

 

For the sake of learning, do it both ways as mentioned. Using logic int he output units and then via the PAC.

Once you have both working, decide which is best for you and go that way.

Me personally, I would do it in the output units, very simple
