Ness M1 motion detector for Cbus light trigger with Override

Looking for some help!

I am triggering Cbus GA from Cbus interface in M1 panel but need to provide an override button on local Cbus switch. Problem is that the motion detector senses movement and triggers GA with timer rule in M1 before you can trigger the override and therefore times out and turns off the GA even though override is on. The GA being triggered is a DALI light so no 'relay logic' can be utilised.

I really need to have a logic example that emulates the 'relay logic' that i would normally use for an override, only this would be used for a non relay GA ie DALI in this case.

Any ideas????

Put the logic in the M1. When it sees the override from the cbus side, don't issue the timer.

 

I use logic that says if the group is not on (and dark) then issue the timed on command.

For a dimmer ON is considered to be 1% or greater.

I use this not only on the PIR's but also on reed switches all through the house with the M1 and C-Bus controlling lights and fans.

 

Cheers Ashley, much appreciate the assistance

 

Thanks Mick, will give it a go mate.

 

Thank you both, problem is when the M1 timer has started and then the override is pressed the timer still runs and therefore turns off GA at timer end. There is no way to terminate a timer in M1... I think the timer and therefore logic needs to be in PAC so timer can be terminated once override is pressed...

 

Put the M1 timer on an unused output. Then have a rule that says when the output goes on, turn on the cbus ga. Have another rule that when the output goes off, only turn off the ga if the override is not on.

 

That's it!..Cheers Ashley works a treat. Cbus switch turns on/off actual GA of light plus an overide GA, M1 sensor turns on a dummy output for 5mins, that dummy output in turn turns on actual GA of light but when it turns off it first looks for overide GA to be OFF. Thanks again. Nath
