Comfort Automation/ Security System Forums

I\'ve got a config where a CBUS switch is used to activate an output via a RLY01 unit (to a AV device).

 

It polls it for 0.5 seconds to power up the device. Been working fine for months, on OP4 to the RLY01

 

I\'ve now added a dedicated IRM01 to control the AV Amp (OP5). The script goes like this.

Pulse OP4 For 20

IR Code DB930TVIN To InfraredEmitter

 

Now, if I do this, it actually triggers OP4 twice. So it turns the device on then turns it off again. If i remove the IR line, the OP4 trigger works fine again as normal. I\'ve got a workaround to trigger the IR line via a timer - but we shouldnt have to do this.

 

OP4 and OP5 are not common plugged on the Comfort mobo, so whats causing this ?

Are you sure that OP4 is pulsing twice?
Can you put a Test lamp on OP4 and see if it turns on two times? Or put the RLY01 close to the OP4 - can you hear it clicking two times?
I dont believe the signal is coming from the OP4. It may be induced on the wires by the other signal. Are the two wires from OP4 and OP5 running close together?
