Overwrite a lock

[eulaersivan]

I have a presence detector #1 (Merten Argus 220 new model) which should only be working when a binary input value is equal to 1 (the binary input value is an indicator if the home alarm is on or off). I have a secondary detector #2 (Merten Argus 220 old model) that should overwrite the binary input value.

In other words ... when the home alarm is on (binary input value = 1), the presence detector #1 should be working and detecting any presence. When the presence detector #2 detects any presence, the presence detector #1 should NOT be working (even if the home alarm is on) for 30 minutes.

I was thinking of using the lock object of presence detector #1 to accomplish this, but I'm stuck.

Can you recommend how I can set this? If necessary I can also use an eibpc to accomplish this, but I would prefer to accomplish this without eibpc.

Hi Ivan,
I suppose that you intend to use just one group address for armed signal, activated sensor #2 and lock function of sensor #1 when you are talking about "overwriting" the lock function. This will not work as the last occurred signal will always overwrite the lock function.

You will need a AND logic with two inputs:
1) the "armed" signal of your home alarm and
2) the active indicator of sensor #2
Output would be then the lock function of sensor #1.

Now you have to take care of the polarity of the signals.

Home alarm armed = 1
Sensor #2 not active = 1
AND output = 1 -> unlock sensor #1

I haven't tested it but it should work.

Cheers

Tx for your reply. I'll create the logical functions in eibpc.
