Activ8 AM-DT 8IR140

[oldguy]

Just bought one off ebay...cheap to fit in in laws conservatory (as standard PIR keeps false alarming),

I have the 8IR110's in my own house and have no problems with these in my conservatory - that's what I understand about the DT's as they need both signals to alarm, hence why I got the 8IR140....

Not got home to check yet but I was sure the 110's have just one connection for the NC zone connection covering the PIR and microwave?

This appears to have 2 connections for the PIR but then there's the other 2 for the antimask connection?

So I need 8 core wire, and there's only 6 into the conservatory.

This would put the sensor over two zones?

I don't really understand but I guess these are 4 connections - 2 for the PIR, 2 for the microwave (effectively?)

any help appreciated

thanks

EDIT...bit more googling!

Understand the anti-mask now I think......(clue is in the words), so I can just not bother with the anti-mask connections, the dual tech is covered under the PIR NC connection to the zone?

EDIT 2....search function...understand it now

You don't need the antimask

don't need it, also depends on what panel its being put on as to what you can do with limited cables.(resistors).
