Comfort Automation/ Security System Forums

I am currently building my first Comfort system. What size standoffs do I need to buy to stack the LEM03-M2 and UCM/ETH2 on top of the CM9000-ULT?

You need to use M3 standoffs which are stackablem ie have threaded holes on top and screw threads on the bottom
So if you stack one on top of another, you need 8 sets
But I think there may be a height problem, you may not be able to close the box
Why not mount one on the bottom and stack only 1 PCB?

I am using the smaller EN01 enclosure, which in addition to Comfort, needs to fit two Visonic wireless receivers. I would like these inside the enclosure so I don\'t need to install EOL resistors.

Stacking three PCBs will be tight, but it looks like it should just about fit.

Thank you for your help. I have ordered some M3 standoffs.

make sure the Visonic receivers have their antenna outside the metal box otherwise they will not receive any RF signals
