Elk M1 and loop4

[opticalc]

Looks like maybe the Elk only supports loops 1-3? (using both ElkRP and the KP you can only select up to 3)  I see some devices that do stuff such as tamper on loop4.  Is there any way for the Elk to look for signals on loop4?
 
I posted this same ? on the diy form some time ago. A few pros chimed in but looks like this may not be possible, Just posting here to cover my bases.
 
Thanks!

Should be a non issue if you use the supported detector models. Read the installation documents.
