C&K System 238 help required

[nizabd]

Hi all,

I will be obliged if someone could help.

I have existing hardwired door and windows with magnetic sensors in series connection with a bell as basic DIY system which has served me for number of years.

I would like to upgrade to C&K System 238. While bench testing I have not been able to configure the system program to operate as sensors in short circuit condition.

any suggestion.

Thanks.
