One of the issues I have with my installation is terminating all the +12V & gnd connections that feed to the detectors. I have about 12 pairs of cable all attempting to go into one screw down/push on connector. This is obviously not possible so I have extended the 12V output by daisy-chaining a series of screw terminal 'chop-block' connectors. This works but is not something I am NOT very proud of + I feel it is not reliable, I'd be interested to learn what others have done to deal with this issue
Cytech - please could you let me know the make and type of the push on terminals - the one's in the attached image.
