thanks! what sort of problems could i encounter if there is too much draw?

I need to connect three smoke detectors to my existing Texecom 48 system. I don't want to run cables back to the panel, so I planned to connect the detectors to an expander, which would be connected to the spare cable sitting in the loft which was already taken back to the panel when the system was installed. I want to avoid using a power supply with the expander if possible. I do not have any other expanders on the system currently. About 14 zones on the Texecom 48 are used. What are the options, and would I be better off running three separate cables from th epanel to the loft? It will be a pain in the a*se mind.
