Bastiaan obtained a smoke detector to conform to rental requirements, but we might be able to make more out of it.
The device is little more than a logic board hooking up some simple input and output to a single chip: a BL59S10. Description is found here: externally and mirrored locally
The interesting pin is 7: I/O. Although there are no specific details the description mentions that "It can be used to connect up to 40 detectors to make auxiliary alarm, remote alarm, auto dialer..."
