Alarm function expects a normally open relay, closing on
alarm. The diagram shows TOC-10 modules interfaced using
the link function, refer to TOC-10 manual for full details
Note for TOC-10 up to 8 detectors can be connected using the link function so if one
goes into alarm, all linked detectors go into alarm. In this example one TOC-10 of the
linked group has its alarm 2 relay interfaced to the TOC-630.
