Panel 2 is mounted in the same automation closet as the main panel. on left side of the panel DIN mounted terminal blocks are installed for the internal speaker wiring and the siren wiring. This made establishing series/parallel wiring to keep the speaker resistance in spec relatively easy and neat. A single output expander, number 7, occupies the right side of the cabinet and is fed from the DIN mounted connection blocks below it. The blocks are numbered with the zone number. Power for this panel is supplied from Panel 3. It is lighted by LED lighting mounted in the top of the panel.
