Before discussing the custom legacy alarm solutions for the SiteBoss, we should touch on the standard I/O cards that the SiteBoss supports. These I/O cards come with 8 pairs of inputs that can be used for contact closures, analog voltage inputs, 4-20mA inputs, and relay outputs, depending on the card. These cards also have isolated and non-isolated input options. Currently, the SiteBoss has over 27 different I/O expansion cards, so the SiteBoss can be easily customized to have just the I/O needed. Since they are field swappable, the expansion cards also allow for the I/O to be expanded in the future without the need for a whole new SiteBoss unit.

The most common way to port over legacy alarms that are wired to an existing alarm block is to simply put a new alarm block by the existing one and punch over the alarms. This solution takes far less labor than having to rerun alarms or dismantling an existing alarm block.
