16 Channel Input/Output expansion card

To add more I/O capability to the extensive options already offered by the Syncro and Taktis control panels, up to thirty two, sixteen channel I/O boards may be connected. The 16 channel boards may be mixed on the RS485 bus with 8 way relay boards, 6 way sounder boards or 4 way conventional detection zone boards to provide a very flexible system of I/O to satisfy any requirement.

When using a simple two wire RS485 communications protocol, these boards may be mounted locally to the control panel or distributed on a bus up to 1200 metres long by using a suitable cable. The flexibility of these boards is further enhanced by the fact that each of the channels is configurable as either an input or and output.
