Ancillary PCB

  • The Sigma XT Ancillary Board is compatible with all Sigma XT control panels which have operating software version SIGXT_11A. HEX or above.
  • The board provides volt free normally open contacts allowing control of sub-systems and plant remotely from the main panel over a two wire data bus.
  • Mains powered, boxed Ancillary boards require only a two core data cable from the main control panel. 24V DC versions require an additional two cores for power either from the main panel or from another 24V DC source.
  • Up to 7 Ancillary boards can be connected to a control panel and each is allocated an address from 1 to 7 using a binary coded DIL switch. The total length of the data cable from the main panel to the last repeater must not exceed 1200 metres.
  • A mixture of status units and Ancillary boards, up to a maximum of 7 of each type, can be connected to the serial data bus.
