Overview

The Sigma Ancillary Board is compatible with all Sigma CP and CP-R panels which have operating software version V2.0 or above.

The board provides common fire, common fault, coincidence and zonal fire, volt free contacts allowing control of sub-systems, graphical mimics and plant, remotely from the main panel over a two wire data bus.

Mains powered 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.

A mixture of Ancillary boards, Sounder boards or Repeaters up to a maximum of 7 of each type 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.
