The Sigma CP-R Repeater is compatible with all Sigma CP control panels which have operating software version V2.0 or above. Repeaters are available with 2, 4 or 8 zones and in mains powered (K versions) or 24V powered (E versions). Mains powered repeaters 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 Repeaters, Ancillary boards or Sounder Boards 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.
