Ancillary PCB

The LIFECO Ancillary Board is compatible with LIFECO HAWK Releasing control panel. 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. Ancillary boards require only a two core data cable from the main control panel and a two core power cable from the main panel. 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 4000 feet. 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.
