13. Connection to Ancillary boards
Ancillary boards connect via a 2 core cable to the terminals marked RS485 + and – on the HYDROSENSE HSCP
main control panel PCB. Up to 7 Ancillary boards may be connected and each board has terminals for the
incoming cables and outgoing cables. All except the last ancillary board, sounder board or repeater panel
connected to the cable must have the jumper links J2 removed.
Set the ancillary board address using the DIP switch (SW7); ensure no two ancillary boards share the same
address.
Apply power to main panel and all ancillary boards then briefly press the PROCESSOR RESET button on the
main panel, wait for a few seconds and the main panel will show the addresses of the ancillary boards that
were found on the display for instance o1 indicates that an ancillary board at address 1 has been found.
Press the ENTER button to accept each ancillary board that has been found.
The control panel will report a fault if any ancillary boards that have been accepted
become faulty or go off line.
For full details of commissioning procedures for ancillary boards see the HYDROSENSE HSCP Ancillary board
Operation and maintenance manual.
