Step 5.
Wire the conventional sounder circuit(s) to the Sounder PCB terminals (Sounder Out Circuit
1 & Sounder Out Circuit 2). See Fig. 2.
Step 6.
Wire the Active EOLD (supplied) to the last sounder on each circuit, as shown in Fig. 2
below. Note if sounder circuits are not connected, the Active EOLD must still be fitted at the
Sounder PCB terminals.

Step 7.
Terminate the sounder circuit’s screens at the panel’s base earth post. See Fig. 3.
Fig. 3 – Earthing Screens to Base Earth Post
Step 8.
Wire the Sounder PCB to the Main Control PCB and fit 10K resistor (supplied). See Fig 4.
Fig. 4 – Sounder PCB to Main Control PCB Connections
Step 9.
Refit the Main Control PCB in the CFP panel.
Step 10.
Reconnect Mains and battery supply to the CFP panel.
Step 11.
Test the sounder circuits for correct operation.
