BF354 EN54-13 Sounder PCB
It is assumed this product will be installed by a technically competent person who is fully conversant with
the full Installation & Maintenance Manual for the CFP range of fire alarm panels.
Function
The EN54-13 Sounder PCB (shown right) provides two sounder circuits
for the CFP fire alarm panel that are fully compliant with EN54-13
(Compatibility Assessment of System Components).
Each sounder circuit has to be fitted with an Active end-of-line Device
(EOLD).
Items Supplied
1 x EN54-13 Sounder PCB (Part No. BF354) – shown right (above)
2 x Active EOLD (Part No. BF355) – shown right (below)
1 x 2-way polarised power supply loom
1 x 10K resistor
2 x retaining screws
Installation
Note the Sounder PCB has to be mounted inside the CFP enclosure.
Always remember to power down the system before fitting the Sounder PCB.
Step 1. Isolate Mains supply to the CFP panel and disconnect the panel’s battery back-up supply.
Step 2. Remove the Main Control PCB from the CFP panel (note that the connection cable needs to
be disconnected from PL1 on the Power Supply PCB). See Fig.1.
Step 3. Locate the two mounting slots provided in the base of the CFP panel, then slide the Sounder
PCB downwards into position and secure with two retaining screws (provided). See Fig.1.
Step 4. Wire the 2-way polarised loom (supplied) from PL1 on the Sounder PCB to PL2 on the
Power Supply PCB. See Fig. 1.

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.

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.
