DETECTOR CIRCUITS
Installing the Main Control PCB
The panel’s Main Control PCB provides all the connections for the system’s detector circuits,
sounder circuits, auxiliary inputs and auxilary outputs. It also provides the engineer with access
to a wide range of engineering functions, details of which appear later in this manual.
Before any connections can be made, the Main Control PCB must first be securely positioned
inside the fire alarm panel (see Figure 11 below) using the five retaining screws. As the PCB is
presented to the panel, remember to attach the telecoms-style connecting cable to SKT2 on the
reverse of the Main Control PCB and to PL1 on the Power Supply PCB.
Important:
SKT1 on the reverse of the Main Control PCB is for the connection of optional
system expansion devices such as Network Driver Cards (for repeater panels) and Relay Output
Boards. If any of these devices are to be used, refer to the individual installation instructions
supplied with them as they will need to be fitted to the panel before the Main Control PCB.
All of the 5mm connector blocks located across the top of the PCB can be removed to aid
installation. Take care when reconnecting them that you do so the correct way round. We
recommend that you clearly label all system wiring to reduce the likelihood of incorrect
connection.
