LPCB APPROVED CFP ALARMSENSE 2/4/8 ZONE FIRE ALARM PANEL
Installing the Main Control PCB
The panel's Main Control PCB provides all the 5mm connector blocks for the system's zone circuits, conventional
sounder circuits, auxiliary inputs and auxiliary 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 10 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.
Take care when reconnecting the 5mm connector blocks that you do so the correct way round. We recommend
that you clearly label all system wiring to reduce the likelihood of incorrect connection.
