the LCD and the optional Communication Board; terminals of RS-485 and CAN bus for the
communication between internal circuit boards.
IO Board
It generally contains terminals or interfaces for connecting the P.S.E, the internal B-Board, the
loop devices, the Loop SPU, the additional loop board (if applicable) and other peripheral
devices. The Loop SPU on it is to protect the loop from high energy voltage surges.
The diagram below shows the connection terminal blocks for field devices on the IO Board.

Communication Board
(optional)
This board is optional for external communication with other panels or FIPs (fire indicating
panel). Specifically, up to 20 panels can be networked with each other through the terminal
pair of CANH and CANL on the communication board; the FIP is connected to the terminal of
485A and 485B, that is, communicates with the control panel using the RS-485 protocol.
3.2 Mounting the chassis to the wall
The panel can be surface or semi-flush mounted through the four mounting holes provided
(the size of which is 6mm). See the diagram below about the mounting dimensions.

3.3 Mains connection
To connect the panel to the main power source, use a three-core cable with good quality
cable glands fitted, and connect it to the P.S.E through a PSE Filter with a 3A fuse as the figure
shows below.
