PCB Layout
Monitored Inputs
The panel features two monitored inputs that can be programmed either as latching or non-latching. It is impor-
tant to note that before using these inputs they must be enabled by programming them in the panel options
menu. If the inputs are enabled then 4K7 end of line resistors must be  tted at the termination. Applying a 470
resistor across the inputs will produce a ‘Fire’ message. The inputs are labelled ‘INPUTS’ and ‘No1’ and ‘No2’. These
inputs can be assigned a zone and text location, and then cause and e ects can be programmed for them. See
6.15 – Input Options for further information.
RS-485 Connections
The RS485 connectors are used for wiring hardware to the panel such as extra antennas or a secondary display. A
suitable data cable should be used with 2 sets of twisted pairs. Cat 5/5e/6 can be used but is not  re rated. Wired
antennas and displays have two RS485 connectors, making it possible to make a chain of up to 4 units. On the last
unit in any chain, a 100R resistor should be  tted across the D- and D+ terminals of the unused RS485 connection.
If one of the control/booster panel RS485 ports is unused then a 100R should be  tted between D- and D+. If none
of the panel RS485 ports are used then there is no need to  t the 100R resistor. The RS485 ports are capable of sup-
plying 500mA at 15V.
The use of this facility is not permitted for an EN54-2 compliant system.
