ZP3 Fire Alarm Control Panel Installation Manual
Built-in communication port
RS-232 built-in serial port
The built-in RS-232 port is used to connect the panel to an external computer for
the purpose of uploading or downloading the panel’s configuration program.
Configuration programming is normally done on a PC using Planner (the Planner
for Windows programme) and then loaded into the panel at the site via a portable
PC.
Note:
The preferred baud rate settings when using Planner to configure the
control panel are shown in Table 3 below.

Alternatively you can set Z-Port 1 to ZCP3 to allow control directly from Planner.
The protocol is RS-232, with a three-wire connection as shown in Figure 9. This
port shares internal lines with Z-Port 1a, and consequently the D-plug connection
to the ZP3AB-RS232 board must be physically disconnected before using the
built-in port.
