14. Option Parameters – Required if Using
Options
14.1 Introduction
Every 1ZC controller supports RS-485 serial communications. The 16C, 18C, and 25C
models can support a variety of options, including serial communications. The available
options are described briefly below. Use of most of these options requires that you
configure a few parameters. These parameters are arranged in menus, one for each
option.
However, the menu for a specific option is not displayed unless the CardCard parameter in
the OptnOptn (option) menu has been used to specify correctly the type of options supported.
The OptnOptn (option) menu CardCard parameter is configured at the factory. However, if you
use the procedure in 12.5 to load all parameter defaults, then you must use the front
panel of the controller to configure the CardCard parameter in the OptnOptn (option) menu. This
prepares the controller to receive the appropriate option parameter values. The only
exception is in the case of an 18C or 25C equipped with only the serial communication
option. The 18C and 25C models are always ready to receive serial communication
parameter values.
The options menus are available if the security access level is set to CnF9CnF9
(configuration) or FACtFACt (factory).

14.2 Options Supported
Every 1ZC controller supports RS-485 serial communications. Two communication
protocols are supported, MODBUS and Athena Plus protocol, each with its own firmware
on the processor board and its own configuration menu (see 14.5 and 14.6). The 16C,
18C, and 25C can also all be equipped with optional RS-232 or RS-485 serial
communications hardware, and the appropriate communication firmware for Athena Plus
protocol (RS-232 and RS-485) or MODBUS (RS-485 only).
Other options are also available for the 16C, 18C, and 25C.
• Two alarm outputs are available; the action of these outputs follows the action of
the A1 and A2 front panel LEDs and are configured using the ALrALr menu (see
Section 9).

The access level in all new 16C, 18C, and 25C controllers is set to CnF9CnF9 at the factory. If you cannot
see the option menus, the access level has been changed to a more restrictive level. Instructions for
changing the access level are in Section 17.
