The DIO is a custom module containing two Class B inputs and two Class B / relay outputs. It con-
nects to a Classic 2000 Mk II's RS-485 network, and runs off an external 24VDC power source.
The two inputs provide a two-wire initiating circuit for normally-open fire alarm and supervisory
devices. The two outputs allow the host panel to switch discrete contacts on command, using one
of two switching modes. The outputs, by default, are configured to switch external DC power or
audio power (selected by removing on-board jumpers) provide one set of Form-C (SPDT) relay
contacts per output. In this mode, the outputs are not supervised.

The PNI provides a way for a Classic 2000 Mk II FACP to communicate with Sigma Mk II FACPs,
use Sigma Mk II input zones as addressable points, silence and reset a Sigma Mk II from the front
panel of a Classic 2000 Mk II, and view the status of the Sigma Mk II over an RS-232 cable. The
Sigma Mk II must have an ZSCP1 installed. The ZSCP1 provides the RS-232 interface to the PNI,
as well as a local RS-485 network, which can be used for adding ZFZA, ZTZB, or ZRAN devices.
Power comes to the device through one of the Sigma Mk II's 24VDC outputs. The PNI provides iso-
lation between the Classic 2000 Mk II network and the Sigma Mk II, preventing ground fault trou-
bles on both panels. Using the PNI, the Classic 2000 Mk II can silence and reset the Sigma Mk II
panel, but is not able to control the Sigma Mk II NAC or relay outputs. Standard configuration is
one PNI board per Sigma Mk II. The PNI is suitable for mounting in snap-track.

The ZRPC (Zeta Remote Power Converter) module will allow the addition of up to two ZACMs
mounted remotely in a Zeta Serial Device Enclosure (ZSDE), see Section 6.7 and ZRPC installa-
tion instructions for more information. Each ZACM provides for two Style 4, 6, or 7 SLC loops.
The ZRPC provides the network and power connection and mounts in the ZSDE. (See the installa-
tion instructions included with the ZRPC and ZACM.)

The ZRLD (Zeta Remote LED driver Annunciator) is a serial device with the following capabilities:
Displays the status of up to 60 points or groups.
Sounder mimics the operation of the Classic 2000 Mk II main panel buzzer.
Ability to reset the system from the ZRLD keyswitch.
Ability to silence the ZRLD, as well as all devices on the system, from the keyswitch.
Each Classic 2000 Mk II will support up to 16 ZRLDs (subject to power available). Each ZRLD
features a DIP switch to program the ZRLD network address and options.
Ability to program 30 Groups on the ZRLD (1-30), and 30 more on the ZRLD-EX (31-60).
The Classic 2000 Mk II FACP can drive remote LEDs for system status annunication, or for build-
ing mapping applications. Remote LEDs can be driven by up to sixteen ZRLDs (each of which can
handle up to 60 LEDs).
