19. System Overview
If you’re unfamiliar with installing a Classic 2000 Mk II system, please read through the following general
summary of the components, devices, and capabilities of a Classic 2000 Mk II system.
19.1 Description
The Classic 2000 Mk II analog addressable control is the most intelligent fire alarm control system ever
distributed by Zeta Alarm Systems. The Classic 2000 Mk II utilizes an advanced digital communication
technology to provide the installer and the end user with the most versatile, easy to use life safety system
available.
This new digital communication protocol allows the analog addressable loops to be wired with ordinary,
parallel fire alarm rated wire (under most conditions). You do not need to run twisted, shielded pair or any
other type of specialized cable.
The "analog" devices allow for the adjustment of the smoke sensor's alarm thresholds within the limits
defined by Underwriters Laboratories. Analog thermal sensors can be programmed with a temperature
threshold from 135° F to 194°. It also provides programmable daytime and nighttime sensitivity settings for
each sensor. These capabilities reduce false alarms and allow for more effective protection. Sensitivity and
maintenance condition of the sensors may be viewed from the panel display. Drift compensation and service
alerts make maintenance simple.
The "addressable" feature provides detailed status and custom 40-character identifying labels for each
initiating device and control module on the system LCD.
The local programming display features a 4x20 backlit LCD and ergonomically designed keypad for panel-
front programming and editing of all features. The optional PC3K programming software is recommended for
PC or laptop computer programming.
The Classic 2000 Mk II has two digital SLC circuits on-board and modules can be added to expand the panel
to a total of 12 SLC circuits. Each SLC supports 126 addressable devices. The wire run length for an SLC
using 16 AWG wire is up to 8,000 feet and can be wired in either a Style 4, 6, or 7 configuration.
Four programmable output circuits can be individually configured as notification appliance circuits (NAC) or
as 24VDC auxiliary power outputs. A dedicated non-resettable network power output is also provided. All
outputs are filtered. Notification appliance circuits can be wired either Style Z or Style Y, individually
programmed to be silenceable with or without a time delay. The notification circuit output pattern is
programmable for continuous output, march time, and ANSI temporal code. Auxiliary power outputs are
individually programmable to be continuous or reset. All inputs and outputs except relays and AC Line are
inherently power limited.
The panel comes with system alarm and system trouble relay Form C contacts, as well as a port to add up to
20 individually programmable system relays (four ZRMs).
A 5.75-Amp filtered, regulated switching power supply is standard. A 7.5-Amp power supply is optional. The
IPB-3 power supply can provide additional remote power.
The cabinet is constructed of 16-gauge red cold rolled steel. Conduit knockouts are provided on the top,
sides, and back. The removable door is secured with a key lock.
19.2 System Options and Expansion
The control comes standard with an RS-485 network interface to allow addition of several types of system
expansion modules. These include the Remote Display Annunciator (RDA) that duplicates the Local
Programming Display's LCD and buttons on the main panel, a remote LED driver (RLD) for driving graphic
annunciators, and conventional Style B or D initiating zones (TZB, FZA).
Because the TZB and FZA modules are serial network devices, the flexible Classic 2000 Mk II will allow you
to connect up to 120 existing zones of 4-wire or compatible 2-wire conventional smoke and heat detectors up
