Section 1: Introduction; Basic System Overview; 1: Hardware Features; 2: Common Communication / Annunciation Link System Hardware Features - Honeywell 6820 Manual

The 6820 and 6820EVS are analog addressable fire alarm control panels (FACP), that meets the requirements of UL 864. The 6820EVSana-
log addressable fire control system combined with an Emergency Voice System that meet the requirements for Mass Notification as
described in UL 864 and UL 2572.
NOTE: All references to the 6820 within this manual are applicable to the 6820 and 6820EVS unless otherwise indicated.

1.1 Basic System Overview

The 6820 is an addressable system with a built-in annunciator that can also be used to program the system.
1.1.1 Hardware Features
• The basic 6820 panel contains one built-in signaling line circuit (SLC), which supports up to 159 SK sensors and 159 SK modules or
127 SD SLC devices. Additional SLC loops can be added to increase overall point capacity.
• Additional 6815 SLC expanders supports 159 SK sensors and 159 SK modules for a maximum of 1,110 points per 6820 control panel.
• Additional 5815XL SLC expander supports only SD Protocol for a maximum of 635 points per 6820 control panel.
• 6.0A of output power is available through 6 sets of terminals for notification and auxiliary applications. Each circuit is power limited
per UL 864 and can source up to 3.0A (total output power must not exceed 6.0A). The constant auxiliary power load must not exceed
3.0A for normal standby.
• Built-in dual phone line, digital alarm communicator/transmitter (DACT), IP, or optional cellular technologies
• Reports events to central station by point or by zone
• UL-Listed for pre-action and deluge releasing systems
• Dedicated Form C trouble relay and two general purpose Form C programmable relays
• Can be used with up to 16 model 6860, 5860, or 6855 remote annunciators in any combination (sold separately)
• Supports the 5865-3, 5865-4, and 5880 LED annunciators for a maximum of 8 devices on the panel. See Section 4.13 and Section 4.14
for additional information on these models.
• Printing of event log available through the 5824 serial/parallel printer interface module
• Supports conventional 2-wire & 4-wire detectors using the 2 Flexput circuits or SLC zone modules
• Add four notification/auxiliary power circuits with each 5496 Intelligent Power Module
• Add six Flexput circuits with each 5895XL Remote Power Supply
NOTE: The system can support a maximum of 16 Intelligent Power modules, either the 5895XL or 5496, in any combination.
1.1.2 Common Communication / Annunciation Link System Hardware Features
The common communications and annunciation link allows up to 17 of the 6700, 6808, 6820, and 6820EVS panels to be connected via cop-
per or fiber optic cable so that a designated panel is the communicator for all panels in the link. This is not a true peer-to-peer network and
will not perform like one.
• The default common communications link setup can contain up to 17- 6820 panels connected.
• Common communications link support for up to 17 sites
• Each building is referred to as a "site".
• Panels can be interconnected using CLASS B or CLASS A topology.
• Use the SK-NIC Network Interface Card as a Common communications link. Copper wire or fiber optic cable panel connectivity can be
used within the same linked system.
• The common communication and annunciation architecture allows a designated panel to be the communicator for all the panels in the
link.
1.1.3 Software Features
• 999 software zones, 999 output groups
• Advanced analog smoke detector features:
– Automatic drift compensation
– Maintenance alert region
– Point status meets calibrated smoke test requirements for NFPA 72
• "JumpStart AutoProgramming" feature for easy programming
• Non-volatile event history stores 1000 events per panel
• A choice of output patterns available for notification outputs, including ANSI 3.41 temporal signal
• Built-in synchronization appliance support for AMSECO®, Gentex®, System Sensor®, and Wheelock®
