The 6820EVS integrates an Emergency Voice System that meets the requirements of UL 864 and UL 2572.
1.1
Overview of Basic System
The 6820 and 6820EVS base system is an addressable system with a built-in annunciator that can also be used to
program the system.
1.1.1
Addressable Fire Alarm Control/Communicator Hardware
Features
•
The 6820 and 6820EVS 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 per loop for a maximum of
1110 points per 6820 or 6820EVS control panel.
•
Additional 5815XL SLC expander supports only SD Protocol for a maximum of 635 points per 6820 or
6820EVS control panel.
•
6.0A of output power is available through 6 sets of terminals for notification. 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 max 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.
•

•
Basic system operation can be performed using a key or a user code.
•
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 in any combination for a total of eight devices on one control panel.
•
Printing of event log available through the Model 5824 serial/parallel printer interface module.
•
Supports conventional 2-wire & 4-wire detectors using the 2 Flexput™ circuits.
•
Add six Flexput™ circuits with each 5895XL Intelligent Power Module. See note below.
•
Add four notification/auxiliary power circuits with each 5496 Intelligent Power Module. See note below.
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 copper 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.
