WBI-2671
DESCRIPTION
The WBI-2671 is a BACnet MSTP device
that allows Douglas WRS-2224 Relay
Scanners to send and receive BACnet
commands to or from a BAS.
The WBI-2671 Node uses RS-485
networking technology that uses native
BACnet MSTP protocol.
Building Management Systems can
configure and program from their database
all of the functions inherent in the WBI-2671
and the WRS-2224.
The WBI-2671 conforms to the open
native BACnet variables for lighting.
The WBI-2671 allows programming,
control and monitoring of 5 groups.
The WBI-2671 allows control and
monitoring of 24 relays individually.
The WBI-2671 allows control and
monitoring of 5 switch inputs.
The WBI-2671 allows programming, either
from the WRS-2224 or the Network, of a 2-
hour Time Out or a 5-minute Flick Warn.

BACnet Node for WRS-2224 Scanner
Interface type: MSTP over RS-485
- This node does not have a built-in end of the line termination resistor.
Installer's responsibility to correctly terminate the RS-485 data bus.
- Transmission Baud Rate is selectable, select appropriate baud rate
for the system this node is installed to.
- For information regarding BACnet object types supported, refer to
product cutsheet available at Douglas web site.

BACnet ® Node for Douglas Scanner
WBI-2671
Technical Data
EXTERNALLY CONFIGURED NETWORKS
Integrated Systems
Douglas Relay Panels can be incorporated into Building
Management Control Systems that use BACnet technology.
It is assumed that the BMS supports standard BACnet objects
that can be used for lighting control.
The WBI-2671 Node plugs into the WRS-2224 Relay Scanner
and is connected to the BACnet network.
Individual relay and groups status indicators are available on the
keypad on the attached relay scanner.
Individual relay and group momentary overrides are available on
the keypad on the attached relay scanner.
MAC Address and Configuration
The MAC Address (0-255 address range) for each WBI-2671 is set
using the binary DIP switch on the WBI-2671 unit.
The Device ID for each WBI-2671 is set using a variable accessible
via the BACnet MSTP port.
WBI-2671 FUNCTIONS & FEATURES
Activates a group (one command per group).
Reads the group status (one command per group).
Activates relays (one command per relay).
Reads 'enhanced' group status (one command per
relay: 0 = Absent, 1 = ON, 2 = OFF, 3 = Defective).
Activates a group switch (changes the state, one
command per switch).
Reads a group switch (monitors the state, one
command per switch).
Reads the module status (version numbers and address).
Provides remote programming of the five scanner
resident groups (including Flick Warn, Time Out and
Flick Warn with Timeout options).
Querys programming of the five scanner resident
groups (including Flick Warn, Time Out and Flick Warn
with Time Out options).
Provides local programming of the five scanner resident
groups (by the keypad on the attached scanner).
