WNX-2624
PART No.
DESCRIPTION
SPECIFICATION
WNX-2624
The WNX-2624 Networking Node is a
member of the Douglas "SwitchPoint"
product group. The WNX-2624 permits
Douglas WRS-2224 Relay Scanners to
be networked together.
The WNX-2624 Node uses state-of-theart LonWorks® networking technology
and is LonMark® certified (3.1).
WNX-2624 nodes can be networked in
one of 2 methods.
1) Self configured network (default)
2) Externally configured network
Self-Configured Networks
Self-configured networks are ideal for
expanding the number of relay outputs
controlled by a scanner switch input.
When networked, the switch input of a
scanner has global reach and can
control any quantity of relay outputs
throughout the system.
Externally Configured Networks
Other controls systems that use LonWorks
technology can digitally integrate the
WNX-2624 as a part of their system. The
WNX-2624 node is LonMark certified to
ensure reliable, compatible operation with
other systems that utilize LonWorks
standards.

Data Signal
The Douglas SwitchPoint System provides a versatile networking
platform for standard Douglas lighting control components. The
SwitchPoint products operate in parallel with switches and
sensors that may be connected directly to the relays. The
foundation of the system is the scanner/node combination.
The SwitchPoint System is easy to install and provides a simple,
easy to use network that allows an input to control any group of
relays in the building.
By attaching a WNX-2624 Network node to a WNX-2224 relay
scanner a simple, self-managed network can be established. The
WNX-2624 nodes are connected together with a data signal that
uses #16 AWG, twisted pair wire with no shield. The data signal is
wired in sequence from node-to-node. Wiring also supports tee
and branch lines that connect to other nodes.
Total data signal length should not exceed 1300 feet (400m). If
longer lengths are required, wire signal from node-to-node in
sequence (no tees or branches) or use a repeater.
The WNX-2624 Scanner Node is LonMark certified to ensure
reliable, predictable operation with other control systems that
integrate Douglas relay panels as a part of their system.

relay outputs that are controlled by an input. Common applications
include master switch stations that are connected to inputs
located at the nearest relay panel. The inputs are programmed to
switch any group of relays throughout the system. A Douglas
WTP-4408 time clock or WPC-5577 photocell can also be
connected to an input to provide automatic network control.
A self-configured network only requires the network nodes to be
plugged into the relay scanners and connected together via data
line. For one of the network nodes, set the network manager
switch to "ON" so that that node also performs the network
manager functions.
Use the membrane key pads built into the devices to program
which relays are controlled by an input. Any relay output that is
part of the network can be programmed to an input.
Each relay scanner has 5 inputs and 24 relay outputs. If additional
inputs are required at a location, use the WNS-2308 Networking
Node with 8 Inputs.
A self-configured system can support up to 24 nodes. This
provides over 500 relay outputs and 120 inputs.
The flick warn option supported by a stand-alone WRS-2224
Relay Scanner is also supported on the self-managed network. If
the input has this option selected with the keypad of the WRS2224, the system wide relay group will have the same flick
feature. The WNS-2308 also supports the flick warn feature.
The WNS-2308 unit has additional features that allow the inputs to
accept control from devices that do not use the Douglas 2wire
switching method. Contact closures of maintained or momentary
nature are easily interfaced to the WNS-2308.

LonWorks Data Signal Wiring
• The Douglas network nodes use FTT-10 transceivers to carry the
LonWorks Data Signal. The FTT-10 transceiver is well suited for
a building environment. It is robust, has a great deal of noise
immunity and supports free topology installation.
• The FTT-10 transceivers (Free Topology Transceiver) support
"free topology" wiring. Free topology allows the installer to branch
and "T" the data signal as required. In addition, the data signal
has no polarity and connections can be made to devices in either
direction. As a comparison, RS-485 transceiver systems can only
be wired as a bus (nodes wired in succession with no branches in
wire) and the wire pair is polarity sensitive.
• Data Signal total wire lengths:
- Free topology connections: 1300 feet (400meters) maximum.
- Serial bus connections: 5000 feet (1500 meters) maximum.
(FTT-10 wired as a bus has improved range)
• Data Signal Polarity: None
Douglas nodes can be connected to the wire pair in either way.
• Wire Type: #16 AWG, twisted pair, no shield, solid.
(Example: Belden #8471)
• Other wire types can be used, however results will vary depending
upon the wire type and gauge. Please contact factory for
information about different wire types.
• Do not install the data signal in close proximity (less than 3") to
higher voltage cables and conduit.
• If longer data signal wiring lengths are needed, use a repeater
(contact factory).
WLP-2999 Termination Unit
Self-managed systems only use the Lighting Panel Controller Object and
the Scene Panel Object. The Actuator and Switch Object are provided to
permit outside systems to operate individual relays.
DISTRIBUTED BY:
• The nodes used in either self-managed or integrated systems
each have a unique ID. Self-managed systems use the facilities of
one of the nodes to assign ID#s. This node is called the network
manager and has the network manager switch set to "on". Once
assigned, ID#s are permanently stored in the node and can only
be changed with a special procedure.
• When a WNS-2624 or WNS-2308 node is first used it does not
have a system ID. When it is connected to a self-managed system
the system will recognize that the node is present and has no ID.
The system will then assign to the node an available ID (a number
from 1 to 24).
• If all of the nodes of a self-managed system have no ID, the ID
numbering process may take a few minutes. Once assigned, the
ID numbers are retained indefinitely. Adding new nodes in the
future causes the auto ID process to occur for the added node.
• Integrated systems assign ID numbers with the system manager
used by the integrated system. When a node is configured by an
outside, integrated system, the network manager switch of the
node is automatically disabled to prevent any network
management conflicts with the integrated system manager.
• The WLP-2999 terminator unit helps provide additional noise
immunity for the Data Signal wiring. The device is recommended,
but is optional and lack of use will not affect warranty. Best results
are obtained if terminator can be installed at approximately the
physical center of the network wiring.

2-WIRE RELAY TECHNOLOGY
Douglas 2-wire relays utilize an ingenious control method that
permits simple and minimal wiring. All functions for low voltage
control; on, off, indication and location are provided with only a
2-wire connection of which one is often a common. All Douglas
relays manufactured over the past 25 years utilize the same
principle. Thus, any Douglas switching device is compatible with
any model of Douglas relay.

Operational Principle
■
■
■
■
■
A negative pulse turns the relay ON and a positive pulse turns it
OFF. Using a diode an AC signal can be rectified to turn the relay
either ON or OFF. Douglas switches have 2 diodes built into the
switch to provide the ON and OFF signals.
The relay has 2 similar diodes built inside that are in series with
the relay coil. The diodes in the relay act as gates for the switch
signal.
To turn the relay ON or OFF, the rocker switch completes the
circuit by selecting the ON or OFF diode. If the diode selected is in
the same direction as the gate diode in the relay, the relay will
switch. If the gate diode is not in the correct direction, then nothing
will happen since the relay is already in the correct state for the
action selected by the switch. When the switch is released, a
spring returns it to the central neutral position.
Indication (ON state) and location (OFF state) are obtained by
utilizing LED diodes built into the switch. Only the LED which is
connected in the same direction as the gate diode in the relay will
light. Although the LED current passes through the relay coil, it is
not large enough to cause the relay to trip. However, there is a
limit; the maximum amount of LED switches connected to the
same relay is 6.
For additional convenience (especially during installation) all
standard models now have a manual control lever and indicator
permitting a non-electrical method of switching and status check
at the panel.

INSTALLATION & ASSEMBLY
■
■
PWEx series relay panels for Douglas HID relays are supplied
with a separate interior. All of the components and barriers are
mounted to the interior.
(NOTE: If using MC-600 components, use RLI series panels.)
PWEx panels are primarily intended for projects where the interior
is factory pre-assembled. To install the relay panel the following
sequence is recommended:
1) Mount the empty enclosure onto the wall and pull wires. It is
recommended that all (or most) of the wires be pulled prior to
installing the interior. This will prevent component damage
from the wire pulling operation.
2) Relay line voltage terminals are sized for a maximum of
12AWG wire.
For low voltage wiring 18AWG solid is recommended.
3) Once the wires have been pulled, install the interior and bolt it
into place. Make line connections to relays according to the
panel schedule provided. If there is no schedule, identify
circuits on blank schedule.
4) To test circuit, turn circuit breaker off, use manual lever to turn
relay on and then turn on the circuit breaker. This will help
prevent relay contact welding due to dead shorts.
5) Verify that the schedule matches the lights operated by the
relay.
6) Once the line circuits are connected and verified, connect low
voltage switch wiring to relays or devices.
