Important safety information and installation
precautions
Read all instructions
Failure to follow all instructions may result in equipment damage or a hazardous condition. Read all instructions
carefully before installing equipment.
Local codes and practices
Always install equipment in accordance with the National Electric Code and in a manner acceptable to the local
authority having jurisdiction.
Electrostatic sensitivity
This product and its components may be susceptible to electrostatic discharge (ESD). Use appropriate ESD
grounding techniques while handling the product. When possible, always handle the product by its non-electrical
components.
High voltage safety test
Experienced electricians, at first contact, always assume that hazardous voltages may exist in any wiring system. A
safety check using a known, reliable voltage measurement or detection device should be made immediately before
starting work and when work resumes.
Lightning and high-voltage danger
Most electrical injuries involving low-voltage wiring result from sudden, unexpected high voltages on normally
low-voltage wiring. Low-voltage wiring can carry hazardous high voltages under unsafe conditions. Never install or
connect wiring or equipment during electrical storms. Improperly protected wiring can carry a fatal lightning surge
for many miles. All outdoor wiring must be equipped with properly grounded and listed signal circuit protectors,
which must be installed in compliance with local, applicable codes. Never install wiring or equipment while standing
in water.
Wiring and equipment separations
All wiring and controllers must be installed to minimize the possibility of accidental contact with other potentially
hazardous and disruptive power and lighting wiring. Never place 24VAC or communications wiring near other bare
power wires, lightning rods, antennas, transformers, or steam or hot water pipes. Never place wire in any conduit,
box, channel, duct or other enclosure containing power or lighting circuits of any type. Always provide adequate
separation of communications wiring and other electrical wiring according to code. Keep wiring and controllers at
least six feet from large inductive loads (power distribution panels, lighting ballasts, motors, etc.). Failure to follow
these guidelines can introduce electrical interference and cause the system to operate erratically.

About AZW-5000
Alerton’s AZW-5000 is a wireless communications device designed to replace
MS/TP and wall sensor cabling in instances where cabling is cost-prohibitive. It
allows you to add a small (up to 15 controllers or devices) wireless subnetwork
to a wired network.
A scenario where the AZW-5000 would be effective is a school that adds
portable class rooms that need to be tied into the existing school Building
Automation System (BAS). The cost of running cable underground to each
portable is significant. AZW-5000 is an ideal solution to this problem allowing a
wireless network to make the connection for a lower price than the labor and
materials needed to bury a cable.
It will also be useful when retrofitting wireless controllers into places where
wiring or rewiring is prohibitively expensive - buildings with concrete walls, for
example.
The AZW-5000 operates in one of three modes:.
•Coordinator - connects to the committed MS/TP network. Sends and
receives system data to/from transceivers.
•Transceiver - connects to a unitary controller by an MS/TP cable. Also
supports a wireless sensor by communicating data between the unitary
controller and the wireless sensor. Sends and receives system data
to/from the coordinator.
•Repeater - Connects only to power. Repeats transmissions in areas of
weak reception. Note that the use of repeaters reduces the overall
bandwidth of the network.

AZW-5000 network topology
Figure 2 shows a typical, stand-alone, AZW-5000 implementation. For examples
of other topologies, see the System Design Guide (LTBT-TM-SYSDSGN).
Items to note in relation to Figure 2:
• The maximum number of AZW-5000 devices on a network is 16 (1
coordinator and 15 transceivers/repeaters).
• The AZW-5000 connected to the BCM-ETH must be configured as a
coordinator. This device manages the wireless network.
• The coordinator must have a dedicated BCM-ETH or BCM-MSTP. Do
not connect multiple MS/TP devices to the coordinator’s BCM.
• An Alerton Wireless Temperature Sensor cannot be associated with a
coordinator or a repeater.
• An AZW-5000 transceiver or repeater may be associated with only one
WTS. Both must share the same ZigBee MAC address.
• Locating a transceiver more than 100 feet from the coordinator may
degrade data transfer rates.

General installation guidelines
This section provides guidance for wiring and powering Alerton controllers. For
installation instructions specific to AZW-5000, see “Installation” on page 14.
Using terminal blocks
The AZW-5000 uses header-style termination blocks to simplify field wiring of
power, communications, and I/Os. Terminal blocks accept wire gage from
12–24AWG.
To terminate wire to a AZW-5000
1. Strip approximately 1/8” of the wire jacket from the end of the wire.
2. Use a small screwdriver (1/8” max) to turn the adjustment screw fully
counter-clockwise. The clamps in the wire slot separate as you turn the
screw.
3. Insert the stripped end of the wire into it (try to get the jacket flush with
the terminal block). If using stranded wire, be sure to insert all strands
into the wire slot. If terminating multiple wires, trim wires to same
length and tightly twist exposed wire together.
4. Hold the wire in place and turn the adjustment screw clockwise to
tighten it until the clamps in the wire slot secure the wire.
5. Tug gently on the wire to ensure it is secure.
Power supply guidelines and requirements
AZW-5000 uses 24VAC power from a UL Listed Class 2 24VAC transformer
(not provided). The AZW-5000 uses a half-wave rectifier to convert the AC
power supply to onboard power. This enables multiple devices with half-wave
power supplies to be powered from a single, grounded transformer. When
sharing a transformer make sure the sum of the MAX loads for all connected
devices does not exceed the Load rating for the transformer. AZW-5000
maximum power consumption is <5VA.
CAUTION Half-wave devices and full-wave devices must not use the same AC
transformer. If a AZW-5000 will share its power supply with another device,
ensure that the other device uses a half-wave rectifier and that polarity of wiring
is maintained. Failure to do so can result in equipment damage.
Note All Alerton unitary controllers are half-wave devices.
Selecting a transformer
The safest way to size a transformer is to ensure that the maximum VA load
rating of the AZW-5000 is less than 85% of the Nameplate VA rating of the
transformer. Even if all outputs are not presently used, this ensures that each
AZW-5000 has sufficient power for future equipment additions.
CAUTION If an AZW-5000 will share its power supply with another device,
ensure the transformer is rated to handle the combined maximum load. Using
and undersized transformer may damage equipment.
IMPORTANT Transformer sizing should never exceed the maximum UL Class
2 rating.

Power supply grounding and wiring
When connecting power to the AZW-5000, ensure that one leg of the VAC
secondary circuit connects to a known earth ground. Also ensure that the GND
terminal on the AZW-5000 connects to the same known earth ground.
Supplying a high-quality ground connection to a AZW-5000 and then properly
connecting the AZW-5000 to the ground is one of the most important things you
can do to ensure a trouble-free installation.
The 24VAC secondary leads are not interchangeable. Once a lead connects to
the GND terminal on the AZW-5000, it is the grounded lead. Observe and
maintain polarity for subsequent connections. The GND terminal provides a
reference ground for the circuit board and communications wiring. Use 18 AWG
cable for best results.
WARNING Ensure that all AZW-5000 power, communications, and I/O
cabling are grounded according to these instructions. Failure to follow these
instructions may result in AZW-5000 operational and communication failures or
equipment damage.
Power supply wire selection
If you are considering long power supply wiring runs, using the right wire size is
critical. If the wire diameter is too small, the resistance may be too high,
resulting in a low voltage supply to the AZW-5000. This is known as line loss.
The wire size is based on the length of the wire run and the current draw of the
AZW-5000. Obtain additional information from the transformer manufacturer.

MS/TP LAN wiring
The AZW-5000 coordinator device communicates with the BACnet system over
the MS/TP LAN, which uses the EIA–485 signaling standard. Transceivers
communicate with their associated unitary controllers over
Note This section applies only to the coordinator device.
Terminating MS/TP LAN cabling
MS/TP terminations are located at the top of the AZW-5000. See Fig. 4 on p. 15.
Maintain polarity of the MS/TP wire run throughout the MS/TP LAN.
Note Basic information about MS/TP terminations at the AZW-5000 are
provided here. See the BACtalk System Design Guide (LTBT-TM-SYSDSGN)
for more detailed information and limitations with respect to MS/TP LANs —
distance requirements, unit loads, repeater architectures, and so on.

Layout Bus.
Cabling BACnet specifies the following. Shielded, twisted-pair
cabling with characteristic impedance between 100 and
130 Ohms. Distributed capacitance between conductors
must be less than 30 pF/foot (100 pF/m). Distributed
capacitance between conductor and shield must be less
than 60 pF/foot (200 pF/m). Foil or braided shield
acceptable.
Segment length Segments between transceivers and controllers/devices
should be kept as short as practical to reduce cable
costs. Longer segments are acceptable to improve radio
signal strength.
The segment between a coordinator and its associated
BCM can be up to 4000 ft. (1071 m.), but will typically
be much shorter.

Grounding the MS/TP LAN shield
Proper shield grounding of the MS/TP cabling can help minimize the risk of
communications problems and damage to equipment because of transient
voltage spikes (for example, lightning strikes).
Follow these guidelines for grounding MS/TP cable shields:
• Each transceiver MS/TP segment should have a single point of shield
ground, preferably as close to the middle of the cabling run as possible.
• Do not ground the MS/TP shield to an AZW-5000 GND terminal.
• Do not ground both ends of a shield. Differences in potential between
the grounds may induce current on the shield, causing interference.
• At ungrounded, exposed shield points, tape back the shield to the wire
jacket or, for optimum transient shunting, use 100V gas discharge tubes
or 120V MOVs between the shield and ground.

Installation
This section explains how to mount and wire individual devices once they are
configured.
After all AZW-5000 devices are installed, ensure that only the coordinator is
wired to the primary BAS MS/TP network. Wiring multiple AZW-5000s to the
primary MS/TP network will cause routing loops.
WARNING Thoroughly read all instructions before mounting and wiring.
Install equipment in accordance with the National Electric Code, these
instructions, and in a manner acceptable to the local authority having
jurisdiction. Failure to do so can result in bodily injury or equipment damage.
Mounting
Choose a mounting location that minimizes the amount of interference for radio
communication with the nearest node. Do not mount in a metal box or in a
fiberglass box impregnated with ferro magnetic` materials. Leave at least six
inches above the device for connecting wires and an external antenna (optional).
Some points to consider when selecting a location:
• The effective communication range is 50 feet (through two non-metal
walls).
• Any metal (ducting, equipment, metal studs, and so on) near the device
or between two devices will impede radio waves.
• If a wall has metal components (studs, ductwork, and so on) radio waves
will tend to travel along the plane of the wall. Mounting the device on
the same wall as other device(s) will increase signal strength.
• When mounting near ductwork or other metal, use double-sided tape to
temporarily mount the device while testing radio reception.
• Mount the AZW-5000 indoors only.
DIN rail mounting
To mount the AZW-5000 on a DIN rail
1. Hold the device with its top tilted toward the DIN rail and then hook the
two top tabs on the back of the device onto the top of the DIN rail.
2. Push down and in to snap the bottom flex connector onto the DIN rail.
To remove the AZW-5000 from a DIN rail, push straight up from the bottom to
release the top tabs and then pull the top of the device outward.
Wall mounting
To mount the AZW-5000 on a wall, position the device in any orientation and
secure it to the wall with size 6 or 8 screws appropriate for the mounting surface.
Attaching an external antenna (optional)
The AZW-5000 has two internal antennas that will meet the requirements of
most applications. If you need additional range or if the device is mounted in an
Installation and Operations Guide

area not accessible to radio waves, you can connect an external antenna. Before
connecting an external antenna to improve radio signal strength, try moving the
AZW-5000.
A compatible antenna is available from www.antennafactor.com, part number
ANT-2.4-CW-RCT-SS.
The cable must have a male SMA on one end and a female SMA on the other.
To mount an external antenna
1. Set the MS/TP MAC address DIP switch 8 to ON (up). Note that this
sets AV-31 present value to 2 (external).
2. Screw the antenna onto the terminal at the top of the device.
3. If necessary, use an RF cable to relocate the antenna. Use a cable with a
maximum signal loss of 1 dB.
Wiring
Once the AZW-5000 is mounted, connect the MS/TP and power.
Figure 4 Wiring diagram
Connecting MS/TP
If the unit will function as a repeater, skip this section.
Connect the device to its parent controller using cabling that meets the EIA–485
signaling standard. Use shielded, twisted-pair cabling with characteristic
impedance between 100 and 130Ω. Distributed capacitance between conductors
must be less than 30 pF/foot (100 pF/m). Distributed capacitance between
conductor and shield must be less than 60 pF/foot (200 pF/m). Foil or braided
shield is acceptable. Maintain wiring polarity.
Connecting power
Connect the AZW-5000 to 24VAC power from a UL Listed Class 2 24VAC
transformer (not included).
CAUTION The AZW-5000 is a half-wave device. Do not connect half-wave
devices and full-wave devices to the same AC transformer. If the AZW-5000
will share its power supply with another device, make sure that the other device
uses a half-wave rectifier. Maintain wiring polarity.

Adding Alerton Wireless Temperature Sensors
© Honeywell LTBT-TM-AZWIOG Rev. 0001BETA 19
Adding Alerton Wireless Temperature Sensors
The Alerton Wireless Temperature Sensor (WTS) integrates with the AZW-5000
to add programmable space temperature control without the expense of cutting
walls and running wires. The WTS is available in two models: one with a
temperature adjustment knob and manual override, and one without.
A WTS differs from other devices you might add to an AZW-5000 network
because it does not need to be wired to a transceiver. It has an internal radio that
acts as its transceiver.
You can pair a WTS with an AZW-5000 transceiver or repeater, but not with a
coordinator.
To pair a WTS with an AZW-5000
1. Set up the WTS using the WTS Installation Instructions
(LTBT-TM-WTS-INST-USA).
2. Set the WTS DIP switches labeled S2 and S3 to match the ZigBee MAC
address DIP switches on the associated AZW-5000.
WTS AVs and BVs
When a WTS device is connected to the network, the associated AZW-5000
reads its AVs and returns the values shown.
Note Setpoint Adjust Range is set using AV-25 in the AZW-5000.
You can change the AZW-5000 points to which the values are written by setting
these AZW-5000 AVs:
• AV-84 specifies where the temperature sensor reading is written
• AV-85 specifies where the temperature setpoint is written
• AV-86 specifies where the occupancy override status is written
• AV-87 specifies where the battery status is written

Maintaining an AZW-5000
This section explains how to update the ROC file, replace an AZW-5000 device,
and view commissioning data for a device.
Updating the real-time operating code (ROC) file
AZW-5000 has downloadable software called real-time operating code (ROC
file). The ROC file is the brains of the device and handles the more complex
functions of the AZW-5000 (object support, behaviors, and so on). The ROC file
can be downloaded whenever a software upgrade is necessary.
To upgrade the ROC file, copy the latest ROC file from the ASN and then use
BACtalk operator workstation software to send the ROC file to the device.
ROC file version
When servicing an AZW-5000, communicating with Alerton customer support,
or reading documentation, you may need to know the version of an AZW-5000
ROC file. AZW-5000 ROC file information is available in Envision for BACtalk
software as the application-software-version property of the AZW-5000 Device
object.
To view the ROC version, use BACtalk operator workstation software to open a
display template showing its device properties.
Replacing an AZW-5000
The process for replacing a failed device is the same as setting up a new device -
with one exception: you must set the DIP switches on the replacement device to
match those on the one being replaced. See “Configuration” on page 11 to start
the process.

Troubleshooting
Troubleshooting weak reception
If you are having trouble getting a good signal:
1. Switch the orientation of the internal antenna by changing AV-31
(0=vertical, 1=horizontal).
2. Move the device to reduce interference.
3. Add an external antenna. See “Attaching an external antenna
(optional)” on page 14.
4. Add another AZW-5000 device to act as a repeater. Note that the use of
repeaters reduces the overall bandwidth of the network.
Troubleshooting RSSI flash sequences
The RSSI LEDs show radio signal strength, but will flash if an error occurs.
RSSI flash sequence Error Condition Recommended Actions
One red No communication or the device has
not joined the ZigBee network
Ensure the device has the same Extended PAN
ID and security key as the coordinator.
The device may not be in range of another
AZW-5000. See “Troubleshooting weak
reception”.
One yellow and two
green
ZigBee MAC address does not match
device type
For the coordinator, make sure the ZigBee
MAC address is zero.
For transceivers and repeaters, make sure the
ZigBee MAC address is not zero.
Two green Multiple devices have identical ZigBee
MAC addresses
1. Remove power from all devices showing
this sequence.
2. Use Envision for BACtalk to configure
unique ZigBee MAC addresses for each of
the devices.
3. Wait one minute and then apply power.
One red and one green Coordinator - no other devices on the
ZigBee network.
Transceiver or repeater - lost
communication with the coordinator.
Note: This sequence will flash
momentarily and then revert to a single
red flashing LED.
The device may not be in range of another
AZW-5000. See “Troubleshooting weak
reception”.
Check the radio signal strength of the
coordinator. See “Checking radio signal
strength” on page 16.
One flashing red and
two solid green
The device has joined the ZigBee
network, but has not yet joined the
BACnet network.
Be patient. It can take up to three minutes for a
device to join the BACnet network.

Troubleshooting devices not found by device scan
If a device does not appear in the results of a device scan:
1. Check LEDs for power, radio signal, and MS/TP activity.
2. Check RSSI LEDs for error flash sequences (see “Troubleshooting
RSSI flash sequences” on page 22).
3. Check wiring, especially polarity of 24 VAC.
4. Pull up the coordinator in device template 99100017 and verify that the
Device Type is 0.
5. If the device is a transceiver, swap it with the coordinator and scan
again.
6. Pull up the problem device in device template 99100017 and check the
parameters:
7. (Advanced Users) Pull up the device in template 99100014 and check
these parameters:
Troubleshooting erroneous WTS temperature readings
If you encounter a faulty reading from a wireless temperature sensor (WTS), it
may be caused by two WTS devices with the same ZigBee MAC address. Check
that each WTS in the system has a unique ZigBee MAC address. Also check for
WTS devices that are not part of the system but may be transmitting temperature
readings (test devices, other systems, and so on). Remove the batteries from
unused units to prevent conflicts.

RSSI trending RSSI for a particular AZW-5000 r Can be used to trend RSSI for a particular device.
For example, suppose you have a transceiver with a ZigBee DIP switch setting
of 4 (device 1004), and want to setup a trendlog to monitor the RSSI value to
that transceiver from the coordinator (device 1000). Set up a trendlog in the
BCM monitoring AV-20004 in the coordinator. The value returned by
AV-20004 is the RSSI value between device 1000 and device 1004.
