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 dang er

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:.

AZW-5000

• Coordinator - connects to the committed MS/TP network. Sends and

receives system data to/from transceivers.

Dimensions

• 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.

About AZW-5000

Figure 2 Typical AZW-5000 implementation

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.

Installation and Operations Guide

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.

General installation guidelines

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.

AZW-5000

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

Installation and Operations Guide

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.

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.
