3.3 Initial Wiring

3.3.1 Pass Wires into Enclosure

Pass the signal and AC power wires into the enclosure via the cable glands.
Figure 3-3, below shows the recommended use of the included cable glands.

Signal Wires | Antenna | AC Power Cable

Figure 3-3. HPWS Enclosure Connections

The cable glands provide a watertight seal that will protect the enclosure in case
of normal rain, ice, or snow when the cables are installed correctly. In order for
the enclosure to be weatherproof, it is necessary to tighten the cap of the strain
relief of the cable gland to ensure a proper seal. If space remains in the cable
strain relief after the cap is tightened, reinsert wires using a cable fitting to
eliminate any path for moisture.

The HPWS has been tested to NEMA 4X (IP66) standards, but
has not been tested for use in extreme rain, sleet, snow, wind,
or other abnormal weather conditions.)

3.3.2 Connect Signal Wires To Barrier Strip

Connect Signal wires from up to four (4) switches to the barrier strip as shown in
wiring diagram below.

If less than four switches are being used, do not connect any wires to that
channel on the terminal block.

NOTE:

Figure 3-4. Barrrier Strip Connections (Model HPWS-TX)

3.3.3 Connect AC Power

Only connect the HPWS unit to an AC power source of
115VAC, 60Hz, 0.95Amp, or 230VAC, 50Hz, 0.6Amp. The
power supply is not designed to work with other power modes.

Ensure the power switch on the power supply is selected to OFF before
proceeding and that power is completely disconnected from the unit.

Connect the AC Ground wire to the grounding bus bar located on the steel sub
panel. Ensure the ground wire is securely locked to the grounding bar using the

3.3.4 Connect Battery

Sealed Lead Acid (SLA) batteries may get hot, explode or
ignite and cause serious injury if exposed to abusive
conditions. Be sure to follow the safety warnings listed below:

Your HPWS operates with one 12V, 5Amp-Hour SLA Battery (Omega
Replacement Part Number HPWS-BATT). Never operate your HPWS
transmitter or receiver with a different battery than what is specified in this
manual or on the HPWS Series data sheet. Do not discharge the battery using
any device except your HPWS unit. When the battery is used in devices other
than the specified device, it may damage the battery or reduce its life expectancy.
If the device causes an abnormal current to flow, it may cause the battery to
become hot, explode or ignite and cause serious injury. Refer to the Omega
technical data sheet or this manual for the temperature ranges over which the
battery can be operated. Use of the battery outside this temperature range may
damage the HPWS or reduce the performance and life of the battery.

WARNING:

• Do not store batteries with other hazardous or combustible materials.

• Do not install the battery backwards so the polarity is reversed.

• Do not connect the positive terminal and negative terminal of the battery to
each other with any metal object (such as wire).

• Do not carry or store the battery together with metal objects.

• Do not pierce the battery with nails, strike the battery with a hammer, step on
the battery, or otherwise subject it to strong impacts or shocks.

• Do not solder directly onto the battery.

• Do not expose battery to water or salt water, or allow the battery to get wet.

• Do not disassemble or modify the battery.

• When the battery is discharged, insulate the terminals with adhesive tape or
similar materials before disposal.

• Immediately discontinue use of the battery if, while using or storing the
battery, the battery emits an unusual smell, feels hot, changes color or
shape, leaks or appears abnormal in any other way. Contact Omega if any
of these problems are observed.

• Do not place the battery in microwave ovens or high-pressure containers.

• Always dispose of discharged batteries in accordance with all local, state and
national laws.

Once the battery is connected, it will immediately begin to
power the unit, even if the power supply is set to off. The
ON/OFF switch only controls AC power. As a result, only
connect the battery when the unit is ready for use.

Do NOT connect the battery until just before the unit is ready for use—the unit
will receive power as soon as the battery is connected. Once battery is connected,
place power switch in the ON position to run the unit using AC power. When
device receives AC power, the power supply will charge the battery.

To connect the battery:

Attach the connectors from the battery lead wire to the terminals of the battery.
The battery may come with plastic protective covers attached to the terminals –
remove if necessary.

The connector with a red wire connects to the positive (+) terminal, which is
shaded red.

The connector with a black wire connects to the negative (-) terminal, which is
also shaded black.

3.4 Connect External Antenna

Connect the antenna (included) to the UHF connector on the outside of the
antenna.

Section 4 - Receiver Operation

The HPWS-REC receivers come in two different versions:

• HPWS-REC: 4-Channel 27.255MHz Switch Receiver without battery backup

• HPWS-REC-BATT: 4-Channel 27.255MHz Switch Receiver with battery
backup

In this manual, HPWS-REC will refer to both versions, unless
otherwise noted.

4.1 Switch Operation

The HPWS-REC receiver will trigger a relay output, when appropriate, of up to
1A at 32Vdc per channel when the switch on a respective channel is activated by
the transmitter.

4.2 Initial Setup

4.2.1 Open Transmitter Enclosure

Open Transmitter Enclosure by unscrewing the four (4) screws on the lid.

4.2.2 Pass Wires Into Enclosure

Pass the signal and AC power wires into the enclosure via the cable glands. This
watertight seal will protect the enclosure in case of normal rain, ice, or snow
when the cables are installed correctly. Tighten the cap of the strain relief on the
cable gland to ensure a tight seal. If space remains in the cable strain relief after
the cap is tightened, reinsert wires using a cable fitting to eliminate any path for
moisture.

Figure 4-1. HPWS Enclosure Connections

(Note, the unit has not been tested for use in extreme rain, sleet, snow, wind, or
other abnormal weather conditions.)

NOTE:

4.2.3 Connect Signal Wires To Barrier Strip

Connect signal wires for up to 4 outputs to the barrier strip as shown in wiring
diagram below. If less than four switches are being used, do not connect any
wires to that channel. The receiver assumes all switches are normally open
(N/O) switches.

Figure 4-2. Receiver Wiring Diagram - (Model HPWS-REC and HPWS-REC-BATT))

If using a normally closed switch, move the lead wire from the N/O terminal to
N/C terminal on the appropriate channel of the receiver circuit board. It is also
necessary to program the transmitter to N/C for the input signal wires (see
Section 6.3 for more details on normally closed switches).

In addition, the HPWS receiver offers a low battery and signal status alarm. The
low battery will switch up to 50mA @ 20Volts DC (with ground) when the
backup battery drops below 10.5 Volts. The signal status alarm will trigger when
the receiver has not received a transmission from a transmitter channel in the last
4 hours.

of these problems are observed.

• Do not place the battery in microwave ovens or high-pressure containers.

• Always dispose of discharged batteries in accordance with all local, state and
national laws

Once the battery is connected, it will immediately begin to
power the unit, even if the power supply is set to off. The
ON/OFF switch only controls AC power. As a result, only
connect the battery when the unit is ready for use.

Do NOT connect the battery until just before the unit is ready for use—the unit
will receive power as soon as the battery is connected. Once battery is connected,
place power switch in the ON position to run using AC power. When device
receives AC power, the power supply will charge the battery.

Section 5 - System Operation

5.1 Introduction

Compared to wired switch systems, wireless switches provide much simpler
installation. It is not necessary to lay wire or signal cables over long distances.

However, based on the physical principle of propagation of radio waves, certain
basic conditions should be observed. The following recommendations are provided
to ensure proper installation and correct operation of your wireless system.

5.2 RF Communication Basics

The HPWS-TX model sends wireless transmissions to a receiver unit. The receiver
unit processes the signal and creates an appropriate output. Radio signals are
electromagnetic waves; hence, the signal becomes weaker the farther it travels.

While radio waves can penetrate some solid materials like a wall, they are
dampened more than when a direct, line-of-sight path between the transmitting
and receiving antenna exists.

5.3 Basic System Overview

The HPWS wireless system is comprised of two main components: a transmitter
and a receiver. Up to four (4) switches can be observed by one receiver.

The receiver can accept signals from up to four (4) different transmitters,
provided each unit is transmitting/receiving on a common address code and a
net total of four (4) switches or less are being observed.

Figure 5-1. Basic System Overview

This system onerview would require the OM-AMPOLEMNT10
accessory. See page 2-1 for more information.

5.4. Transmitter/Receiver Operation

5.4.1 Button Operation

There are no external buttons on the transmitter or receiver enclosures.

Each unit has an on/off switch, located inside the enclosure on the power supply
circuit board. The on/off switch controls AC power only. Once the battery is
connected, the unit will be activated and powered by DC power.

To completely turn off the unit's electrical power, you must
disconnect the battery lead wires from the battery terminals

5.5. Environment/Operating Conditions

5.5.1 Environment

Omega’s wireless end devices and receiver units have been designed to be fixed­mounted and operated in an appropriate, clean environment. Care should be
taken to prevent the internal components of the HPWS wireless system from
being exposed to moisture, toxic chemicals, and extreme cold or hot
temperatures that are outside the specifications listed in this manual.

Operating your HPWS transmitter or receiver outside the
specified conditions listed in Section 7 of this manual may
cause your unit to malfunction and stop working correctly.

5.5.2 Operating Conditions

The following is a list of basic good practices you should apply when operating
your HPWS wireless system:

• Never operate your wireless device outside the recommended environmental
limits specified in this manual.

• Never operate your wireless device in flammable or explosive environments.

• Never use your wireless device in medical, nuclear or other dangerous
applications were failure can cause damage or harm.

• Never operate your transmitter with any other battery or power source than
what is specified in this manual or on the battery compartment label.

• No co-location with other radio transmitters is allowed. By definition, co­location is when another radio device or its antenna is located within 20 cm
of your transmitter and can transmit simultaneously with your HPWS unit.

• Never install transmitters within 20 cm or less from each other.

• Never use your transmitter as a portable device. Your unit has been designed
to be operated in a permanent installation.

• Never install and/or operate your transmitter closer than 20 cm to nearby
persons.

NOTE:

IMPORTANT:

• Never operate your transmitter with any other antenna than what is supplied
or listed here in this manual for approved use.

5.6 Determining and Maximizing Range

The available maximum range specified for the HPWS series system in this
manual is only achievable under optimum installation conditions. Mounting
height, obstructions in your Fresnel Zone, and ambient conditions can degrade
signal strength, resulting in shorter range. The following recommendations will
help to improve the range of the HPWS wireless system.

Be aware of the Fresnel Zone

The Fresnel Zone is a football shaped area that represents the path of best signal
strength between the transmitter and the receiver.

Figure 5-2. Fresnel Zone

This configuration would require the OM-AMPOLEMNT10
accessory. See page 2-1 for more information.

Position the receiver in a central location

When multiple transmitters are in operation, position the HPWS receiver in a
central space with equal distance to each transmitter, if possible.

Test your system before permanent mounting,

Before permanently mounting a HPWS transmitter or receiver, try moving the
devices or antenna to multiple locations and mounting angles to determine
which installation achieves best signal strength.

Mount antenna high from ground and away from walls

Avoid installing system components near the ground or floor (this will cause the
bottom portion of the Fresnel Zone to be obstructed) or near buildings’ external
walls. Walls can create interference and degrade signal strength.

Maintain a line of sight between antennas

Maintaining a line of sight between a transmitter and receiver unit will greatly
improve signal strength when compared to a system with obstructions in the
path between transmitter(s) and a receiver.

5.7 Mounting the HPWS Unit

The HPWS series of products have flanges at the top and bottom of the enclosure
for mounting the HPWS. Use four (4) screws to secure the flanges to a wall or
other solid object.

In addition, an accessory pole-mount kit can be used to mount the HPWS to a
pole. See secton 2.2 for more accessory information, and Section 1.5 for
Mounting Dimensions.

5.8 Installing the Antenna

The HPWS series operates on 27.255 MHz, which is part of the CB radio band.
Normal transmissions from the HPWS on the CB band do not require a license or
special approval.

The HPWS series comes with a 3-foot antenna and 18 feet (6m) of RG-58 antenna
cable. Up to 50 feet of RG-58 cable may be used to connect the HPWS antenna.

The HPWS uses UHF-Style (PL-259) connectors to connect the coaxial cable to
the antenna.

If more than 50 feet of cable is necessary to mount the antenna, up to 100
feet of RG-8 cable may be used to mount an antenna.

When mounting the antenna, it is important to comply with all FCC
regulations.

5.8.1 Antenna FCC Regulations

FCC regulations (§95.408) state the highest point of a CB antenna may not:

• “be more than 6.1 meters (20 feet) above the highest point of building or tree
the antenna is mounted upon” or

• “be more than 18.3 meters (60 feet) above the ground”

Installations near an airport are subject to stricter requirements. Check
with the local FCC office for more details if installing near an airport or
helipad.

NOTE:

NOTE:

NOTE:

FCC regulations are subject to change at any time. While every effort
was made to ensure that the regulations cited were up to date at time of
printing (November, 2010), it is important to make sure you check any
and all FCC (or other government) regulations appropriate to your use
before using a wireless product.

NOTE:

Section 6 - Advanced Features

6.1 Address Codes

Each transmitter and receiver has a programmable address code. When ordered
as a system, the transmitter and receiver will be factory programmed to
communicate via the same address.

There are 65,536 unique address codes that can be selected.

The address codes are selected by dip switches located on a circuit board within
the transmitter unit (The address switches are circled in yellow, below). During
standard operation, it is not necessary to adjust the address switches once they
are set.

To adjust the address codes, modify the dipswitches in Switch “A” and Switch
“B” as shown in Figure 6-1 to match that of the desired receiver (or transmitter).
If the switches do not match exactly, the transmitter and receiver will not
communicate with each other.

Figure 6-1. Address Codes On HPWS Receiver

The main product label (see Figure 1-1 in section 1.2)
includes a write-on surface to easily remember the address
code.

6-1

Advanced Features

NOTE:

ADDRESS CODE SWITCHES

6.2 Multiple Transmitters

To connect multiple transmitters to one receiver, each transmitter must be set to
the same address code as the receiver. See Section 6.1 for more information
regarding the address codes.

A maximum of four (4) switches can be observed by the receiver. If using
multiple transmitters, ensure each switch is transmitting on a different channel
but the same address.

Example: Transmitter A and B will communicate with a common receiver.
Transmitter A will send data regarding one (1) switch, while Transmitter B will
send data on the status of three (3) switches. Transmitter A should transmit
switch on CH1. Transmitter B should transmit its switches on CH2, CH3, and
CH4. Transmitter A and B should both have the same address code as the
receiver.

If a channel is not in use, simply leave the terminal block connections empty. No
signal will be broadcast.

If two different transmitters use the same channel to
communicate with a common receiver, incorrect signals will
be processed. This will result in unintended and potentially
dangerous operations.

Advanced Features

6

6-2

NOTE:

6.3 Normally Open vs. Normally Closed Outputs

The receiver unit can be programmed to transmit switch data as normally open
(N/O) or normally closed (N/C) switches. The factory default is to set all
switches to normally open. However, it is possible to change this setting at any
time. To change from N/O to N/C, it is necessary to adjust both the transmitter
and receiver.

The open/closed setting must match on the transmitter and its
receiver. If the transmitter and receiver are not set to accept
the same type of switch, undesired operations will occur.

(Transmitter Only)

To modify switch output from N/O to N/C, toggle the white input selection
switch for the appropriate channel. The input switches are located on a blue
switch block above the circuit board fuse.

Figure 6-3. Transmitter Dip Switches

The switch is in the default (off) position, which represents N/O. Setting the

switch to on (up) is N/C.

(Receiver Only)

To modify switch output from N/O to N/C, move signal wire (blue wire) from
the N/O terminal to the N/C terminal on the desired channel. Do NOT modify
the COM channel.

6.4 Status Alerts

The HPWS-REC receiver is able to receive transmissions regarding the signal
status of any associated transmitters. If the signal status alarm is activated, the
HPWS-REC series can be used switch up to 50mA at 20Vdc.

To activate or deactivate the status alert setting, adjust the status alert
dipswitches on both the receiver and the transmitter.

6.4.1 Location of the Status Alert Dipswitches On Transmitter

Transmitter: Switch 3 on the option switch box (below the address codes)
controls the transmitters status signal output.

6.4.2 Location of the Statue Alert Dipswitches on Receiver

Receiver: The dipswitches are located in the blue dipswitch box below the
address codes. The switch box is circled in yellow in the following figure.

Figure 6-6. Receiver Status Alert Dipswitches

On the receiver, status switches 1-4 control the status alerts for CH 1-4,
respectively. If the dipswitch is set to on, the receiver will require status updates
from the transmitter on that channel. Setting the dipswitch to off eliminates the
status report for that channel.

Transmitters will send status updates once every hour. If, after 4 hours, the
transmitter has not sent a signal status update, the receiver will trigger the status
alarm output.

The status alert output is on the Receiver only.

The HPWS has one status alarm output that is triggered by a
loss of status condition on ANY channel set to receive status
updates. To turn off the status alarm, it is necessary to set ALL
4 status dipswitches on the receiver to off.

6-6

NOTE:

STATUE ALERT DIPSWITCHES

6.5 Low Battery Alert (Receiver Only)

The HPWS-REC series of receivers are able to receive transmissions regarding
the battery status of any associated transmitters. If the voltage supplied to the
transmitter drops below 10.5V, the transmitter will send a low battery message,
triggering the low battery output on the receiver. This low battery alarm will
switch up to 50mA @ 20VDC.

The low battery output is marked on the barrier strip. It is not necessary to
adjust dipswitch settings to receive low battery output.

The low battery alert switch is on the Receiver only.

The HPWS has one battery alarm output that is triggered by
a low voltage condition on ANY transmitter communicating
with a common receiver.

6.6 Auto Restore (Transmitter Only)

The HPWS-TX transmitters can be programmed to transmit a momentary switch
signal instead of the traditional lock-and-hold signal. This function is known as
auto restore.

Manual Restore (factory default): The manual restore setting (Auto restore: off)
on the transmitter will cause the receiver to output a signal as long as a switch is
closed (or opened.)

For example, if an alarm should remain on as long as a level switch is triggered,
use manual restore function. The output will cease when the switch is returned
to its normal position.

Auto Restore: Auto restore allows the receiver to limit the maximum time a
switch can be closed before resetting. The receiver will trigger the output for up
to 30 seconds, or as long as the switch is active, whichever occurs first. After 30
seconds, the output will cease, regardless if the switch on the transmitter is still
closed. The output will not activate until the switch cycles again.

Using Auto Restore will terminate the signal output after 30
seconds, even if the switch is still activated. Auto restore is
useful in specific circumstances only, and should not be used
in a situation where an alarm needs to be on as long as a
switch is triggered.
