Overview
When installing and programming a Skymetry WTU-14 there are
several steps required for all installations. Listed below are those
required for a typical installation and start-up of the Skymetry
WTU-14.
1) Confirm wireless coverage for the installation site.
2) Select a wireless messaging plan and activate the unit.
3) Install the unit, set the input jumpers, and wire the sensors.
4) Go online locally and program the unit.
5) Wait for the web page to initialize and become active.
6) Verify status on the web site.
7) Test all sensors and alarm notification—see Chapter 11: Testing
the Skymetry WTU-14
Web Page Initialization
Your Skymetry WTU-14 is accessible via the internet at www.
skymetry.com. From the web page you can view status, make
programming changes, and even control outputs. Before any of
these features can be utilized, the unit must first initialize the web
server. This happens automatically immediately after your f irst local
programming session with the unit. As soon as you disconnect from
your first programming session the unit will begin to update the
web server with all of its programming. This may take an hour or
two depending on how many parameters were programmed. During
this initialization period it is recommended that the unit remain
powered on and no additional programming changes take place. For
detailed information on the Skymetry web page see Chapter 10.
Data Message Usage
Your Skymetry WTU-14 communicates over the wireless network
using data messages. These are transmitted whenever an alarm mes
sage is delivered, machine-to-machine command is sent, or a web
update is requested. The number of data messages used for each
type of transmission is shown below in the table:

Status Refresh to the Web Page
Programming Refresh to the Web Page9 to 115
The last item, Programming Refresh to the web, depends on how
many changes were made since the last update. Only items that have
changed will be sent. Typically, once the unit has been programmed,
additional programming changes are minimal. However, if you were
to completely reprogram the unit and change every parameter, then
the maximum number of data messages would be transmitted.
Technical Support
This instruction manual will help you install and program the
Skymetry WTU-14 properly. Be sure to read it completely before
beginning the installation process. If there are any questions or
problems that arise upon installation or operation, please contact our
Technical Support team:
The Skymetry WTU-14 should be mounted and operated in a
clean, dry environment. The unit must communicate to the wireless
network, so care must be taken not to install the unit inside a metal
cabinet or other location that will prevent the unit from receiving
a radio signal unless the antenna can be relocated to a location
free of obstruction. The unit is microprocessor-controlled and, as
a result, should not be installed near devices that generate strong
electromagnetic fields. Such interference is typically generated by
power switching equipment such as motors, contactors, or variable
frequency drives. Where this is unavoidable, mount the unit in a
separate, grounded steel enclosure with an external antenna (see
Appendix F: Accessories). A poor operating environment may result
in unwanted system resets and/or system lockup. The temperature
range the unit can operate in is -20°F to 158°F (-29°C to 70°C).
Activating your Skymetry WTU-14
Your Skymetry device must be activated on the wireless network
before you can send or receive messages
gramming is performed for the first time.
To activate your Skymetry WTU-14 device, fill out the activation
form included with the package and follow the instructions, or con
tact your sales representative with the device serial number.
Your Skymetry WTU-14 is activated when the “In Range” and

Antenna Information
The Skymetry WTU-14 comes with a unity-gain stub antenna
designed specifically for the frequency range required. In order
to comply with FCC RF exposure, the external antenna must be
mounted in a location where people will never come within 20cm of
the antenna. The gain of the antenna may not exceed 0dBi. For opti
mum antenna performance, there should be no metal objects within
close proximity of the antenna.
-
WARNING Do not over-tighten the antenna on the
Skymetry WTU-14; this may cause
permanent dam-
age to the device.
The antenna must be connected before the device is powered up.
Connecting the Power Supply
The Skymetry WTU-14 requires a 15VDC 800mA power supply
(part number FGD-8250) to operate. This power supply will charge
an external 12V battery (2–12AH) and provide the necessary power
to transmit messages over the wireless network.
WARNING: Do not substitute supplies with lower
capacity.
Connect the positive terminal of the Power Supply to the +Vin ter
minal on the Skymetry WTU-14.
Connect the negative terminal of the Power Supply to the -Vin ter
minal on the Skymetry WTU-14.

Connecting a Battery
In the event of a power failure, the Skymetry WTU-14 can operate from a 12V sealed lead-acid gel-cell rechargeable battery. The
duration of battery time depends on the capacity of the battery (see chart below). The unit incorporates circuitry to maintain the proper
charge for a 12V gel-cell battery whenever the power supply is
plugged in. The unit also includes special circuitry to prevent the
battery from being damaged in the event of an extended power out
age. The battery should provide approximately 5 years of service
before needing replacement.

Figure 5: Battery connection
The battery is considered low at 12.0V and the Battery LED will
blink at this voltage level. If main power is less than 7.0V and the
battery voltage reaches 11V, the battery LED will go out and the
unit will go into hibernation mode (a low-power mode in which the
unit shuts down). The unit will return to its regular operating mode
when either the main power is restored or the battery voltage rises
above 11.5V. If the battery voltage continues to fall below 10.5V, the
unit will disconnect the battery to prevent deep discharge damage to
the battery. The unit will not reconnect the battery until the battery
voltage rises above 12.5V.
Grounding
Connect a #14AWG copper wire to the earth ground terminal
(marked “EG”) on the left end of the terminal strip and connect the
other end to a ground rod or metal cold water pipe (See Figure 6). It
is extremely important that the earth ground connection be as short
as possible. The ground rod should have sufficient depth to provide
a low impedance connection to earth. This connection is required
for the surge/lightning protection circuits to function properly.
27
Page 28
Skymetry WTU-14 Manual
NOTE: Proper earth grounding of the Skymetry
WTU-14 is required for warranty coverage.
Ground rods can typically be found at local electrical supply houses
and/or hardware stores. You MUST contact your state “Call before
you dig” hotline at least two days before you install your ground
rod, to insure that it is safe to install the ground rod in a chosen
area.
Figure 6: Grounding the Skymetry
Wiring Sensors to Dry Contact Inputs
The WTU-14 has 8 Dry Contact inputs that can be used to monitor Normally Open (N.O.) or Normally Closed (N.C.) sensors. In
addition, they can also be used for pulse counting and equipment
run-time accumulation. When used for pulse count or run time
functions, the unit will count the pulse (or accumulate time) when
the input changes to the opposite of its normal state.
Dry contact sensors are wired to the terminals labeled D1 through
D8. The corresponding Ground terminals are located on the lower
level terminal strip. The input type is programmed within the
Skymetry Software.
WARNING: Do not use sensors, switches, or relays
that supply any voltage or current to the Skymetry
WTU-14.
28
Page 29
Chapter 2: Installation
Figure 7: Sensor connected to a dry contact input]
Any N.O. or N.C. sensor can be attached to the WTU-14 using 18–
24 gauge wire. For distances of 1000' or more, use heavier gauge
wire. When running wire outdoors it is recommended that shielded
cable be used. Connect the shield to a good earth ground or metallic
cold water pipe. The total resistance of the circuit cannot be greater
than 100 ohms. Use wire appropriate for the application. See the
wire length recommendations, later in this chapter.
The WTU-14 may have more than one sensor connected to the same
terminal, however, the normal condition for each sensor on the same
terminal must be identical (either all N.O. or all N.C.).
Normally Closed Sensors
To wire more than one normally closed sensor on one input, they
must be connected in series. Connect a lead from the first sensor to
one of the Dry Contact Inputs on the terminal strip. Next, take the
other lead from the first sensor and connect it to one lead from the
next sensor. Continue connecting sensors end-to-end until you have
connected all of your sensors. Take the second lead from your last
sensor and connect it to the ground screw on the WTU-14 terminal
strip. See Figure 8.
Multiple N.C. inputs are typically magnetic reed switches to moni
tor the security of windows and doors.

Normally Open Sensors
To wire several normally open sensors to one Dry Contact input,
connect them in parallel. To do this, take one lead from each sen
sor and attach it one of the Dry Contact Input terminals. Then take
the second lead from each sensor and attach it to the corresponding
ground terminal. See Figure 9.

Wiring Sensors to Analog Inputs
The WTU-14 has 6 Analog inputs that can be used to monitor 10K
Thermistors (temperature) or 4–20mA transducers. Analog trans
ducers are wired to the terminals labeled A1 through A6. The cor
responding Ground terminals are located on the lower level terminal
strip. The input must be configured by setting the corresponding
jumper in either the Temperature or 4–20mA position. See figure
below:
Figure 10: Input A2 configured for temp, A3 configured for 4-20mA
-
-
Temperature: The unit will accept 10K thermistors. These should be
wired to an Analog Input terminal and the adjacent ground termi
nal. For compatible thermistors check the accessory list or thermis
-
tor data in the appendices. 10K Thermistor temperature range: -60ºF
to 175ºF (-51ºC to 79ºC).
4–20mA: A 4–20mA transducer requires you to have an external
DC power supply for the transducer. Connect the positive wire of
your transducer to the positive terminal of your DC power supply.
Connect the negative terminal of the transducer to an Analog Input
terminal on the Skymetry WTU-14. Connect the negative terminal
from your power supply to the adjacent ground terminal on the
WTU-14.

Chapter 2: Installation
Wiring Recommendations
The Skymetry WTU-14 will work fine in indoor environments
using unshielded cable. When wiring will be subject to long lengths
(>100') or if run outdoors, it is highly recommended that shielded
cable be used and that the shield be connected to an earth ground.
This is particularly important for sensor wires that are run in con
duit with other noise-generating conductors, such as 60Hz AC. It is
strongly recommended that input wiring be run in a conduit separat
ed from AC power or output wiring. When wire runs are long or are
in close proximity to large power consuming, power generating, or
power switching equipment, it is highly recommended that shielded
wire be used.
-
-
Also, be sure to use the appropriate gauge wire based on the dis
tance and sensor type. See chart below:

Chapter 4: Input Programming
The Skymetry WTU-14 features 8 dry contact inputs and 6 analog inputs. The analog inputs are configurable as temperature or
4–20mA. The contact inputs can be used with Normally Open (NO)
or Normally Closed (NC) sensors. The analog inputs can be used
with 10K thermistors for temperature monitoring (available from
Phonetics) or any 4–20 mA transducer. The monitored temperature
range is -60° to 175° F (-51° to 79° C). Programmable table values
can be entered when using 4–20mA transducers to scale the reading
to the appropriate units of measure.
Note: It is highly recommended that if you make
any programming changes locally (at the unit via
the serial port) after your web page has been initial
ized, that you click the Programming Refresh Link
on the web page soon thereafter. This is to ensure
that the information you are viewing on the web
page is up to date. This will also ensure that the
alarm log information displayed on the web page is
accurate.
-
Alarm States
Each Dry Contact or Analog input is monitored based on the programming parameters that define the input type and the alarm limits
for each input. Based on this programming all inputs will always
be in one of four Alarm States: Normal, Alarm, Unacknowledged
Alarm, or Normal-Unacknowledged. Each of these alarm states is
defined below:
Normal” alarm state means that an input is either:
A “
a) Within the programmed alarm limits.
b) A Normally Open input is open, or a Normally Closed input is
closed.
c) An input is beyond its limits or is opposite of its pro
grammed normality, but has not yet met its programmed alarm

An input that is in an “Alarm” state means that:
a) The selected input is currently beyond its programmed alarm
limits or is opposite of its programmed normality.
b) The selected input has exceeded the programmed recognition
time.
c) The alarm has been acknowledged.
An input that is in an “Unacknowledged Alarm” state means that:
a) The selected input is currently beyond its programmed alarm
limits or is opposite of its programmed normality.
b) The selected input has exceeded the programmed recognition
time.
c) The alarm has not been acknowledged.
An input that is in a “
Normal but Unacknowledged” state means
that:
a) The selected input is within its programmed alarm limits.
b) A Normally Open input is open, or a Normally Closed input is
closed.
c) A prior alarm on the selected input has not yet been acknowl
edged.
Dry Contact Inputs
The 8 dry contact inputs can be programmed for normally open
(NO) or normally closed (NC) operation. In addition, you can have
the Skymetry WTU-14 count the number of times the input changes
state (pulse count) and maintain the amount of time that the input is
in the opposite state (Run Time). Click on the Dry Contact Tab to
display the main status screen.

nized as an alarm. Once an alarm trips, the unit will begin its notification sequence (unless you are online through the serial port, in
which case you can acknowledge the alarm directly and cancel the
notification process). Listed below are definitions for each of the
parameters for programming the dry contact inputs.
Configuring the Input Name
The input Name is used to describe the condition being monitored.
It can be up to 16 characters.
Input Enable/Disable
A channel must be Enabled for the input to be read by the WTU-14.
When a channel is enabled its status will appear on the status screen
and on the web page.
Configuring the Input Type
The input Type can be either Normally Open or Normally Closed.
When an input changes from its normal condition to the opposite
condition, the Pulse Count (if enabled) will increment, the Run
Timer (if enabled) will start running, and the Alarm Recognition
timer will start running (if alarms are enabled).
Configuring the Run Timer
The Run Timer can be used to track how long an input condition has
existed. This can be useful for monitoring pump or generator run
times. The value can be preset by clicking on the run time value on
the lower right part of the screen.
Configuring the Pulse Counter
The Pulse Counter can be used to track how many times a contact
closure has changed state. Other possibilities include: measuring
rainfall from a tipping bucket rain gauge or measuring liquid flow
from a pulsed output flow gauge. The maximum value of the Pulse
Counter (after the multiplier is applied) is 2 billion. Minimum Pulse
Width for Pulse Count: 50ms.
The Pulse Count Multiplier allows you to make each pulse equate to
a greater value. For example, suppose a flow gauge outputs a single
pulse for every 100 gallons. By setting the Pulse Count Multiplier
42
Page 43
Chapter 4: Input Programming
to 100 the Pulse Count value now becomes the actual total number
of gallons measured by the gauge. The range of values for the Pulse
Count Multiplier is 1 to 65,535.
Alarm Enable/Disable
The Enable Alarms checkbox activates the alarm processing func-
tions for the selected channel. When the input exceeds the the pro
grammed alarm limits and exceeds the programmed recognition
time the notification process begins.
-
Alarm on Return-to-Normal
The Skymetry WTU-14 has the capability to notify you when an
input (that had previously gone into alarm) returns to normal. When
checked, Alarm on Return-to-Normal initiates this notification.
Alarm Recognition Time
The Recognition Time is the time required for a fault condition to
qualify as an alarm event. The sensor/channel must remain beyond
the limits or in a fault condition continuously for this entire period
of time in order to become an alarm. The range of values is 0–
32,767 seconds.
Alarm Reset Time
The Reset Time is the time allowed for an acknowledged alarm’s
fault condition to be corrected before the Skymetry WTU-14 resets
(reactivates) the alarm and begins the message delivery process all
over again. The minimum reset time is 30 minutes, the maximum is
32,767 minutes.
Analog Inputs
The 6 analog inputs can be programmed for 10K thermistor (temperature in degrees Fahrenheit or Celsius) or 4–20mA transducer.
The Skymetry WTU-14 will maintain the minimum and maximum
values reached for each channel. When 4–20mA is selected you
can enter table low and high values to correlate the 4mA and 20mA
signals to actual values for your application. Click on the Analog
Inputs Tab to display the main status screen.

from the pulldown menu.
Setting Table Limits
When 4–20mA is selected, you can enter table low and high values
to correlate the 4mA and 20mA signals to actual values for your
application. For example, suppose you’re using a 4–20mA transduc
er to measure the depth of water in a 15 foot well. Simply enter a
Table Low value of 0 and a Table High value of 15 and the WTU-14
will scale the input to read between 0 and 15 feet.

Calibration
To compensate for minor variances in sensor accuracy, an offset
may be programmed for each analog input. For example, if the
above input were sensing temperature and was reading 3 degrees too
low, then the calibration would be set at 3 as shown above, to obtain
an accurate reading. Only Analog-type inputs can be
calibrated.

Chapter 5: Output Programming
Chapter 5: Output Programming
The Skymetry WTU-14 has two relay outputs capable of switching
up to 0.3A at 120VAC, or 1.0A at 24VDC. The outputs can be con
trolled in a number of ways both automatically and manually. Some
examples are listed below:
n Each relay can be manually turned on or off through the PC
software or via the WTU-14 web page.
n Either relay can be set to turn on when a particular alarm
occurs.
n Either relay can be set to turn on when any alarm occurs.
n Either relay can be set to turn on when any digital or any analog
alarm occurs.
n One or both relays can be programmed to operate in pump con-
trol mode (simplex/duplex) for fill or drain applications.
-
n A relay can be controlled automatically based on Dry Contact
or Analog input values using greater-than, less-than, or equal-to
statements (See Chapter 7: Machine-to-Machine Control).
n A relay may also be controlled by another Skymetry unit using
machine-to-machine control. This allows the Skymetry WTU-14
to be used for distant pump/well control applications.

Chapter 6: Pump Control
Chapter 6: Pump Control
The Skymetry WTU-14 can be used in Fill or Drain pump control
applications using either float switches or an analog level transduc
er. When used with Float Switches, dry contact inputs #6-8 have a
dedicated special function (see below):
Pump Control using Float Switches
Dry Contact Input #6 – Lead pump float switch
Dry Contact Input #7 – Lag pump float switch
Dry Contact Input #8 – Pumps-off float switch
When performing pump control using an analog level transducer
(4–20mA), analog input #6 is designated as the well level input.
Note: Only normally-open float switches can be
used for pump control (e.g. the switch is open when
no water is present).
-
How it works—Float Switches
When performing drain pump control using float switches, three
floats are required: Lead, Lag, and Pumps-Off (see Fig 1). The Lead
float determines when to turn on the first pump. If the f irst pump
is unable to bring the level below the Pumps-Off float, then the Lag
float will close, turning on the second pump. When the level drops
below the Pumps-Off float, both pumps are turned off. If any of
the floats get stuck (i.e. the lead and pumps-off floats closed, or the
lag and pumps-off floats closed) then both pumps will be turned on
and an alarm will be tripped on the output or outputs in question. In
duplex mode, the WTU-14 will automatically alternate between the
two pumps to facilitate uniform run time between the two.
If only one relay output is set to pump-control mode, then simplex
control is performed. In Simplex mode only the Lead float (Dry
Contact #6) and Pumps-Off float (Dry Contact #8) are required.
Either output relay can be used in simplex mode.
53
Page 54
Skymetry WTU-14 Manual
Figure 1: Float positions for a drain application
In a Fill application, the Lag and Pumps-Off floats would change
position as shown below:
Fig 2. Float positions for a Fill application
In this case, the pumps are attempting to keep the well full. When
the well is full all three floats are closed. If the level drops below
the Lead float, then the first pump will turn on. If the level rises
above the Pumps-Off float then the pump will turn off. If the level
continues to fall below the Lag float, then the 2nd pump will turn
on. Both pumps will remain on until the Pumps-Off float closes.
54
Page 55
Chapter 6: Pump Control
If only one relay output is set to pump-control mode, then simplex
control is performed. In Simplex mode only the Lead float (Dry
Contact #6) and Pumps-Off float (Dry Contact #8) are required.
Either output relay can be used in simplex mode.
How it works—Analog Level Sensor
When performing pump control with an analog level sensor, the
Lead, Lag, and Pumps-Off levels are programmed into the Skymetry
software. The unit then measures the actual level on Analog Input
#6 and turns on the appropriate relay outputs. If both outputs are
set to Pump Control mode, then alternating duplex control will be
performed. If only one output is set, then Simplex control will be
performed. The analog level sensor must be a 4–20mA transducer
that is selected and calibrated based on the depth of the well. The
specified output of the transducer must be entered into the Table
Range settings for Analog Input #6.
Installation Recommendations
Be sure to install and wire the Skymetry WTU-14 and associated equipment in accordance with all local codes and regulations.
Adhere to Standard Practice/Best Practice policies when installing
and wiring any control system. Be sure to include hand-operated
switches to disconnect power on all pumps/equipment to insure
worker safety when installing and servicing equipment.
Programming for Pump Control
To program the unit for Pump Control, click on the Outputs tab.

Chapter 6: Pump Control
For test purposes you may wish to use hand operated switches to
manually control the pumps and simply watch the system LEDs
to see if the Skymetry WTU-14 is functioning properly. If you are
using “duplex” pump control, select the other output and set it for
Pump Control mode also. After verifying that the unit is function
ing properly, move your hand-operated pump switches to “Auto”
and verify that the WTU-14 is properly controlling the system.
Output Wiring
The output relays on the Skymetry WTU-14 are for low current
control signals (0.3A 120VAC/1.0A 24VDC maximum).
DO NOT directly connect the power for the pumps to these relays—
THIS WILL PERMANENTLY DAMAGE THE WTU-14.
Use the WTU-14 outputs to control intermediate motor contactors/
relays that will switch actual power to the pumps.

Chapter 7: Machine-to-Machine Control
The Machine-to-Machine Control feature allows you to control outputs of other Skymetry WTU-14 units (or outputs within the same
unit) based on input conditions. For example, you can switch an out
put on a WTU-14 unit several miles away if an input on a different
unit is greater than a specified value. The output being controlled
must be set to manual mode. Up to 8 machine-to-machine control
events can be configured per WTU-14 unit. Note that when an input
condition causes an output to change state, a separate event must be
programmed to make the output change back. For example, if you

Click the down arrow in the Input Trigger field to select the input
that will initiate the event. If you select a Dry Contact input, you
can have the event occur when the selected input goes from Open-to-Closed or Closed-to-Open. If you select an Analog input you can
have the event occur if the input is equal-to
, greater-than, or less-
than a specified value.
Enter a value for the comparison (range: -16,384 to 16,383).
Note: peer-to-peer events are triggered as soon as
the input meets the trigger conditions. There is no
recognition time applied in this case. Also, peer-topeer events will not be executed while you are on
line locally.
Next, enter the SkyID and Password of the WTU-14 unit whose out
put you want to switch. Select the output number and action (either
ON or OFF). Click Apply or
OK when finished. Remember, the target output must be set to manual mode, otherwise the command will
be ignored. If the password is wrong the command will be ignored
as well.
Local Output Control
You can perform control logic using the same inputs and outputs on
a single WTU-14 unit. If you want to switch an output on the same
Skymetry WTU-14 as the input, then simply enter the unit’s own
SkyID (a password is not required in this case). The output must be
set to manual mode. Local output control does not use any airtime
and also executes instantly (as long as there are no preceding peer-topeer events that must communicate with a different WTU-14 device).

Important Information and Warnings
=It may take several minutes for the peer-to-peer command to
reach the destination Skymetry WTU-14.
=Peer-to-peer commands are processed in a sequential, non-pre-
determined order. This means that if more than one command
is triggered, the subsequent commands must wait until the cur
rently processed command is finished. If two peer-to-peer com
mands are triggered simultaneously that affect the same output,
the order of the processing cannot be guaranteed.
=Both the source and destination WTU-14 devices must be pow-
ered on and operational for peer-to-peer commands to operate
correctly.
=If the unit is in the middle of alarm processing, peer-to-peer
commands may be delayed while alarms are being sent.
=Peer-to-peer commands are not processed while logged in with
the PC software. The user should log off and the serial cable
should be unplugged during normal operation to ensure that
peer-to-peer commands are properly processed.
-
-
=Setting peer-to-peer trigger values too close can cause output
oscillations. Peer-to-peer commands are an advanced feature
and should be well thought out. Do not use them for critical
applications where the risk is unacceptable.
=All peer-to-peer control actions will use a wireless message
packet.
Sample Application
Suppose you had a well and a pump which were several miles apart.
When the pump runs, it fills the well. Your goal is to maintain a
certain level in the well. If you place one WTU-14 unit at each loca
tion you can have two peer-to-peer events accomplish your goal. In
addition, you can use the WTU-14 inputs to monitor other key items
such as:
• well level too low
• well level too high
-

Skymetry WTU-14 Manual
• pump failure
• power failure
• generator on
• temperature
Figure 3: Well and Pump Control via Machine-to-Machine Commands
Let's suppose the well level is 25' and you need to maintain the
level between 5' and 20'. The first thing you would need is a level
transducer in the well. Next, program your two machine-to-machine
events into the WTU-14 located at the well. The first would be to
turn ON the pump if the level is Less-Than 5'. The second event
would be to turn the pump OFF if the level is Greater-Than 20'.
Consider the rate at which the well fills when the pump is running,
in order to account for the machine-to-machine command delay
time between the WTU-14 units. Also note that machine-to-machine
control is completely independent of alarm processing, so you can
also trip high or low-level alarms based on the well level.

Chapter 8: Notification
Chapter 8: Alarm Notification
The Skymetry WTU-14 can deliver alarm message notif ications
by voice phone call, internet e-mail, and text messaging to various
messaging devices and cell phones. A total of 24 notification desti
nations can be programmed to be contacted in the event of an alarm.
The unit also lets you to set an escalation level for each destination,
allowing you to have a group of people contacted f irst (tier 1) and,
if the alarm is not acknowledged, a second group of people (tier 2)
contacted. You can program up to 24 tier levels of destinations and
include a programmable delay time between each tier.
How does notification work
Once an alarm occurs, the Skymetry will begin sending its alarm
message to the programmed destinations. The unit will start with
destinations at tier 1. Once the Tier Delay expires, the unit will start
sending alarm messages to destinations in the next tier. The Tier Delay time begins as soon as the alarm occurs, so if it were programmed to 60 minutes, the next tier would start receiving alarm
messages one hour after the alarm occurred. The Skymetry will
send its alarm message to each destination until it receives acknowl
edgment, or it will automatically acknowledge the alarm after all
destinations have been sent the message or when the last tier delay
time has expired.
-
-
Note: If you are logged in through the serial port, no alarms
will be sent until you log off and disconnect the serial cable. If
you acknowledge the alarm through the software before logging
off, no alarm messages will be sent. This can be useful for per
forming on-site maintenance or testing the system. If you are
not logged on through the serial port the alarm messages will be
sent immediately, one at a time.

Voice Phone Call
The WTU-14 can send alarm messages via a voice telephone call.
It does this without having a telephone line connected to the unit.
When an alarm message is sent as a voice call the number is dialed
from the Skymetry Messaging Service Center. The message is spo
ken from a computer that will customize the message based on the

The alarm from the Skymetry WTU-14 can be acknowledged by
replying to the alarm message that was sent to you. As long as you
received the message on a two-way data device, you can simply
reply back to send your acknowledgment. In the reply message,
just enter the alarm ID number in the message. For example, if the
alarm ID number was 1720, then you would reply with a “1720” in
your reply message to indicate to the WTU-14 that you received and
acknowledged the alarm message. A sample acknowledgment mes
sage is shown below:
If another alarm occurs while the unit is delivering messages for a
previous alarm, the second alarm will be handled after the first is
acknowledged.
You can use tier escalation to organize the destination delivery. Set
each destination to its own tier level and set the delay to two min
utes. In this case a new message will be sent every two minutes to
the next tier level.
Rearranging the destination order can be done simply by changing
the Tier Levels.

Chapter 9: Operation
Chapter 9: Operation
After installation and programming have been completed, the
Skymetry WTU-14 is fully operational. This chapter explains how
the WTU-14 operates.
PART ONE: Alarm Notification and Acknowledgment
There are 3 stages to a complete alarm event: 1) Alarm Recognition,
2) Alarm Notification, and 3) Acknowledgment.
Note that not all fault conditions will go through each stage. For
example, some may not meet the recognition time.
Alarm Recognition
1) The WTU-14 monitors 8 dry contact inputs, 6 analog inputs,
main power, and battery backup. When the status of an input
changes or exceeds user-programmed limits, it causes a fault
condition.
2) If the fault condition lasts long enough to meet its programmed
recognition time, the fault condition becomes an alarm and the
WTU-14 begins the alarm notification sequence.
Alarm Notification
The WTU-14 can send alarms via Voice phone call, E-mail,
Alphanumeric pager, or Text message to wireless (cell) phone.
Dialout Note: Call Progress
The Skymetry WTU-14 monitors call progress when dialing out
in voice mode. If it dials out and encounters a busy signal or no
answer it will wait about a minute and try again up to 3 times. If the
call is answered by an answering machine or voice mail system the
alarm message will likely not be recorded because it will be speak
ing while your greeting message is playing. Note that since the call
was actually answered, the WTU-14 will consider the call completed
and not dial it again.
-
75
Page 76
Skymetry WTU-14 Manual
Alarm Notification—Voice
When dialing out to a destination programmed as “voice,” the
Skymetry WTU-14 waits for the phone to be answered, then recites
its identification message, then the message identifying the input
that has gone into alarm.
Below is an example of what the WTU-14 would say during a typi
cal ‘voice’ notification:
“Hello, Sensaphone Inc. has a message for ‘Dave’ <destination name>.”
“To accept the message press 1.”
“To cancel the message press 2.”
{press 1 to hear the alarm message}
“Skymetry alarm at 'Oak Station' <unit name>, SkyID number ‘1123350’
<skyid>.”
“Contact 1, ‘Security’ <input name> is in alarm.”
“To acknowledge, send 1201
“End of message”
“To replay message, press the * key.”
“To reply to the message, press 2.”
“To end this call, press 3.”
<alarm ID>”
Alarm Notification—E-mail
When sending an alarm message via e-mail the WTU-14 will compose a text message based on the Unit's name, SkyID, Input name,
Input type, current value, and alarm limit (where applicable). A
sample alarm message is shown below:
Contact ALARM at Oak Station Sky ID#1123350
Contact 1 Security is in alarm
To acknowledge send 1202

Alarm Notification—Alphanumeric Pager
When sending an alarm message to an Alphanumeric pager, the
WTU-14 leaves a text message on the display of the pager. A sam
ple is shown below:
High 4–20mA ALARM at Oak Station Sky ID#1123361
Analog 1 Water level is now 21

-
Tier Delay
You can group destinations into tiers and then program a delay
time until the next tier gets called. This allows you to contact your
primary personnel first and, if necessary, escalate the calling to the
next level. Up to 24 tiers can be configured. The WTU-14 will start
sending alarm messages to all destinations programmed in Tier 1.
If the alarm is acknowledged, it will halt the notification process for
that alarm and no additional alarm messages will be delivered. If all
of the Tier 1 destinations have been sent the alarm message and no
acknowledgement was received, the unit will wait the programmed
Tier Delay Time and then start sending the alarm to the destinations
in the next Tier. An example is described below:
Chuck Janet Morton
Mary George Zach
Sue Ron Tony
Derek Jason
Dave Carmen
Tier Delay Time: 60 minutes
An alarm occurs at 8:00
PM
The Skymetry WTU-14 starts sending alarm messages to members
of Tier 1.
No one acknowledges the alarm.
At 9:00
PM the Tier delay has expired and the unit begins to send
alarm messages to members of Tier 2.
At 9:30
PM the WTU-14 receives an acknowledgement message and
the unit stops the notification process.
The people in Tier 3 do not get contacted.
Alarm Acknowledgment
Acknowledging an alarm will halt the alarm notification process.
Voice notification alarms must be acknowledged during the original
phone call. E-mail, Alphanumeric pager, and Cell phone alarms can
be acknowledged by replying back to the original alarm message or
by sending the unit a message with the alarm ID number. The sec
tions below detail the procedure to acknowledge an alarm.
Alarm Acknowledgment—Voice Notification
“Hello, Sensaphone Inc. has a message for 'Dave' <destination name>.”
“To accept the message press 1.”
“To cancel the message press 2.”
{press 1 to hear the alarm message}
“Skymetry alarm at 'Oak Station' <unit name>, SkyID number '1123350'
<skyid>.”
“Contact 1, 'Security' <input name> is in alarm.”
“To acknowledge send 1101
“End of message”
<alarm ID>”
-
78
Page 79
Chapter 9: Operation
“To replay message, press the * key.”
“To reply to the message, press 2.”
“To end this call, press 3.”
To acknowledge the alarm you must press “2” (reply to the message). Next, enter the four digit alarm ID that was spoken at the
end of the message followed by the “#” key. When prompted to send
the message, enter the “#” key again. The WTU-14 will respond by
saying: “Alarm sent.” The alarm has been acknowledged and the
notification process stops. If the Touch-Tone acknowledgment code
is not received, the Skymetry WTU-14 will continue to send alarm
messages to the remaining destinations.
Note: An alarm cannot be acknowledged using a
pulse (rotary) telephone.
Alarm Acknowledgment—Alphanumeric Pager
When sending an alarm message to an Alphanumeric pager, the
WTU-14 leaves a text message on the display of the pager. If you
have a two-way alphanumeric pager you can acknowledge the alarm
by replying to the original message with the alarm ID number,
which will acknowledge the alarm. For example, if the alarm ID
was 1503, you would simply reply back with “1503.” If you do not
have a two-way pager then you can send the WTU-14 an e-mail
using either a computer or a cell phone. The e-mail address of your
Skymetry WTU-14 is[email protected], where you would
substitute the word skyID with your SkyID number. In the message
area simply send the unit the alarm ID number.
Alarm Acknowledgment—Text Message to Cell Phone
When sending an alarm message to a cell phone, the WTU-14
leaves a text message on the display of the phone. You can acknowl
edge the alarm by sending a reply back to the WTU-14 with the
alarm ID number, which will acknowledge the alarm. For example,
if your alarm ID number was 1107, you would simply reply back
with “1107.” Alternatively you can send the WTU-14 an e-mail
using a computer. The e-mail address of your Skymetry WTU-14
is[email protected], where you would substitute the word
skyID with your SkyID number. In the message area simply send
the the alarm ID number.

PART TWO: Status Request
You can request a status report from your WTU-14 by sending it a
command via e-mail. When the unit receives the command it will
assemble a status report and send it back to the originating e-mail
address. Only inputs that are enabled will be included in the report.
If alarm monitoring is not enabled for a particular input, its status
will be displayed as disabled. To request the status report you need
the unit’s password and skyID. The e-mail format to request a status
report is shown below:

Chapter 10: Web Page
Chapter 10: Skymetry Web Page
The Skymetry Web Page is where you can check status, monitor
data message usage, make programming changes, and even control
outputs from any internet connected computer. In order for your
unit to be accessible via the web page you must first change the
password in your unit and then log out. This will instruct the unit
to register with the Skymetry web server, setup an account for your
unit, and perform a Full Programming Update. Note that it may
take 1 to 2 hours for the web server to receive all of the program
ming information from your Skymetry WTU-14. Do not make any
programming changes to your unit during this period. This initial
Full Update will occur automatically and is included in your activa
tion fee and does not count toward your monthly allowance.
Once the Skymetry web server has finished receiving the updates
from your unit you can go to www.skymetry.com, enter your SkyID
and Password, and click Login. The web page for your Skymetry
WTU-14 will be displayed. The web page presents a view of the
system which is very similar to the Skymetry PC Software, except
for the fact that it is a snapshot of information from a specific point
in time—it is not updating in real-time. To retrieve the latest values
you must click either the Status Refresh or Programming Refresh
links.
-
-
Note: It is highly recommended that if at any
time you make any programming changes locally
(at the unit via the serial port) that you click the
Programming Refresh link on the web page soon
thereafter, to ensure that the information you are
viewing is up to date. This will also ensure that the
alarm history information will also be accurate.
Status Refresh
You can retrieve the latest input and output values by clicking
the Status Refresh link. This will send a message to the WTU-14
requesting the latest input and output status information. When
83
Page 84
Skymetry WTU-14 Manual
the unit receives the request it will immediately send back a reply.
During this waiting period the web page will display the input and
output values in green italics until the updated information returns.
At the bottom of the screen is a time-stamp which indicates the date
and time of the last update. Note that clicking the Status Refresh
will use 5 to 7 data messages, depending on the amount of data
transferred. You can minimize the number of data messages by dis
abling any inputs which are not being used.
Programming Refresh
The Programming Refresh command will refresh all Skymetry
WTU-14 programming as well as input/output status. The first
Programming Refresh is included as part of the activation fee and
will not increment the data message counter nor be applied to your
monthly allowance. You only need to click this button if you believe
that programming changes may have occurred locally, at the unit,
and you want to refresh the information on the web server.
Programming via the Web Page
-
You can change any parameter in your WTU-14 from the web page,
just as you would using the Skymetry PC Software. All program
mable items will appear as Blue links. For the inputs you can click
on any item for that channel and the respective programming screen
will appear. If you change an item and click OK, the change will be
sent to your unit. This will take a few minutes to process. Similarly
you can change Output programming, Notification programming,
and Machine-to-machine programming.
Switching Outputs via the Web page
To switch an output, Login to the web page and click Outputs.
Next, click on the Output number you want to switch. On the pro
gramming screen, locate the State field and select On or Off, then
click OK. The command to switch the output will be sent to your
unit. Note that this may take 1–2 minutes.

Account Usage
The main status screen displays an Account History containing the
number of data messages used for the month as well as historical
usage. Data messages are those used during a wireless data transfer
to or from the unit. They are sent whenever an alarm is delivered,
a machine-to-machine command is sent, programming changes
are made, or if the Status Refresh/Programming Refresh links are
clicked. The number of data messages used per transaction varies
depending on the type of transaction and the programming param
eters within the unit. Some typical values are listed below:
Transaction Description Data Messages
Status Refresh 5–7
Programming Refresh 9–115
Machine-to-machine command 1
Voice Alarm 2–4
E-mail alarm 1–3
-
Alarm message to web server 1
Programming change (1 item) 2
E-mailed Status via GST command 2–7
Alarm History
An alarm history log is available on the web page to provide details
on alarms that have occurred and whom acknowledged them. The
log can be queried by entering a start and end date range, or by
selecting one of the QuickDates options. You must have the Send alarm events to the server option enabled in order for the alarm
events to appear on the web page. This option is configured on the
Notification programming screen. Note that the time stamps appear
ing on the web page do not indicate when the alarm occurred, but
rather the time that they were received by the web server.

Chapter 11: Testing
Chapter 11: Testing the Skymetry WTU-14
It is extremely important that you test the system after installation
to make sure that it is working properly and that all programming is
correct. In addition, it is highly recommended that you test and/or
verify proper operation on a weekly basis to ensure that the system
continues to function as required. (See Appendix A.) The following
items should be tested:
• Notification to all destinations to make sure that each one is pro
grammed correctly and that the messages are actually delivered.
• Input testing to make sure that the system is reading them cor
rectly and that when a fault occurs the system responds appro
priately.
• Output testing to make sure they are wired correctly and that
they switch on and off when instructed.
• Control programming—Local control, Machine-to-machine,
or Pump control—to make sure that the system is functioning
properly, as required for your application.
Notification Testing
Create an alarm and confirm that all destinations receive the alarm
message. This can be done by forcing an input into alarm, by
temporarily adjusting an alarm limit, or by changing the normality
of a Dry Contact input. The Alarm LED on the front of the unit will
begin blinking when an alarm has occurred. Be sure to disconnect
from the serial port after creating the alarm, otherwise the
notifications will not be sent. After confirming that all notification
messages were delivered, correct the alarm condition and/or adjust
your programming as required.
-
-
-
Input Testing
Check the current value of all of the programmed Dry Contact
and Analog Inputs. Make sure that the values being displayed are
correct.
87
Page 88
Skymetry WTU-14 Manual
For Dry Contact inputs, momentarily reverse the input condition
to verify that the unit recognizes the change of state. For example,
if you have a normally open sensor connected to Dry Contact #1,
force that sensor closed and verify that the unit displays the value as
closed.
For analog inputs, verify that the input reading matches the entity
being measured. For example, for temperature inputs confirm that
the unit is reporting the correct temperature.
For 4–20mA inputs, confirm that the level or value being displayed
in the WTU-14 matches the actual conditions being measured.
Output Testing
Confirm that the power limitations of the outputs will not be
exceeded. The WTU-14 outputs are rated for a maximum of 0.3A
at 120VAC or 1.0A at 24VDC. Test the outputs by switching them
on and off manually and confirming that the device being controlled
turns on and off. The Output LEDs on the front of the unit should
also turn on and off.
Control Programming
For applications that utilize control programming it is important
to test all scenarios that may affect system operation. This means
you should test your system under normal operating conditions as
well as abnormal (or failure) conditions to make sure that you have
designed your system to operate under the worst-case scenario.
Note that Local and Machine-to-Machine control will not execute
while you are connected locally.
To test Local control operation, force input conditions as necessary
to activate the output(s). Confirm that the input-to-output control
logic is executing properly. Test each programmed control algorithm
separately to make sure that each one is functioning as desired.
To test Machine-to-Machine control, force input conditions as nec
essary to activate the output(s) on your remote WTU-14 device(s).
Confirm that the outputs on the remote unit(s) have turned on or off
as instructed. Test each programmed control algorithm separately
88
-
Page 89
Chapter 11: Testing
to make sure they are all functioning. Have the system go through
a complete automated control cycle of your system to confirm that
the unit and its programming are operating as intended.
Pump Control
To test Pump Control using float switches, force the float switch
inputs open or closed as necessary, to make the output(s) turn on
or off. In a Drain application the first pump would turn on if the
Pumps-Off and Lead float switches were closed. The second pump
would turn on if the Lag float switch also closed. Both pumps
would then turn off when all three float switches opened. In a fill
application, the first pump would turn on when the Pumps-Off and
Lead floats opened. The second pump would turn on when the Lag
float also opens. Both Pumps would turn off when all three floats
closed.
To test Pump Control using a level transducer you can temporar
ily force the input level to a certain value by adjusting the calibra
-
tion for the Analog Input. In a drain application, force the input to
be above the Lead level and the first pump should turn on. If you
then set the input above the Lag level, the second pump should also
turn on. Setting the input below the Pumps-Off setting will turn
both pumps off. In a fill application, setting the input below the
lead level will turn the first pump on. Setting the input below the
Lag level will turn on the second pump. Setting the input above the
pumps-Off level will turn off both pumps.
Once you have confirmed that the WTU-14 is controlling the sys
tem properly, allow the system to operate automatically. Observe a
complete Drain or Fill cycle and verify that the system is operating
as required.

APPENDIX A: Checking Your Skymetry WTU-14
for Proper Operation
We recommend that you test your Skymetry WTU-14 weekly to be
sure it is functioning properly. This will ensure that when a problem
arises the Skymetry WTU-14 will be ready to alert the appropriate
personnel. A blank Test Log is included at the back of this manual.
There are several tests to be performed:
1. Request a Status Report from the unit by sending it an e-mail
message and verifying the reply. This will test the unit’s ability to
receive and send a message. It will also verify that all of the inputs
are reading properly, the alarm conditions are OK, the electricity is
on, and the battery is OK.
2. Create an alarm on each input by tripping all connected sensors.
This will verify that each input is being recognized by the unit and
that it is programmed properly.
Temperature sensors: Heat or cool the sensor.
Motion sensors: Have someone walk in front of the sensor.
Door and window sensors: Open the door or window.
Water sensors: Apply a small amount of water beneath the sensor
or use a wet towel and touch it to the sensor probes.
Humidity sensors: Raise the humidity around the sensor by hold
ing a cup of very hot water beneath it.
4–20mA Transducers: Verify that the WTU-14 is reading the prop
er level by measuring the monitored quantity using alternative
methods.
Allow the unit to send its alarm message to all programmed con
tacts. This will make sure that the WTU-14 is programmed properly.
It will also prepare personnel to respond appropriately when they
receive a call from the WTU-14.

3. Test the battery by unplugging the AC adapter and making sure
that the WTU-14 continues to function. Check the LEDs to make
sure that the Power LED starts to blink and the Battery LED glows
steadily. Keep the AC adapter unplugged so that a Power Failure
alarm occurs. Allow the unit to send its alarm message to all pro
grammed contacts while running on battery backup. Plug in the AC
adapter after the unit has finished sending all of its messages.
4. If you require assistance, contact Phonetics Technical Support at

Why does the unit call people even after I acknowledged
the alarm?
• When an alarm occurs the unit will begin to sequentially broadcast all alarm messages for the first Tier. Depending on how
quickly they get dispatched from the messaging center its possi
ble for additional calls to be made even after the alarm has been
acknowledged. Once the message is received at the messaging
center it will be called regardless of acknowledgement.
