Re:
Over the past ten years, Xtel and its authorized dealers placed a large number of XtelAlert Remote Site Monitors (XTAs) at
compressor, booster, tank and well sites. Since then, many facility acquisitions and turnovers have occurred.
Your field staff may not know where to go now for sales and service on their alarm callout devices.
Xtel designed all of its upgrades to be backward compatible to the first units produced. This means that our upgrades
can bring older version XTAs up to date with better software and a lot of new value-added features. We also have a number
of integrated system configurations to reduce problems with dirty power, brownouts, surges, telephone and radio
communications. So we can modify your existing equipment to make it even more useful to you as your conditions change.
It is this flexibility that motivates companies like yours to standardize the use of our equipment at all remote facilities.
If you have XTA voice alarms at your facilities, please keep this memo for reference. If you have bought a competitor’s
unit which has a cell phone built in and you have experienced serious service difficulties, perhaps you should consider
replacing it with something more reliable and easier to service. Or perhaps you have our units but no manuals or wiring
schematics. If by chance you still use old AGT ARUs, you will be happy to know that the XTA is the modern replacement
that uses the same easy control codes. No extra or special equipment is required to run or program our equipment. And
unlike our competition, we are available on weekends, holidays and after hours as required. XTA prevents production losses!
When you have new facilities coming up, we would be happy to hear from you or your project engineers. In many
cases, we offer cost-effective alternatives to expensive, complex RTU and SCADA systems. We also have data logging and
modem capabilities in this year’s model, and some innovative wireless modem systems to give you remote tank level
monitoring.
Standard XTA Features: -40C to +50C, low current, reliable callout is what every XTA is made for.

Introducing your new XtelAlert Full Solar Remote Site Monitor Package.
Solar panel size and efficiency, battery type and size, cell phone and XTA power
draw, grounding, and antenna configuration... To ensure reliable call outs under harsh
conditions, all components have to be balanced. Here'
s why:
In - 40 ° C weather, a battery operates at 25% of
its capacity. The cell phone draws power during call
outs, and the sun may not always be shining. XTA
effectively integrates all the components so you get
payback from not oversizing batteries and solar panels.
This system has proved itself during cold Alberta winters and during
major power outages. Many users say three callouts have paid for the
entire system through reduced maintenance trips & production savings.
This robust assembly includes a
solar XTA, cell phone, data jack,
temperature compensated charge controller, 6.5 dB directional yagi
antenna, 40-watt panel, 100 AH lead acid battery, portable selfsupporting stand, brackets, clamps, fused cabling, and all the
features of a standard XTA:
* Excellent protection from lightning, surges, & static
* Call out via telephone, radio, cell phone, pager
* Trouble-free long distance dial out (each 32 digits!)
* Protected memory on dial-out numbers
* Local & remote parameter changes
* Voice label clarity - clean, crisp, human!
* Easy setup, training, & operation
* Customizable & expandable for the future
* Dependable internal battery backup
* Low maintenance, long battery life
* Thiry Two (32) call out numbers
This package can be optioned to speak ambient
temperature and the assembly's actual battery
voltage. Other new options allow you to select
from up to 9 callout lists - each with the 32 number

Is your company incurring
unnecessary production losses?
Minimize your risk of a dead cell
phone battery at call out time...
The XBC External Battery Charger Option works
with the XtelAlert  Remote Site Monitor, properly
charging and monitoring an external battery for
rock solid backup power to the XtelAlert ( XTA )
and an approved cell phone.
This option externalizes XTA'
s smart battery circuit to monitor and charge a high
capacity battery. At - 40 ° C, actual battery capacity is very critical when planning
for crucial call outs from remote locations.
The XBC option consists of a custom XTA, a standard 120 Volt wallmount transformer, a 10 Amp Hour
battery, and a cell phone. Under normal circumstances, the XTA receives its operating current from a 120 Volt
source, and it maintains the external battery at optimum charge. As soon as commercial power disappears, the
XTA draws on battery power to initiate callouts via the cell phone. XTA manages the power for the cell phone,
the battery, and itself. This particular application has proven itself with generator sets and remote booster
stations where commercial power failures threaten production & costly freeze ups.
Consider these benefits:
•
•
•
•
•
•
•
XTA will call out for at least one hour after continuous power failure in subzero temperatures
XTA will report a discharged XBC-12 battery, reducing possible downtime
Before the XBC-12 battery dies of old age, the XTA will report it, reducing your downtime and risk
Battery lifetime is maximized; battery charge is temperature compensated to - 40°° C
The battery charging circuit is XTA-protected from lightning and power surges
Cell phone power is less of a "weak link" in callout communication
When power fails, XTA monitors a GENSET, PLC, Tank Level, or Well !
Don't let - 40º or power outages cut your production ...

Xtel International Ltd. is pleased to provide this useful addition to the capabilities of its XtelAlert
(XTA) product.
Why Variable Speed Drive Monitoring? Variable speed drives (VSD) are becoming very popular
in the oil and gas industry. They provide easy and safe speed and torque control on expensive oil
pumps. Operators are able to optimize production and protect their pumps with VSDs. The XTA
enhances these capabilities by allowing alarm callout, remote monitoring and remote control of the
VSD over a telephone or cellphone. With the logging option the XTA can also provide the user
with torque and speed trends.
What is Provided…
The XTA is equipped with either an RS232 or RS485 serial interface to communicate with one or
multiple VSDs. Optional XTA logging capabilities can be provided for VSD parameter trending.
The XTA analog and binary sensor inputs can be used to monitor pressure, temperature, flow and
other local alarm sensors.
XTA VSD Interaction: The XTA acts as a Modbus master and interrogates the VSD(s) for register
values corresponding to speed, torque, current, faults, etc. These same values are logged by the
XTA for future trending if this option is equipped.
XTA User Interaction: The user can call the XTA to obtain a current status of the VSD operating
parameters (speed, torque, current, etc). The user can also use their telephone keypad to perform
VSD on, off, reversal and speed commands through the XTA. The XTA compares the incoming
Modbus register values against its alarm limits and generates a callout to the user if the values
exceed their limits.

Xtel International Ltd. is pleased to provide this useful addition to the capabilities of its XtelAlert
(XTA) product.
Why Data Logging? Many XTA users need to log their analog signals. This may be required for
safety reasons, or for optimization of processes within their facilities. Circular and linear logging
options are available on the XTA.
How it Works…
Sensor Logging: The customer specified XTA analog sensor inputs are logged into XTA nonvolatile memory in a compressed format. Logging setup includes sample rate, averaging and dead
band for each sensor. Logging can also include maximum, minimum and average over specified
intervals for any of the analog sensor inputs.
Log Alarm: The XTA can be configured to call the user when its log is nearly full. This ensures
that the user does not miss any log data. The volatile memory circular log does not generate a log
alarm.
Log Retrieval: When the sensor log needs to be retrieved, the user phones the XTA with a
modem equipped computer and a terminal program such as MicroSoft Hyperterminal. The XTA will
answer the call and start a modem connection sequence if no DTMF is entered within 30 seconds.
The XTA automatically negotiates the best data rate and uses V.42 data retransmission protocol to
remove transmission errors. The user is given a logon page. Upon successful logon the user can
navigate to the XTA log page. Downloading will begin after user selection of X-modem or 1K Xmodem and specification of a file name. The XTA will disconnect a remote modem session after
30 seconds of no activity. The user can then run the Xtel supplied file decompression routine to
generate a comma separated variable (CSV) text file that can then be opened and worked with in
any spread sheet program.
Log Reset: The user can reset and clear the XTA log from the log page. This must be done when
the log is full as the XTA will not discard previous log records when running in the linear log mode.
Local RS232 Access: The user can also access the above functions locally on the XTA using a
computer with a RS232 interface plugged into the XTA RS232 connector. The users interface is
the same as above.

Xtel International Ltd. is pleased to provide this useful addition to the capabilities of its XtelAlert
(XTA) product.
Why Modem Capabilities? XTAs are sometimes installed in very remote and hostile
environments. Many XTA users need to retrieve XTA logging records or change XTA operating
parameters of these remotely located XTAs. Xtel developed easy to use terminal software and a
robust and compliant modem option for the XTA to allow it clients remote access to their XTAs.
What is Provided…
A low temperature, low power consumption modem with North American standard Bell 103, 212
and 202S/T capabilities. This allows operation over telephone lines, cellphones and 2 way radio
systems. Terminal compatible software in the XTA allows the use of any standard PC based
terminal program.
How it Works…
Accessing the XTA:. The user phones the XTA with a modem equipped computer and the NEW
XTA Graphical User Interface (GUI). The XTA will answer the call and start a modem
connection sequence if no DTMF is entered within 30 seconds. The XTA automatically negotiates
