Introduction
The EL-SMS-2G range is a family of battery powered temperature alerts that will
sendSMS(ShortMessageService)notificationmessagestodesignatedmobile
phone numbers whenever the temperature monitored exceeds a programmed
upper or lower temperature limit.
Thetemperaturelimitsalongwithotherconfigurableparametersaresenttothe
unitviaaconfigurationSMSwhichiscreatedusingthe“ELSMS”App.
OnceconfiguredtheELSMSunitscansendperiodicsummarymessages
toconfirmthattheyarerunningnormally.Summarymessagescontainthe
minimum, maximum and average temperature since the previous summary
message, along with a history of the three most recent temperature limit breaches
that the unit has detected.
These products use the GSM (Global System for Mobile Communications) network
todelivertheSMSnotificationmessagesandmustbefittedwithamicroSIMcard
to allow them to connect to a GSM network and register. These units use a built-in
aerial to allow communication with the GSM network.
Notificationmessagescanbesenttouptothreeprogrammedmobilephone
numbers.Eachnumbercanbeindividuallyconfiguredtoreceivespecificalerts,i.e.
Alarm, Low Battery or Summary messages.
Basic Operation
SIM Card
User Guide
The units require a micro SIM card to operate. It is important that no PIN code is
enabled as this will prevent operation. If necessary, a normal mobile phone can be
used to disable the SIM PIN code lock. Be aware that the product will erase any
existing SMS messages that are already stored on the SIM card.
TheSIMcardmustbefittedtooperatenormally.
All 2G micro SIM cards should work as long as the PIN code function is disabled.
Visit http://maps.mobileworldlive.com to check for GSM coverage in your
geographic location.

EL-SMS-2G-TP / TP+ / PROBE-G USER MANUAL
Thermistor Probe
These units are supplied with a thermistor probe to sense temperature. The
EL-SMS-2G-TP is supplied by default with a Type 2 (Standard) thermistor probe.
The ELSMS2GTP+ is supplied by default with a Type A (High Accuracy) probe
and the EL-SMS-2G-PROBE-G with a Type A probe inserted into a glycol bottle.
The thermistor probes connect to the unit via the 3.5mm jack socket.
Thethermistorprobetypecanbeselectedwhentheunitisconfiguredusing
the App.
Temperature Monitoring Interval
These units will take a temperature reading every minute. For this reason it may
take up to one minute before the unit responds to a change in temperature.
Multiple SMS Destinations
Theunitscansendnotificationstoamaximumofthreemobilephonenumbers.
It should be noted that operating any unit with more than one destination mobile
phonenumberwillsignificantlyreducetheexpectedbatterylifeandmayincur
additional costs as more messages are sent.
When multiple destination numbers are used these units will attempt to send
notificationmessagestoeachphonenumber.Iftheunitisabletosuccessfully
transfer the SMS to the mobile network for at least one of the destination numbers
then it will assume that the delivery of the message was successful. Be aware
however that actual delivery of the message is reliant on the mobile network and
mobile operator’s services operating normally.
User Guide
Alarm Delay Operation
These units allow a separate pre and post alarm delay to be applied to any set
temperature alarms. This is useful to prevent sending excessive text messages if
themeasuredtemperatureisfluctuatingaroundeitherthehighorlowalarmlevels.
When a knockin delay is used, these units will wait until that number of consecutive
temperature readings have all been in an alarm condition before sending a
temperature alert message. If a knockout delay is used, they will stay in an alarm
stateuntilthespecifiednumberofconsecutivereadingsarealloutsideofanalarm
condition. When the knockout delay has completed, they will once again respond
to new alarm conditions when they occur.
If the alarm delay feature is not required then the delay values should be set to one.
Alarm Delay Example
Considerthefollowingsetupconfiguration:
Low temperature alarm set at 12°C using an “In delay” of 15 and an “Out delay”
of 30.
With these settings the temperature must drop below 12°C and stay below for
15 minutes before an alarm condition will be registered. During this 15 minute
period if any temperature reading is above 12°C then the delay is reset. This means
that the temperature must then remain below 12°C for a further 15 minutes before
the alarm is registered.
Once the alarm has been registered (after 15 consecutive minutes below 12°C) a
lowtemperatureSMSnotificationwillbesent.

Issue 1
Page 11 of 24
EL-SMS-2G-TP / TP+ / PROBE-G USER MANUAL
In order for the alarm condition to be cleared the temperature must rise and stay
above 12°C for at least 30 minutes.
Operating Modes
The ELSMS2G devices have three operating modes, these are:
Standby mode
Setup mode
Run mode
Standby Mode
Standby mode is the mode that the unit will be in when it is idle, i.e. when the unit
is not being setup or running. This state consumes minimal power. A one second
pressofthe“Status”buttonwillconfirmiftheunitisinthisstate.Theunitwillshow
eitherfourgreenorfiveredLEDflashes.FourgreenLEDflashesmeantheunit
isreadytobeginitsfirstsetupattempt.FiveredLEDflashesmeanthatthelast
attempt to set up the unit failed but it is ready for another attempt.
The unit will enter standby mode under the following conditions:
● Whenitispoweredonandtheunitisnotconfigured.
● Whenitispoweredonandtheunitwasconfiguredbuttherealtimeclock
hasresetduetoaninterruptiontothepower(e.g.ifthebatteriesranflat
during operation).
●When an attempt to setup the unit has been made and does not complete
successfully.
User Guide
●When the unit is in run mode and the stop monitoring button sequence
is pressed.
Setup Mode
ThisisthemodethatallowsaconfigurationSMStobesenttotheunitviatheApp.
Theunitwillnotreceiveaconfigurationmessageuntilyouhavefollowedthesteps
belowandtheunitisreadytoreceiveit.Ifyoutrysendingaconfigurationmessage
beforethis,theunitwillnotreceiveit.Theconfigurationprocesscanbestartedfrom
either standby or run mode.
Configuring the Unit
●Use the App to select the parameters you require.
Note that the Apps do not save settings for each device. The Android App will
rememberthesettingsusedforthelastdeviceconfigured.
●In the App, press the “Start” button (Android) or “Send SMS Message” (iOS)
at the bottom of the “Setup” screen.
● Pushthe“Status”buttonontheELSMSunitforfivesecondsandthen
releasethebutton.TheredLEDshouldbeginflashingonceeveryfive
seconds. Wait until you hear a triple beep from the sounder. When this
happenstheLEDwillchangetoadoublegreenLEDflasheveryfive
seconds.
● TheELSMSunitisnowreadytoreceivetheconfigurationSMS.Goahead

Issue 1
Page 12 of 24
EL-SMS-2G-TP / TP+ / PROBE-G USER MANUAL
and press the “Send” button in the App.
●Once you hear a double beep from the sounder you know the unit has
successfullyreceivedtheconfigurationmessage.Iftheconfiguration
SMSwasnotreceivedwithintwominutesyouwillhearfiveshortbeeps
from the sounder to signal that the setup did not complete successfully.
● Iftheconfigurationcompletedsuccessfullyyouwillreceivea
“Setup complete” SMS on the mobile device that was used to send
theconfigurationmessagetotheunit.
●The unit will then enter Run mode where it will begin monitoring the external
temperatureforalarmbreaches.Thiscanbeconfirmedbypressingthe
status button for one second and checking that the LED’s operate as per
the LED Flash Sequences.
Please note that the unit will not respond to button pushes once the setup
sequence has started.
The length of time required for the unit to register on the mobile network can vary
andisdependentontheunithavingsufficientsignal.Iftheunitisunabletoregister
withintwominutesitwillexitthesetupattempt.Thiswillbeindicatedbyfiveshort
beepsfromthesounderandfiveredLEDflasheswhenthestatusbuttonispushed.
SometimestheunitmaynotbelisteningforSMSmessageswhentheconfiguration
SMS is sent. This could be due to delays inherent in the GSM network such as
network outages, over subscription, routine maintenance work, message centre
technical issues etc. If a setup attempt does fail you can simply repeat the setup
process. If repeated attempts to setup the unit are failing then you should check that
availablesignalstrengthissufficientandtherearenoknownnetworkissuesthat
User Guide
could be causing the problem.
IfasetupattemptfailedbecausetheunitdidnotreceiveavalidconfigurationSMS:
1. Iftheunitwasnotpreviouslyconfiguredtheunitwillenterstandbymode
again.WhenthestatusbuttonispusheditwilldisplayfiveredLEDflashes
showingthatthelastattempttoconfiguretheunitfailed.
2. Iftheunitwaspreviouslyconfigureditwillsenda“NoSMSRxd”notification
tothemobilephonenumbersthatwerepreviouslyconfiguredtoreceive
“Summary”groupnotifications.TheunitwillthengobackintoRunmode
usingitspreviouslyconfiguredsettings.
IftheunitisconfiguredandoperatinginRunmodeitshouldbenotedthatmaking
anewattempttoconfiguretheunitwillstopitmonitoringtemperature.Ifthesetup
does not complete successfully then it will revert to run mode again, however, the
following parameters will have changed:
● Summarymessageswillbedelayedbyuptofiveminutes.
●Temperature delay counts will be cleared.
●Low and high temperature alarm history will be cleared.
●Minimum, maximum and average temperatures will be reset.
● Anypendingbatteryloworsummarynotificationswillbecleared.

Issue 1

EL-SMS-2G-TP / TP+ / PROBE-G USER MANUAL
Run Mode
FollowingasuccessfulconfigurationoftheunititwillenterintoRunmode.Inthis
modetheunitcheckstoseewhetheranynotificationmessagesareduetobesent
(i.e.alarmbreach,batteryloworsummarynotifications)andthenprocessesthe
notificationsinorderoftheirpriority:
●Temperature alarms have the highest priority
●Low battery alerts have medium priority
●Summary messages have the lowest priority
In Run mode the temperature is measured once every minute using the external
probe and the value is checked to see whether either the upper or lower
temperature alarm limits have been breached. If an alarm limit is breached (see
alarmdelayoperation)theunitwillsendanalertnotificationmessagetothe
contacts registered to receive the “alarm” group messages.
The battery condition is checked each time a temperature measurement is made.
Ifalowbatteryconditionisdetectedabatterylownotificationmessagewillbesent.
The buttons are disabled whenever the unit is actively sending an SMS.
Stop Monitoring
When the unit is in Run mode it can be put back into a Standby mode by pressing
the “Stop monitoring” button combination. This should be done whenever you want
to stop the unit from monitoring the temperature and sending alert messages.
Tostoptheunit,pressthestatusbuttonforfivesecondswhilstholdingdownthe
“Stop” button for at least one second. The unit will show the green LED for three
seconds after which it will reset. The power up LED sequence will then be displayed

SMS Retry Process (Continued)
The unit uses the retry sequence shown in the above diagram when attempting to
send either a temperature alert or battery low message:
Duringtheretryprocess,anyotherpendingnotificationmessageswillbe
postponed.
Theunitwillassumethatanotificationmessagehasbeensuccessfullydeliveredas
long as the message was successfully transferred to the mobile network for at least
one of the programmed numbers.
Ifafterfollowingtheaboveretrysequence,anotificationmessagestillcan’tbesent
to the mobile network, then the alert will be cancelled and the unit will continue
normal operation looking for new alert conditions to occur. If the cancelled message
wasanalarmnotificationthealarmconditionmaystillbereportedinthefollowing:
1) The alarm history in the next alarm message.
2) Most recent alarm in the next summary message.
The unit will only make one attempt to send a summary message. If the attempt
is unsuccessful then the summary message will be cancelled. Regardless of the
outcome the minimum, maximum and average temperature data for the period will
be reset.

Battery
For reliable operation of the unit it is recommended that only high quality alkaline
batteries are used. This will ensure the best possible battery life.
When the unit is in Standby mode, the battery status will be checked once every
three minutes. If the battery is low, the red LED will light for 1.5s when the
“Status” button is pushed. The unit will not send a low battery alert when it is in
Standby mode.
When the unit is in Run mode, it will send a low battery alert when it detects a low
battery condition.
It should be noted that the battery capacity will be reduced when the unit is
operating at lower temperatures. Also be aware that setting multiple destination
phonenumberstoreceivenotificationmessageswilldrainthebatterymuchfaster
and as such it is recommended that only one of the programmed phone numbers
isconfiguredtoreceivethelowbatteryalert.
If the unit is not going to be used for an extended period of time the batteries
should be removed from the product.
The expected battery life at room temperature, sending a daily summary message
anduptoonealarmnotificationperweek,isoneyear.
Thisestimateassumesthatonlyonedestinationnumberhasbeenconfigured.
Using additional destination numbers will reduce the expected battery life.
User Guide
Aerial and Signal Strength
The unit uses a built-in aerial to connect to the mobile network. The reliability of
the unit for sending messages is dependent on the signal strength available at the
locationofoperation.Thephysicallocationoftheunitwillalsoaffecttheavailable
signal strength and should be considered when situating the unit.
Themostrecentsignalstrengthisdisplayedineachnotificationmessagethatis
sent by the unit. For reliable operation the signal strength should be above three
bars. Operating below this signal strength may prevent the unit from being able to
send messages. Note that the unit may not always connect to the same service
provider if the SIM card permits roaming access.
The following table shows how the unit will report and display 2G signal strengths.
Signal

Signal strength
(ASU, 0 - 31)
Usability
1 115 to 107 0 to 3 Weak Signal / Intermittent operation
2 106 to 99 4 to 7 Poor Signal / Intermittent operation
3 98 to 87 8 to 13 Good / Reliable operation
4 86 to 77 14 to 18 Good / Reliable operation
5 76 to 53 19 to 31 Excellent / Reliable operation
Failuretoregisterontoamobilenetworkwouldusuallyindicateeitherinsufficient
signal strength or that the mobile network has failed to validate the SIM card (e.g.
barred or blacklisted SIM numbers).

Real Time Clock
The unit contains a real time clock which is used to add a timestamp to the outgoing
messages.Theclockissetautomaticallywhentheunitreceivesaconfiguration
message from the App.
Itshouldbenotedthattherewillbeadelayfromtheconfigurationmessagebeing
sent from the App to being received by the unit. This delay is largely dependent
on the mobile network and service provider and will therefore be unpredictable.
This means that the clock in the unit may lag behind the actual time of the device
usedtosendtheconfigurationmessagebytheamountthattheconfiguration
message was delayed.
Also note that the real time clock will be reset if the batteries are removed.
TheclockissetbyreconfiguringtheELSMSunitusingtheApp.
Time Zone
Outgoingnotificationmessagessentbytheunitcontainthetimezoneaspartofthe
time stamp information. The time zone is set to be the same as the local time zone
settingonthemobiledevicethatisusedtoconfiguretheunit.
Message Groups
The message groups allow each programmed mobile phone number to receive
differentcombinationsoftheavailablenotificationmessages.Eachmobilephone
number can be subscribed to any of the following message groups:

“Temperature Alarm” Message
The temperature alarm message shows a history of the last three temperature alarm conditions.
The temperature reading shown with each alarm in the history is the temperature reading taken
at the time the alarm was registered by the unit.
The time, date and time zone information is shown only for the most recent alarm. High
temperature alarms are indicated by the ‘H’ character, low alarms are indicated by ‘L’. Probe
errors are shown with the message PrbErr followed by O or C for missing or broken probes.
“Summary” Message
Thesummarymessageissentattheintervalspecifiedwhentheunitwasconfigured.
The following information is shown in the summary message:
●The minimum, maximum and average temperature readings since the last
summary interval.
●The most recent alarm condition and the date and time at which it was triggered.
●The most recent signal strength and battery status.
Note that the minimum, maximum and average temperature readings are reset at each
summary message interval even if the summary message itself was unable to be sent due to
lack of signal, network outage etc.
Summary messages may be delayed if the unit is sending higher priority messages such as the
temperature alarm or low battery messages.
“Low Battery” Message
The low battery message will be sent when the unit detects a low battery condition.

Probe Errors
If the thermistor probe goes either open or short circuit during normal operation this
will be reported in the alarm and summary messages as follows:
PrbErr O is displayed for a disconnected probe error (open circuit).
PrbErr C is displayed for a short circuit probe error (probably caused by a
faulty probe).
Setup Complete / No SMS Rxd message report the probe errors as follows:
PrbErr Open is displayed for a disconnected probe error (open circuit).
PrbErr Closed is displayed for a short circuit probe error.
When a probe error occurs, the unit internally registers the following temperature for
each condition:
Open Circuit Probe Error 51 deg C
Short Circuit Probe Error 50 deg C
For this reason, to receive probe error alarms, it is necessary to have the low alarm
enabled.
When a probe error condition is detected, the min/max temperature reading in
the next summary message with be shown as “.“, indicating that a probe error
was encountered during the last summary interval. Also, the average temperature
reading will be shown as “PrbErr” since the average temperature reading for the
summary interval will be invalid.
