1. GENERAL DESCRIPTION
The Mobeye WaterGuard is a battery operated GSM module used to send out an alarm after
detection of a water based fluid, after a triggered input or - if external power supply is used- after
a power failure. It is also possible to monitor the water level, in such a way that the Mobeye
WaterGuard detects the absence of water.
The Mobeye WaterGuard is pre-programmed with standard action-reaction patterns. To change
this behaviour please refer to chapter 4.
The factory settings of the Mobeye WaterGuard cause following reactions:
- When the Mobeye WaterGuard detects water, it sends an alarm SMS text message and calls to
the phone numbers as programmed. The SMS message contains the text ‘Mobeye Water
alarm.
- As soon as no water is detected anymore, an SMS text message is sent to the set telephone
numbers containing the text ‘Mobeye Water Level OK’.
- In case one of the inputs is activated by a sensor, the Mobeye WaterGuard sends an alarm
SMS text message and calls to the phone numbers as programmed by the user.
- In case the water sensor and/or the inputs remain in the alarm status, the Mobeye WaterGuard
repeats sending the SMS alarm message every four hours.
- In case the batteries need to be replaced, the Mobeye WaterGuard sends a ‘battery low’ SMS
text message to the administrator.
- In case an external power supply is used and a power failure occurs, the Mobeye WaterGuard
sends a ‘power failure’ SMS text message to the administrator. In case the power is restored,
the Mobeye WaterGuard sends a ‘power restored’SMS text message to the administrator.

2. GETTING STARTED
To get started with the Mobeye WaterGuard at least the following steps need to be taken in
following order:
1. Place SIM card (with PIN code 0000 or without PIN code)
2. Connect the water sensor to the unit
3. Place the batteries
4. Enter the program mode
5. Program at least one telephone number (administrators’ number)
6. Arming/disarming the system
These steps are further explained in this chapter. After these steps the module will be
operational.
2.1 PLACE A SIM CARD
Open the enclosure with the 4 screws and insert a SIM card into the module. Push the black
cover outward slightly to open the holder. Before installing the SIM card should have PIN code
"0000", or be free of a PIN code.
(A PIN code can be changed or removed by putting the SIM card in a mobile phone and change or remove
the PIN in the security menu.)
NB: make sure the SIM card is inserted before the batteries are placed. In case of a SIM card
change, please first remove the batteries (and remove any other external power supply).
2.2 CONNECT THE WATER SENSOR TO THE UNIT
Plug the external water sensor into the metal socket and press it firmly.
2.3 PLACE THE BATTERIES
Place the two batteries (CR123) in the module. Use the +/- indication for the correct placement.
The green LED will flash to indicate that the module is not configured (at least one telephone
number should be programmed).
2.4 ENTER THE PROGRAM MODE
Directly after placing the batteries, the Mobeye WaterGuard switches to the program mode. First
the GSM module establishes network connection. During this time the LED flashes 2 sec. on/1
sec. off. Within 10-30 seconds the connection is established and the status LED starts flashing 1
sec. on/1 sec. off (or ‘on’ in case the first telephone number has been configured).
The Mobeye WaterGuard returns to the program mode by pressing the on/off button during 5
seconds, until the LED starts flashing (or turns to ‘on’).
As long as the unit is in the program mode, the status LED is on (or flashing 1 sec. on/1 sec. off if
the module has no configuration). During the first 3 minutes, the GSM module remains open,
ready to receive SMS commands. After 3 minutes a time-out occurs and the GSM module
switches off in order to save the batteries. The unit returns to the low power operational mode.

2.5 PROGRAM AT LEAST ONE TELEPHONE NUMBER
The Mobeye WaterGuard is able to send messages up to 5 telephone numbers. The first
telephone number belongs to the administrator. Technical messages (like “battery low”) are sent
to the administrator only. Without the administrators’phone number, the Mobeye WaterGuard
cannot not function.
When the WaterGuard is in initial (factory) status and the batteries are placed (so the LED is
flashing), the administrators’number is programmed by calling the telephone number of the
Mobeye WaterGuard using the administrators’ phone. The unit will recognize this number and
store it as administrator (telephone number 1). The administrator will receive a confirmation SMS
text message including the security code. This code is needed to program the other settings in
the unit.
NB: for this way of programming the number recognition in the administrator’s phone must be
‘on’. To program or change the administrators’ number by SMS command, please refer to 4.4.1.
2.6 SWITCHING ON/OFF
After the previous steps, the Mobeye WaterGuard is ready for use.
It is armed (switched on) automatically. The green LED blinks once in 3 seconds.
In order to switch off (disarm) the Mobeye WaterGuard:
- Press the on/ off button at the upper side for 1 second. The green LED switches off to indicate
the armed status.
In order to switch on (arm) the Mobeye WaterGuard:
- Press the on/ off button at the upper side for 1 second. The green LED blinks once in 3 seconds
(or permanently in case of an external power supply) to indicate the armed status.

3. USE OF INPUTS AND EXTERNAL POWER SUPPLY
3.1 USING THE INPUT(S)
It is possible to connect external sensors to the inputs. As a standard reaction after a triggered
input, the Mobeye WaterGuard sends an SMS text message to the preset numbers and calls
these numbers.
Insert the 2 wires of an external sensor through the hole of the enclosure to the inside part and
next in the two connectors of input 1 (press on the green pins for connecting the wires). It does
not matter which wire is connected to which connector. If necessary the wires can be extended
up to 5 meters using appropriate wire material.
When using a second input, connect this to input 2.
As default the inputs are programmed as Normally Open (NO)
contacts. This means the inputs are triggered in case the input is
closed during at least 1 second. In case the contact should be
Normally Closed (NC), please refer to paragraph 4.4.5. In case a
sensor should be activated shorter or longer before evoking an
alarm, please refer to 4.4.6.
3.2 USING EXTERNAL POWER
Although the Mobeye WaterGuard is designed to run on batteries,
it is possible to use an external power supply. In this mode the
module is always in connection with the GSM network and
therefore always in program mode. In case the power fails, the
batteries take over the functioning and the administrator is
informed by an SMS text message. The module continues
operating albeit in the low power mode. This means the GSM
module switches off and only establishes network connection in
case it needs to send out an alarm, test message or battery low
alert.
Connect the external power adapter (or any other regulated
12VDC power supply) to the power input of the connector (press
on the green pins for connecting the wires):
- V+ (black lead with white stripe) to “+”
- Ground (black lead) to “-“

4. EXTENDED OPTIONS
To program the Mobeye WaterGuard, the GSM module must have network connection. In case
only batteries are used, first switch the unit to the program mode. Next send SMS commands for
the configuration.
All settings are stored and will be kept in the unit, even in case the power supplies are removed.
4.1 PROGRAM MODE
Directly after placing the batteries, the Mobeye WaterGuard switches to the program mode. First
the GSM module establishes network connection. During this time the LED flashes 2 sec. on/1
sec. off. Within 10-30 seconds the connection is established and the status LED starts flashing 1
sec. on/1 sec. off (or ‘on’ in case the first telephone number has been configured).
The Mobeye WaterGuard returns to the program mode by pressing the on/off button during 5
seconds, until the LED starts flashing (or turns to ‘on’).
As long as the unit is in the program mode, the status LED is on (or flashing 1 sec. on/1 sec. off in
case the module has no configuration). During the first 3 minutes the GSM module remains open,
ready to receive SMS commands. After 3 minutes a time-out occurs and the GSM module
switches off in order to save the batteries. The unit returns to the low power operational mode. In
case the unit is connected to an external power supply, the WaterGuard has network connection
all the time and the unit is in program mode all the time.
The program mode is interrupted by pressing the on/off button during one second until the LED
switches off. The unit is switched off completely (disarmed).
4.2 THE SECURITY CODE
For configuration activities the security code of the Mobeye WaterGuard must be used. The initial
security code is ‘1111’. In this manual this code is referred to as <CODE>.
4.3 PROGRAMMING THE SETTINGS BY SMS
The settings are programmed by SMS text messages.
- Be sure the WaterGuard is in program mode (please refer to 4.1).
- Send an SMS message with following content:
<CODE> <command>
- Do not forget the space character between <PIN code> and <command>.
- The commands are case sensitive.
- Several commands may be combined in one SMS message (with a maximum of 160
characters) by placing a # between the commands.
<CODE> <command1>#<command2> ...... #<commandN>
The green LED blinks 3 times to indicate the successful configuration. In case of an incorrect
command, the LED flashes 5 times.
In 4.5 the complete scheme with SMS commands is listed

4.4 POSSIBLE GENERAL SETTINGS
This paragraph describes the general settings for the WaterGuard.
4.4.1 Phone numbers
The Mobeye WaterGuard is able to send alarm messages up to 5 phone numbers. The first
telephone number (TEL1) belongs to the administrator. Only this number receives all system
messages. The other phone numbers (including the administrator) only get the alarm messages.
To set or change telephone numbers:
SMS command 1st telephone number: <CODE> TEL1:<tel. number>
SMS command 2nd telephone number: <CODE> TEL2:<tel. number>
.... similar for TEL3...TEL5
To delete telephone numbers:
SMS command delete 1st telephone number: <CODE> DEL1
.... similar for DEL2...DEL5
In case a foreign number needs to be entered start with 00 follow by the country code (e.g.
0031612345678).
4.4.2 Identification text
It is possible to add a standard identification text (NAME) to all messages sent out by the Mobeye
WaterGuard. The alarm messages are a combination of the name and the alarm text. A user
defined identification has a length of maximum 20 characters. The default identification text is
‘Mobeye’.
SMS command identification text: <CODE> NAME:<free text>
4.4.3 Alarm text
Unique alarm texts can be programmed into the Mobeye WaterGuard. User defined texts have a
maximum length of 20 characters.
Following default texts are programmed:
Water alarm <TEXT1> : Water alarm
Water level restored <TEXT2> : Water level OK
Triggered input 1 <TEXT3> : Alarm 1
Triggered input 2 <TEXT4> : Alarm 2
SMS commands text 1: <CODE> TEXT1:<free text>
SMS commands text 2: <CODE> TEXT2:<free text>
.... similar for TEXT3 and TEXT4
4.4.4 Alarm notification type: SMS or SMS + call
As default behaviour, after an activated input the Mobeye WaterGuard notifies by SMS text
message followed by a telephone call (beep signal). The combination of SMS text and the call
increases the chance of getting the attention of the contact persons. It is possible to disable the
call (OFF), so that only an SMS message will be sent. The default alarm notification type is ON
(SMS + call).
SMS command alarm notification type: <CODE> CALL:xxx
4.4.5 Input type
As default behaviour the Mobeye WaterGuard sends out an alarm after detection of a water
based fluid. In case the water level in a tank should be monitored, the WaterGuard needs to send
out the alarm as soon as the sensor detects the absence of water. As default the input type IN3 is
set to NO (normally open); for alarming the absence of water, IN3 needs to be changed to NC
(normally closed).

9
SMS command input type input 3: <CODE> TYPEIN3:xx
The input types IN1 and IN2 define the character of the additional inputs IN1 and IN2. This can be
Normally Open (NO) or Normally Closed (NC). In case an input is set to NO, the alarm will be
triggered as soon as the terminals of the input are closed. If the input is set to NC, the alarm is
triggered in case the connection between the input terminals is broken. The default input type is
set to NO.
SMS command input type input 1: <CODE> TYPEIN1:xx
SMS command input type input 2: <CODE> TYPEIN2:xx
4.4.6 Input delay time
The input delay time defines the time that the input are triggered before an alarm is initiated. If the
input returns to the non-alarm status within the delay time, no alarm is sent. The time can be set
between 0 and 999 seconds.
As default, the input delay time is set to 1 second.
SMS command alarm delay input 1: <CODE> DELAY1:xxx
SMS command alarm delay input 2: <CODE> DELAY2:xxx
SMS command alarm delay water sensor: <CODE> DELAY3:xxx
4.4.7 Inactive time
The “inactive time” defines the time input 1 or input 2 is not active after an activation. In case the
time is set to “0” (minutes), the input is active again immediately after returning to the non-alarm
status. In case the time is set to e.g. 30 minutes, the input remains inactive for the first 30
minutes. In case the input is again (or still) activated after these 30 minutes, a new alarm
message is sent. The time can be set between 0 and 60 minutes. As default, the inactive time is
set to “0”.
SMS command inactive time input 1: <CODE> INACTIVEIN1:xx
SMS command inactive time input 2: <CODE> INACTIVEIN2:xx
SMS command inactive time Water sensor: <CODE> INACTIVEIN3:xx
4.4.8 Alarm repeat time
In order to emphasize the urgency of the alarm messages, all alarms can be repeated. As long as
the alarm status has not returned to the inactive status, the SMS alarm will be repeated after the
‘alarm repeat time’. The time can be set between 0 and 24 hours. As default the alarm repeat
time is set to 4 hour.
SMS command alarm repeat time: <CODE> REPEAT:xx
4.4.9 Test SMS text message
The Mobeye WaterGuard can send regular test SMS messages (´keep alive’) to the
administrator, to ensure the proper functioning of the unit. The test message function is only
active in case the unit is armed.
The interval between the test messages can be set between 0 days (no test message) and 30
days. The default test interval is set to 0 (no test message).
SMS command interval test message: <CODE> TEST:xx
4.4.10 Power failure SMS message
In case the Mobeye WaterGuard is powered externally and the power fails it sends an SMS text
message to the administrator. The message is only sent in case the unit is armed. This message
can be set to ‘OFF’. The default setting for the ‘power failure SMS text message’ is set to “ON”.
SMS command power failure message: <CODE> POWERSMS:xx
