4.4 Function
The SYR SafeTech Connect Leakage Detector is an efficient leakage protection system according to DIN
3553. Thanks to permanent monitoring, any leak is detected at an early stage and the risk of extensive
water damage is reduced because the water supply is cut off automatically.
The SafeTech Connect Leakage Detector features an electronic water metering device (by means of a
turbine), an electrically-driven shut-off valve, a pressure sensor to monitor the smallest leakage volu-
mes and a multifunctional display. In addition, the device determines water hardness and indicates it
in three stages.
The SYR SafeTech Connect Leakage Detector can connect to the SYR App via its AccessPoint. In case
of an active Internet connection, the SafeTech Connect transmits the measured values from the drin-
king water installation, e.g. volume flow, flow rate per time, duration of volume flow, pressure drop and
temperature via a secure connection.
Even if the Internet connection is down, the parameters will continue to be monitored. However, during
that period, there is no communication with the server and no notification in case of derogations from
set parameters. Of course, the system can also operate without Internet connection.
The mains adapter is used for power supply. The scope of delivery includes a battery for the short-term
protection in case of power failure.

7. Operation and settings
7.1. Operation and settings via the SYR App
It’s easy to set your SYR SafeTech Connect Leakage Detector via the SYR App on your smartphone or
tablet.
Simply install the current SYR App on your smartphone or tablet. You can also use your computer
(http://syrconnect.de) and follow the user instructions.
You will fi nd exact instructions for the initial setup of your device in the appended instructions.
The SafeTech Connect can also be used without an Internet connection. In this case,
functions like notification by text messages or e-mail are not available though. The
SafeTech Connect cannot be connected to other devices in this case either, like e.g. the
radio-controlled floor sensor SafeFloor Connect.

Operation and Maintenance SafeTech Connect Leakage
Explanation and setting options factory settings
User profile
Individual setting of the device, adjusted to the user profi le. A maximum of eight
user profi les are possible.
Example:
Usually, the two daughters are present at weekends. The two girls like to take
long, extensive showers. To make sure that the parents have sufficient water,
too, they create a new profile with the corresponding parameters.
SYR tip: Refer to the smart self-learning phase of the SafeTech Connect to
determine the optimum safety levels for your new profile.
Volume-based leakage
Present
(active)
Absent
Maximum amount of water drawn after opening a draw-off point. The setting for
volume-based leakage ranges from10 to 9,000 litres. Volume-based leakage may
be switched off.
Example:
The draw-off point with the highest draw-off amount is a bathtub with a capa-
city of approximately 120 litres. Set the value of leakage in the presence-mo-
de to 200 litres so that the bathtub can be filled up without any problem and
you can still draw water.
Time-based leakage
300 l
If a draw-off is registered that takes longer than the time set for a specifi c volume,
the device will isolate the system. Time-based leakage can be set to 30 minute
intervals, ranging between 0.5 and 25 hours. This setting can also be switched off.
Example:
In addition to the amount of water set for volume-based leakage, a period of
time can be determined when water may be drawn without interruption. If, for
example, the time-based leakage is set to 60 minutes, the SafeTech Connect
will isolate the system once this time has elapsed, even if the set volume has
not yet been reached.
60 minutes
7.1.1. Settings range
Please find below the most important terms for the settings range of the SafeTech Connect Leakage
Detector in the SYR App. Examples are given for illustration.

15
If the SafeTech Connect detects unusual fl ow rates within short periods of time,
the device will consider this as leakage. Flow-based leakage can be set up to a
volume of 5,000 l/h, yet this setting can also be switched off completely.
Example:
The factory setting of a maximum flow of 3,000 l/h continues for at least
one minute — mostly in case of pipe bursts: the SafeTech Connect Leakage
Detector will immediately shut off the pipe system.
SYR tip: Install an additional radio-controlled floor sensor SafeFloor in cri-
tical places. This will determine local water leaks, regardless of the selected
settings. The SafeFloor can be connected to the SafeTech Connect so that
the latter can immediately isolate the system.
3.000 l/h
Return to “present” mode
The user can determine the time when a selected profi le shall be active. Once
the set time is over, the SafeTech Connect will return to the “present” mode. The
options for the settings range between one hour and 28 days. Times will be given
in hours.
Example:
You will be away from home for four days and therefore you select a mode
with low water consumption. If you select your return time to “present” to be
four days, the SafeTech Connect will automatically switch back to this mode
after the selected time and you do not have to worry about anything.
Microleakage test
Time indica-
tion
The device will check at regular intervals for the smallest of leaks. The microlea-
kage test can be switched on or off.
Warning sound
Warning
The warning sound can be switched on or off.
Self-learning phase
On
During the self-learning phase, the SafeTech Connect Leakage Detector analy-
ses water consumption and the usual household usage. The measured values can
then be used for your own, selected profi le. The duration of the self-learning pha-
se can range between one and 28 days.
