Full Tank Alarm for sewage tanks • Installation instructions
Subject to design modifications..
VA-ALERT
Alarm unit must
not be disposed with
household garbage,
but should be handled as
electronic waste.
Safety /
important to consider
• Carefully read the installation manual
before assembly
• Alarm Device may only be installed in dry
indoor areas.
• The equipment may only be used for indica-
tion of high level alarms in sewage tanks or
water tanks.
• Can not be used in connection with oil or
petrol! Nor in hazardous areas!
• If the tank is to be below ground, be sure
that the sensor can be accessed simply by
installing a manhole, etc. This is to avoid
having to dig to access the sensor for any
future sensor replacement.
• The sensor is available with 2 or 10 m cable.
If sensor cable needs to be extended: Use
RKK 2 x 0.75 mm2. Do not use multiconductor
cable (for pump control signals or the like).
See more in ”Splicing” on page 3.
Function Description
VA-ALERT for sewage tanks is a unit with
conductive probe that use AC technology
for the sensor. The unit is designed to be
mounted directly onto a wall indoors and is
powered by 3 AA batteries with a life expec-
tancy of at least 3 years.
VA-ALERT has an internal relay which allows
connection to alarm lamp or SMS-alarm unit.
VA-ALERT is used for cisterns / tanks con-
taining electrically conductive liquids. Alarm
is given when the contents of the tank has
reached to the two electrodes of the sensors
lower part. The unit has built-in warning for
low battery voltage, which warns of battery
replacement in due time before the battery is
exhausted (about 3-6 months before).

Installation
Installation should be done by a qualified
and competent installer.
Installation of sensors:
Mount sensor by the cistern connection
and screw the sensor connector in the
cistern sleeve.
Installation of signal wire / splice:
Use a sensor cable such as RKK 2 x 0.75
mm2to an appropriate location for the
alarm device. The interconnection of the
signal line and the sensor is made using the
supplied coupling piece. Do not connect
the signal line in a multiconductor cable
together with other signals (230 V pump
control, etc.).
Fix the joint location with electrical tape,
insulating tape or equivalent. Protect the
power cord in the ground with conduit or
the like.
NOTE! The sensor with 10 m
cable is not supplied with con-
nector.
If the tank is below ground, ensure that the
sensor can be accessed in a simple way,
eg by installation of a manhole. This is to
avoid having to dig for accessing the sen-
sor for any future sensor replacement.

Activating the alarm unit:
• Install the alarm unit in a location where
it can be easily observed and checked.
The sensor cable is connected to 3
and 4 on the terminal block. If an exter-
nal power supply is used (optional),
use connector 1 and 2 on the terminal
block. Connection of external equipment
can be made via the voltage-free relay
output contacts at 5,6,7.
• After sensors and other connections are
complete, put 3 x AA batteries of alkaline
type in the battery holder (calculated
life-span about 3.5 years).
Back side of the front to the VA ALERT Wiring on terminal
When using external power no
batteries should be used. (Mains / batt-
ery eliminator 12 VAC or 12 VDC is
optional.
• Insert the batteries into the holder and
verify that the polarization is correct (see
symbols in the battery holder). The
unit will now give a quick flash about
every two seconds. If this occurs, the
unit is in operation.
• If flash is not delivered, verify polariza-
tion or replace the batteries.
Functional testing of sensors
and alarm device:
To test the alarm: Immerse the sensor
in water (do not use rainwater or battery
water, as this is to clean and has poor
conductivity). Alternatively, the sensor elec-
trodes could be short circuited with a cable
stub or a cable clamp. Once this is done,
the unit reacts after about 4 seconds, the
buzzer will sound and the red LED flashes
every two seconds. The relay contacts will
switch. By pressing the button, the sound
is muted. If this occurs, the alarm is pro-
perly functioning. If this does not happen,
check the Troubleshooting section.
