2 Disposal instructions
The device may not be disposed in the regular domestic waste.
Send the device directly to us (sufficiently stamped), if it should be disposed. We will dispose the device
appropriate and environmental friendly.
3 Operating advices and service notes
1. Disconnect the power plug before opening the housing or before working at closed devices!
The ALSCHU 480 does not disconnect a connected device at the adapter plug power outlet from the
mains! Therefore it is absolute essential for working at a device which is connected to the power
outlet, to stake it off and thus to disconnect it from the supply voltage.
2. The mains switch of the alarm device turns only the device itself off, the adapter plug power outlet will
be not disconnected!
3. For a durable and correct function you have to check the function in certain time lags, like every safety
device. For this the device has to be set to alarm by raising the sensors not less than once a month.
4. The device has to be treated carefully and has to be used corresponding to the preceding specifications (do not throw, do not let it dash against something, etc.).
5. The device may only be used in dry rooms.

4 Installation and initiation (may only be effected through adequate skilled personnel!)
1. Turn the power switch of the alarm device (ALSCHU 480) to the off-position and turn the selector to
setting "II" (to switch the power outlet from the shockproof adapter plug to currentless).
2. Hang up the alarm device via clamp to the favoured place (possibly choose an inconspicuous, but
easily reachable arrangement; but pay attention to enough sonic radiation of the built in alarm transmitter!). The device may only be used in dry rooms.
3. Put the sensor(s) (water sensor, floating switch etc.) to the place which shall be protected and fix it as
necessary.
4. Attach the sensor to the Ø2.5mm jack plug of the alarm device. At the use of more than one sensor
the sensors are meant to be connected together via two way connectors (GAZ-1) or extension cables
(VEKA 2, 5, 10) and then they must be attached to the alarm device.
5. The device which has to be switched in the case of alarm (e.g. lamp, siren, pump – attend the maximum acceptable breaking capacity! At inductive loads use a RC-element) has to be plugged in the
power outlet of the shockproof adapter plug.
Pay attention that the on-off switch (if existing) of the connected device is at the position „ON“ after
the initiation, otherwise the control by the ALSCHU 480 is not possible.
6. Plug the grounding contact adapter plug of the alarm device in the power outlet.
7. Switch the mains switch of the alarm device to "ON“. The operation indicator LED has to light now.
Attention: if there is no sensor connected the alarm will be activated automatically (safety switching
against accidental dismantling of the sensor). Pay attention at using socket outlet adapters that
a sensor is connected to all ends.
8. Put the selector switch of the device on position "I". The device which is attached to the power outlet
of the shockproof adapter plug has to switch on. If this is not true you have to check the wiring and
whether the power switch is set to on.
9. The favoured switch function can be chosen by the selector switch now:
I - in the case of alarm the power outlet in the shockproof adapter plug is currentless (the con-
nected device is turned off; break contact).
II - in the case of alarm the power outlet in the shockproof adapter plug is conducting (the con-
nected device is turned on; open contact).
10. Finally you have to carry out an operational check of the sensors. The alarm device has to be set to
alarm, whereas the alarm has to resound. Depending on the chosen function ("I" or "II") the connected device has to react. At misoperation please check the wiring in a currentless status again.
Turn off the alarm device, wait minimum for 5sec. and then turn it on again.
In the case of several connected sensors the test has to be repeated with every single sensor.
Your ALSCHU 480 is ready for operation now
5 Measures in case of alarm
- turn off the ALSCHU 480 and disconnect the power plug.
Attention: Please note that the alarm condition of the switch contact will be reset through the turn off of
the alarm device! This means that a device which is connected to this outlet will be turned off and respectively on. If you do not want this put the selector switch I / II during the attendance on the complementary position.
- determine the failure cause and clear the faults.
- turn on the alarm device again. Please note that between the unplug and plug of the device a time in-
terval of minimum 5sec. has to be passed. If necessary you have to put the selector switch I / II on the
right operating position again.

6 Safety regulations
This device was designed and tested considering the safety regulations for electronic measuring devices.
Faultless operation and reliability in operation of the measuring device can only be assured if the general
safety precautions as well as the device-specific security advices in this users manual are considered at
the usage of this device.
1. Faultless operation and reliability in operation of the measuring device can only be assured if the device is used within the climatic conditions specified in the chapter „Specifications“.
2. Always disconnect the device from its power supply before opening it. Take care at the installation of
the device and circuit points that the unit’s contacts are protected against direct contact.
3. Standard regulations for operating and safety for electrical, light and heavy current equipment have to
be observed, with particular attention paid to the national safety regulations (e.g. VDE 0100).
4. When connecting the device to other devices (e.g. PC) the protective circuit has to be designed most
thoroughly. Possibly internal connections in third-party devices (e.g. connection of ground with protective earth) may lead to undesired voltage potentials.
5. If it is supposed that the device can not be prosecuted riskless the device has to be switched off and
has to be assured against further usage through labelling.
The operator’s safety can be affected by the device if it for example:
- shows visible damage
- does not work anymore like prescribed
- was stored under inappropriate conditions for a longer time
In case of doubt the device should strictly be send to the manufacturer for repairing /servicing it.
6. Warning: When running electric devices parts of them are unavoidable electrically live. Unless the
