- dust or flammable gases, fumes or solvents
- strong vibrations, shocks, impacts
- strong magnetic fields such as near machines or loudspeakers
• Never use the product immediately after it has been brought from a cold into a
warm room. Condensation that forms might destroy your device. There is danger
of a life-threatening electric shock!
• Leave the product switched off and wait until it has reached room temperature.
This can sometimes take several hours.
• In industrial facilities the accident prevention regulations of the association of the

C Lower half casing
Installation and connection
• Install the signal siren with the three fixation holes (A) on a surface that is suitable for it.
Make sure that no cables, electric leads, gas or water pipes are damages when
drilling or screwing!
Do not tighten the screws forcibly otherwise the casing of the signal siren is
damaged. The screws should not be screwed too loosely as they can come off
through vibrations.
• The screw cap (B) is to be unscrewed anti-clockwise from the lower casing-half (C).
• The two white cables are to be connected through a bipolar screw clamp (not included
in delivery) to the supply voltage (the allocation of the two white cables to "N" or "L" is
unimportant).
As a connection cable, a plastic cable is to be used 3x 0.75 mm
earth conductor/protection contact (yellow/green wire) is not needed. The wire-end is to be
secured with insulating tape or with another single-pole screw clamp.
Attention!
When connected work can be carried out at the supply voltage. If you are not
an expert who is able to make this connection and installation, you should let a
specialist (electrician) do this for you. With improper work at the supply voltage, you
not only endanger yourself but also others - danger through an electric shock!
Before the product is installed and connected you have to switch it off at the control
that causes the signal siren to go on; secure it against unintended operation (for
example with warnings).
Danger to life through an electric shock!
