4.11. Limits of use
The limits that can be taken from the technical data in section 3 are to be kept.
The limits for the calculation of the safety integrity of the sounder in systems is to be taken from section 4.4.
Changes to the sounder are only possible via the manufacturer. The safety parameters must be recalculated
and the functional safety must be tested. Changes by the user are not allowed and lead to voiding of the
warranty.
4.12. Requirements for the installation and putting into service
a) The sounder corresponds to state-of-the-art technology and was constructed taking into account the
specific regulations and guidelines.
b) The operating manual and the safety manual are aimed at educated and authorised electrical tech-
nical personnel. Their contents must be made available to the technical personnel and implemented.
c) The electrical connection can only be carried out by persons authorised for this. Before connecting it
is to be ensured that the sounder is not live.
d) The safety instructions of this operating manual, the local installation standards as well as the valid
safety regulations and accident prevention guidelines are to be observed.
e) The sounder must be selected so that a clear perceptibility of the acoustic signal at maximum ambi-
ent noise level can be guaranteed. The warning signal must exceed the ambient noise level by
+10dB(A).
f) When using numerous signals (tones), they must be clearly distinct in order to enable specific ac-
tions by trained personnel.
g) Do not install two warning devices directly next to one another as mutual influencing during simulta-
neous operation cannot be ruled out. A distance of >1m fulfils the requirement.
h) The front part can be removed by releasing the 4 screws on the front side. Ensure a clean and un-
damaged seal during the installation.
i) The connection assignment is illustrated in section 4.13.
j) The cable screw joints with which the device is equipped are intended for round cable cross-sections
and an outer diameter of 8mm to 12mm. This guarantees the seal effect of the cable screw joint. If
cables with other diameters or shapes are to be used, then other suitable cable screw joints must be
used. The IP protection category IP67 cannot be impaired.
k) During installation make sure that the cable(s) is/are secured against pulling and twisting. Please
note: the devices are not intended for mobile use.
l) The opening of the horn is not to be facing upwards, particular when in use outside or in a dusty area.
m) The tones are set with help of the DIP switch S1, see tone table section 3.5.
n) The housing screw plugs (Torx-T20) of the sounder part are to be tightened with a torque of approx.
2 - 2.5 Nm for at least two cycles when closing the housing.
o) The correct function of the sounder is to be checked when newly commissioned, recommissioned
and after every repair. The safety function in particular is to be validated. The function test as de-
scribed in section 4.7 is also to be carried out.
p) Before repair, the supply voltage on the type plate is to be checked. The wrong operational voltage
can lead to damages or to the destruction of the equipment.
q) The sounder can only be operated in an undamaged and operationally safe condition within the spe-
cific data.
r) The operator is responsible for the trouble-free operation of the device.
