Functional check / overhaul
Through the detector self-test the DOT1151-Ex is subjected automatically to an extensive
electrical function check. However, it is still necessary to conduct a physical function test on
site in regular intervals.
Recommendation: A visual check of the detectors must be performed periodically (usual-
ly once per year). Detectors that are strongly soiled or which are mechanically damaged
must be replaced.
All detectors should be jointly replaced and factory overhauled in intervals of 6 to 8 years,
depending on the environmental conditions and the severity of contamination (see also
Maintenance instructions, document e1386, manual CS11.2, section 6).
Important:
The DZ1193 optoelectronic detector tester and exchanger as well as the
RE6T detector tester must not be used in explosion-hazard areas!
If mechanically damaged detectors must be scrapped, the plastic materials can be sorted
out based on the embossed code.
Electrostatic danger
The housing is made of plastic and has a surface resistance of >1Giga
Ω
which means
there is a risk of electrostatic discharge. Therefore the manual call point should not be
located where there is powerful ventilation. Cleaning with solvents is forbidden.
