Provisions for maintenance
and servicing
The rules and regulations for hazard areas and the provisions of the BG Chemie
must be complied with.
The LRS 04 Ex system should be kept operational at all times and be serviced at
least once per year according to manufacturer information in compliance with
the basic principles for maintenance and according to the rules and regulations
applicable for the specific hazard area in accordance with DIN 31051 in connec-
tion with DIN EN 13306.
In consideration of the special conditions of the operation environment, the
AP Duct Smoke Detector must be subjected to servicing and maintenance
according to VDE 0833 Part 1.
We recommend to subject the Duct Smoke Detector to a work revision
procedure after an operation period of 8 years. Work revision may be required
at an earlier stage due to special conditions present in the operation
environment: e.g. excessive strain, severe external influences, contamination,
etc.
Safety notes:
The smoke switch ORS 221 Ex must not be opened!
Caution:
The inlet tube is to be checked during regular visual inspection. For visual
inspection, remove the inlet tube from the LRS 04 Ex and remove any
present residue. After visual inspection and possibly cleaning, re-insert the
inlet tube correctly.
Caution:
Interaction of all devices and their correct functioning must be verified.
Caution:
Before any maintenance work, a work approval must be obtained and the
hazard area must be de-energised.
For function testing of the smoke switch ORS 221 Ex the test aerosol 918/5
by AP should be used.
