Maintenance
9.1 Routine inspection / monthly inspection
ú
The hold-open system must be kept permanently in a good operating condition by the operator; in particular
the door leaves must not be blocked (e.g. by wedges, chains or other objects which prevent the door leave
closing automatically).
ú
In order to ensure that the hold-open system is in a good condition, a routine test must be carried out at regular
intervals on site.
If twelve monthly functional tests in succession do not reveal functional faults,
the hold-open system only needs to be checked at intervals of 3 months. If a functional fault is established dur-
ing the quarterly functional tests, serviceability is to be re-established without delay and proved through at least
three successive monthly functional tests.
ú
This routine test may be carried out by anyone, following appropriate briefing through GEZE.
The functional test of a hold-open system must contain at least the following elements:
ú
Check on the manual trigger (manual trigger switch or by manual disengagement if permitted);
ú
Check on triggering of the hold-open system by testing the fire detectors (see chap. 6);
ú
Check on automatic resetting of the fire detectors from the alarm state;
ú
Check whether environmental influences impair the function of the hold-open system installed;
ú
Check whether the environment in the direct vicinity of the hold-open system has a negative influence on it
(e.g. occurrence of dust or steam);
ú
Check on whether constructional changes and/or interaction with other product groups in the direct vicinity
of the hold-open system has a negative influence (e.g. later installation of suspended ceilings) and whether the
positioning of the fire detectors complies with the general construction technique permit (see chap. 3.5);
ú
Check whether the fire protection or smoke protection closer is released for automatic closure after triggering.
When wireless assemblies are used in the hold-open system:
ú
The quality of the wireless connections must be tested (see chapter 4.5.2 Connection quality). Construction
changes or new electronic assemblies in the direct vicinity of the hold-open system can interfere with the wire-
less connections.
ú
The charge state of the batteries in the wireless assemblies GC 172, GC 173 and GC 175 must be tested.
An empty battery is indicated as a warning at the status LED of the wireless module GC 171 (see chap. 4.5.1)
Scope, result and time of the functional test must be documented in the GEZE log book for hold-open systems
and made available to the operator. These records must be stored by the operator.
The operator must be informed if obvious functional problems and/or damage to the fire protection or smoke
protection closer occur.
9.2 Annual testing and maintenance
ú
In addition, the operator is responsible for the organisation of the testing and maintenance of all the compo-
nents of the hold-open system, so that it is guaranteed that these components work properly and without
interference. This testing and maintenance must be carried out at least once a year in accordance with the
recommendations of the manufacturer. Scope, results and date of this annual testing must be recorded in the
GEZE log book for hold-open systems which must be kept by the operator.
ú
Regular maintenance and testing may only be carried out by a specialist or a person trained for this purpose.
Maintenance of the hold-open system must include the elements of a functional test in accordance with chapter
8 and the following additional elements:
ú
Check the correlation with documentation and general construction technique permit;
ú
Cleaning of the function-related components of a hold-open system, in as far as their contamination can lead
to impairment; (the measuring chamber of a smoke detector must not be opened).
ú
Check whether the hold-open system is triggered in the event of a power failure;
ú
Check whether the hold-open system is triggered in the event of a fire detector being removed.
When wireless assemblies are used in the hold-open system:
ú
Change the main battery and the slave battery of GC 175 in a 5-year cycle, even without “battery empty”
display on the GC 171.
Scope, result and time of the maintenance carried out must be documented and made available to the operator.
