9 Maintenance
9.1 Regular checks and maintenance
It is the obligation of the owner/operator to keep the hold-open system and each
conveying system barrier operational at any time. In its section on maintenance
and servicing, the DIBt approval refers to DIN 14677. After 1 year without func-
tional deficiencies, the functional test can also be performed every three months
instead of once a month.
In addition to the maintenance at the conveying system barrier, the batteries
in the SVG 522 must be exchanged every 4 years according to the approval
and modification document Z-6.5-1891 DIBt.
(Emergency power battery BA-7.2 Ah, part no.: 2 310 030)
It is not allowed to dispose of batteries along with domestic waste. After use,
batteries may be returned free of charge to the vendor or the disposal points
provided (e.g., municipal collection points or trade).
Monthly or quarterly functional test
The functional test of a hold-open system must at least include the following
elements:
a) Manual release test (manual release button or, if allowed, by manually
pushing the off button).
b) Release of the hold-open system by testing the fire detectors using the test
procedures defined by the manufacturer of the fire detectors (e.g., smoke
detectors by means of smoke detector testing device or heat detectors by
means of heat detector testing device). When hold-open systems are of
construction type 2, it must be ensured that the only intended use of the fire
detectors to be tested is controlling the particular hold-open system.
c) Restoration of the fire detectors from the alarm state.
d) Check whether there are environmental influences which affect the proper
functioning of the installed hold-open system.
e) Check whether the use in the immediate vicinity of the hold-open system
affects the latter negatively (e.g., presence of dust or water vapour).
f) Check whether the function of the hold-open system is negatively affected
by structural modifications and/or interactions with other trades in the
immediate vicinity of the hold-open system (e.g., subsequent installation of
intermediate ceilings) and whether the position of the fire detectors complies
with the DIBt's directive on hold-open systems (FeststellanlagenRL) and the
approval.
g) Check whether the fire and/or smoke barrier is released for automatic closing
after triggering.
