Functional test
The functional test of a hold-open system comprises the following checks:
a) Manual release (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). Where hold-open
systems of construction type 2 are concerned, 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 effects 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. occurrence of dust or water vapour).
f) Check whether the proper functioning of the hold-open system is negatively affected by
structural modifications and/or interaction 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 directive of the DIBt (FeststellanlagenRL) and
the type approval.
g) Check whether the fire barrier and/or the smoke protection closure are released for automatic
closing after triggering.
