Hold-open systems regulations / information
– General building regulations pertaining to the approval of the
hold-open system concerned
– EN 1155
– EN 14637
1. General
1.1 In the case of fire doors (and similar
shutters/closures/ barriers) that are
held open by hold-open systems, the
sweep area necessary for the closing
operation must be kept constantly
clear. This area must be clearly
identified by lettering, floor markings
or similar. Where necessary, structural
measures must also be implemented
to ensure that cables, leads, lines,
pipes, stored/deposited goods or
components (e.g. false ceilings or other
overhead items/elements) are reliably
prevented from falling into the sweep
area.
1.2 Any hold-open device must be
capable of being released by hand,
without adversely affecting the
functional capabilities of the
automatic release device. In the case
of door closers with electro-magnetic
hold-open, the manual release may be
performed by a small tug applied to
the door leaf. If surface electro-
magnets or freeswing door closers are
used, a pushbutton may be provided to
facilitate manual release. The manual
release pushbuttons employed for this
purpose must carry the wording
“Close Door” or equivalent. The
pushbutton must be located in the
immediate vicinity of the door and
must not be concealed by the door
when it is held open.
2. Routine Inspection
2.1 The hold-open system must be kept
by the operator in a constantly good
operating condition, and inspected at
least once a month to ensure that it is
functioning properly.
2.2 In addition, the operator is obliged
at least once a year, or at shorter
intervals if specified in the approval
certificate, to inspect all the devices to
ensure that they are operating and
interacting properly and without fault,
and to carry out or instigate adequate
maintenance. The associated test,
inspection and the maintenance work
may only be performed by an expert
or an appropriately trained person.
2.3 The scope, result and time of the
periodic inspection are to be recorded.
These records must be retained by the
operator.
