Security Locks
Emergency Escape Locks
Panic hardware fitted to final
exit doors has to combine the
requirements for safety in
allowing egress at any time
and yet security, to prevent
unauthorised entry into the
school or unauthorised
egress. Final exit doors are
often misused as they can
provide a ‘shortcut’ to the
playground or other areas of
a school; this can compromise
security, especially if they do
not lock correctly after use. It
is therefore critical that panic
devices are capable of
self-locking correctly after
operation, by using Pullman
type latches and a door
closer. dormakaba supply and
extensive range of touchbars,
crossbars, panic bolts and
latches.
dormakaba locks are all CERTIFIRE approved and CE marked
to BS EN12209. Their grade 8
classification on the third digit
donates a closing force of
below 15N on doors up to
200kg in weight to ensure ease
of operation. Independent
tests have shown the exact
closing force to be 7N, thus
ensuring that the door closer
will be capable of engaging the
latch easily. All lock cases have
common dimensions allowing
interchangeability of locks
should the function of the door
change at any time. dormakaba Locks are prepared to take
‘bolt through’ lever furniture
which is considered essential
for school projects.
Emergency escape locks
provide escape at anytime by
the simple operation of the
lever handle fitted to the lock.
Although they must not be
used on final exit doors within
a school (panic hardware to
BS EN1125 must be used
here), they can be used on
internal doors to provide
extra security, yet allow
escape in the event of an
emergency. A typical example
would be a classroom door.
An emergency escape lock
can enable a teacher to lock
the door to prevent any entry
into the classroom yet
operation of the lever handle
from within the classroom,
will unlock the door and allow
exit.
The majority of doors within a school will be fire doors. It is
therefore vital that the correct ironmongery is specified:
the door closer, the lock, the handle and the intumescent
seal. Firstly, let us look at specifying the correct door
closer.
The Door Closer
There are two main considerations in specifying the
correct door controls:
• Does it satisfy the necessary fire regulations?
• Does it satisfy the requirements of the Special Educational Needs & Disability Act (SENDA)?
It is essential that the door closer:
• Is CE marked to BS EN1154
• Is CERTIFIRE approved
• Is set at a minimum spring strength of EN3
• Meets the requirements of SENDA
BS EN1154 Controlled Door Closing Devices
All dormakaba Door Closers are CE Marked to BS EN1154
and have been cycle tested to over 1 million cycles without
showing any appreciable wear. Under BS EN1154 the door
closer when fitted to a fire door must be set at minimum
spring strength of EN3.

CERTIFIRE Approved
CERTIFIRE are an independent approvals board for
the testing of fire doors and all associated ironmongery. It
is worth noting that an approved door will become invalid
if approved ironmongery is not fitted. All Door Closers are
CERTIFIRE approved.
SENDA (Special Education Needs & Disability Act)
The requirement of SENDA is that a person is not disadvantaged by their disability in gaining access around a
building. The specific performance of door closers in
meeting this requirement is detailed within Approved
Document M (ADM) in England and Wales / Section 3 in
Scotland / Part R in Northern Ireland, of the Building
Regulations and BS8300: 2009, Incorporating Amendment
No.1. This states: “…a door closer must produce an opening
force of below 30N between 0 and 30 degrees and below
22.5N between 30 and 60 degrees…”.
On a fire door this must be achieved at minimum spring
strength of EN3. Not all door closers available in the
market can meet the criteria. All dormakaba door closers
carry third party test evidence to demonstrate their ability
to comply with the requirements of ADM and BS8300.
