ELECTRONIC ACCESS CONTROL SYSTEMS
New DHF Technical Standard TS010 for Electro-Magnetic Locking Devices.
Kevin O’Reilly, Operations
and Technical Director for
Securefast plc explains the
new standard. Kevin was
appointed by the DHF to
Chair a sub-committee to
compile a Technical Standard
for Electro-Magnetic Locks.

The increasing popularity
of electronic access control
systems is contributing to
the market growth of electromagnetic locking devices and
electric releases, each of which
is forecast to outperform the
growth of mechanical locks
over the next few years. Access
Control systems are becoming
increasingly popular because
they provide a higher level
of security while offering
integrated opportunities
with time management and
building automation systems.
More Electro-Magnetic Locks
are being used on Security,
Escape and Fire Doors with no
test evidence for performance,
fire, environmental or security
holding force. ElectroMagnetic Locks are now being
used as part of security tests
such as PAS24:2012 (Enhanced
Security Performance
Requirements for Doorsets
and Windows in the UK) and
plans in the future are to use
them when testing to prEN
13637(Electrically Controlled
Exit Systems).
The Door and Hardware
Federation (DHF) had
concerns that manufacturers
and distributors are supplying
Electro-Magnetic Locks in to
the market with no evidence to
support that the products will
perform as well as stated in
76
THE JUL/AUG 2014 ISSUE
SPONSORED BY TRADELOCKS
the manufacturers catalogue.
When tested it was found that
a number of Electro-Magnetic
Locks which claimed a holding
force of 1200 lbs failed to reach
this level. The DHF Technical
Committee appointed
Kevin O’Reilly, Operations
and Technical Director for
Securefast plc to Chair a
sub-committee to compile
a Technical Standard for
Electro-Magnetic Locks, which
is now complete and can be
downloaded from the DHF
website http://www.dhfonline.

The new DHF Technical
Standard TS010:2014 for
Electro-Magnetic Locking
Devices is a performance
requirement standard that
will give specifiers and
manufacturers of doorsets the
confidence that the ElectroMagnetic locking device
will perform to the required
standard and covers Face to
Face Fixed, Mortice, Shear
and External Electro-Magnetic
Devices. Although the testing
method will test the holding
force as a direct pull, the
Electro-Magnet like many
individual products that are
tested to a product standard,
will perform differently in a
doorset test such as PAS24;
however TS010 will give the
manufacturer/distributor the
confidence of consistency
in Electro-Magnetic lock
performance. The eight digit
classification code includes
the 6th digit for the holding
force which falls in line with
the security classification used
by BSIA specifiers’ guide to
Access Control Systems, the
European Standard EN 501331 and the classification used by
NSI in their Code of Practice
for Planning, Installation and
Maintenance of Access Control
Systems NCP109.
Many of the Access Control
Codes of Practice recommend
a minimum holding force
grade of 3kN (675 lbs);
however TS010 allows mini
Electro-Magnetic Locks to
be tested and classified as
these are still popular for low
security applications. PAS24
testing will require a minimum
holding force of 5kN which is
grade 4 of TS010, equivalent
to grade 2 of BSIA specifiers’
guide to Access Control
Systems.
FIRE DOORS
With many Electro-Magnetic
Locks used on fire doors, with
TS010 specifiers will be able
to see from the classification
code that the individual
product has been tested or
accessed for use on fire doors,
which in the past has been
ignored by many installers as
no evidence is currently shown
on the packaging, instructions
or in manufacturerS’
catalogues.
Within the Classification
Code for TS010 specifiers
can identify features of the
product, such as the 4th
digital shows if the product is
supplied with safety straps and
bolts whilst the 7th digit shows
if the device is monitored
either visually - for example
with an LED Indicator or audio
using a buzzer etc. allowing
specifiers to know what they
are specifying.
