ELECTRIC LOCKS OFFER SOLUTION TO
CITY OF LONDON OFFICE BUILDING.
» » ARCHITECTURAL IRONMONGER G.
Johns and Sons of London were involved
with the specification for an access control
system at the office block in the City of
London, whereby the client wanted a
flexible access control system with the
minimum of ironmongery on the doors
and did not require the use of surface
mounted electro-magnetic locks. They
required a modern office appearance with
clean stylish lines, with a high level of
security and the flexibility to offer office
space to their clients.
Jeremy Barltrop of G. Johns chose to
use the Securefast ASEL2460 Electric
Escape Lock on the two doors on
each landing of the five story building
with Karcher Stainless Steel lever
handles and connected via heavy duty
conductor hinges to a reader on the
outside of the doors. The client did not
require overriding cylinders therefore
the Securefast lock was chosen for its
quality, easy of use and reliability. As the
latch bolt is magnetic, it latches when
the door is fully closed, which means
the closing pressure of the doors can
be light to overcome the force usually
required for a latch bolt spring. The lock
also automatically throws the deadbolt
when the door is fully closed increasing
the security on the doors, but both bolts
are fully withdrawn in one action on
the inside by the lever handle for safe
emergency egress. This enables the client
to control entry to each floor via the lift or
staircase with a proximity card, and allow
safe egress via the lever handle fitted to
the lock case.
The benefits of using the Securefast
Electric lock also means that the locking
and unlocking of the door is extremely
quiet with minimum sound from throwing
and withdrawing of the latch and
deadbolt, making the product ideal for a
quiet office.
Anti-pitting test
exceeds 3,000 hours
» » LOCK LOCK, THE NEW HIGH
security handle from Brisant Secure, has
spent over 3,000 hours – four MONTHS -
in independent corrosion testing, with no
sign of pitting or blistering. Just 240 hours,
or 10 days, of salt spray testing is required
to achieve the EN 1906:2012. The highest
corrosion grade measured is 480 hours.
“Pitting on door furniture is one of the
industry’s dirtiest secrets,” says Nick Dutton,
CEO of Brisant Secure. “In fact, Lock Lock
has spent longer in the salt spray chamber
than some handles I used to buy lasted on
the door. Many manufacturers only offer a
guarantee on performance, or a token one
on the finish. Some recommend stainless
steel for ‘coastal’ areas – but 63% of the UK
population live less than 9.3 miles from the
sea. And 36% live within just 3 miles! In fact,
most of us are near the coast, and the issues
we have in the UK with corrosion on door
handles reflects that. What might be fine for
inland Europe, America or Australia, just
isn’t suitable for an island like ours.”
Although stainless steel is often
promoted as a better anti-corrosion
(and more expensive) option, some
manufacturers have only tested it to
500 hours. Brisant has three Lock Lock
handles in the testing chamber in
polished gold, chrome, and white powder
coat. They’ve been sprayed with over 65kg
of salt so far, and not one of the finishes
has shown any signs of corrosion. Brisant
has increased Lock Lock’s initial 2-year
guarantee to 5 years and will go further if
the handles tested continue to perform.
Nick adds: “As manufacturers we can and
should do better. Lock Lock took 24 months
to develop. Each handle is coated twice with
copper and then twice with nickel, and its
designed with a seamless curve so there

are no edges or corners, traditional weak
spots for corrosion. The industry needs to
ask itself why its finish guarantees aren’t
anywhere near those for performance or
security. Homeowners expect their handles
to look good for years, not months. But all
too often the reality is sadly different.”
