Both public and
commercial premises must balance security, safety and
access. Although the challenges that face each are markedly
different, a great unifying factor is legislation.
In the last year, new standards and technology have changed
the face of the security sector. The challenge increasingly
is now to fit locks and access control products that meet
new British and European standards, yet still provide a high
degree of security against break-in or attempted theft in
both publicly and privately operated buildings.
The Disability Discrimination Act, for example, is designed
to encourage building owners, designers and tenants to make
permanent physical improvements to their premises so that
disabled people can gain access and make unaided use of the
facilities available.
Central to the purpose of this new legislation is ease of
access, making products such as automatic swing door
operators an ideal solution to a variety of access control
needs. In particular, swing door operators can be used on
main entrance doors and internal fire doors to provide free
and unrestricted access for disabled people throughout a
building.
Although many existing offices and public areas are
relatively straightforward to adapt, usually by the addition
of something as simple as ramps or automatic doors for
wheelchair access, companies often do not know where to
start when it comes to making premises accessible. Many
building owners and tenants are turning to the latest
innovations in access control, which meet the requirements
of legislation and can also be achieved within strict
budgets.
The latest range of innovative access control solutions are
designed to adhere to the new legislation - both for new and
existing buildings - as straightforward and cost effective
as possible, while ensuring that the security of the
building is not compromised.
Automatic swing door operators are an ideal solution to a
variety of access control needs, as they offer an efficient,
reliable, sophisticated and safe means of opening a hinged
door. They follow the DDA’s guidelines by giving disabled
people unimpeded entry and can be used on main entrance
doors and internal fire doors alike. In addition, when they
are used in conjunction with motor locks or solenoid locks,
automatic swing door operators can provide hands-free access
control without compromising building security.
Modern door operators offer a number of advanced features
that enable building managers to determine accurate and
precise operation, from initial opening speed to final
closing speed, hold open time, opening/closing force and
direction. The operator has a built-in safety mechanism that
prevents the door from closing if anything – or anyone –
is detected within the door’s immediate area.
Additionally, internal door operators can be programmed to
hold doors open for up to 60 seconds. These functions ensure
that individuals confined to wheelchairs or with walking
difficulties are able to move freely around a building at
their own pace.
Automatic door operators can also be connected to electric
locks so that a secure door can be released and opened by
remote control, i.e. from a wheelchair. Doors may also be
opened with impulse devices such as push buttons, contact
switches or card readers. In addition, for added security
and safety, door operators can be wired into alarm systems
and set so that, in the event of an emergency, the door
remains closed or open, whichever is required. A battery
backup allows the door operator to continue to work even in
the event of a power failure; this is critical in ensuring
disabled people have free access even in the event of an
emergency.
In addition, access can also be provided to all legitimate
visitors by means of a remote access switch controlled by a
receptionist or security personnel. This device can, when
linked through a door operator, withdraw the latchbolt of
the motor lock, allowing the door to swing open. On closure,
the bolt will automatically throw, ensuring complete
security is maintained. In the event of power failure, while
the bolt is thrown automatically, a mechanical override is
available as standard to provide emergency access.
The DDA is not the only source of regulatory change
effecting access control. New European product standards –
designed to secure safe and effective methods of escape –
have affected the specification of panic exit devices.
Indeed their impact is such that where safety is an issue,
only products meeting the BS EN 1125 and BS EN 179 standards
are now being considered.
Fire routes require a quick and safe exit, so standards such
as BS EN179 and BS EN1125 must be followed. Final exit doors
in particular can be operated using panic exit devices in
conjunction with a lock that will open under side pressure.
This type of device is available with mechanical or
electrical operation; when connected to a central security
system, electronic panic exit devices can improve levels of
flexibility and security, and can be monitored and operated
either remotely or centrally.
Electronically controlled panic exit devices combine access
control with anti-panic functions, allowing both local and
remote control of emergency exit doors by connecting a
series of doors to a central station which monitors the door
remotely. In addition, systems can be connected to the fire
alarm so that egress is assured in the case of an emergency.
European Building Hardware standards for electrically
controlled emergency exit systems in particular, the
forthcoming prEN13637 stipulates that all electrically
controlled emergency exit doors must open under a side
pressure of 1000N, yet be intrusion resistant. To meet this
specification electric locks are being introduced that offer
exceptional performance – the eff 351 for example has
been tested to release up to 5000N.
Modern panic exit systems add a greater degree of
intelligence to exit solutions. For instance, some devices
offer both electrical blocking (exit control) and monitoring
(system control), while others feature full monitoring with
electrical dogging (entrance control). While electrically
dogged bars remain locked when the power supply is cut –
i.e. they are fail secure – mechanical opening is always
retained allowing emergency exit doors to be used for more
than one purpose.
It is important to note that access needs must be
anticipated and provisions put in place, rather than making
changes only when a disabled person requires access to a
building. When securing any public venue, the challenge is
not only confined to granting the rights of passage to authorized
visitors but also refusing entry to undesirable elements,
such as vandals, thieves or terrorists. This can be achieved
by specifying appropriate locking systems and panic exit
hardware within access control systems, to safeguard a
building’s integrity, while creating an open, yet secure
and ultimately safe environment.
