used within police or military
establishments. Role based is more often
used in larger organisations where security
is extensive but granted based on individual
roles. The advantage here is that screening
can be reduced for those people requiring
access to non-secure areas.
Door entry systems are utilised on secure
doors through which visitors cannot gain
access via the access control system. They
allow visitors to draw attention to their
arrival via a call button, which alerts a
security desk or reception to their presence.
Call panels can be speaker-based but as
technology advances, very sophisticated
camera images can also be communicated.
Access control systems can be simple or
sophisticated – from digital keypads to
biometric devices activated by a pre-
programmed fingerprint or retina scan.
It’s perhaps easy to understand then, why
automatic doors and access control
products make perfect partners. As security
demands increase against a backdrop of
societal threats such as counter terrorism,
industrial espionage and the need to protect
vulnerable people and children, our
solutions and systems need to speak to each
other effectively.There are also practical day-to-day benefits.
When combined, they can control door
opening speeds, ‘hold open’ times and
closing speeds and forces to ensure that
once opened, door return to its secure
state consistently.
A common question arises when access-
controlled doors also need to be used as an
escape route. In such cases, they must allow
exit. A powered door operator can be easily
programmed to operate as a security door
in normal operation, but drive to a safe
condition in the event of a fire or
emergency alarm.Ken Price is managing director of the
