Access Control |
It is essential that
access to the room is controlled and monitored.
Various options are available which range from
a simple mechanical digital lock, through card
readers, electronic tokens, fingerprint and iris
readers, to a live video screening for personal
vetting by a security guard.
These are connected to a means of locking/unlocking
the door, which may be an electronic retractable
lock keep, or a magnetic lock – which is
a large electro magnet.
It is important that these locks have either a
manual means of release from inside the room,
to enable occupants to escape in an emergency.
The locks may be arranged to fail safe, which
means they release when the electrical power to
them is switched off – usually when a manual
break glass fire alarm is activated. However such
an arrangement needs careful consideration –
see Pitfalls. |
