6.4.4.3 Lift
The user can use their identification media to check authorisation while in
the car. If the user does not have an identification medium, but is expected,
they can still announce their arrival, using an intercom, for example.
Another person who is in the protected area can then let the user in by
pressing the connected button. The button can be installed in a gatehouse,
for example, which only allows external customers to enter during business
hours while users with identification media can come in at any time.
No-one can manipulate the data since communication is secured from the
reader to the controller and to LSM. When the data reach the controller, the
controller evaluates them. If there is a virtual network and connection to
LSM (Ethernet), the latest information is retrieved using the identification
medium; if not, the system used the last status saved internally. Depending
on the result of the evaluation, the controller triggers the required action,
such as actuate a relay.
If a virtual network is used, the system is ideal for use as a gateway. The
barrier is a locking device which is very heavily used. This means that
many identification media are already synchronised with the LSM database
before they reach the building entrance. As a result, there is less load on
the gateway on the building door. In this case, the reader should be
installed where it is visible for users to ensure that they can hear or see the
reader feedback signals.
The controller can be powered either via an external power supply unit or
via the network line. The controller, in turn, can power the reader. If the
voltage drop is too great, the reader can also be supplied by an external
power supply unit (see External power supply [} 57]).
Since a feed line needs to be installed for the barrier motor, the power
supply for the reader can be easily connected to this line. Power is reliably
supplied to the reader with a power supply unit, so the reader is not
affected by any voltage drops due to line length.
See Connecting one or more readers [} 55] and Connecting one or more
buttons [} 61] on wiring.
A lift is a special case. Lift cabs are usually connected to their environment
through a trailing cable. However, the number of lines within the trailing
cable is limited. The SREL3 ADV system requires a varying large number
of lines, depending on the configuration.
It is highly recommended to use one or several SmartOutput modules in a
lift to provide sufficient relay contacts. We also need to consider that the
controller should be mounted on top of the lift cab or a network connection
must be laid through the trailing cable.
If one or several SmartOutput modules are used, effective access
management can be implemented in the lift itself with authorisation required
for buttons for specific floors.
