6.4.5.1 Connecting one or more readers
IMPORTANT
Users who wish to leave the underground car park are within a protected
area. Consequently, there is no need to re-verify authorisation for the door.
Greater convenience is provided by connecting one button in a parallel
circuit with another button (in the gatehouse) and positioning it near to the
exit within the protected area.
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
underground car park entrance features a locking device which is heavily
used. This means that each identification medium used here is verified on
the reader and, consequently, in the LSM database via the controller.
Authorisation changes, IDs to be blocked and time budgets are thus
efficiently managed.
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]).
Manipulation of unprotected electrical connections
Unprotected electrical connections can be short-circuited or manipulated in
another way.
1. Install electrical connections from buttons to the controller within
protected areas only.
2. Install electrical connections from the controller to the contactor or the
device being activated within protected areas only.
See Connecting one or more readers [} 55] and Connecting one or more
buttons [} 61] on wiring.
If you use one or two card readers, you may wire them either to the first,
second or third connection. If you wish to connect SmartOutput modules,
you may only use the connection on the third reader.
