be installed on the contacts. Users can press these buttons instead of using
an identification medium in a secured area. This improves user convenience
without losing control over the door status.
If the reader needs to be protected against vandalism, sabotage or the
effects of the weather, a protective housing can be fitted to the reader
(SREL2.COVER1).
Building entrance doors are a special case:
All users need to pass through one of the building entrance doors on a

daily basis.
Building entrance doors are exposed to the weather on one side.

Building entrance doors are in an unsecured area on one side.

It must also be possible to open building entrance doors without an

identification medium in an emergency at times.
If a virtual network is used, building entrance doors are ideal for use as a
gateway. The building entrance is a door which many users pass through
on a daily basis. 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.
Access events can be forwarded to a third-party system via the serial
interface.
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
