General
The IK3 operating units serve as switching elements for arming/disarming intrusion detection
systems as well as for AC function in conjunction with the IK3 evaluating unit and the correspond-
ing data carriers. Both optical and acoustical acknowledgement is possible.
The housing front can be subsequently replaced (in different colours).

IK data carrier
Storage media on which authorization data are saved are regarded as IK data carriers. IK data
carriers are available in various geometrical shapes.
The reading unit in the IK3 operating unit can read all IK2 data carriers used so far.
IK3 write/read data carriers where data is altered according to a special technique after every read
process can be used for additional security.
Due to the position of the transmission/reception antenna inside the different data carriers, a
different read position of the data carrier is required to the operating unit. The data carrier should
be held approximately in the
of this range.

sec. after using a data carrier, the reader switches to low current mode. If the data carrier is used
in conjuncti n with an operating unit in low current mode, it may take 1.2 sec. until it starts
operating. Evaluation takes place within 0.9 sec. when the write/read mode is activated.
Influence on the read process by other data
carriers:
In order to prevent several data carriers affecting
the read process, ensure that the desired data
carrier is held separately, if possible, in the
reading range.
