Sources of interference
Errors between transponder key and reading head
The connection between the reading head of the "Electronic cylindrical lock" and the
transponder key is triggered via RFID technology by induction.
If during the switching process of the reading head the transponder key is located next to other
transponder keys or RFID cards, this can cause mutual influences.
–
E.g. when the transponder key is kept in the purse with other RFID cards and the purse is
held in front of the reading head.
Such influences do not cause damage. However, it is possible that then the reading head does
not switch.
Errors of communication of the reading head with the management software of the "Smart
Access Point Pro"
The communication between the reading head and the management software of the "Smart
Access Point Pro" is carried out via the frequencies of Bluetooth.
Errors during installation:
■
–
The normal transmission range of 10 meters between the individual devices of the
"ABB-AccessControl" is influenced by the building structure. If the radio signals must
pass through a reinforced concrete wall, the transmission range can be reduced.
Errors during running operation:
■
–
The devices of the "ABB-AccessControl" are permanently installed. This causes no
problems due to changes of location.
–
Errors can be caused when foreign devices near the communication process send on
the same frequencies. E.g. wireless telephones or microwaves. The reading head may
then not switch. If the source of the error in the area is rectified, everything will function
again as usual.
Newly installed "Electronic cylindrical lock" cannot be operated
The "Electronic cylindrical lock" is being operated in a location different to the area of
■
application stored in the management software. That is why the communication path no
longer harmonizes with the original one. The "Electronic cylindrical lock" must be coupled
anew, see chapter 5.4.4 "Coupling the "Electronic cylindrical lock" with the "Smart Access
Point Pro"" on page 122.
The "Electronic cylindrical lock" was put into operation on a different "Smart Access Point
■
Pro".
–
The "Electronic cylindrical lock" must be uncoupled on the original "Smart Access Point
Pro" and then put into operation on the current "Smart Access Point Pro".
